- If any simulated cycle counts mismatch, report them and fail the job
- Keep "Elapsed" only in cppbuild
- Ignore "Elapsed" and "CPU" samples less than 30 seconds - too noisy
- Widen acceptable ranges on "Elapsed" and "Memory"
- Add badge legend
Add a script that prints the job matrix of cases to run with RTLMeter.
This enables running different sets based on parameters. It will run
everything on scheduled nightly runs, but only a subset on PRs (to reduce
time and variance due to short cases).
Also prints the job matrix in descending duration order, which
effectively makes GitHub actions schedule longest jobs first to reduce
total workflow latency.
Add jemalloc as an alternative malloc implementation for the Verilator
binary. When both tcmalloc and jemalloc are available, jemalloc is
preferred due to its better performance on RTLMeter.
The new --enable-jemalloc flag (default=check) mirrors the existing
--enable-tcmalloc behavior: auto-detected at configure time, supports
both static and dynamic linking, and is disabled when --enable-dev-asan
is active.
All code is built as C++ via CXX, but we still have some references to
CC. Trying to make sure we don't add plain C later by hiding the C
compiler. (So it's always enough to override CXX=... in configure)
Chores:
- Remove ci-ccache-maint. This has never been useful and is just cruft.
- Remove then unused CI_COMMIT
- Change job names so they come out nicer in the web views
- Make os-name input to reusable-build always explicit
Improvements:
- Have at most build-test job in progress per branch
- Cancel in-progress build-test jobs on PRs
- In forks (that is, not on 'verilator/verilator'), cancel any
in-progress build-test jobs on push to the branch
