Subject: [PATCH 0/5] gdb.perf/: Add JIT performance test
Date: Thu, 26 May 2022 00:37:06 +0200 [thread overview]
Message-ID: <20220525223711.845475-1-iii@linux.ibm.com> (raw)
Hi,
This series implements a JIT performance test as discussed in [1].
Patch 1 is a small fix, patches 2-4 are preparations and patch 5 is
the test itself.
The test can be used as follows:
$ make build-perf -j"$(nproc)" RUNTESTFLAGS=jit.exp
$ make check-perf RUNTESTFLAGS=jit-check.exp GDB_PERFTEST_MODE=run
The results can be converted to gnuplot-friendly format as follows:
$ perl -ne 'if (/:register_times:(\d+) (.+)/) { print "$1 $2\n"; }' \
<gdb.perf/outputs/jit/pieces/perftest.sum >jit.txt
I've uploaded the results to [2]. They are somewhat different from
those from Andrew, but they still show that [1] is an improvement.
The third result shown on the chart is from [3] - with it I can
pass the 10k JITed objects mark and finally debug CoreCLR JIT with
GDB. It's still WIP though - the testsuite shows a couple of
failures.
Best regards,
Ilya
