* gcc.target/powerpc/pr79004.c: Add -mfloat128 to the test
options. Fix up the syntax for using \m and \M.
From-SVN: r244561
Currently, on PowerPC, code compiled with -fstack-protector will load
the canary from -0x7010(13) (for -m64) or from -0x7008(2) (for -m32)
if GCC was compiled against GNU libc 2.4 or newer or some other libc
that supports -fstack-protector, and from the global variable
__stack_chk_guard otherwise.
This does not work well for Linux and other OS kernels and similar.
For such non-standard applications, this patch creates a few new
command-line options. The relevant new use cases are:
-mstack-protector-guard=global
Use the __stack_chk_guard variable, no matter how this GCC was
configured.
-mstack-protector-guard=tls
Use the canary from TLS. This will error out if this GCC was built
with a C library that does not support it.
-mstack-protector-guard=tls -mstack-protector-register=<reg>
-mstack-protector-offset=<offset>
Load the canary from offset <off> from base register <reg>.

This patch simplifies the handling of EH return. We force the use of the
frame pointer so the return location is always at FP + 8. This means we
can emit a simple volatile access in EH_RETURN_HANDLER_RTX without needing md
patterns, splitters and frame offset calculations. The new implementation also
fixes various bugs in aarch64_final_eh_return_addr, which does not work with
-fomit-frame-pointer, alloca or outgoing arguments.
