David Chase d8f60eea64 cmd/compile: enhance induction variable detection for unrolled loops Would suggest extending capabilities (32-bit, unsigned, etc) in separate CLs because prove bugs are so mystifying. This implements the suggestion in this comment https://go-review.googlesource.com/c/go/+/104041/10/src/cmd/compile/internal/ssa/loopbce.go#164 for inferring properly bounded iteration for loops of the form for i := K0; i < KNN-(K-1); i += K for i := K0; i <= KNN-K; i += K Where KNN is "known non negative" (i.e., len or cap) and K is also not negative. Because i <= KNN-K, i+K <= KNN and no overflow occurs. Also handles decreasing case (K1 > 0) for i := KNN; i >= K0; i -= K1 which works when MININT+K1 < K0 (i.e. MININT < K0-K1, no overflow) Signed only, also only 64 bit for now.

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

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.
