* aclocal/check-cxx.m4: Add AC_SUBST(CPLUS_LD_LIBS) * aclocal/prog-cc.m4: Cleanup comments, require RTEMS_ENABLE_GCC28, add automake conditionals RTEMS_USE_GCC, RTEMS_USE_GCC272. * automake/compile.am: Replaced. * automake/local.am: Remove building variant handling.

## The section below is based on make/compilers/gcc-target-default.cfg
|

## used in former versions of RTEMS.
|

|
||||
##
|
||||
## Set up the flags for the toolchains:
|
||||
##
|
||||
## We are considering 3 different building schemes here:
|
||||
## * Using gcc's being able to accept -specs (aka gcc-2.8 building scheme)
|
||||
## * Using gcc's not being able to accept -specs (aka gcc-2.7.2 building
|
||||
## scheme)
|
||||
## * Using third party toolchains (aka non-gcc building scheme)
|
||||
##
|
||||
## Automake conditionals in use:
|
||||
## RTEMS_USE_GCC .. if we are using GCC
|
||||
## RTEMS_USE_GCC272 .. if using gcc and if requested not to apply
|
||||
## gcc <= 2.7.2 incompatible rules
|
||||
|
||||
## NOTES:
|
||||
## * The gcc-2.8 building scheme is the nominal building scheme and
|
||||
## is actively supported.
|
||||
## * The gcc-2.7.2 building scheme is not supported by all BSPs and
|
||||
## is not extensively tested.
|
||||
## * The non-gcc building scheme requires manually setting up environment
|
||||
## variables and is hardly tested at all
|
||||
|
||||
## CFLAGS_OPTIMIZE_V, CFLAGS_DEBUG_V, CFLAGS_PROFILE_V are the values we
|
||||
## would want the corresponding macros to be set to.
|
||||
##
|
||||
## CFLAGS_OPTIMIZE, CFLAGS_DEBUG, CFLAGS_PROFILE are set by the
|
||||
## 'VARIANT=<OPTIMIZE|DEBUG|PROFILE>' targets to their _V values.
|
||||
|
||||
## XCPPFLAGS, XCFLAGS, XCXXFLAGS, XASFLAGS
