2017-05-19rs6000: Make constant formation a tiny bit betterSegher Boessenkool2-0/+7
If we cannot load a constant into a register in one insn, and that constant is a valid mask (for rotate instructions), we currently prefer to load -1 and then mask it. This patch makes us not do that if instead we could use two add or or instructions, since those are sometimes faster on certain CPUs (and never are slower). * config/rs6000/rs6000.md (splitter to load of -1 and mask): Don't use this splitter if two add or or instructions would also work for the constant we want to generate.

2017-05-17Fix comparison of decimal float zeroes (PR80692)Segher Boessenkool4-3/+27
Decimal float negative zero should compare equal to positive zero. Decimal float zeroes are encoded as value class "normal" (in real.c); they need to be handled specially, but in this one case that does not yet happen. This fixes it. PR middle-end/80692 * real.c (do_compare): Give decimal_do_compare preference over comparing just the signs. gcc/testsuite/ PR middle-end/80692 * gcc.c-torture/execute/pr80692.c: New testcase.

2017-05-17libgo: add "vendor" to pkgpath for vendored standard packagesIan Lance Taylor1-1/+1
Ensure that the packages vendored into the standard library do not have the same pkgpath as the actual packages. If we don't, attempts to build and test the actual packages will get confused. The specific error I was seeing was import loops, causing some of the packages to fail to get initialized, causing an obscure run time crash.
