* gh-118335: Make REGEN_JIT_COMMAND empty if tier2 interpreter enabled (#118493)Guido van Rossum2024-05-011-9/+15

* gh-118335: Configure Tier 2 interpreter at build time (#118339)Guido van Rossum2024-05-011-2/+10
| | | | | | | | | | | | | | | | | | | | | | The code for Tier 2 is now only compiled when configured with `--enable-experimental-jit[=yes|interpreter]`. We drop support for `PYTHON_UOPS` and -`Xuops`, but you can disable the interpreter or JIT at runtime by setting `PYTHON_JIT=0`. You can also build it without enabling it by default using `--enable-experimental-jit=yes-off`; enable with `PYTHON_JIT=1`. On Windows, the `build.bat` script supports `--experimental-jit`, `--experimental-jit-off`, `--experimental-interpreter`. In the C code, `_Py_JIT` is defined as before when the JIT is enabled; the new variable `_Py_TIER2` is defined when the JIT *or* the interpreter is enabled. It is actually a bitmask: 1: JIT; 2: default-off; 4: interpreter.

* gh-117845: Detect libedit hook function signature in configure (#117870)Joshua Root2024-04-171-0/+50
| | | | | | Older libedit versions (like Apple's) use a different type signature for rl_startup_hook and rl_pre_input_hook. Add a configure check to determine which signature is accepted by introducing the Py_RL_STARTUP_HOOK_TAKES_ARGS macro in pyconfig.h.

* gh-71052: Fix several Android build issues (#115955)Malcolm Smith2024-02-291-7/+40
| | | | | | | | | | | | | | | | | | | This change is part of the work on PEP-738: Adding Android as a supported platform. * Remove the "1.0" suffix from libpython's filename on Android, which would prevent Gradle from packaging it into an app. * Simplify the build command in the Makefile so that libpython always gets given an SONAME with the `-Wl-h` argument, even if the SONAME is identical to the actual filename. * Disable a number of functions on Android which can be compiled and linked against, but always fail at runtime. As a result, the native _multiprocessing module is no longer built for Android. * gh-115390 (bee7bb331) added some pre-determined results to the configure script for things that can't be autodetected when cross-compiling; this change adds Android to these where appropriate. * Add a couple more pre-determined results for Android, and making them cover iOS as well. This means the --enable-ipv6 configure option will no longer be required on either platform.

* gh-115765: Don't use deprecated AC_CHECK_TYPE macro in configure.ac (#115792)Erlend E. Aasland2024-02-221-0/+8

* gh-111225: Link extension modules against libpython on Android (#115780)Malcolm Smith2024-02-211-5/+8
| | | | | | | | | | | | | | Part of the work on PEP 738: Adding Android as a supported platform. * Rename the LIBPYTHON variable to MODULE_LDFLAGS, to more accurately reflect its purpose. * Edit makesetup to use MODULE_LDFLAGS when linking extension modules. * Edit the Makefile so that extension modules depend on libpython on Android and Cygwin. * Restore `-fPIC` on Android. It was removed several years ago with a note that the toolchain used it automatically, but this is no longer the case. Omitting it causes all linker commands to fail with an error like `relocation R_AARCH64_ADR_PREL_PG_HI21 cannot be used against symbol '_Py_FalseStruct'; recompile with -fPIC`.
* gh-114099: Refactor configure and Makefile to accomodate non-macOS ↵Russell Keith-Magee2024-02-121-174/+209
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | frameworks (#115120) Part of the PEP 730 work to add iOS support. This change lays the groundwork for introducing iOS/tvOS/watchOS frameworks; it includes the structural refactoring needed so that iOS branches can be added into in a subsequent PR. Summary of changes: * Updates config.sub to the 2024-01-01 release. This is the "as released" version of config.sub. * Adds a RESSRCDIR variable to allow sharing of macOS and iOS Makefile steps. * Adds an INSTALLTARGETS variable so platforms can customise which targets are actually installed. This will be used to exclude certain targets (e.g., binaries, manfiles) from iOS framework installs. * Adds a PYTHONFRAMEWORKINSTALLNAMEPREFIX variable; this is used as the install name for the library. This is needed to allow for iOS frameworks to specify an @rpath-based install name. * Evaluates MACHDEP earlier in the configure process so that ac_sys_system is available. * Modifies _PYTHON_HOST_PLATFORM evaluation for cross-platform builds so that the CPU architecture is differentiated from the host identifier. This will be used to generate a _PYTHON_HOST_PLATFORM definition that includes ABI information, not just CPU architecture. * Differentiates between SOABI_PLATFORM and PLATFORM_TRIPLET. SOABI_PLATFORM is used in binary module names, and includes the ABI, but not the OS or CPU architecture (e.g., math.cpython-313-iphonesimulator.dylib). PLATFORM_TRIPLET is used as the sys._multiarch value, and on iOS will contains the ABI and architecture (e.g., iphoneos-arm64). This differentiation hasn't historically been needed because while macOS is a multiarch platform, it uses a bare darwin as PLATFORM_TRIPLE. * Removes the use of the deprecated -Wl,-single_module flag when compiling macOS frameworks. * Some whitespace normalisation where there was a mix of spaces and tabs in a single block.
