+UCLIBC_HAS_FLOATS and UCLIBC_HAS_FPU are denoting two different aspects.
+UCLIBC_HAS_FLOATS covers the floating point operations which has nothing

+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.

++
++/* 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.

+Date: Sun, 9 Jan 2011 01:45:08 +0100

+References: <1294533910-19305-1-git-send-email-yann.morin.1998@anciens.enib.fr>
+
+The check for __USE_BX__ will be available in bits/arm_asm.h,
+so the latter must be included wherever the former is used.

+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.

+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.

+Subject: [PATCH 2/7] ARM: introduce blind options to select & force THUMB mode
+Date: Sun, 9 Jan 2011 01:45:05 +0100
+Message-Id: <1294533910-19305-3-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>
+
+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.
