From 939264d3a37d0645de08143b4c4660637ba2a127 Mon Sep 17 00:00:00 2001 From: Segher Boessenkool Date: Mon, 18 Apr 2016 10:57:01 +0200 Subject: [PATCH] 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.
