# dev-lang/rust[system-llvm] guarantees a matching llvm-core/llvm:<slot> is
# installed (rust's own DEPEND pins that slot), which is required to merge
# PGO profiles with a compatible llvm-profdata. Bundled-LLVM rust builds and
# dev-lang/rust-bin ship no llvm-profdata at all, so pgo is unsupported there.
BDEPEND="pgo? ( dev-lang/rust[system-llvm] )"

# This test guards that the in-repo tree-sitter editor grammar
# (editors/tree-sitter-eventb, a git submodule absent from the release tarball)
# stays in sync with the canonical token tables. It checks files this package
# neither builds nor installs, so skip it rather than fetch the submodule.
# The fuzzer's grammar-derived tests read the same submodule but skip
# themselves when it is missing, so they need no entry here.
