#include "gt-pa.h"
The port-local FUNCTION_ARG_SIZE: ((((MODE) != BLKmode \ ? (HOST_WIDE_INT) GET_MODE_SIZE (MODE) \ : int_size_in_bytes (TYPE)) + UNITS_PER_WORD - 1) / UNITS_PER_WORD) is used by code in pa.c and by ASM_DECLARE_FUNCTION_NAME in som.h. Treating GET_MODE_SIZE as a constant is OK for the former but not the latter, which is used in target-independent code. This caused a build failure on hppa2.0w-hp-hpux11.11. Tested with a cross build of hppa2.0w-hp-hpux11.11. OK to install?
