cmd/internal/obj/arm, runtime: delete old ARM softfloat code

2018-04-17T18:27:55Z

CL 106735 changed to the new softfloat support on GOARM=5. ARM assembly code that uses FP instructions not guarded on GOARM, if any, will break. The easiest way to fix is probably to use Go implementation on GOARM=5, like MOVB runtime·goarm(SB), R11 CMP $5, R11 BEQ arm5 ... FP instructions ...

runtime: restore arm assembly stubs for div/mod

2017-06-15T03:51:03Z

These are used by DIV[U] and MOD[U] assembly instructions. Add a test in the stdlib so we actually exercise linking to these routines. Update #19507 Change-Id: I0d8e19a53e3744abc0c661ea95486f94ec67585e Reviewed-on: https://go-review.googlesource.com/45703 Reviewed-by: Cherry Zhang

[dev.ssa] cmd/compile: add floating point optimizations in SSA for ARM

2016-07-16T03:13:22Z

Add some simplification rules for floating point ops. cmd/internal/obj/arm supports instructions that compare FP register to 0, but runtime softfloat simulator does not. This CL adds these instructions to softfloat simulator as well. Updates #15365.

cmd/compile: repair MININT conversion bug in arm softfloat

2016-05-05T22:29:25Z

Negative-case conversion code was wrong for minimum int32, used negate-then-widen instead of widen-then-negate. Test already exists; this fixes the failure. Fixes #15563.
