Also put target flags on SPARC constant pool references. Constant pool entries are accessed exactly the same way as global variables. llvm-svn: 179471

Add support for the SPARC v9 abs44 code model. This is the default model for non-PIC 64-bit code. It supports text+data+bss linked anywhere in the low 16 TB of the address space. llvm-svn: 179473

; abs44: retl
The SPARCv9 ABI returns a float in %f0. This is different from the argument passing convention which puts the first float argument in %f1. With this patch, all returned floats are treated as if the 'inreg' flag were set. This means multiple float return values get packed in %f0, %f1, %f2, ... Note that when returning a struct in registers, clang will set the 'inreg' flag on the return value, so that behavior is unchanged. This also happens when returning a float _Complex. llvm-svn: 199028
