USE_COVERAGE instruments the build with clang's -fprofile-instr-generate
-fcoverage-mapping, exposed as the clang-coverage preset (build-coverage/,
inheriting clang-devel so the dev asserts stay on, Qt off since nothing in
the test path needs it).
The instrumentation is tree-wide rather than scoped to pcsx2/arm64: much of
the JIT is inline code living in headers that get pulled into core and common
translation units, so narrowing at build time would drop counters for exactly
the code we care about. tools/coverage.sh narrows at report time instead,
where the filter is exact.
The script builds the five gtest binaries, runs them with per-process profile
files, merges, and reports scoped to pcsx2/arm64/ (--scope all widens to the
other ARM64-only sources). Two hazards it defends against:
- cmake --preset takes the source dir from the working directory and ignores
-S, so running this through the /home/bmd/ARMSX2 symlink bakes the
symlinked path into every coverage mapping. It cds first.
- llvm-cov does not error when --sources matches nothing; it reports every
file it has data for, which reads as a plausible whole-tree number. The
filter prefix is read back from CMAKE_HOME_DIRECTORY so it always matches
what the compiler recorded, and a row-count tripwire fails the run if the
report escapes its scope anyway.
Baseline for pcsx2/arm64/: 74.65% lines, 79.94% functions, 77.70% regions.
