Hi all,
As part of the SWITCHABLE_TARGET work I inadvertently changed the
behaviour of -mgeneral-regs-only with respect to the .arch directives
that we emit.
The behaviour of -mgeneral-regs-only in GCC 5 and earlier is such that
it disallows the usage of FP/SIMD registers but does *not* stop the
compiler from
emitting the +fp,+simd etc extensions in the .arch directive of the
generated assembly. This is to accommodate users who may want to write
inline assembly
in a file compiled with -mgeneral-regs-only.
This patch restores the trunk behaviour in that respect to that of GCC
5 and the documentation for the option is tweaked a bit to reflect that.
Bootstrapped and tested on aarch64.
Ok for trunk?
Thanks,
Kyrill

Do not alter target_flags due to TARGET_GENERAL_REGS_ONLY_P.
* doc/invoke.texi (AArch64 options): Mention that
-mgeneral-regs-only
does not affect the assembler directives.
