JIT: Fix compiler warning from visibility attribute in typedef #139981

savannahostrowski · 2025-10-12T04:11:44Z

/Users/runner/work/cpython/cpython/Tools/jit/trampoline.c:13:13: warning: 'visibility' attribute ignored [-Wignored-attributes]
   13 |     typedef DECLARE_TARGET((*jit_func));
      |             ^
/Users/runner/work/cpython/cpython/Tools/jit/jit.h:11:49: note: expanded from macro 'DECLARE_TARGET'
   11 |     _Py_CODEUNIT *__attribute__((preserve_none, visibility("hidden"))) \
      |

This was introduced in #136528. The DECLARE_TARGET macro includes visibility("hidden"), which is valid for forward declarations but gets ignored when used in a typedef, so the compiler is yelling.

LGTM. Basically the same as my PR #140286 I've just closed since @Fidget-Spinner made me aware of yours :)

Just a suggestion:

Tools/jit/trampoline.c

Sorry for being such a pain, this is now merely for my understanding and I hope asking this question here is ok:

When playing with the above Godbolt link, I more or less get the same nice output for jit_stencils-x86_64-unknown-linux-gnu.h in WSL:

    memcpy(code, code_body, sizeof(code_body));
}

whereas on Windows x86_64 I get

which tells me, clang-cl is saving a ton more on the stack here.
Why that big difference? I wouldn't have assumed that from reading https://clang.llvm.org/docs/AttributeReference.html#preserve-none

On X86-64, only RSP and RBP are preserved by the callee. Registers R12, R13, R14, R15, RDI, RSI, RDX, RCX, R8, R9, R11, and RAX now can be used to pass function arguments. Floating-point registers (XMMs/YMMs) still follow the C calling convention.

chris-eibl · 2025-10-18T18:47:42Z

Oh, I think I've found the answer myself: adding __attribute__((ms_abi)) to the _JIT_ENTRY function results in similar code as in the stencil, so it is just following MS ABI ...

chris-eibl · 2025-10-18T19:09:46Z

Maybe also restore the comment

 // Note that this is *not* a tail call:

that got lost in #137961? Because it is utterly important that we use jit_func_preserve_none here and not jit_func, because this would result in a tail call.
