Subject: mips.h (CAN_ELIMINATE): Don't eliminate rap to $fp (s8), but rather HARD_FRAME_POINTE... 
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cfb773f9109b45c452c5a33602b3c2b141737caa;p=gcc.git

mips.h (CAN_ELIMINATE): Don't eliminate rap to $fp (s8), but rather HARD_FRAME_POINTER_REGNUM.

* config/mips/mips.h (CAN_ELIMINATE): Don't eliminate rap to $fp
(s8), but rather HARD_FRAME_POINTER_REGNUM.  Add parentheses
where appropriate.  Make the second reference to
leaf_function_p a function call, as intended.  Reindented.
