Re: [PATCH, libffi, alpha]: Use FFI_ASSERT in ffi_closure_osf_inner
[replying to an ancient post here..] Uros Bizjak ubiz...@gmail.com writes: Hello! Attached patch fixes libgo reflect test failure with libffi closures. The gccgo compiler started to use FFI closures recently; the compiler passes ffi_type_void for structures with zero members. Why not just pass an FFI_TYPE_STRUCT with zero members? ffi_call form src/alpha/ffi.c allows FFI_TYPE_VOID arguments in non-debug mode through the default: case, but ffi_closure_osf_inner aborts with this type of argument. The patch changes the default case in ffi_closure_osf_inner from abort to FFI_ASSERT, an this way synchronizes argument handling in both cases. 2014-07-21 Uros Bizjak ubiz...@gmail.com * src/alpha/ffi.c: Do not include stdlib.h. (ffi_closure_osf_inner) default: Use FFI_ASSERT instead of abort. Patch was tested with libffi testsuite on alphaev6-linux-gnu. Additionally, the patch fixed reflect test from the libgo testsuite and go.test/test/recover.go test from the gcc testsuite. Why not add an FFI_TYPE_VOID case so it doesn't ever abort if that's expected behaviour? The default case is there to catch unexpected values. AG Uros.

[Patch, moxie] Add moxiebox target
The following binutils patches introduce a new moxie-based target
called moxiebox. Moxiebox is a VM developed by the bitcoin community
to act as a secure, sandboxed execution environment for bitcoin
automation.
See http://github.com/jgarzik/moxiebox for more information.
I'm checking these changes in. There's a config.sub change as well
that I'll submit through the regular process.
Thanks,

[Patch, moxie] Zero- and sign-extend values properly
This patch does three related things for the moxie port...
1. Changes char to be unsigned by default
2. Changes WCHAR_TYPE from long int to unsigned int
3. Zero- and sign-extends values properly, sometimes using the new
sign-extension instructions.
I am committing this change even at this late stage of the GCC release
process because it only touches the moxie target directory.

Ok for the trunk? openSUSE is using the GCC provided libffi, so no, this is not ok (not at this stage anyway). Also proper not-installing libffi would work by disabling the maybe-install-target-libffi at the toplevel, not changing libffi makfiles (which are supposed to be imported from upstream, no?) Thus, add no_install= true; to the libffi target module updated patch attached, checked with a make install that no ffi headers and libraries are installed. If not ok for 4.8, ok for 4.9 when it opens? I'm fine with that variant but I'd like to see another ok. No preference as to whether to target 4.8 or 4.9. Richard. Matthias

[Patch, moxie] Add -mno-crt0 option
This patch adds a -mno-crt0 option, similar to what is found on the
mn10300 port. I have checked it in.
Thanks,

[Patch, moxie] bi-endian support for moxie
Here are some changes in support of a little-endian soft-core
implementation of moxie. We now build multilibs for both endians.
Corresponding binutils changes have already been committed and I am
checking this in. (note: it does include what I believe are
trivially correct doc changes - apologies in advance if I should have
waited for a review).
Thanks,
Anthony Green

[PATCH, moxie] clean up function prologues
The prologue code for functions with large static stack space
requirements was really ugly on moxie. This patch cleans things up
and I am committing this change.

* config/moxie/moxie.c (moxie_expand_prologue): Optimize prologue
for functions with large static stack requirements.
(moxie_expand_epilogue): Use $r12 instead of $r5 for pulling saved
values off of the stack.

No, but very close. There's still the outstanding ARM fp issue (libffi doesn't build for soft-fp targets). I'll sync again when 3.0.11 is final. Chung-Lin, this is related to your VFP support patch. I hope you have time to look at this soon. Let me know if you won't. Thanks, AG

I can understand the Free Software Foundation addition since the file was contributed to it. Simply because of changes that were made to that source file over the years.

I have no objection to removing this if you feel strongly about it. AG
