Commits: 35d83d03 by Carl Friedrich Bolz-Tereick at 2020-02-16T15:26:19+01:00 redo 8fcba04d307f: don't generate tons and tons of guard_not_invalidated while tracing one benchmark had 43% of all guards be guard_not_invalidated However, this needs an adaptation in the optimizer, to remove guard_not_invalidated less aggressively: we need one guard_not_invalidated after every call that can invalidate something. This is independent to whether the quasiimmut_field op is removed or not! The tracer will only trace one guard_not_invalidated after each call, so even if the first quasiimmut_field is removed, the second one might not be and could rely on the presence of an earlier guard_not_invalidated. This might under rare circumstances leave a extra guard_not_invalidated in the trace! But guard_not_invalidated is cheap, it emits no instructions and its only cost is the size of the resume data. Therfore that is still a better tradeoff than capturing resume data for every quasiimmut_field in the front end *all the time* --HG-- branch : warmup-improvements-various - - - - - fe90f2f7 by Carl Friedrich Bolz-Tereick at 2020-02-16T15:31:21+01:00 this didn't quite work in practice, explicitly don't check the stack depth --HG-- branch : warmup-improvements-various - - - - - 12365ef7 by Carl Friedrich Bolz-Tereick at 2020-02-16T16:01:02+01:00 avoid the "ping pong" of the return value on the stack in the most common cases --HG-- branch : warmup-improvements-various - - - - - cbbdf5d5 by Carl Friedrich Bolz-Tereick at 2020-02-16T22:58:58+01:00 fix test --HG-- branch : warmup-improvements-various - - - - - ab78084a by Carl Friedrich Bolz-Tereick at 2020-02-16T23:06:40+01:00 cache result of call_loopinvariant in the heapcache --HG-- branch : warmup-improvements-various - - - - - 7bb0b5d9 by Carl Friedrich Bolz-Tereick at 2020-02-17T07:11:39+01:00 more robust caching of quasiimmut_field when applied to *constants* (which is the common case after all!) --HG-- branch : warmup-improvements-various - - - - - 03571504 by Carl Friedrich Bolz-Tereick at 2020-02-17T07:40:17+01:00 when tracing, we know that newly allocated frames must be different from the standard frame --HG-- branch : warmup-improvements-various - - - - - 4e810466 by Carl Friedrich Bolz-Tereick at 2020-02-17T13:54:03+01:00 fix a generator corner case --HG-- branch : warmup-improvements-various - - - - - 70e14a03 by Carl Friedrich Bolz-Tereick at 2020-02-17T19:54:03+01:00 remove bogus quasi-immutable declaration on the ExecutionContext. the ec is never constant, so it doesn't help to make its fields quasi-immutable --HG-- branch : warmup-improvements-various - - - - - 315d87d0 by Carl Friedrich Bolz-Tereick at 2020-02-21T11:42:16+01:00 fix tests due to changen in guard_not_invalidated --HG-- branch : warmup-improvements-various - - - - - 19783278 by Carl Friedrich Bolz-Tereick at 2020-02-22T19:06:18+01:00 merge default --HG-- branch : warmup-improvements-various - - - - - 927f1aa0 by Carl Friedrich Bolz-Tereick at 2020-02-23T19:15:50+01:00 merge heads --HG-- branch : warmup-improvements-various - - - - - 76eab9a7 by Carl Friedrich Bolz-Tereick at 2020-02-26T10:56:16+01:00 merge warmup-improvements-various: improve warmup speed of PyPy - a few minor tweaks in the interpreter - since tracing guards is super costly, work harder at not emitting too many guard_not_invalidated while tracing - optimize quasi_immut during tracing - optimize loopinvariant calls during tracing - a small optimization around non-standard virtualizables during tracing this improves warmup time by around ~5-20% - - - - - 5faa0309 by Carl Friedrich Bolz-Tereick at 2020-02-26T10:57:06+01:00 document branch - - - - - 3f1642ca by Carl Friedrich Bolz-Tereick at 2020-02-26T10:58:04+01:00 merge default --HG-- branch : py3.6 - - - - - 12 changed files: - pypy/doc/whatsnew-head.rst - pypy/interpreter/pyframe.py - pypy/interpreter/pyopcode.py - pypy/module/pypyjit/test_pypy_c/test_micronumpy.py - rpython/jit/metainterp/heapcache.py - rpython/jit/metainterp/optimizeopt/heap.py - rpython/jit/metainterp/optimizeopt/test/test_optimizeopt.py - rpython/jit/metainterp/pyjitpl.py - rpython/jit/metainterp/test/test_heapcache.py - rpython/jit/metainterp/test/test_quasiimmut.py - rpython/jit/metainterp/test/test_threadlocal.py - rpython/jit/metainterp/test/test_tracingopts.py View it on GitLab: https://foss.heptapod.net/pypy/pypy/compare/76cfea066db1e2591bd3bc613e611196092d776d...3f1642ca13cebdab3a90f069b9206a54a046a192 --- View it on GitLab: https://foss.heptapod.net/pypy/pypy/compare/76cfea066db1e2591bd3bc613e611196092d776d...3f1642ca13cebdab3a90f069b9206a54a046a192 You're receiving this email because of your account on foss.heptapod.net.
