- Authentication-results: sourceware.org; auth=none
The first in a series of patch sets to implement the Go interfaces
I proposed a week or so ago, but mostly split into smaller pieces.
These patches will also include support for complex types as I go,
since Go needs them, and performing both updates at the same time
will make things easier.
This first set includes x86_64-linux and x86_64-cygwin.
It leaves x86_64-darwin in a broken state, but I'm unsure why it
has a completely different assembly file, rather than merely using
the preprocessor to handle the __USER_LABEL_PREFIX__. I'm hoping
that someone who can test darwin can do this update.
The existing win64 support was poor, having a significant amount
of failures (and some xfails to cover that up). IMO the biggest
problem there was trying to combine it with the 32-bit targets.
The ABI is significantly different, and the amount of ifdefs
needed to force it in was ... ugly.
It leaves the visual studio build broken, in that I totally
rewrote all of the win64.S assembly, but did not keep the microsoft
assembly. Hopefully someone who cares about VS can handle that.
