Matthew Dempsky 6985ab27df cmd/compile: fix unified IR's pointer-shaping In CL 424734, I implemented pointer shaping for unified IR. Evidently though, we didn't have any test cases that check that uses of pointer-shaped expressions were handled correctly. In the reported test case, the struct field "children items[node[T]]" gets shaped to "children items[go.shape.uint8]" (underlying type "[]go.shape.uint8"); and so the expression "n.children[i]" has type "go.shape.uint8" and the ".items" field selection expression fails. The fix implemented in this CL is that any expression of derived type now gets an explicit "reshape" operation applied to it, to ensure it has the appropriate type for its context. E.g., the "n.children[i]" OINDEX expression above gets "reshaped" from "go.shape.uint8" to "node[go.shape.int]", allowing the field selection to succeed. This CL also adds a "-d=reshape" compiler debugging flag, because I anticipate debugging reshaping operations will be something to come up again in the future. Fixes #54535.

README.md

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.
