cmd/compile: improve single blank variable handling in walkrange · 137e4a6c

Martin Möhrmann authored Sep 03, 2017

Refactor walkrange to treat "for _ = range a" as "for range a".

This avoids generating some later discarded nodes in the compiler.

Passes toolstash -cmp.

net/http: allow reuse of http.Request objects · 78c4dc37

Luan Santos authored Sep 11, 2017

Calling response.Body.Close() early would generarate a race before this.
Since closing would return early before the main code path had a chance
to reset the request canceler. Having a non-nil request canceler at the
start of the next request would cause a "request canceled" error.

Here we simply wait for the eofc channel to be closed before returning
from earlyCloseFn, ensuring that the caller won't be re-using that
Request object before we have a chance to reset the request canceler to
nil.

Fixes #21838

crypto/sha1: speed up sha1 for very small blocks · dc3b8a19

cmd/compile, math/bits: add rotate rules to PPC64.rules · fa3fe2e3

Lynn Boger authored Aug 29, 2017

This adds rules to match the code in math/bits RotateLeft,
RotateLeft32, and RotateLef64 to allow them to be inlined.

The rules are complicated because the code in these function
use different types, and the non-const version of these
shifts generate Mask and Carry instructions that become
subexpressions during the match process.

Also adds a testcase to asm_test.go.

Improvement in math/bits:

BenchmarkRotateLeft-16       1.57     1.32      -15.92%
BenchmarkRotateLeft32-16     1.60     1.37      -14.37%

crypto/elliptic: fix incomplete addition used in CombinedMult. · 2d69e9e2

Adam Langley authored May 04, 2017

The optimised P-256 includes a CombinedMult function, which doesn't do
dual-scalar multiplication, but does avoid an affine conversion for
ECDSA verification.

However, it currently uses an assembly point addition function that
doesn't handle exceptional cases.

Fixes #20215.

cmd/compile: request r12 for indirect calls on ppc64le · b74b43de

Lynn Boger authored Sep 11, 2017

On ppc64le, functions compiled with -shared expect r12 to
hold the function's address for indirect calls. Previously
this was enforced by generating a move instruction if the
address wasn't already in r12. This change avoids that extra
move by requesting r12 in the CALL ops that do indirect calls.

As a result of adding support for plugins on ppc64le, it was
discovered that there would be more cases where this extra
move was needed, so this seemed like a better solution.

cmd/compile: preserve escape information for map literals · 09812610

Martin Möhrmann authored Sep 10, 2017

While some map literals were marked non-escaping that information
was lost when creating the corresponding OMAKE node which made map
literals always heap allocated.

Copying the escape information to the corresponding OMAKE node allows
stack allocation of hmap and a map bucket for non escaping map literals.

cmd/link: don't generate runtime.text twice for buildmode=plugin on darwin · f797e485

https://golang.org/cl/29394 changed to include runtime.text and
runtime.etext in ctxt.Textp as a work around.
But it seems that the CL forgot to change genasmsym.
As a result, we are generating runtime.text and runtime.etext twice.

Set it when building plugins to ensure the -shared packages built for it

Hiroshi Ioka authored Sep 04, 2017

1. remove broken verification
   The runtime check assumes that no-pcln symbol entry have zero value,
   but the linker emit no entries if the symbol is no-pcln.
   As a result, if there are no-pcln symbols at the very end of pcln
   table, it will panic.
2. correct condition of export
   Handle special chracters in pluginpath correcty.
   Export "go.itab.*", so different plugins can share the same itab.

math: fix Abs, Copysign and Signbit benchmarks · ffb4708d

CL 62250 makes constant folding a bit more aggressive and these
benchmarks were optimized away. This CL adds some indirection to
the function arguments to stop them being folded.

The Copysign benchmark is a bit faster because I've left one
argument as a constant and it can be partially folded.
