I'm not entirely sure why the JSON* numbers have changed, but
eyeballing the profile suggests that it could be spending less
and more time in runtime.{new,old}stack, so it could simply be
stack-split boundary noise.

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

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)
