Member Function Documentation

int SparcSubtarget::getAdjustedFrameSize

(

int

stackSize

)

const

Given a actual stack size as determined by FrameInfo, this function returns adjusted framesize which includes space for register window spills and arguments.

int64_t llvm::SparcSubtarget::getStackPointerBias

(

)

const [inline]

The 64-bit ABI uses biased stack and frame pointers, so the stack frame of the current function is the area from [sp+BIAS] to [fp+BIAS].
