2018-03-19[PR81647][AARCH64] Fix handling of Unordered Comparisons in aarch64-simd.mdSudakshina Das4-44/+114
This patch fixes the inconsistent behavior observed at -O3 for the unordered comparisons. According to the online docs (https://gcc.gnu.org/onlinedocs /gcc-7.2.0/gccint/Unary-and-Binary-Expressions.html), all of the following should not raise an FP exception: - UNGE_EXPR - UNGT_EXPR - UNLE_EXPR - UNLT_EXPR - UNEQ_EXPR Also ORDERED_EXPR and UNORDERED_EXPR should only return zero or one. The aarch64-simd.md handling of these were generating exception raising instructions such as fcmgt. This patch changes the instructions that are emitted in order to not give out the exceptions. We first check each operand for NaNs and force any elements containing NaN to zero before using them in the compare. Example: UN<cc> (a, b) -> UNORDERED (a, b) | (cm<cc> (isnan (a) ? 0.0 : a, isnan (b) ? 0.0 : b)) The ORDERED_EXPR is now handled as (cmeq (a, a) & cmeq (b, b)) and UNORDERED_EXPR as ~ORDERED_EXPR and UNEQ as (~ORDERED_EXPR | cmeq (a,b)).

2018-03-16libgo: add runtime/pprof/internal/profile.gox to noinst_DATAIan Lance Taylor1-1/+1
Also add noinst_DATA to CHECK_DEPS; it's not needed in practice since `make` will build noinst_DATA, but it's logically required and will make a difference if any of the noinst_DATA sources change between `make` and `make check`. Tony Reix figured out why omitting packages from noinst_DATA didn't seem to matter: because if gccgo can't find foo.gox, it will fall back to reading the export data in foo.o, and foo.o will exist because these packages go into libgo.a.
