llvm dev - Mar 2009 - [LLVMdev] Question on X86-64 ABI support?

Hi,
In latest LLVM2.5, the X86-64 ABI is now supporting, which follows the System-V
x86-64 ABI. But in current industry, there are two popular ABIs for X86-64:
l          System-V X86-64 ABI.
l          UEFI (www.uefi.org<http://www.uefi.org/>) X86-64 ABI. I know in
future GCC-4.4.0 will support it. Now I have a beta version gcc4.4.0.

Because UEFI should be very sensitive on the optimization, FLASH size equals to
$, is there any plan to support the UEFI x86-64 ABI in LLVM?

Hmm, interesting... I've never heard of it.

As far as I know, nobody else has expressed any interest... patches
are welcome, though.
