  To: gcc-patches, patches

Hi,

This is a port of libffi to x86-64. The patch runs the testsuite without 
problems both on x86 and x86-64.

I have added some more struct tests, because the tests that were there didn't 
handle the quirks of the x86-64 ABI for small structs.

I have included the configure (against normal practice). If the patch looks 
fine, but my generated configure doesn't, someone else must regenerate it.

Bo.

2002-07-16  Bo Thorsen  <bo@berlioz.suse.de>

	* src/x86/unix64.S: New file that handles argument setup for
	x86-64.

	* src/x86/sysv.S: Don't use this on x86-64.

	* src/x86/ffi.c: Add x86-64 support.
	(merge_classes): Helper function for argument passing.
	(classify_argument): Likewise.
	(examine_argument): Likewise.
	(ffi_prep_args64): Add x86-64 version of this function.
	(ffi_prep_cif_machdep64): Likewise.
	(ffi_fill_return_value): Add function to handle return values. Used
	by the assemblercode in unix64.S.
	(ffi_prep_cif_machdep): Renamed to ffi_prep_cif_machdep32.
	(ffi_prep_cif_machdep): Use this new function to choose between 32 and
	64 bit versions to avoid two functions with identical names.
	(ffi_call): Add dispatcher for x86-64.

	* src/prep_cif.c (ffi_prep_cif): Don't do stack size calculation
	for x86-64.

	* src/ffitest.c (struct6): New test that tests a special case in
	the x86-64 ABI.
	(struct7): Likewise.
	(struct8): Likewise.
	(struct9): Likewise.
	(closure_test_fn): Silence warning about this when it's not used.
	(main): Add the new tests.
	(main): Fix a couple of wrong casts and silence some compiler warnings.

	* include/ffi.h.in: Add x86-64 ABI definition.

	* fficonfig.h.in: Regenerate.
	* Makefile.am: Add x86-64 support.
	* configure.in: Likewise.
	* Makefile.in: Regenerate.
	* configure: Likewise.

2002-06-24  Bo Thorsen  <bo@suse.de>

	* src/types.c: Merge settings for similar architectures.
	Add x86-64 sizes and alignments.

2002-06-23  Bo Thorsen  <bo@suse.de>

	* src/arm/ffi.c (ffi_prep_args): Remove unused vars.
	* src/sparc/ffi.c (ffi_prep_args_v8): Likewise.
	* src/mips/ffi.c (ffi_prep_args): Likewise.
	* src/m68k/ffi.c (ffi_prep_args): Likewise.

My mailer was set up to do word wraps. Doesn't quite work with patches, so 
here is a better one.

For some unknown reason I didn't say anything about the test of this in my 
previous mail. I bootstrapped on x86-64, but this fails in boehm-gc. I will 
start the port of this now. I also bootstrapped on i386 mainline both with 
the patch and without. They both gave this result for me (SuSE 8.0 on an 
athlon):

                === libjava Summary ===

# of expected passes            2540
# of unexpected failures        20
# of expected failures          14
# of untested testcases         146

I haven't checked the unexpected failures, but as I said, I get them both with 
and without the patch.

Can I check this into mainline?

Bo.
