Tested with .../configure --target=c6x-uclinux [...] && make all-gcc,
ok for trunk?
-- >8 --
Currently, cross-compiling with --target=c6x-uclinux (and several other)
fails due to:
../../src/gcc/config/linux.h:221:45: error:
'linux_fortify_source_default_level' was not declared in this scope
#define TARGET_FORTIFY_SOURCE_DEFAULT_LEVEL linux_fortify_source_default_level
In the PR Andrew mentions that another fix would be in config.gcc,
but really, here I meant to use the target hook for glibc only, not
uclibc. This trivial patch fixes the build problem. It means that
-fhardened with uclibc will use -D_FORTIFY_SOURCE=2 and not =3.
PR target/112762
gcc/ChangeLog:
* config/linux.h: Redefine TARGET_FORTIFY_SOURCE_DEFAULT_LEVEL for
glibc only.
