This new error is the only API change in the current draft of
Go 1.0.2 CLs. I'd like to include the CL that introduced it,
because it replaces a mysterious 'internal error' with a
useful error message, but I don't want any API changes,
so unexport the error constant for now. It can be
re-exported for Go 1.1.

cmd/5c, cmd/5g, cmd/5l: fix cross compilation failure on darwin · 072e36d5

Dave Cheney authored Jun 08, 2012

Fixes #3708.

The fix to allow 5{c,g,l} to compile under clang 3.1 broke cross
compilation on darwin using the Apple default compiler on 10.7.3.

This failure was introduced in 9b455eb64690.

This has been tested by cross compiling on darwin/amd64 to linux/arm using

* gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)
* clang version 3.1 (branches/release_31)

As well as on linux/arm using

* gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)
* Ubuntu clang version 3.0-6ubuntu3 (tags/RELEASE_30/final) (based on LLVM 3.0)
* Debian clang version 3.1-4 (branches/release_31) (based on LLVM 3.1)

cmd/gc: run escape analysis in call graph dependency order · 9fe42473

Russ Cox authored Jun 07, 2012

If there are mutually recursive functions, there is a cycle in
the dependency graph, so the order is actually dependency order
among the strongly connected components: mutually recursive
functions get put into the same batch and analyzed together.
(Until now the entire package was put in one batch.)

The non-recursive case (single function, maybe with some
closures inside) will be able to be more precise about inputs
that escape only back to outputs, but that is not implemented yet.

cmd/gc: fix type checking loop · 6363fc5a

Russ Cox authored Jun 07, 2012

CL 4313064 fixed its test case but did not address a
general enough problem:

type T1 struct { F *T2 }
type T2 T1
type T3 T2

could still end up copying the definition of T1 for T2
before T1 was done being evaluated, or T3 before T2
was done.

In order to propagate the updates correctly,
record a copy of an incomplete type for re-execution
once the type is completed. Roll back CL 4313064.

Fixes #3709.

test/bench/go1: add go/parser benchmark · 64236820

Dave Cheney authored Jun 07, 2012

As discussed in

https://groups.google.com/d/msg/golang-dev/Na9XE6mcQyY/zbeBI7R-vnoJ

Here is a static copy of the go/parser benchmark. I ended up using
fancy encodings because the original parser.go had a number of `s
scattered throughout which made it hard to embed the source directly.

Curiously on my laptop this benchmark always scores roughly 10% higher
than the standalone benchmark. This may be down to the generation of
the fasta data set triggering the cpu governor to raise the cpu speed.
However the benchmark is consistent with itself across multiple runs.
