please fix java::lang::Class::initializeClass for mingw32 ia-32 by adding
__thiscall before being involved this bug. surely PR50053 is fixed but i leaved
a kludge toward this bug.

it seems that libffi handles calling convention of method which is cdecl or
stdcall.
but not for thiscall for mingw32 ia-32.

Hmm, this might be another instance for already solved PR/50053.  Could you
recheck, if error is still present for current 4.7 trunk version.

Thanks

Hmm, not sure if you already noticed it, but ffi_call supports by recent patch
thiscall/fastcall convention.
So parts of you patch won't apply mainline.

Don't use this insn, it implies lock prefix and costs hundreds of cycles.

Right the following sequence seems to be better IMHO:

pop %eax
push %ecx
push %eax
mov __ctx, %eax
call fun
pop %ecx
mov %ecx, %(esp)
ret

I'd avoid push and pop insns and go directly with moves and %esp adjustments.
Please see i.e. libitm/config/x86/sjlj.S for some ideas.

IMO, you will need to keep 16byte stack alignment at function call, so:

movl (%esp), %eax
movl %ecx, (%esp)
subl $12, %esp
movl %eax, (%esp)
movl __ctx, %eax
call fun
mov (%esp), %ecx
addl $16, %esp
jmp *%ecx

Ok, here is a variant treating stack-alignment for closure.

ChangeLog

2012-01-31  Kai Tietz  <ktietz@redhat.com>

    * src/prep_cif.c (ffi_prep_cif): Allow for X86_WIN32
    also FFI_THISCALL.
    * src/x86/ffi.c (ffi_closure_THISCALL): Add prototype.
    (FFI_INIT_TRAMPOLINE_THISCALL): New trampoline code.
    (ffi_prep_closure_loc): Add FFI_THISCALL support.
    * src/x86/ffitarget.h (FFI_TRAMPOLINE_SIZE): Adjust size.
    * src/x86/win32.S (ffi_closure_THISCALL): New closure code
    for thiscall-calling convention.
    * testsuite/libffi.call/closure_thiscall.c: New test.
