[mips] Align the stack to 16-bytes for mfp64. llvm-svn: 193641
2013-10-30 03:29:03 +08:00
; RUN: llc -march=mipsel < %s | FileCheck %s -check-prefix=32
[MIPS] Implement support for -mstack-alignment. Summary: This is modeled on the implementation for x86 which stores the command line option in a 'StackAlignOverride' field in MipsSubtarget and then uses this to compute a 'stackAlignment' value in MipsSubtarget::initializeSubtargetDependencies. The stackAlignment() method in MipsSubTarget is renamed to getStackAlignment() and returns the computed 'stackAlignment'.

[mips] Explicitly select `mips32r2` CPU for test cases require 64-bit FPU. NFC Support for 64-bit coprocessors on a 32-bit architecture was added in `MIPS32 R2`. llvm-svn: 365507

[MIPS] Use ABI to determine stack alignment. Summary: The stack alignment depends on the ABI (16 bytes for N32 and N64 and 8 bytes for O32), not the CPU type.
