The load of the constant can 304: overlap the load. 305: (andsi3, iorsi3, xorsi3): Replace logical define_insn's with 306: define_expand's that either map directly to the hardware 307: instruction, or have a clobbered register to load the large 308: constant into.

Otherwise use .double. 341: (mips_output_float): If REAL_VALUE_TO_TARGET_FLOAT is defined, use 342: it to split the floating point value into a long integer, and 343: print in out in hex. Otherwise use .float. 344: 345: * dec-osf1.h (new file): Config file for DEC's offical OSF/1 346: product (as opposed to the OSF/1 reference port from OSF). 347: 348: * configure: Support mips-dec-osf1 target. 349: * config.sub: Support mips-dec-osf1 target. 350: 351: * decstatn.h (CPP_PREDEFINES): If CPP_PREDEFINES is defined, don't 352: supply another definition.
