+/*
+ * "Optimize" a list of dependencies as spit out by gcc -MD
+ * for the kernel build
+ * ===========================================================================
+ *
+ * Author Kai Germaschewski
+ * Copyright 2002 by Kai Germaschewski <kai.germaschewski@gmx.de>
+ *
+ * This software may be used and distributed according to the terms
+ * of the GNU General Public License, incorporated herein by reference.
+ *
+ *
+ * Introduction:
+ *
+ * gcc produces a very nice and correct list of dependencies which
+ * tells make when to remake a file.
+ *
+ * To use this list as-is however has the drawback that virtually
+ * every file in the kernel includes autoconf.h.
+ *
+ * If the user re-runs make *config, autoconf.h will be
+ * regenerated. make notices that and will rebuild every file which
+ * includes autoconf.h, i.e. basically all files. This is extremely
+ * annoying if the user just changed CONFIG_HIS_DRIVER from n to m.
+ *
+ * So we play the same trick that "mkdep" played before. We replace
+ * the dependency on autoconf.h by a dependency on every config
+ * option which is mentioned in any of the listed prequisites.
+ *
+ * kconfig populates a tree in include/config/ with an empty file
+ * for each config symbol and when the configuration is updated
+ * the files representing changed config options are touched
+ * which then let make pick up the changes and the files that use
+ * the config symbols are rebuilt.
+ *
+ * So if the user changes his CONFIG_HIS_DRIVER option, only the objects
+ * which depend on "include/linux/config/his/driver.h" will be rebuilt,
+ * so most likely only his driver ;-)
+ *
+ * The idea above dates, by the way, back to Michael E Chastain, AFAIK.
+ *
+ * So to get dependencies right, there are two issues:
+ * o if any of the files the compiler read changed, we need to rebuild
+ * o if the command line given to the compile the file changed, we
+ * better rebuild as well.
+ *
+ * The former is handled by using the -MD output, the later by saving
+ * the command line used to compile the old object and comparing it
+ * to the one we would now use.
+ *
+ * Again, also this idea is pretty old and has been discussed on
+ * kbuild-devel a long time ago. I don't have a sensibly working
+ * internet connection right now, so I rather don't mention names
+ * without double checking.
+ *
+ * This code here has been based partially based on mkdep.c, which
+ * says the following about its history:
+ *
+ * Copyright abandoned, Michael Chastain, <mailto:mec@shout.net>.
+ * This is a C version of syncdep.pl by Werner Almesberger.
+ *
+ *
+ * It is invoked as
+ *
+ * fixdep <depfile> <target> <cmdline>
+ *
+ * and will read the dependency file <depfile>
+ *
+ * The transformed dependency snipped is written to stdout.
+ *
+ * It first generates a line
+ *
+ * cmd_<target> = <cmdline>
+ *
+ * and then basically copies the .<target>.d file to stdout, in the
+ * process filtering out the dependency on autoconf.h and adding
+ * dependencies on include/config/my/option.h for every
+ * CONFIG_MY_OPTION encountered in any of the prequisites.
+ *
+ * It will also filter out all the dependencies on *.ver. We need
+ * to make sure that the generated version checksum are globally up
+ * to date before even starting the recursive build, so it's too late
+ * at this point anyway.
+ *
+ * The algorithm to grep for "CONFIG_..." is bit unusual, but should
+ * be fast ;-) We don't even try to really parse the header files, but
+ * merely grep, i.e. if CONFIG_FOO is mentioned in a comment, it will
+ * be picked up as well. It's not a problem with respect to
+ * correctness, since that can only give too many dependencies, thus
+ * we cannot miss a rebuild. Since people tend to not mention totally
+ * unrelated CONFIG_ options all over the place, it's not an
+ * efficiency problem either.
+ *
+ * (Note: it'd be easy to port over the complete mkdep state machine,
+ * but I don't think the added complexity is worth it)
+ */
+/*
+ * Note 2: if somebody writes HELLO_CONFIG_BOOM in a file, it will depend onto
+ * CONFIG_BOOM. This could seem a bug (not too hard to fix), but please do not
+ * fix it! Some UserModeLinux files (look at arch/um/) call CONFIG_BOOM as
+ * UML_CONFIG_BOOM, to avoid conflicts with /usr/include/linux/autoconf.h,
+ * through arch/um/include/uml-config.h; this fixdep "bug" makes sure that
+ * those files will have correct dependencies.

+
+Diffconfig is a simple utility for comparing two .config files.
+Using standard diff to compare .config files often includes extraneous and
+distracting information. This utility produces sorted output with only the
+changes in configuration values between the two files.
+
+Added and removed items are shown with a leading plus or minus, respectively.
+Changed items show the old and new values on a single line.
+
+If -m is specified, then output will be in "merge" style, which has the
+changed and new values in kernel config option format.
+
+If no config files are specified, .config and .config.old are used.
+
+Example usage:
+ $ diffconfig .config config-with-some-changes
+-EXT2_FS_XATTR n
+-EXT2_FS_XIP n
+ CRAMFS n -> y
+ EXT2_FS y -> n

+ - The only way there can be no lookahead present (in yychar) is if

+ detecting the absence of a lookahead is sufficient to determine
+ that there is no unexpected or expected token to report. In that
+ case, just report a simple "syntax error".
+ - Don't assume there isn't a lookahead just because this state is a
+ consistent state with a default action. There might have been a
+ previous inconsistent state, consistent state with a non-default
+ action, or user semantic action that manipulated yychar.
+ - Of course, the expected token list depends on states to have
+ correct lookahead information, and it depends on the parser not
+ to perform extra reductions after fetching a lookahead from the
+ scanner and before detecting a syntax error. Thus, state merging
+ (from LALR or IELR) and default reductions corrupt the expected

+/*
+ * Changes by Clifford Wolf (god@clifford.at)
+ *
+ * [ 1998-06-13 ]
+ *
+ * *) A bugfix for the Page-Down problem
+ *
+ * *) Formerly when I used Page Down and Page Up, the cursor would be set
+ * to the first position in the menu box. Now lxdialog is a bit
+ * smarter and works more like other menu systems (just have a look at
+ * it).
+ *
+ * *) Formerly if I selected something my scrolling would be broken because
+ * lxdialog is re-invoked by the Menuconfig shell script, can't
+ * remember the last scrolling position, and just sets it so that the
+ * cursor is at the bottom of the box. Now it writes the temporary file
+ * lxdialog.scrltmp which contains this information. The file is
+ * deleted by lxdialog if the user leaves a submenu or enters a new
+ * one, but it would be nice if Menuconfig could make another "rm -f"
+ * just to be sure. Just try it out - you will recognise a difference!
+ *
+ * [ 1998-06-14 ]
+ *
+ * *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ * and menus change their size on the fly.
+ *
+ * *) If for some reason the last scrolling position is not saved by
+ * lxdialog, it sets the scrolling so that the selected item is in the
+ * middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.

+"Overview\n"
+"--------\n"
+"This interface lets you select features and parameters for the build.\n"
+"Features can either be built-in, modularized, or ignored. Parameters\n"
+"must be entered in as decimal or hexadecimal numbers or text.\n"
+"\n"
+"Menu items beginning with following braces represent features that\n"
+" [ ] can be built in or removed\n"
+" < > can be built in, modularized or removed\n"
+" { } can be built in or modularized (selected by other feature)\n"
+" - - are selected by other feature,\n"
+"while *, M or whitespace inside braces means to build in, build as\n"
+"a module or to exclude the feature respectively.\n"
+"\n"
+"To change any of these features, highlight it with the cursor\n"
+"keys and press <Y> to build it in, <M> to make it a module or\n"
+"<N> to remove it. You may also press the <Space Bar> to cycle\n"
+"through the available options (i.e. Y->N->M->Y).\n"
+"\n"
+"Some additional keyboard hints:\n"
+"\n"
+"Menus\n"
+"----------\n"
+"o Use the Up/Down arrow keys (cursor keys) to highlight the item you\n"
+" wish to change or the submenu you wish to select and press <Enter>.\n"
+" Submenus are designated by \"--->\", empty ones by \"----\".\n"
+"\n"
+" Shortcut: Press the option's highlighted letter (hotkey).\n"
+" Pressing a hotkey more than once will sequence\n"
+" through all visible items which use that hotkey.\n"
+"\n"
+" You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll\n"
+" unseen options into view.\n"
+"\n"
+"o To exit a menu use the cursor keys to highlight the <Exit> button\n"
+" and press <ENTER>.\n"
+"\n"
+" Shortcut: Press <ESC><ESC> or <E> or <X> if there is no hotkey\n"
+" using those letters. You may press a single <ESC>, but\n"
+" there is a delayed response which you may find annoying.\n"
+"\n"
+" Also, the <TAB> and cursor keys will cycle between <Select>,\n"
+" <Exit>, <Help>, <Save>, and <Load>.\n"
+"\n"
+"o To get help with an item, use the cursor keys to highlight <Help>\n"
+" and press <ENTER>.\n"
+"\n"
+" Shortcut: Press <H> or <?>.\n"
+"\n"
+"o To toggle the display of hidden options, press <Z>.\n"
+"\n"
+"\n"
+"Radiolists (Choice lists)\n"
+"-----------\n"
+"o Use the cursor keys to select the option you wish to set and press\n"
+" <S> or the <SPACE BAR>.\n"
+"\n"
+" Shortcut: Press the first letter of the option you wish to set then\n"
+" press <S> or <SPACE BAR>.\n"
+"\n"
+"o To see available help for the item, use the cursor keys to highlight\n"
+" <Help> and Press <ENTER>.\n"
+"\n"
+" Shortcut: Press <H> or <?>.\n"
+"\n"
+" Also, the <TAB> and cursor keys will cycle between <Select> and\n"
+" <Help>\n"
+"\n"
+"\n"
+"Data Entry\n"
+"-----------\n"
+"o Enter the requested information and press <ENTER>\n"
+" If you are entering hexadecimal values, it is not necessary to\n"
+" add the '0x' prefix to the entry.\n"
+"\n"
+"o For help, use the <TAB> or cursor keys to highlight the help option\n"
+" and press <ENTER>. You can try <TAB><H> as well.\n"
+"\n"
+"\n"
+"Text Box (Help Window)\n"
+"--------\n"
+"o Use the cursor keys to scroll up/down/left/right. The VI editor\n"
+" keys h,j,k,l function here as do <u>, <d>, <SPACE BAR> and <B> for\n"
+" those who are familiar with less and lynx.\n"
+"\n"
+"o Press <E>, <X>, <q>, <Enter> or <Esc><Esc> to exit.\n"
+"\n"
+"\n"
+"Alternate Configuration Files\n"
+"-----------------------------\n"
+"Menuconfig supports the use of alternate configuration files for\n"
+"those who, for various reasons, find it necessary to switch\n"
+"between different configurations.\n"
+"\n"
+"The <Save> button will let you save the current configuration to\n"
+"a file of your choosing. Use the <Load> button to load a previously\n"
+"saved alternate configuration.\n"
+"\n"
+"Even if you don't use alternate configuration files, but you find\n"
+"during a Menuconfig session that you have completely messed up your\n"
+"settings, you may use the <Load> button to restore your previously\n"
+"saved settings from \".config\" without restarting Menuconfig.\n"
+"\n"
+"Other information\n"
+"-----------------\n"
+"If you use Menuconfig in an XTERM window, make sure you have your\n"
+"$TERM variable set to point to an xterm definition which supports\n"
+"color. Otherwise, Menuconfig will look rather bad. Menuconfig will\n"
+"not display correctly in an RXVT window because rxvt displays only one\n"
+"intensity of color, bright.\n"
+"\n"
+"Menuconfig will display larger menus on screens or xterms which are\n"
+"set to display more than the standard 25 row by 80 column geometry.\n"
+"In order for this to work, the \"stty size\" command must be able to\n"
+"display the screen's current row and column geometry. I STRONGLY\n"
+"RECOMMEND that you make sure you do NOT have the shell variables\n"
+"LINES and COLUMNS exported into your environment. Some distributions\n"
+"export those variables via /etc/profile. Some ncurses programs can\n"
+"become confused when those variables (LINES & COLUMNS) don't reflect\n"
+"the true screen size.\n"
+"\n"
+"Optional personality available\n"
+"------------------------------\n"
+"If you prefer to have all of the options listed in a single menu,\n"
+"rather than the default multimenu hierarchy, run the menuconfig with\n"
+"MENUCONFIG_MODE environment variable set to single_menu. Example:\n"
+"\n"
+"make MENUCONFIG_MODE=single_menu menuconfig\n"
+"\n"
+"<Enter> will then unroll the appropriate category, or enfold it if it\n"
+"is already unrolled.\n"
+"\n"
+"Note that this mode can eventually be a little more CPU expensive\n"
+"(especially with a larger number of unrolled categories) than the\n"
+"default mode.\n"
+"\n"
+"Different color themes available\n"
+"--------------------------------\n"
+"It is possible to select different color themes using the variable\n"
+"MENUCONFIG_COLOR. To select a theme use:\n"
+"\n"
+"make MENUCONFIG_COLOR=<theme> menuconfig\n"
+"\n"
+"Available themes are\n"
+" mono => selects colors suitable for monochrome displays\n"
+" blackbg => selects a color scheme with black background\n"
+" classic => theme with blue background. The classic look\n"
+" bluetitle => an LCD friendly version of classic. (default)\n"

+# It's simple enough to figure out how this works.
+# If not, then you can ask me at stripconfig@goodmis.org
+#
+# What it does?
+#
+# If you have installed a Linux kernel from a distribution
+# that turns on way too many modules than you need, and
+# you only want the modules you use, then this program
+# is perfect for you.
+#
+# It gives you the ability to turn off all the modules that are
+# not loaded on your system.
+#
+# Howto:
+#
+# 1. Boot up the kernel that you want to stream line the config on.
+# 2. Change directory to the directory holding the source of the
+# kernel that you just booted.
+# 3. Copy the configuraton file to this directory as .config
+# 4. Have all your devices that you need modules for connected and
+# operational (make sure that their corresponding modules are loaded)
+# 5. Run this script redirecting the output to some other file
+# like config_strip.
+# 6. Back up your old config (if you want too).
+# 7. copy the config_strip file to .config
+# 8. Run "make oldconfig"
+#
+# Now your kernel is ready to be built with only the modules that
+# are loaded.
+#
+# Here's what I did with my Debian distribution.
+#
+# cd /usr/src/linux-2.6.10
+# cp /boot/config-2.6.10-1-686-smp .config
+# ~/bin/streamline_config > config_strip
+# mv .config config_sav
+# mv config_strip .config
+# make oldconfig

+ for details. YYERROR is fine as it does not invoke this

+ - If this state is a consistent state with a default action, then
+ the only way this function was invoked is if the default action
+ is an error action. In that case, don't check for expected
+ tokens because there are none.
+ - The only way there can be no lookahead present (in yychar) is if
+ this state is a consistent state with a default action. Thus,
+ detecting the absence of a lookahead is sufficient to determine
+ that there is no unexpected or expected token to report. In that
+ case, just report a simple "syntax error".
+ - Don't assume there isn't a lookahead just because this state is a
+ consistent state with a default action. There might have been a
+ previous inconsistent state, consistent state with a non-default
+ action, or user semantic action that manipulated yychar.
+ - Of course, the expected token list depends on states to have
+ correct lookahead information, and it depends on the parser not
+ to perform extra reductions after fetching a lookahead from the
+ scanner and before detecting a syntax error. Thus, state merging
+ (from LALR or IELR) and default reductions corrupt the expected
+ token list. However, the list is correct for canonical LR with
+ one exception: it will still contain any token that will not be
+ accepted due to an error action in a later state.

+Script to verify VxMicro projects can share a set of common kernel libs
+
+The sanity check builds a selection of sample of projects supported by the
+specified BSP variant; if no BSP has been specified, a default BSP for each
+project is used. The script also runs each sample project using QEMU, where
+possible; if desired the script can be instructed to skip the QEMU execution
+step.
+
+The script returns 0 on success. If an error is encountered at any point
+the script returns the exit value of the command that failed, the function
+and line of the script where the error was detected, as well as the full path
+of the script (to help debug path issues).
+
+*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=
+
+QEMU output from a project is sent to a log file identified by the script;
+it is typically located in the associated sample project directory.
+You can monitor execution by doing 'tail -f <log filename>' in another shell.
+
+A project's log file is normally retained only if execution fails; however,
+invoking the script with the '-l' option keeps the log file in all cases.
+
+*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=
+
+All object code and executable files persist after completion. Re-run the script

+Script to verify VxMicro projects can be built out of tree with a BSP
+residing out of tree.
+
+The sanity check builds a selection of sample of projects supported by the
+specified BSP variant; if no BSP has been specified, a default BSP for each
+project is used. The script also runs each sample project using QEMU, where
+possible; if desired the script can be instructed to skip the QEMU execution
+step.
+
+BSPs and samples are copied to:
+ VXMICRO_BASE/../sanity/bsp
+ VXMICRO_BASE/../sanity/samples
+
+The script returns 0 on success. If an error is encountered at any point
+the script returns the exit value of the command that failed, the function
+and line of the script where the error was detected, as well as the full path
+of the script (to help debug path issues).
+
+*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=
+
+QEMU output from a project is sent to a log file identified by the script;
+it is typically located in the associated sample project directory.
+You can monitor execution by doing 'tail -f <log filename>' in another shell.
+
+A project's log file is normally retained only if execution fails; however,
+invoking the script with the '-l' option keeps the log file in all cases.
+
+*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=
+
+All object code and executable files persist after completion. Re-run the script
+with the '-c' option to delete the sample project object code and log files.

+Script to sanitize the standard portion of VxMicro.

+The sanity check builds all sample projects supported by the specified BSP
+variant; if no BSP has been specified, a default BSP for each project is used.
+The script also runs each sample project using QEMU, where possible; if desired
+the script can be instructed to skip the QEMU execution step.
+
+The script returns 0 on success. If an error is encountered at any point
+the script returns the exit value of the command that failed, the function
+and line of the script where the error was detected, as well as the full path
+of the script (to help debug path issues).

+
+QEMU output from a project is sent to a log file identified by the script;
+it is typically located in the associated sample project directory.
+You can monitor execution by doing 'tail -f <log filename>' in another shell.
+
+A project's log file is normally retained only if execution fails; however,
+invoking the script with the '-l' option keeps the log file in all cases.
+
+*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=*-=
+
+All object code and executable files persist after completion. Re-run the script
+with the '-c' option to delete the sample project object code and log files.

+Script to sanitize VxMicro.
+
+The full sanity check consists of the following phases:
+
+ - Rebuild host tools to ensure they are compatible with the rest of VxMicro.
+ - Run "footprint_chk" to characterize the footprint of VxMicro.
+ - Run "regression_chk" to sanitize the standard portion of VxMicro.
+ - Run "common-klibs_chk" to verify if projects can share a set of common kernel libs
+ - Run "out-of-tree_chk" to verify if projects and BSPs can reside outside the normal VxMicro tree.
+
+The full sanity check is run by default. If desired, some steps can be omitted
+by using the available command options.

+ * A state transition function alters the global #if processing state

+ *
+ * Nesting is handled by keeping a stack of states; some transition
+ * functions increase or decrease the depth. They also maintain the
+ * ignore state on a stack. In some complicated cases they have to
+ * alter the preprocessor directive, as follows.
+ *
+ * When we have processed a group that starts off with a known-false
+ * #if/#elif sequence (which has therefore been deleted) followed by a
+ * #elif that we don't understand and therefore must keep, we edit the
+ * latter into a #if to keep the nesting correct. We use strncpy() to
+ * overwrite the 4 byte token "elif" with "if " without a '\0' byte.
+ *
+ * When we find a true #elif in a group, the following block will
+ * always be kept and the rest of the sequence after the next #elif or
+ * #else will be discarded. We edit the #elif into a #else and the
+ * following directive to #endif since this has the desired behaviour.
+ *
+ * "Dodgy" directives are split across multiple lines, the most common
+ * example being a multi-line comment hanging off the right of the
+ * directive. We can handle them correctly only if there is no change
+ * from printing to dropping (or vice versa) caused by that directive.
+ * If the directive is the first of a group we have a choice between
+ * failing with an error, or passing it through unchanged instead of
+ * evaluating it. The latter is not the default to avoid questions from
+ * users about unifdef unexpectedly leaving behind preprocessor directives.
