* gh-95853: WASM: better version and asset handling in scripts (GH-96045)Christian Heimes2022-08-191-2/+3

* gh-90536: Add support for the BOLT post-link binary optimizer (gh-95908)Kevin Modzelewski2022-08-181-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add support for the BOLT post-link binary optimizer Using [bolt](https://github.com/llvm/llvm-project/tree/main/bolt) provides a fairly large speedup without any code or functionality changes. It provides roughly a 1% speedup on pyperformance, and a 4% improvement on the Pyston web macrobenchmarks. It is gated behind an `--enable-bolt` configure arg because not all toolchains and environments are supported. It has been tested on a Linux x86_64 toolchain, using llvm-bolt built from the LLVM 14.0.6 sources (their binary distribution of this version did not include bolt). Compared to [a previous attempt](https://github.com/faster-cpython/ideas/issues/224), this commit uses bolt's preferred "instrumentation" approach, as well as adds some non-PIE flags which enable much better optimizations from bolt. The effects of this change are a bit more dependent on CPU microarchitecture than other changes, since it optimizes i-cache behavior which seems to be a bit more variable between architectures. The 1%/4% numbers were collected on an Intel Skylake CPU, and on an AMD Zen 3 CPU I got a slightly larger speedup (2%/4%), and on a c6i.xlarge EC2 instance I got a slightly lower speedup (1%/3%). The low speedup on pyperformance is not entirely unexpected, because BOLT improves i-cache behavior, and the benchmarks in the pyperformance suite are small and tend to fit in i-cache. This change uses the existing pgo profiling task (`python -m test --pgo`), though I was able to measure about a 1% macrobenchmark improvement by using the macrobenchmarks as the training task. I personally think that both the PGO and BOLT tasks should be updated to use macrobenchmarks, but for the sake of splitting up the work this PR uses the existing pgo task. * Simplify the build flags * Add a NEWS entry * Update Makefile.pre.in Co-authored-by: Dong-hee Na <donghee.na92@gmail.com> * Update configure.ac Co-authored-by: Dong-hee Na <donghee.na92@gmail.com> * Add myself to ACKS * Add docs * Other review comments * fix tab/space issue * Make it more clear that --enable-bolt is experimental * Add link to bolt's github page Co-authored-by: Dong-hee Na <donghee.na92@gmail.com>
* gh-90928: Statically Initialize the Keywords Tuple in Clinic-Generated Code ↵Eric Snow2022-08-111-0/+1
| | | | | | | | | | | | | | | | (gh-95860) We only statically initialize for core code and builtin modules. Extension modules still create the tuple at runtime. We'll solve that part of interpreter isolation separately. This change includes generated code. The non-generated changes are in: * Tools/clinic/clinic.py * Python/getargs.c * Include/cpython/modsupport.h * Makefile.pre.in (re-generate global strings after running clinic) * very minor tweaks to Modules/_codecsmodule.c and Python/Python-tokenize.c All other changes are generated code (clinic, global strings).
* gh-93744: Remove configure --with-cxx-main option (#95651)Victor Stinner2022-08-051-3/+2
| | | | | | | | | | | | Remove the "configure --with-cxx-main" build option: it didn't work for many years. Remove the MAINCC variable from configure and Makefile. The MAINCC variable was added by the issue gh-42471: commit 0f48d98b740110a672b62d467af192ec160e56ba. Previously, --with-cxx-main was named --with-cxx. Keep CXX and LDCXXSHARED variables, even if they are no longer used by Python build system.

* gh-93649: Split vectorcall testing from _testcapimodule.c (GH-94549)Petr Viktorin2022-07-081-1/+1
| | | | | | | | | | | | | | The `_testcapimodule.c` file is getting too large to work with effectively. This PR lays out a general structure of how tests can be split up, with more splitting to come later if the structure is OK. Vectorcall tests aren't the biggest issue -- it's just an area I want to work on next, so I'm starting here. An issue specific to vectorcall tests is that it wasn't clear that e.g. `MethodDescriptor2` is related to testing vectorcall: the `/* Test PEP 590 */` section had an ambiguous end. Separate file should make things like this much clearer. OTOH, for some pieces it might not be clear where they should be -- I left `meth_fastcall` with tests of the other calling conventions. IMO, even with the ambiguity it's still worth it to split the huge file up. I'm not sure about the buildsystem changes, hopefully CI will tell me what's wrong. @vstinner, @markshannon: Do you think this is a good idea? Automerge-Triggered-By: GH:encukou

| | | | | | | | All install targets use the "all" target as synchronization point to prevent race conditions with PGO builds. PGO builds use recursive make, which can lead to two parallel `./python setup.py build` processes that step on each others toes. "test" targets now correctly compile PGO build in a clean repo.

Move Include/token.h to Include/internal/pycore_token.h. Including this header file now requires that the Py_BUILD_CORE macro is defined. It no longer checks for the Py_LIMITED_API macro.

* gh-84461: Add HOSTRUNNER for program to run Python executable (GH-91931)Ethan Smith2022-04-281-9/+11
| | | | | | | `HOSTRUNNER` is a program which can be used to run `BUILDPYTHON` for the host platform (for example, `python.js` requires `node`). Also change depedencies from `build_all` to `all` so that targets which can't build everything (e.g. WASM) can still run `buildbottest` and `pythoninfo`. cc @tiran
