- Authentication-results: sourceware.org; auth=none
A massive cleanup of the i686 backend, with all/most ABIs supported
for all targets, not just windows. Which (nearly) eliminates conditional
compilation wrt ABIs, and allows massive code de-duplication.
Like the x86_64 patch set, this breaks Darwin. What I think ought to
happen is that darwin.S should be deleted, and the very minor tweaks
that might be left vs sysv.S should be handled by the preprocessor.
However, I have no access to darwin with which to test.
Like the x86_64 patch set, the masm variant is removed. Again, I have
no way that I could test this. Though win32 support is of course still
working via gas.
With the final patch, building with clang mostly works. For some reason
the unwind tests fail, despite the .eh_frame looking correct. Freebsd
continues to work if you use gcc+gas from ports.
Tested on i686-{linux,cygwin,freebsd10}.
