cmd/cc, cmd/gc: update compilers, assemblers for liblink changes · 870e821d

Russ Cox authored Dec 16, 2013

- add buffered stdout to all tools and provide to link ctxt.
- avoid extra \n before ! in .6 files written by assemblers
  (makes them match the C compilers).
- use linkwriteobj instead of linkouthist+linkwritefuncs.
- in assemblers and C compilers, record pc explicitly in Prog,
  for use by liblink.
- in C compilers, preserve jump target links.
- in Go compilers (gsubr.c) attach gotype directly to
  corresponding LSym* instead of rederiving from instruction stream.
- in Go compilers, emit just one definition for runtime.zerovalue
  from each compilation.

This CL consists entirely of small adjustments.
The heavy lifting is in CL 39680043.
Each depends on the other.

unicode/utf16: add explicit test for decoding invalid runes. · 62baae6e

Dave Cheney authored Dec 16, 2013

The EncodeRune test exercises DecodeRune, but only for runes that it can encode. Add an explicit test for invalid utf16 surrogate pairs.

Bonus: coverage is now 100%

crypto/tls: generate random serial numbers. · 1dabd716

Adam Langley authored Dec 15, 2013

NSS (used in Firefox and Chrome) won't accept two certificates with the same
issuer and serial. But this causes problems with self-signed certificates
with a fixed serial number.

This change randomises the serial numbers in the certificates generated by
generate_cert.go.

crypto/cipher: fix CFB mode. · 1d546005

Adam Langley authored Dec 15, 2013

a073d65e6f8c had a couple of bugs in the CFB mode that I missed in code review:
        1) The loop condition wasn't updated from the old version.
        2) It wasn't safe when src and dst aliased.

Fixes #6950.

crypto/sha1: Optimise FUNC1 with alternate formulation · 107d1829

Nick Craig-Wood authored Dec 12, 2013

According to Wikipedia: http://en.wikipedia.org/wiki/SHA-1
there is an alternate formulation for the FUNC1 transform,
namely

f1 = d xor (b and (c xor d))

instead of

f1 = (b and c) or ((not b) and d)

This reduces the instruction count of FUNC1 from 6 to 4 and
makes about 5% speed improvement on amd64 and suprisingly 17%
on 386.
