[LLVMdev] neon registers llvm using
Hi, Everyone:
Can anyone let me know the default NEON registers llvm going to use with armv7 devices?
For example, d10 and d11 are treated as default zero? I am using Xcode5 + llvm and I got a case that compiler will generate neon codes
" vst.8 {d10, d11}, [r1] "
from C codes:
"int aMV[4];
......
aMV[0] = aMV[1] = aMV[2] = aMV[3] = 0; "
and I

[LLVMdev] Contributing the Apple ARM64 compiler backend
> Are these two backends ABI compatible?
They should be, where there's overlap. AArch64 doesn't have any MachO
support at the moment. ARM64 does have ELF support (obviously with
less testing than AArch64's). Any ABI discrepancy would be considered
a bug.

I have seen https://developer.apple.com/library/ios/documentation/Xcode/Conceptual/iPhoneOSABIReference/Articles/ARMv6FunctionCallingConventions.html,
document says ARMv6 call convention is similar to ARMv7, and document refers to AAPCS, but also describes some discrepencies, like The stack is 4-byte aligned at the point of function calls. I faced here with bugs, due stack alignme...

[LLVMdev] Hash Table Virtual Calls with Conflict Resolution Stubs
Hi everyone,
I'm the developer of the Loci programming language (
http://loci-lang.org ), for which the compiler is a front-end for
LLVM. I would like to say that LLVM has been extremely useful for the
development of the compiler and so thank you everyone for building
this amazing system.
---- Virtual Method Calls ----
While most aspects of the language map well onto LLVM IR, it seems
