+Subject: [PATCH] Config.in.arch: Free UCLIBC_HAS_FPU setting from depending on UCLIBC_HAS_FLOATS
+
+UCLIBC_HAS_FLOATS and UCLIBC_HAS_FPU are denoting two different aspects.
+UCLIBC_HAS_FLOATS covers the floating point operations which has nothing
+to do if you have FPU or not.

+From: Salvatore Cro <salvatore.cro at st.com>
+
+Argp is an advanced support for parsing unix-style argument vectors.
+In addition to the common getopt interface, it provides automatic response
+to `--help' and `--version' options and use of custom parser in conjunction
+with argp native option parser, among others.
+Argp support is required by elfutils package and prelink.
+
+In uClibc argp functionalities has been moved from C library to libuargp.so
+Further the libc.so linker script contains an AS_NEEDED entry so that
+it doesn't need to link libuargp.so explicitely.

++         Argp is an interface for parsing unix-style argument vectors. Unlike
++         the common getopt interface, it provides many advanced features in
++         addition to parsing options, such as automatic output in response to
++         `--help' and `--version' options.
++         A library can export an argp option parser, which programs can easily
++         use in conjunction with their own option parser.
++         A new shared object "libuargp" is created. The "libc.so" linker script
++         contains the AS_NEEDED entry for getting the libuargp linked automatically.
++         Argp support is needed by elfutils libdw.
++
++         Most people can safely answer N.

++     REQUIRE_ORDER means don't recognize them as options;
++     stop option processing when the first non-option is seen.
++     This is what Unix does.

++     non-option ARGV-element as if it were the argument of an option
++     with character code 1.  Using `-' as the first character of the
++     list of option characters selects this mode of operation.
++
++     The special argument `--' forces an end of option-scanning regardless

++                               process, it's removed from the output entirely)
++     -r, --reverse, --gratuitously-long-reverse-option
++                               Reverse the order of any sort
++        --session[=SID]        Add the processes from the session SID (which
++                               defaults to the sid of the current process)
++
++    Here are some more options:
++     -f ZOT, --foonly=ZOT       Glork a foonly
++     -z, --zaza                 Snit a zar
++
++     -?, --help                 Give this help list
++        --usage                Give a short usage message
++     -V, --version              Print program version
++

++/* Argp example #3 -- a program with options and arguments using argp */
++
++/* This program uses the same features as example 2, and uses options and
++   arguments.
++
++   We now use the first four fields in ARGP, so here's a description of them:
++     OPTIONS  -- A pointer to a vector of struct argp_option (see below)
++     PARSER   -- A function to parse a single option, called by argp
++     ARGS_DOC -- A string describing how the non-option arguments should look
++     DOC      -- A descriptive string about this program; if it contains a
++                 vertical tab character (\v), the part after it will be
++                 printed *following* the options
++
++   The function PARSER takes the following arguments:
++     KEY  -- An integer specifying which option this is (taken
++             from the KEY field in each struct argp_option), or
++             a special key specifying something else; the only
++             special keys we use here are ARGP_KEY_ARG, meaning
++             a non-option argument, and ARGP_KEY_END, meaning
++             that all arguments have been parsed
++     ARG  -- For an option KEY, the string value of its
++             argument, or NULL if it has none
++     STATE-- A pointer to a struct argp_state, containing
++             various useful information about the parsing state; used here
++             are the INPUT field, which reflects the INPUT argument to
++             argp_parse, and the ARG_NUM field, which is the number of the
++             current non-option argument being parsed
++   It should return either 0, meaning success, ARGP_ERR_UNKNOWN, meaning the
++   given KEY wasn't recognized, or an errno value indicating some other
++   error.
++
++   Note that in this example, main uses a structure to communicate with the
++   parse_opt function, a pointer to which it passes in the INPUT argument to
++   argp_parse.  Of course, it's also possible to use global variables
++   instead, but this is somewhat more flexible.
++
++   The OPTIONS field contains a pointer to a vector of struct argp_option's;
++   that structure has the following fields (if you assign your option
++   structures using array initialization like this example, unspecified
++   fields will be defaulted to 0, and need not be specified):
++     NAME   -- The name of this option's long option (may be zero)
++     KEY    -- The KEY to pass to the PARSER function when parsing this option,
++               *and* the name of this option's short option, if it is a
++               printable ascii character
++     ARG    -- The name of this option's argument, if any
++     FLAGS  -- Flags describing this option; some of them are:
++                 OPTION_ARG_OPTIONAL -- The argument to this option is optional
++                 OPTION_ALIAS        -- This option is an alias for the
++                                        previous option
++                 OPTION_HIDDEN       -- Don't show this option in --help output
++     DOC    -- A documentation string for this option, shown in --help output
++
++   An options vector should be terminated by an option with all fields zero. */

+
+The "use BX" option is now a suggestion that BX be used if available.
+Use a macro to detect if BX is available at build time. If so, and
+the user requested it be used, then use it. Otherwise, error out.

+
+Rely on the compiler to be properly setup for the default ABI.
+
+When installing-headers, there are two cases:
+- NPTL: no issue, a cross-compiler is already expected
+- LinuxThreads: no issue, EABI/OABI has no impact on installed headers.

+Subject: [PATCH 3/7] ARM: remove sub-arch/variants selection from menuconfig
+Date: Sun,  9 Jan 2011 01:45:06 +0100
+Message-Id: <1294533910-19305-4-git-send-email-yann.morin.1998@anciens.enib.fr>
+X-Mailer: git-send-email 1.7.1
+In-Reply-To: <1294533910-19305-1-git-send-email-yann.morin.1998@anciens.enib.fr>
+References: <1294533910-19305-1-git-send-email-yann.morin.1998@anciens.enib.fr>
+
+Rely on the compiler to be correctly set up to generate
+appropriate code for the target variant.
+
+This exposes the Thumb option, as it is no longer auto-selected.
+The "Use BX" no longer depends on supported CPU to be selected,
+so it now defaults to 'n' as it shall work by default on CPUs
+that do not have BX.

+-	  This is the processor type of your CPU. This information is used for
+-	  optimizing purposes.  To build a library that will run on all ARMCPU
+-	  types (albeit not optimally fast), you can specify "Generic Arm" here.
+-	  If you pick anything other than "Generic Arm", there is no guarantee 
+-	  that uClibc will even run on anything other than the selected
+-	  processor type.
+-
+-	  Here are the settings recommended for greatest speed:
+-	  - "Generic Arm" select this if your compiler is already setup to
+-	    optimize things properly, or if you want to run on pretty much
+-	    everything, or you just don't much care.
+-	  - For anything else, pick the ARM core type that best matches the
+-	    cpu you will be using on your device.
+-
+-	  If you don't know what to do, choose "Generic Arm".

+Subject: [PATCH 2/7] ARM: introduce blind options to select & force THUMB mode
+Date: Sun,  9 Jan 2011 01:45:05 +0100

+References: <1294533910-19305-1-git-send-email-yann.morin.1998@anciens.enib.fr>
+
+Add three new blind options to set use of Thumb mode:
+- COMPILE_IN_THUMB_MODE
+  - if set, CFLAGS will contain -mthumb
+  - if unset, the compiler's default is used
+- HAS_THUMB
+  - CPUS with Thumb instruction set can select this
+  - use of BX depends on this
+- FORCE_THUMB
+  - CPUs that are Thumb-only must select this
+  - this selects: HAS_THUMB, COMPILE_IN_THUMB_MODE and USE_BX
+
+Also, remove leading space in Rules.mak.
