cmd/compile: apply constant folding to ORUNESTR

2019-09-26T23:54:29+00:00

ORUNESTR represents the special case of integer->string conversion. If
the integer is a constant, then the string is a constant too, so
evconst needs to perform constant folding here.

Passes toolstash-check.

Fixes #34563.

cmd/compile: fix compiler bug for constant equality comparison

2016-09-17T01:12:24+00:00

The compiler incorrectly will error when comparing a nil pointer
interface to a nil pointer of any other type. Example:
(*int)(nil) == interface{}(nil)
Will error with "gc: illegal constant expression: *int == interface {}"

Fixes #16702

cmd/compile: allow huge rsh in constants arithmetic

2015-08-21T20:27:22+00:00

Currently an expression like

var v = 0 >> 1000

is rejected by gc with a "stupid shift" error, while gotype
compiles it successfully.

As suggested by gri on the issue tracker, allow an rsh right
operand to be any valid uint value.

Fixes #11328

exp/ssa/interp: (#6 of 5): test interpretation of SSA form of $GOROOT/test/*.go.

2013-02-21T17:48:38+00:00

The interpreter's os.Exit now triggers a special panic rather
than kill the test process.  (It's semantically dubious, since
it will run deferred routines.)  Interpret now returns its
exit code rather than calling os.Exit.

Also:
- disabled parts of a few $GOROOT/tests via os.Getenv("GOSSAINTERP").
- remove unnecessary 'slots' param to external functions; they
  are never closures.

Most of the tests are disabled until go/types supports shifts.
They can be reenabled if you patch this workaround:

test: [a-c]: add introductory comments to tests

2012-02-19T02:19:43+00:00

Very few of the compiler regression tests include a comment
saying waht they do. Many are obvious, some are anything but.
I've started with a-c in the top directory. More will follow once
we agree on the approach, correctness, and thoroughness here.
zerodivide.go sneaked in too.
