     6## NOTE: This file is rather immature and has to be considered to be
     7## almost experimental.

     9## Expect frequent changes -- It deserves to be cleaned up :(
     10## -------------------------------------------------------------------------
     11
     12## The section below is based on make/compilers/gcc-target-default.cfg
     13## used in former versions of RTEMS.
     14
     15##
     16## Set up the flags for the toolchains:
     17##
     18## We are considering 3 different building schemes here:
     19## * Using gcc's being able to accept -specs (aka gcc-2.8 building scheme)
     20## * Using gcc's not being able to accept -specs (aka gcc-2.7.2 building
     21##   scheme)
     22## * Using third party toolchains (aka non-gcc building scheme)
     23##
     24## Automake conditionals in use:
     25## RTEMS_USE_GCC     .. if we are using GCC
     26## RTEMS_USE_GCC272  .. if using gcc and if requested not to apply
     27##                      gcc <= 2.7.2 incompatible rules
     28
     29## NOTES:
     30## * The gcc-2.8 building scheme is the nominal building scheme and
     31##   is actively supported.
     32## * The gcc-2.7.2 building scheme is not supported by all BSPs and
     33##   is not extensively tested.
     34## * The non-gcc building scheme requires manually setting up environment
     35##   variables and is hardly tested at all
     36
     37## CFLAGS_OPTIMIZE_V, CFLAGS_DEBUG_V, CFLAGS_PROFILE_V are the values we
     38## would want the corresponding macros to be set to.
     39##
     40## CFLAGS_OPTIMIZE, CFLAGS_DEBUG, CFLAGS_PROFILE are set by the
     41## 'VARIANT=<OPTIMIZE|DEBUG|PROFILE>' targets to their _V values.
     42
     43## XCPPFLAGS, XCFLAGS, XCXXFLAGS, XASFLAGS
     44## are used to add flags from the shell
     45## cf. make.info ("Implicit rules/variables" for details)
