# Wrapper for ad-hoc invocations of the W65816 cross-compiler toolchain.
# Applies the same memory/CPU caps as smokeTest.sh so a runaway backend
# bug (infinite combine, runaway inserter) can't OOM-kill the whole tmux
# scope and take Claude Code down with it.
#
# Usage:
#   scripts/safeCC.sh clang --target=w65816 -O2 -S foo.c -o foo.s
#   scripts/safeCC.sh llc -march=w65816 foo.ll -o foo.s
#
# The first arg is resolved against tools/llvm-mos-build/bin/ if it isn't
# already an absolute or relative path containing a slash.
