Move the Mips target to storing the ABI in the TargetMachine rather than on MipsSubtargetInfo. This required a bit of massaging in the MC level to handle this since MC is a) largely a collection of disparate classes with no hierarchy, and b) there's no overarching equivalent to the TargetMachine, instead only the subtarget via MCSubtargetInfo (which is the base class of TargetSubtargetInfo). We're now storing the ABI in both the TargetMachine level and in the MC level because the AsmParser and the TargetStreamer both need to know what ABI we have to parse assembly and emit objects. The target streamer has a pointer to the one in the asm parser and is updated when the asm parser is created. This is fragile as the FIXME comment notes, but shouldn't be a problem in practice since we always create an asm parser before attempting to emit object code via the assembler. The TargetMachine now contains the ABI so that the DataLayout can be constructed dependent upon ABI. All testcases have been updated to use the -target-abi command line flag so that we can set the ABI without using a subtarget feature. Should be no change visible externally here. llvm-svn: 227102

Summary: There are two functional changes: 1) The directive is not expanded for the ASM->ASM code path. 2) If PIC is not set, there's no expansion for the ASM->OBJ code path (same behaviour as GAS).

[mips] Move expansion of .cpsetup to target streamer. Summary: There are two functional changes: 1) The directive is not expanded for the ASM->ASM code path. 2) If PIC is not set, there's no expansion for the ASM->OBJ code path (same behaviour as GAS).

[mips][ias] Implement .cpreturn directive. Summary: Based on a patch by David Chisnall. I've modified the original patch as follows: * Moved the expansion to the TargetStreamers so that the directive isn't expanded when emitting assembly. * Fixed an operand order bug. * Changed the move instructions from DADDu to OR to match recent changes to GAS.
