Subject: hsa: Fix bootstrap with older host compilers
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=cfded69eea33fe75655775dc4bf388f16d54eb4a;p=thirdparty%2Fgcc.git

hsa: Fix bootstrap with older host compilers

We didn't have __builtin_swap16 on all targets before GCC 4.8; hsa-brig
tries to use it if the host GCC is 4.6 or up though, breaking bootstrap.
This trivial patch fixes it.

Noticed on gcc22.


	* has-brig.c (lendian16): Don't try to use __builtin_bswap16
	unless compiling with at least GCC-4.8.
