Almost cosmetic and no functional changes.
gcc/ChangeLog:
* config/xtensa/*: Tabify, and trim trailing spaces.
* config/xtensa/xtensa.h (GP_RETURN, GP_RETURN_REG_COUNT):
Change to GP_RETURN_FIRST and GP_RETURN_LAST, respectively.
* config/xtensa/xtensa.cc (xtensa_function_value,
xtensa_libcall_value, xtensa_function_value_regno_p): Ditto.
(xtensa_expand_prologue): Modify to exit the inspection loops
as soon as the necessity of stack pointer is found.
(xtensa_set_return_address): Change the style of brackets.
* config/xtensa/xtensa.md (set_frame_ptr):
Fix to reflect TARGET_DENSITY.
