Make sure that if we encode an explicit base register, we print it. That will ensure that if we make an Addr with an auto variable but a base that isn't SP, then it will be obvious from the disassembly.

In an unrelated CL I found a way to increase the likelihood of latent flaky tests and found this one. This is just like yesterday's https://golang.org/cl/37624 and dozens before it (all remnants from the great net/http test parallelization of Nov 2016 in https://golang.org/cl/32684).

This adds the necessary changes so that atomics are treated as intrinsics on ppc64x. The implementations of And8 and Or8 require power8 for both ppc64 and ppc64le.

This makes a change in the SSA code generated for OpPPC64Xf2i64 and OpPPC64Xi2f64 to use register based instructions to convert between float and integer. This will require at least power8. Currently the conversion is done by storing to and loading from memory, which is more expensive.

The builtin runtime package definitions intentionally diverge from the actual runtime package's, but this only works as long as they never overlap. To make it easier to expand the builtin runtime package, this CL now loads their definitions into a logically separate "go.runtime" package. By resetting the package's Prefix field to "runtime", any references to builtin definitions will still resolve against the real package runtime. Fixes #14482. Passes toolstash -cmp.

Removes an extra function call for TrailingZeroes and thus may increase chances for inlining. Change-Id: Iefd8d4402dc89b64baf4e5c865eb3dadade623af Reviewed-on: https://go-review.googlesource.com/37613 Run-TryBot: Robert Griesemer <gri@golang.org> Reviewed-by:

Nobody intends to have duplicates anyway because it's so undefined and everything handles it so poorly. Removing duplicates automatically simplifies code and makes existing code do what people already expect.

The new Map implementation introduced in golang.org/cl/33201 did not differentiate if an invalid UTF-8 sequence was decoded or the RuneError rune. It would therefore always advance by 3 bytes (which is the length of the RuneError rune) instead of 1 for an invalid sequences. This cl adds a check to correctly determine the length of bytes needed to advance to the next rune. Fixes #19330.

There's no need to use @block rules, as canMergeLoad makes sure that the load and op are already in the same block. With no @block needed, we also don't need to set the type explicitly. It can just be inherited from the op being rewritten. Noticed while working on #19284.

During map growth, buckets are evacuated in two ways. When a value is altered, its containing bucket is evacuated. Also, an evacuation mark is maintained and advanced every time. Prior to this CL, the evacuation mark was always incremented, even if the next bucket to be evacuated had already been evacuated. This CL changes evacuation mark advancement to skip previously evacuated buckets. This has the effect of making map evacuation both more aggressive and more consistent. Aggressive map evacuation is good. While the map is growing, map accesses must check two buckets, which may be far apart in memory. Map growth also delays garbage collection. And if map evacuation is not aggressive enough, there is a risk that a populate-once read-many map may be stuck permanently in map growth. This CL does not eliminate that possibility, but it shrinks the window.
