gh-121647: Define _Py_TYPEOF macro on more compilers by fuhsnn · Pull Request #121648 · python/cpython · GitHub

Extend the _Py_TYPEOF macro to more implementations of typeof and standardized equivalents on C23 and C++11. On MSVC, typeof is enabled through _MSC_VER check; for others, an autoconf probe is implemented.

Issue: Define _Py_TYPEOF on MSVC and other compilers supporting __typeof__ #121647

🤖 New build scheduled with the buildbot fleet by @encukou for commit 85e5cbd 🤖

If you want to schedule another build, you need to add the 🔨 test-with-buildbots label again.

Hello! Sorry for the delay in reviewing.
Could you put the standard variants (__STDC_VERSION__, __cplusplus) first? Otherwise, they won't get used at all on compilers we test with.

Ideally, find a way to use Py_SETREF (which _Py_TYPEOF) in Lib/test/test_cext/extension.c -- which tests on different compiler settings.

Also, I'd prefer not adding the configure check. I don't see much benefit over __STDC_VERSION__, and I'd rather avoid Python.h defining another HAVE_* macro. (And removing it will remove the conflict.)

Thanks for reviewing, I did the PR to see if it gets a better chance than #121643, however cpython has grown to requiring more patches (__attribute__((section)) usage and an already-reported mimalloc bug #134070), so I'm fine patching cpython for my compiler.

On C23 typeof, I recently came across a peculiar GCC behavior that lead to it to silently remove noreturn from function pointers llvm/llvm-project#176070, so for GCC it's probably safer to stick to __typeof__.

Thanks.
Are the patches public? I can't promise a high-priority effort but I'd like to better align CPython with the C standards.

Just tested 3.15 master (default and --disable-gil), in addition to #134070 these are enough for slimcc to pass all tests (sans test_gdb, probably caused by lacking DWARF info).

Do you want to work on this PR, or may I take over?

Does slimcc recognize [[gcc::section, gcc::used]] attributes, with the C23 syntax?
I'm thinking about using those instead, to ensure we're getting GCC semantics rather than blindly applying an attribute called section.

In C23 typeof, I recently came across a peculiar GCC behavior that lead to it to silently remove noreturn from function pointers llvm/llvm-project#176070, so for GCC it's probably safer to stick to typeof.

I don't think this bug is likely to hit CPython, so I'd prefer not working around it.

Does slimcc recognize [[gcc::section, gcc::used]] attributes, with the C23 syntax?

Yes, it does! But the corresponding check of C23 style attributes should be __has_c_attribute(gnu::section) instead.

blindly applying an attribute called section

IMO __attribute__((section)) is kind of "owned" by GNU tool chain so it's somewhat expected for compilers reporting __has_attribute(section) to aim for compatible behavior.

Do you want to work on this PR, or may I take over?

Please do! Thank you for taking care in this.

This PR is stale because it has been open for 30 days with no activity.

Could you put the standard variants (__STDC_VERSION__, __cplusplus) first? Otherwise, they won't get used at all on compilers we test with.

@vstinner already did this in 9e5e1f9

Also, I'd prefer not adding the configure check. I don't see much benefit over __STDC_VERSION__, and I'd rather avoid Python.h defining another HAVE_* macro. (And removing it will remove the conflict.)

I agree we should not add another HAVE_* macro.

IMHO this now just boils down to change

cpython/Include/pyport.h

Line 545 in d125f00

#elif defined(__GNUC__) || defined(__clang__)

to

#elif defined(__GNUC__) || defined(__clang__) || (defined(_MSC_VER) && _MSC_VER >= 1939)

to gain back safety warnings on Windows in case of mismatching pointers:

cpython/Include/cpython/object.h

Lines 349 to 351 in d125f00

    
            * The memcpy() implementation does not emit a compiler warning if 'src' has 
        
            * not the same type than 'src': any pointer type is accepted for 'src'. 
        
            */

which is very wortwhile IMHO.

@encukou:

Also, I'd prefer not adding the configure check. I don't see much benefit over STDC_VERSION, and I'd rather avoid Python.h defining another HAVE_* macro. (And removing it will remove the conflict.)

If Python is built with compiler A which supports __typeof()__, the HAVE_TYPEOF macro is defined. But if you build a C extension with a different compiler (compiler B) which doesn't support __typeof()__, <Python.h> will use __typeof__() which ends up with a build error. I don't think that we should check for __typeof()__ in configure. Checking for C23, C++11, or a specific compiler should be fine.

@fuhsnn: Can you update your PR on the main branch and remove HAVE_TYPEOF?

Extend the _Py_TYPEOF macro to use __typeof__() with MSVC 17.9 and newer, or decltype() under C++11 and newer.

Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

I added Py_CLEAR() and Py_SETREF() tests in test_cppext with commit 36c7440. So this change should now be tested with C++.

I merged your updated (simpler) change, thanks! Sorry, it took a while to merge it. But better late than never ;-)

IMO it's too late to backport this change to the 3.15 branch. I prefer to only change the main branch (Python 3.16) change to have enough time to test the change properly (starting with Python 3.16 alpha1 release, scheduled for 2026-10-13).

Oh, test_cppext fails on Windows:

extension.cpp(299): error C3861: '__typeof__': identifier not found

Toolkit version: "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.44.35207\bin\HostX86\x64\cl.exe".

I suppose that decltype() should be used instead of __typeof__() when using C++. I wrote PR gh-157267 to try that.

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot AMD64 Windows PGO 3.x (tier-1) has failed when building commit 05b6061.

What do you need to do:

Don't panic.
Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
