[LLVMdev] ABI: how to let the backend know that an aggregate should be allocated on stack

See MipsABIInfo::getPaddingType; a similar sort of approach should
work here. (Granted, onstack would be more convenient, but it doesn't
exist at the moment.)

[LLVMdev] Proposed patches for Clang 3.5.1
...ding explicit -target
* r214025 - [Driver][Mips] Check output of -dynamic-linker arguments by the Clang driver
* r214662 - [Mips] Add the `mips64-linux-gnu` target to the test case to check `in128` type handling.

[LLVMdev] ABI: how to let the backend know that an aggregate should be allocated on stack
Hi All,
I am trying to handle the Homogeneous Aggregate for ARM-VFP according to the spec:
C.1.vfp If the argument is a VFP CPRC and there are sufficient consecutive VFP registers of the appropriate type unallocated then the argument is allocated to the lowest-numbered sequence of such registers.
C.2.vfp If the argument is a VFP CPRC then any VFP registers that are unallocated are marked as

The Trouble with Triples
...We construct a TargetMachine and all the other objects using this llvm::Triple.
· The architecture was Triple::mips so everything configures for big-endian even though the target was supposed to be little endian.
CPU Defaults
In LLVM, the default CPU is hardcoded to be MIPS32 (in MipsABIInfo::computeTargetABI()). In Clang, the default CPU for this triple is hardcoded to be MIPS32R2 (in mips::getMipsCPUAndABI()) and clang always passes an explicit CPU to the backend via –target-cpu.

I disagree with this but for now let's assume it's true. The starting point is
incorrect because
