# gusty build & test targets.

#

# LLVM toolchain: LLVM 20. Opaque pointers are the default in LLVM 20, so

# llc-20 needs no -opaque-pointers flag.

# The suite is subprocess-bound: almost every case in pkg/lang ends inside llc-20, cc, lli-20 or

# python3, so running its cases one at a time leaves three of the runner's four cores idle (ADR 0313).

# `testshards` runs the same cases in one process per core. It is not a different test suite — the

# partition comes from `go test -list`, every case runs exactly once, and each case asserts what it

# always asserted.

#

# `make test` remains the plain serial command, and it is the one to use for the modes that write

# per-run artifacts (GUSTY_GOLDEN_UPDATE rewriting the drift ledger, GUSTY_GOLDEN_MISSING collecting

# sources the record does not cover): N shards would each write their own subset over the file.

#

# `test` runs with -count=1. Half the suite reads files outside its own package (docs/*.md, roadmap.md,

# integration/programs/*.gy) and those are not in `go test`'s cache key, so on a warm cache a doc edit can be

# certified by a run that never opened the file it changed — which is the opposite of what a guard is for.
