Matthew Dempsky e6c973198d [dev.regabi] cmd/compile: stop mangling SelectorExpr.Sel for ODOTMETH
ODOTMETH is unique among SelectorExpr expressions, in that Sel gets
mangled so that it no longer has the original identifier that was
selected (e.g., just "Foo"), but instead the qualified symbol name for
the selected method (e.g., "pkg.Type.Foo"). This is rarely useful, and
instead results in a lot of compiler code needing to worry about
undoing this change.

This CL changes ODOTMETH to leave the original symbol in place. The
handful of code locations where the mangled symbol name is actually
wanted are updated to use ir.MethodExprName(n).Sym() or (equivalently)
ir.MethodExprName(n).Func.Sym() instead.

Historically, the compiler backend has mistakenly used types.Syms
where it should have used ir.Name/ir.Funcs. And this change in
particular may risk breaking something, as the SelectorExpr.Sel will
no longer point at a symbol that uniquely identifies the called
method. However, I expect CL 280294 (desugar OCALLMETH into OCALLFUNC)
to have substantially reduced this risk, as ODOTMETH expressions are
now replaced entirely earlier in the compiler.

Passes toolstash -cmp.

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 run run.go

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

../bin/go run run.go -- 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.
