## NOTE: This file is rather immature and has to be considered to be
|
|
## almost experimental.
|
|
##
|
|
## Expect frequent changes -- It deserves to be cleaned up :(

## -------------------------------------------------------------------------

## 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
|
|
|
|
## NOTES:
|
|
## * The gcc-2.8 building scheme is the nominal building scheme and
|
|
## is actively supported.
|
|
## * 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
|
|
## are used to add flags from the shell
|
|
## cf. make.info ("Implicit rules/variables" for details)
