[PATCH AUTOSEL 6.11 107/244] tools/nolibc: powerpc: limit stack-protector workaround to GCC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Thomas Weißschuh <linux@xxxxxxxxxxxxxx>

[ Upstream commit 1daea158d0aae0770371f3079305a29fdb66829e ]

As mentioned in the comment, the workaround for
__attribute__((no_stack_protector)) is only necessary on GCC.
Avoid applying the workaround on clang, as clang does not recognize
__attribute__((__optimize__)) and would fail.

 /* FIXME: For 32-bit PowerPC, with newer gcc compilers (e.g. gcc 13.1.0),
  * "omit-frame-pointer" fails with __attribute__((no_stack_protector)) but
