This is the first in a series of CLs to replace the use of pointers in binary read-only data with offsets. In standard Go binaries these CLs have a small effect, shrinking 8-byte pointers to 4-bytes. In position-independent code, it also saves the dynamic relocation for the pointer. This has a significant effect on the binary size when building as PIE, c-archive, or c-shared. darwin/amd64: cmd/go: -12KB (0.1%) jujud: -82KB (0.1%) linux/amd64 PIE: cmd/go: -86KB (0.7%) jujud: -569KB (0.7%) For #6853.

In the event of a partial write on Solaris and some BSDs, the offset pointer passed to sendfile() will be updated even though the function returns -1 if errno is set to EAGAIN/EINTR. In that case, calculate the bytes written based on the difference between the updated offset and the original offset. If no bytes were written, and errno is set to EAGAIN/EINTR, ignore the errno.

It seems cleaner and more consistent with other files to list the architectures that have assembly implementations rather than to list those that do not. This means we don't have to add s390x and future platforms to this list. Change-Id: I2ad3f66b76eb1711333c910236ca7f5151b698e5 Reviewed-on: https://go-review.googlesource.com/21770Reviewed-by:

Most architectures can only generate nil checks when the the address to check is in a register. Currently only amd64 and 386 can generate checks for addresses that reside in memory. This is unlikely to change so the architecture check has been inverted. Change-Id: I73697488a183406c79a9039c62823712b510bb6a Reviewed-on: https://go-review.googlesource.com/21861Reviewed-by:

We need to make sure that when we combine loads, we only do so if there are no other uses of the load. We can't split one load into two because that can then lead to inconsistent loaded values in the presence of races. Add some aggressive copy removal code so that phantom "dead copy" uses of values are cleaned up promptly. This lets us use x.Uses==1 conditions reliably.

s390x does not require duffzero/duffcopy since it has storage-to-storage instructions that can copy/clear up to 256 bytes at a time. peep contains several new passes to optimize instruction sequences that match s390x instructions such as the compare-and-branch and load/store multiple instructions. copyprop and subprop have been extended to work with moves that require sign/zero extension. This work could be ported to other architectures that do not used sized math however it does add complexity and will probably be rendered unnecessary by ssa in the near future.

Apply golang/tools@5804fef4c0556d3e5e7d2440740a3d7aced7d58b. In the context of cmd/go build tool, import path is a '/'-separated path. This can be inferred from `go help importpath` and `go help packages`. vcsFromDir documentation says on return, root is the import path corresponding to the root of the repository. On Windows and other OSes where os.PathSeparator is not '/', that wasn't true since root would contain characters other than '/', and therefore it wasn't a valid import path corresponding to the root of the repository. Fix that by using filepath.ToSlash. Add test coverage for vcsFromDir, it was previously not tested. It's taken from golang.org/x/tools/go/vcs tests, and modified to improve style. Additionally, remove an unneccessary statement from the documentation "(thus root is a prefix of importPath)". There is no variable importPath that is being referred to (it's possible p.ImportPath was being referred to). Without it, the description of root value matches the documentation of repoRoot.root struct field: // root is the import path corresponding to the root of the // repository root string Rename and change signature of vcsForDir(p *Package) to vcsFromDir(dir, srcRoot string). This is more in sync with the x/tools version. It's also simpler, since vcsFromDir only needs those two values from Package, and nothing more. Change "for" to "from" in name because it's more consistent and clear. Update usage of vcsFromDir to match the new signature, and respect that returned root is a '/'-separated path rather than a os.PathSeparator separated path. Fixes #15040. Updates #7723. Helps #11490.

Per RFC 5246, 7.4.1.3: cipher_suite The single cipher suite selected by the server from the list in ClientHello.cipher_suites. For resumed sessions, this field is the value from the state of the session being resumed. The specifications are not very clearly written about resuming sessions at the wrong version (i.e. is the TLS 1.0 notion of "session" the same type as the TLS 1.1 notion of "session"?). But every other implementation enforces this check and not doing so has some odd semantics.

Updates #14921 Fixes #14969 Sample code: var x []byte func p() { x = append(x, 1, 2, 3) } Before: "".p t=1 size=224 args=0x0 locals=0x48 0x0000 00000 (append.go:21) TEXT "".p(SB), $72-0 0x0000 00000 (append.go:21) MOVQ (TLS), CX 0x0009 00009 (append.go:21) CMPQ SP, 16(CX) 0x000d 00013 (append.go:21) JLS 199 0x0013 00019 (append.go:21) SUBQ $72, SP 0x0017 00023 (append.go:21) FUNCDATA $0, gclocals·33cdeccccebe80329f1fdbee7f5874cb(SB) 0x0017 00023 (append.go:21) FUNCDATA $1, gclocals·33cdeccccebe80329f1fdbee7f5874cb(SB) 0x0017 00023 (append.go:19) MOVQ "".x+16(SB), CX 0x001e 00030 (append.go:19) MOVQ "".x(SB), DX 0x0025 00037 (append.go:19) MOVQ "".x+8(SB), BX 0x002c 00044 (append.go:19) MOVQ BX, "".autotmp_0+64(SP) 0x0031 00049 (append.go:22) LEAQ 3(BX), BP 0x0035 00053 (append.go:22) CMPQ BP, CX 0x0038 00056 (append.go:22) JGT $0, 131 0x003a 00058 (append.go:22) MOVB $1, (DX)(BX*1) 0x003e 00062 (append.go:22) MOVB $2, 1(DX)(BX*1) 0x0043 00067 (append.go:22) MOVB $3, 2(DX)(BX*1) 0x0048 00072 (append.go:22) MOVQ BP, "".x+8(SB) 0x004f 00079 (append.go:22) MOVQ CX, "".x+16(SB) 0x0056 00086 (append.go:22) MOVL runtime.writeBarrier(SB), AX 0x005c 00092 (append.go:22) TESTB AL, AL 0x005e 00094 (append.go:22) JNE $0, 108 0x0060 00096 (append.go:22) MOVQ DX, "".x(SB) 0x0067 00103 (append.go:23) ADDQ $72, SP 0x006b 00107 (append.go:23) RET 0x006c 00108 (append.go:22) LEAQ "".x(SB), CX 0x0073 00115 (append.go:22) MOVQ CX, (SP) 0x0077 00119 (append.go:22) MOVQ DX, 8(SP) 0x007c 00124 (append.go:22) PCDATA $0, $0 0x007c 00124 (append.go:22) CALL runtime.writebarrierptr(SB) 0x0081 00129 (append.go:23) JMP 103 0x0083 00131 (append.go:22) LEAQ type.[]uint8(SB), AX 0x008a 00138 (append.go:22) MOVQ AX, (SP) 0x008e 00142 (append.go:22) MOVQ DX, 8(SP) 0x0093 00147 (append.go:22) MOVQ BX, 16(SP) 0x0098 00152 (append.go:22) MOVQ CX, 24(SP) 0x009d 00157 (append.go:22) MOVQ BP, 32(SP) 0x00a2 00162 (append.go:22) PCDATA $0, $0 0x00a2 00162 (append.go:22) CALL runtime.growslice(SB) 0x00a7 00167 (append.go:22) MOVQ 40(SP), DX 0x00ac 00172 (append.go:22) MOVQ 48(SP), AX 0x00b1 00177 (append.go:22) MOVQ 56(SP), CX 0x00b6 00182 (append.go:22) ADDQ $3, AX 0x00ba 00186 (append.go:19) MOVQ "".autotmp_0+64(SP), BX 0x00bf 00191 (append.go:22) MOVQ AX, BP 0x00c2 00194 (append.go:22) JMP 58 0x00c7 00199 (append.go:22) NOP 0x00c7 00199 (append.go:21) CALL runtime.morestack_noctxt(SB) 0x00cc 00204 (append.go:21) JMP 0 After: "".p t=1 size=208 args=0x0 locals=0x48 0x0000 00000 (append.go:21) TEXT "".p(SB), $72-0 0x0000 00000 (append.go:21) MOVQ (TLS), CX 0x0009 00009 (append.go:21) CMPQ SP, 16(CX) 0x000d 00013 (append.go:21) JLS 191 0x0013 00019 (append.go:21) SUBQ $72, SP 0x0017 00023 (append.go:21) FUNCDATA $0, gclocals·33cdeccccebe80329f1fdbee7f5874cb(SB) 0x0017 00023 (append.go:21) FUNCDATA $1, gclocals·33cdeccccebe80329f1fdbee7f5874cb(SB) 0x0017 00023 (append.go:19) MOVQ "".x+16(SB), CX 0x001e 00030 (append.go:19) MOVQ "".x+8(SB), DX 0x0025 00037 (append.go:19) MOVQ DX, "".autotmp_0+64(SP) 0x002a 00042 (append.go:19) MOVQ "".x(SB), BX 0x0031 00049 (append.go:22) LEAQ 3(DX), BP 0x0035 00053 (append.go:22) MOVQ BP, "".x+8(SB) 0x003c 00060 (append.go:22) CMPQ BP, CX 0x003f 00063 (append.go:22) JGT $0, 84 0x0041 00065 (append.go:22) MOVB $1, (BX)(DX*1) 0x0045 00069 (append.go:22) MOVB $2, 1(BX)(DX*1) 0x004a 00074 (append.go:22) MOVB $3, 2(BX)(DX*1) 0x004f 00079 (append.go:23) ADDQ $72, SP 0x0053 00083 (append.go:23) RET 0x0054 00084 (append.go:22) LEAQ type.[]uint8(SB), AX 0x005b 00091 (append.go:22) MOVQ AX, (SP) 0x005f 00095 (append.go:22) MOVQ BX, 8(SP) 0x0064 00100 (append.go:22) MOVQ DX, 16(SP) 0x0069 00105 (append.go:22) MOVQ CX, 24(SP) 0x006e 00110 (append.go:22) MOVQ BP, 32(SP) 0x0073 00115 (append.go:22) PCDATA $0, $0 0x0073 00115 (append.go:22) CALL runtime.growslice(SB) 0x0078 00120 (append.go:22) MOVQ 40(SP), CX 0x007d 00125 (append.go:22) MOVQ 56(SP), AX 0x0082 00130 (append.go:22) MOVQ AX, "".x+16(SB) 0x0089 00137 (append.go:22) MOVL runtime.writeBarrier(SB), AX 0x008f 00143 (append.go:22) TESTB AL, AL 0x0091 00145 (append.go:22) JNE $0, 168 0x0093 00147 (append.go:22) MOVQ CX, "".x(SB) 0x009a 00154 (append.go:22) MOVQ "".x(SB), BX 0x00a1 00161 (append.go:19) MOVQ "".autotmp_0+64(SP), DX 0x00a6 00166 (append.go:22) JMP 65 0x00a8 00168 (append.go:22) LEAQ "".x(SB), DX 0x00af 00175 (append.go:22) MOVQ DX, (SP) 0x00b3 00179 (append.go:22) MOVQ CX, 8(SP) 0x00b8 00184 (append.go:22) PCDATA $0, $0 0x00b8 00184 (append.go:22) CALL runtime.writebarrierptr(SB) 0x00bd 00189 (append.go:22) JMP 154 0x00bf 00191 (append.go:22) NOP 0x00bf 00191 (append.go:21) CALL runtime.morestack_noctxt(SB) 0x00c4 00196 (append.go:21) JMP 0 Change-Id: I77a41ad3a22557a4bb4654de7d6d24a029efe34a Reviewed-on: https://go-review.googlesource.com/21813 Run-TryBot: Josh Bleecher Snyder <josharian@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: -

This is controlled by the "regalloc" stats flag, since regalloc calls stackalloc. The plan is for this to allow comparison of cheaper stack allocation algorithms with what we have now.

The decomposer of builtin types is confused by having structs still around from the user-type decomposer. They're all dead though, so just enabling a deadcode pass fixes things.
