This commit adds two new functions to cgen.go: hasHMUL64 and hasRROTC64. These are used to determine whether or not an architecture supports the instructions needed to perform an optimization in cgen_div. This commit should not affect existing architectures (although it does add s390x to the new functions). However, since most architectures support HMUL the hasHMUL64 function could be modified to enable most of the optimizations in cgen_div on those platforms.

After mdempsky's recent changes, these are the only references to "TheChar" left in the Go tree. Without the context, and without knowing the history, this is confusing. Also rename sys.TheGoos and sys.TheGoarch to sys.GOOS and sys.GOARCH. Also change the heap dump format to include sys.GOARCH rather than TheChar, which is no longer a concept.

Instead of being a hint, resultInArg0 is now enforced by regalloc. This allows us to delete all the code from amd64/ssa.go which deals with converting from a semantically three-address instruction into some copies plus a two-address instruction.

Instead of spilling newlen, recalculate it. This removes a spill from the fast path, at the cost of a cheap recalculation on the (rare) growth path. This uses 8 bytes less of stack space. It generates two more bytes of code, but that is due to suboptimal register allocation; see far below. Runtime append microbenchmarks are all over the map, presumably due to incidental code movement. Sample code: func s(b []byte) []byte { b = append(b, 1, 2, 3) return b } Before: "".s t=1 size=160 args=0x30 locals=0x48 0x0000 00000 (append.go:8) TEXT "".s(SB), $72-48 0x0000 00000 (append.go:8) MOVQ (TLS), CX 0x0009 00009 (append.go:8) CMPQ SP, 16(CX) 0x000d 00013 (append.go:8) JLS 149 0x0013 00019 (append.go:8) SUBQ $72, SP 0x0017 00023 (append.go:8) FUNCDATA $0, gclocals·6432f8c6a0d23fa7bee6c5d96f21a92a(SB) 0x0017 00023 (append.go:8) FUNCDATA $1, gclocals·33cdeccccebe80329f1fdbee7f5874cb(SB) 0x0017 00023 (append.go:9) MOVQ "".b+88(FP), CX 0x001c 00028 (append.go:9) LEAQ 3(CX), DX 0x0020 00032 (append.go:9) MOVQ DX, "".autotmp_0+64(SP) 0x0025 00037 (append.go:9) MOVQ "".b+96(FP), BX 0x002a 00042 (append.go:9) CMPQ DX, BX 0x002d 00045 (append.go:9) JGT $0, 86 0x002f 00047 (append.go:8) MOVQ "".b+80(FP), AX 0x0034 00052 (append.go:9) MOVB $1, (AX)(CX*1) 0x0038 00056 (append.go:9) MOVB $2, 1(AX)(CX*1) 0x003d 00061 (append.go:9) MOVB $3, 2(AX)(CX*1) 0x0042 00066 (append.go:10) MOVQ AX, "".~r1+104(FP) 0x0047 00071 (append.go:10) MOVQ DX, "".~r1+112(FP) 0x004c 00076 (append.go:10) MOVQ BX, "".~r1+120(FP) 0x0051 00081 (append.go:10) ADDQ $72, SP 0x0055 00085 (append.go:10) RET 0x0056 00086 (append.go:9) LEAQ type.[]uint8(SB), AX 0x005d 00093 (append.go:9) MOVQ AX, (SP) 0x0061 00097 (append.go:9) MOVQ "".b+80(FP), BP 0x0066 00102 (append.go:9) MOVQ BP, 8(SP) 0x006b 00107 (append.go:9) MOVQ CX, 16(SP) 0x0070 00112 (append.go:9) MOVQ BX, 24(SP) 0x0075 00117 (append.go:9) MOVQ DX, 32(SP) 0x007a 00122 (append.go:9) PCDATA $0, $0 0x007a 00122 (append.go:9) CALL runtime.growslice(SB) 0x007f 00127 (append.go:9) MOVQ 40(SP), AX 0x0084 00132 (append.go:9) MOVQ 56(SP), BX 0x0089 00137 (append.go:8) MOVQ "".b+88(FP), CX 0x008e 00142 (append.go:9) MOVQ "".autotmp_0+64(SP), DX 0x0093 00147 (append.go:9) JMP 52 0x0095 00149 (append.go:9) NOP 0x0095 00149 (append.go:8) CALL runtime.morestack_noctxt(SB) 0x009a 00154 (append.go:8) JMP 0 After: "".s t=1 size=176 args=0x30 locals=0x40 0x0000 00000 (append.go:8) TEXT "".s(SB), $64-48 0x0000 00000 (append.go:8) MOVQ (TLS), CX 0x0009 00009 (append.go:8) CMPQ SP, 16(CX) 0x000d 00013 (append.go:8) JLS 151 0x0013 00019 (append.go:8) SUBQ $64, SP 0x0017 00023 (append.go:8) FUNCDATA $0, gclocals·6432f8c6a0d23fa7bee6c5d96f21a92a(SB) 0x0017 00023 (append.go:8) FUNCDATA $1, gclocals·33cdeccccebe80329f1fdbee7f5874cb(SB) 0x0017 00023 (append.go:9) MOVQ "".b+80(FP), CX 0x001c 00028 (append.go:9) LEAQ 3(CX), DX 0x0020 00032 (append.go:9) MOVQ "".b+88(FP), BX 0x0025 00037 (append.go:9) CMPQ DX, BX 0x0028 00040 (append.go:9) JGT $0, 81 0x002a 00042 (append.go:8) MOVQ "".b+72(FP), AX 0x002f 00047 (append.go:9) MOVB $1, (AX)(CX*1) 0x0033 00051 (append.go:9) MOVB $2, 1(AX)(CX*1) 0x0038 00056 (append.go:9) MOVB $3, 2(AX)(CX*1) 0x003d 00061 (append.go:10) MOVQ AX, "".~r1+96(FP) 0x0042 00066 (append.go:10) MOVQ DX, "".~r1+104(FP) 0x0047 00071 (append.go:10) MOVQ BX, "".~r1+112(FP) 0x004c 00076 (append.go:10) ADDQ $64, SP 0x0050 00080 (append.go:10) RET 0x0051 00081 (append.go:9) LEAQ type.[]uint8(SB), AX 0x0058 00088 (append.go:9) MOVQ AX, (SP) 0x005c 00092 (append.go:9) MOVQ "".b+72(FP), BP 0x0061 00097 (append.go:9) MOVQ BP, 8(SP) 0x0066 00102 (append.go:9) MOVQ CX, 16(SP) 0x006b 00107 (append.go:9) MOVQ BX, 24(SP) 0x0070 00112 (append.go:9) MOVQ DX, 32(SP) 0x0075 00117 (append.go:9) PCDATA $0, $0 0x0075 00117 (append.go:9) CALL runtime.growslice(SB) 0x007a 00122 (append.go:9) MOVQ 40(SP), AX 0x007f 00127 (append.go:9) MOVQ 48(SP), CX 0x0084 00132 (append.go:9) MOVQ 56(SP), BX 0x0089 00137 (append.go:9) ADDQ $3, CX 0x008d 00141 (append.go:9) MOVQ CX, DX 0x0090 00144 (append.go:8) MOVQ "".b+80(FP), CX 0x0095 00149 (append.go:9) JMP 47 0x0097 00151 (append.go:9) NOP 0x0097 00151 (append.go:8) CALL runtime.morestack_noctxt(SB) 0x009c 00156 (append.go:8) JMP 0 Observe that in the following sequence, we should use DX directly instead of using CX as a temporary register, which would make the new code a strict improvement on the old: 0x007f 00127 (append.go:9) MOVQ 48(SP), CX 0x0084 00132 (append.go:9) MOVQ 56(SP), BX 0x0089 00137 (append.go:9) ADDQ $3, CX 0x008d 00141 (append.go:9) MOVQ CX, DX 0x0090 00144 (append.go:8) MOVQ "".b+80(FP), CX Change-Id: I4ee50b18fa53865901d2d7f86c2cbb54c6fa6924 Reviewed-on: https://go-review.googlesource.com/21812 Run-TryBot: Josh Bleecher Snyder <josharian@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:Keith Randall <khr@golang.org>

This improves the short version of the writer test. First of all, it has a much quicker setup. Previously that could take up towards 0.5 second. Secondly, it will test all compression levels in short mode as well. Execution time is 1.7s/0.03s for normal/short mode.

This reverts commit ab4c9298. Sysmon critically depends on system timer resolution for retaking of Ps blocked in system calls. See #14790 for an example of a program where execution time goes from 2ms to 30ms if timeBeginPeriod(1) is not used. We can remove timeBeginPeriod(1) when we support UMS (#7876).

Generated with honnef.co/go/unused There is a large amount of unused code in cmd/internal/obj/s390x but that can wait til the s390x port is merged. There is some unused code in cmd/internal/unvendor/golang.org/x/arch/arm/armasm but that should be addressed upstream and a new revision imported.

Be more careful about inserting instrumentation in racewalk. If the node being instrumented is an OAS, and it has a non- empty Ninit, then append instrumentation to the Ninit list rather than letting it be inserted before the OAS (and the compilation of its init list). This deals with the case that the Ninit list defines a variable used in the RHS of the OAS. Fixes #15091.
