Hi Ramana, Thanks for your comments,
> Please respin using plus_constant instead of gen_addsi3. Here is my feeling about this: I experimented on using plus_constant instead of gen_addsi3. But there are cases when the emitted code is not equivalent for large frames (!const_ok_for_op (val, PLUS)) and leads to complications. We could fix this case with a call to arm_split_constant (PLUS, Pmode, NULL, amount, stack_pointer_rtx, stack_pointer_rtx, 0), but I'm not sure we gain in clarity here. Also for consistency, the same interface change would preferably be needed in the other parts of the arm.c file (that I didn't modify) sharing the same sequence. For instance "arm_expand_epilogue" > Otherwise > this looks good to me. > > Please repost updated patch and I will look at it again. For the reasons expressed above it'd prefer to consider this new change as a separate development with a new patch. For the time being (considering only the original apcs issue) is it OK to apply only the patch as it ? and validate a global gen_addsi3/plus_constant interface review as a separate step ?
