      cmd/compile: intrinsify RotateLeft32 on wasm · b003afe4
      Brian Kessler authored
      wasm has 32-bit versions of all integer operations. This change
      lowers RotateLeft32 to i32.rotl on wasm and intrinsifies the math/bits
      call.  Benchmarking on amd64 under node.js this is ~25% faster.
      
      node v10.15.3/amd64
      name          old time/op  new time/op  delta
      RotateLeft    8.37ns ± 1%  8.28ns ± 0%   -1.05%  (p=0.029 n=4+4)
      RotateLeft8   11.9ns ± 1%  11.8ns ± 0%     ~     (p=0.167 n=5+5)
      RotateLeft16  11.8ns ± 0%  11.8ns ± 0%     ~     (all equal)
      RotateLeft32  11.9ns ± 1%   8.7ns ± 0%  -26.32%  (p=0.008 n=5+5)
      RotateLeft64  8.31ns ± 1%  8.43ns ± 2%     ~     (p=0.063 n=5+5)

      LE Manh Cuong authored
      .dynsym section info field is the index of first non-local symbol, mean
      the number of local symbols.
      
      The go linker have never ever set it before, so just set it.

      ld: ensure that PE versions sync for internal and external linkage · c96d794f
      Jason A. Donenfeld authored
      Previously users who opted into cgo might have received a bit of a
      behavior surprise when their mingw installation defaulted to a
      potentially older and different set of compatibility hacks. Since Go is
      explicitly targeting >=6.1 for internal linkage, propagate these changes
      to external linkage too.
      
      While we're at it, we move these values into constant variables so that
      they don't become out of sync and allow for easy updating as Go
      gradually drops compatibility for older operating systems.
