Subject: [PATCH AUTOSEL 6.11 107/244] tools/nolibc: powerpc: limit stack-protector workaround to GCC
From: Thomas Weißschuh <linux@...ssschuh.net>
[ 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
* works with __attribute__((__optimize__("-fno-stack-protector")))
