cmd/{5,6,8}g: reduce size of Prog and Addr · b2797f2a

Dave Cheney authored Dec 14, 2012

5g: Prog went from 128 bytes to 88 bytes
6g: Prog went from 174 bytes to 144 bytes
8g: Prog went from 124 bytes to 92 bytes

There may be a little more that can be squeezed out of Addr, but alignment will be a factor.

All: remove the unused pun field from Addr

log/syslog: fix flakey test on slow hosts · ae12e963

Dave Cheney authored Dec 13, 2012

Fixes #4467.

The syslog tests can fail if the timeout fires before the data arrives at the mock server. Moving the timeout onto the goroutine that is calling ReadFrom() and always processing the data returned before handling the error should improve the reliability of the test.

spec: calling delete on a nil map is a no-op · a9a49fe9

This is language change. It is a backward-compatible
change but for code that relies on a run-time panic
when calling delete on a nil map (unlikely).

cmd/6g, cmd/8g: simplify integer division code. · a617d062

Change suggested by iant. The compiler generates
special code for a/b when a is -0x80...0 and b = -1.
A single instruction can cover the case where b is -1,
so only one comparison is needed.
