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
27## NOTES:
28## * The gcc-2.8 building scheme is the nominal building scheme and
29##   is actively supported.
30## * The non-gcc building scheme requires manually setting up environment
31##   variables and is hardly tested at all
32
33## CFLAGS_OPTIMIZE_V, CFLAGS_DEBUG_V, CFLAGS_PROFILE_V are the values we
34## would want the corresponding macros to be set to.
35##
36## CFLAGS_OPTIMIZE, CFLAGS_DEBUG, CFLAGS_PROFILE are set by the
37## 'VARIANT=<OPTIMIZE|DEBUG|PROFILE>' targets to their _V values.
38
39## XCPPFLAGS, XCFLAGS, XCXXFLAGS, XASFLAGS
40## are used to add flags from the shell
41## cf. make.info ("Implicit rules/variables" for details)
