RFC: Adding Support For Vectorcall Calling Convention
...x64 calling convention while adding
support for HVA and vector types.
There are four main differences:
- Floating-point types are considered vector types just like __m128,
__m256 and __m512. The first 6 vector typed arguments are
saved in physical registers XMM0/YMM0/ZMM0 until XMM5/YMM5/ZMM5.
- After vector types and integer types are allocated, HVA types are
allocated, in ascending order, to unused vector registers
XMM0/YMM0/ZMM0 to XMM5/YMM5/ZMM5.
- Just like in the default x65 CC, Shadow space is allocated for
vector/HVA types. The size is fixed to 8 byte...

Are you sure that these binutils support AVX and FMA? (Currently libFLAC
doesn't contain AVX and FMA instructions). If they aren't supported then
it's better to include them too into

[LLVMdev] [lldb-dev] How is variable info retrieved in debugging for executables generated by llvm backend?
Thank you, Clayton. This is very helpful.
We use the LLDB specific GDB remote extensions, and our debugger server
supports "qRegisterInfo" package. "reg 0x3c" is the frame pointer.
In the example mentioned above, we have SP = FP - 40 for current call frame.
And variable "a" is stored at address (FP + -24) from asm instruction [FP +
-24] = R3;;
Thus we can conclude
