2021-03-11cmd: move GOEXPERIMENT knob from make.bash to cmd/goMatthew Dempsky
This CL changes GOEXPERIMENT to act like other GO[CONFIG] environment variables. Namely, that it can be set at make.bash time to provide a default value used by the toolchain, but then can be manually set when running either cmd/go or the individual tools (compiler, assembler, linker). For example, it's now possible to test rsc.io/tmp/fieldtrack by simply running: GOEXPERIMENT=fieldtrack go test -gcflags=-l rsc.io/tmp/fieldtrack \ -ldflags=-k=rsc.io/tmp/fieldtrack.tracked without needing to re-run make.bash. (-gcflags=-l is needed because the compiler's inlining abilities have improved, so calling a function with a for loop is no longer sufficient to suppress inlining.) Fixes #42681.

2019-04-30all: add new GOOS=illumos, split out of GOOS=solarisJoshua M. Clulow
Like GOOS=android which implies the "linux" build tag, GOOS=illumos implies the "solaris" build tag. This lets the existing ecosystem of packages still work on illumos, but still permits packages to start differentiating between solaris and illumos.

This commit allows to cross-compiling aix/ppc64. The nosplit limit must twice as large as on others platforms because of AIX syscalls. The stack limit, especially stackGuardMultiplier, was set by cmd/dist during the bootstrap and doesn't depend on GOOS/GOARCH target.

2018-04-29runtime: iterate over set bits in adjustpointersJosh Bleecher Snyder
There are several things combined in this change. First, eliminate the gobitvector type in favor of adding a ptrbit method to bitvector. In non-performance-critical code, use that method. In performance critical code, though, load the bitvector data one byte at a time and iterate only over set bits. To support that, add and use sys.Ctz8. name old time/op new time/op delta StackCopyPtr-8 81.8ms ± 5% 78.9ms ± 3% -3.58% (p=0.000 n=97+96) StackCopy-8 65.9ms ± 3% 62.8ms ± 3% -4.67% (p=0.000 n=96+92) StackCopyNoCache-8 105ms ± 3% 102ms ± 3% -3.38% (p=0.000 n=96+95) Change-Id: I00b80f45612708bd440b1a411a57fa6dfa24aa74 Reviewed-on: https://go-review.googlesource.com/109716 Run-TryBot: Josh Bleecher Snyder <josharian@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Austin Clements <austin@google.com>
2018-04-11go/build, runtime/internal/sys: reserve RISC-V arch namesTobias Klauser
In #17528 it was discussed (off-topic to the actual issue) to reserve GOARCH names for the RISC-V architecture. With the first RISC-V Linux-capable development boards released (e.g. HiFive Unleashed), Linux distributions being ported to RISC-V (e.g. Debian, Fedora) and RISC-V support being added to gccgo (CL 96377), it becomes more likely that Go software (and maybe Go itself) will be ported as well. Add riscv and riscv64 (which is already used by gccgo), so Go 1.11 will already recognize "*_riscv{,64}.go" as reserved files.

This is the first commit of a series that will add WebAssembly as an architecture target. The design document can be found at https://docs.google.com/document/d/131vjr4DH6JFnb-blm_uRdaC0_Nv3OUwjEY5qVCxCup4. The GOARCH name "wasm" is the official abbreviation of WebAssembly. The GOOS name "js" got chosen because initially the host environment that executes WebAssembly bytecode will be web browsers and Node.js, which both use JavaScript to embed WebAssembly.

2018-01-09cmd/link: set runtime.GOROOT default during linkRuss Cox
Suppose you build the Go toolchain in directory A, move the whole thing to directory B, and then use it from B to build a new program hello.exe, and then run hello.exe, and hello.exe crashes with a stack trace into the standard library. Long ago, you'd have seen hello.exe print file names in the A directory tree, even though the files had moved to the B directory tree. About two years ago we changed the compiler to write down these files with the name "$GOROOT" (that literal string) instead of A, so that the final link from B could replace "$GOROOT" with B, so that hello.exe's crash would show the correct source file paths in the stack trace. (golang.org/cl/18200) Now suppose that you do the same thing but hello.exe doesn't crash: it prints fmt.Println(runtime.GOROOT()). And you run hello.exe after clearing $GOROOT from the environment. Long ago, you'd have seen hello.exe print A instead of B. Before this CL, you'd still see hello.exe print A instead of B. This case is the one instance where a moved toolchain still divulges its origin. Not anymore. After this CL, hello.exe will print B, because the linker sets runtime/internal/sys.DefaultGoroot with the effective GOROOT from link time. This makes the default result of runtime.GOROOT once again match the file names recorded in the binary, after two years of divergence. With that cleared up, we can reintroduce GOROOT into the link action ID and also reenable TestExecutableGOROOT/RelocatedExe. When $GOROOT_FINAL is set during link, it is used in preference to $GOROOT, as always, but it was easier to explain the behavior above without introducing that complication. Fixes #22155. Fixes #20284. Fixes #22475.
