Thanks for reporting the issue.
The patch series has been tested, and regression tests have been executed for
x86_64-w64-mingw32. Could you please provide more details on
which patch triggers the regression? 
It looks more like binutils changes.

--- Comment #3 from Sergei Trofimovich <slyfox at gcc dot gnu.org> ---
I got a similar failure for `--target=i686-w64-mingw32`. It is probably
slightly dependent on system headers and binutils version. Mine is
binutils-2.42.

I extracted the following self-contained example to crash the build:

// $ cat __main.c.c
extern void *__CTOR_LIST__[];
void __do_global_dtors() {
  if (__CTOR_LIST__[0])
    for (;;)
      ;
}

Crashing:

$ gcc/xgcc -Bgcc/  -fbuilding-libgcc -fno-stack-protector   -c __main.c.c -o
__main.o -O2

/tmp/ccMxDwki.s: Assembler messages:

I wonder if you can reproduce it with this sample.

`gcc` produces the following assembly:

$ gcc/xgcc -Bgcc  -fbuilding-libgcc -fno-stack-protector   -S __main.c.c -o -
-O2

        .file   "__main.c.c"
        .text
        .p2align 4
        .globl  ___do_global_dtors
        .def    ___do_global_dtors;     .scl    2;      .type   32;     .endef
___do_global_dtors:
        movl    ___CTOR_LIST__, %eax
        testl   %eax, %eax
        je      L1

        jmp     L3
        .p2align 4,,10
        .p2align 3

        ret
        .ident  "GCC: (GNU) 15.0.0 99999999 (experimental)"
        .section        .rdata$refptr.__CTOR_LIST__, "dr"

        .linkonce       discard
refptr.__CTOR_LIST__:
        .quad   __CTOR_LIST__

`.quad   __CTOR_LIST__` looks wrong for a 32-bit target.

For comparison `gcc-13` produces slightly different result:

$ i686-w64-mingw32-gcc-13.3.0 -fbuilding-libgcc -fno-stack-protector   -S
__main.c.c -o - -O2

Missing braces around `PE_COFF_EXTERN_DECL_SHOULD_BE_LEGITIMIZED`

While there, can you perhaps rename:

PE_COFF_EXTERN_DECL_SHOULD_BE_LEGITIMIZED

to

PE_COFF_LEGITIMIZE_EXTERN_DECL ?

What's the progression of GCC for aarch64-windows-gnu? How long would it be
done? I want to buy a surface pro 11 to use it.

Then just merge it into the main repo if it works. I have no time for testing
because my machine is super slow and I have no idea what’s going on.

BTW, it is still insane Microsoft employee would ask Microsoft shareholder to

First, the bug is not caused by me and I am just reporting the issue here. Why
should I waste my time to test for him?

Second, I am tired of building compilers again and again just to fix a
regression every day. My machine is super slow with no SSD.

BTW do I even make a decision on whether a patch would get merged into GCC? Did
you merge my patch on fixing libstdc++’s abi break? Oh it does not follow your
“code standard” plus you hate me for that freestanding thing and I get it. Ok,
then fix it yourself.

Sorry, I am not going to do either of them. I am not going to test it and I am
not going to fix the ABI bug. It is better you don’t fix the ABI regression and
let the GNU/Linux die.

Your attitude and behaviour is not acceptable, as you've been told many times
before.

    i386: Fix regression after refactoring legitimize_pe_coff_symbol,
ix86_GOT_alias_set and PE_COFF_LEGITIMIZE_EXTERN_DECL [PR115635]

    This patch fixes 3 bugs reported after merging the "Add DLL
    import/export implementation to AArch64" series.
    https://gcc.gnu.org/pipermail/gcc-patches/2024-June/653955.html The
    series refactors the i386 codebase to reuse it in AArch64, which
    triggers some bugs.

    Bug 115661 - [15 Regression] wrong code at -O{2,3} on x86_64-linux-gnu
    since r15-1599-g63512c72df09b4
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115661

    Bug 115635 - [15 regression] Bootstrap fails with failed self-test
    with the rust fe (diagnostic-path.cc:1153: test_empty_path: FAIL:
    ASSERT_FALSE ((path.interprocedural_p ()))) since
    r15-1599-g63512c72df09b4
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115635

    Issue 1. In some code, i386 has been relying on the
    legitimize_pe_coff_symbol call on all platforms and should return
    NULL_RTX if it is not supported.

    Fix: NULL_RTX handling has been added when the target does not support
    PECOFF.

    Issue 2. ix86_GOT_alias_set is used on all platforms and cannot be
    extracted to mingw.

    Fix: ix86_GOT_alias_set has been returned as it was and is used on all
    platforms for i386.

    Bug 115643 - [15 regression] aarch64-w64-mingw32 support today breaks
    x86_64-w64-mingw32 build cannot represent relocation type BFD_RELOC_64
    since r15-1602-ged20feebd9ea31
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115643

    Issue 3. PE_COFF_EXTERN_DECL_SHOULD_BE_LEGITIMIZED has been added and
    used with a negative operator for a complex expression without braces.

    Fix: Braces has been added, and
    PE_COFF_EXTERN_DECL_SHOULD_BE_LEGITIMIZED has been renamed to
    PE_COFF_LEGITIMIZE_EXTERN_DECL.
