I'm about to post a patch that adds a mode argument to LEGITIMATE_CONSTANT_P. Since LEGITIMATE_CONSTANT_P is closely associated with force_const_mem (by explicit calls on some targets), I thought I'd better add a mode argument there too. The mode argument will be used more after that L_C_P patch. Tested by building all-gcc for these targets: alpha-linux-gnu arm-linux-gnueabi avr-rtems bfin-elf cris-elf fr30-elf frv-linux-gnu h8300-elf ia64-linux-gnu iq2000-elf lm32-elf m32c-elf m32r-elf m68k-linux-gnu mcore-elf mep-elf microblaze-elf mips-linux-gnu mmix mn10300-elf moxie-elf hppa64-hp-hpux11.23 pdp11 picochip-elf powerpc-linux-gnu rx-elf s390-linux-gnu score-elf sh-linux-gnu sparc-linux-gnu spu-elf xstormy16-elf v850-elf vax-netbsdelf xtensa-elf and making sure that the output for gcc.dg, gcc.c-torture and g++.dg didn't change. I also checked that there were no new warnings in the build log. Also tested on arm-linux-gnueabi in the normal way. OK to install?
