Keith Randall 657c885fb9 cmd/compile: when combining stores, use line number of first store
var p *[2]uint32 = ...
p[0] = 0
p[1] = 0

When we combine these two 32-bit stores into a single 64-bit store,
use the line number of the first store, not the second one.
This differs from the default behavior because usually with the combining
that the compiler does, we use the line number of the last instruction
in the combo (e.g. load+add, we use the line number of the add).

This is the same behavior that gcc does in C (picking the line
number of the first of a set of combined stores).

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.

To run just these tests, execute:

../bin/go test cmd/internal/testdir

To run just tests from specified files in this directory, execute:

../bin/go test cmd/internal/testdir -run='Test/(file1.go|file2.go|...)'

Standard library tests should be written as regular Go tests in the appropriate package.

The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:

  • it is most naturally expressed using the test runner; or
  • it is also applicable to gccgo and other Go tool chains.
