That's cool! What version would you do the patch for?
Apart from wine, I guess mingw should have the biggest need for the
MS ABI in order to support AMD64.

I think, it isn't to hard introducing this attributes to the AMD64
abi's.
What names should we use for it? I suggest "x86_64_ms" and
"x86_64_linux".
For code bridging MS and GNU codebases (such as wine, or lets say,
GNU
runtime in windows if it ends up with non-MS calling convetions).
Then you want to use the attributes to call code from foreign world.
x86_64_linux is probably not very exact - we intended the ABI to be
generally useful for non-linux or non-GNU system (i.e. specified as
System V Application Binary Interface AMD64 Architecture Processor
Supplement with GCC as reference implementation). I believe Sparc
and
other unixes are more or less following it too.
For MS I would probably suggest ms_abi (it makes it cleaner that the
attribute is affecting calling convetion). For our abi I am not
sure, we
can sysv_abi or something else...
I will prepare an patch for it. For me "ms_abi" and "sysv_abi" is
fine.
