cmd/internal/obj/mips: add support of LLV, SCV, NOOP instructions

2017-05-16T17:15:11+00:00

LLV and SCV are 64-bit load-linked and store-conditional. They
were used in runtime as #define WORD. Change them to normal
instruction form.

NOOP is hardware no-op. It was written as WORD $0. Make a name
for it for better disassembly output.

Fixes #12561.
Fixes #18238.

runtime/internal/atomic: Remove unnecessary checks for GOARCH_ppc64

2017-03-22T18:14:41+00:00

Starting in go1.9, the minimum processor requirement for ppc64 is POWER8. This
means the checks for GOARCH_ppc64 in asm_ppc64x.s can be removed, since we can
assume LBAR and STBCCC instructions (both from ISA 2.06) will always be
available.

Updates #19074

runtime/internal/atomic: crash on unaligned 64-bit ops on 32-bit MIPS

2016-11-22T02:05:07+00:00

This check was originally implemented by Vladimir in
https://go-review.googlesource.com/c/31489/1/src/runtime/internal/atomic/atomic_mipsx.go#30
but removed due to my comment (Sorry!). This CL adds it back.

Fixes #17786.

runtime/internal/atomic: add TestUnaligned64

2016-11-12T06:38:40+00:00

Add a variant of sync/atomic's TestUnaligned64 to
runtime/internal/atomic.

Skips the test on arm for now where it's currently failing.
