gcc: * config/mips/mips.h (ISA_HAS_FP4): Add MIPS32R2 + 64bit fpu combination. (ISA_HAS_MXHC1): True if ISA supports mfhc1 and mthc1 opcodes. (ASM_SPEC): Pass along -mfp32 and -mfp64. * config/mips/mips.c (mips_split_64bit_move): Use gen_mthc1 to set high part of FP register when in 64-bit FP register mode. Similarly use gen_mfhc1 to load high part of FP register. (override_options): Allow -mgp32 and -mfp64 combination if ISA_HAS_MXHC1 (currently for O32 only). (mips_cannot_change_mode_class): If floating-point registers are bigger than word size. disallow conversion of float register from a large integer mode to a float mode smaller than the float register size. (mips_class_max_nregs): Handle float registers case seperately. * config/mips/mips.md (define_constants): Add UNSPEC_MFHC1, UNSPEC_MTHC1. (movdi_32bit): Use !TARGET_FLOAT64 in condition pattern. (movdf_hardfloat_32bit): Similarly. (movdi_gp32_fp64): New DImode pattern for MIPS32R2 which optionally support a full 64-bit fpu. (mthc1): New pattern to generate MTHC1 instruction. (mfhc1): New pattern to generate MFHC1 instruction. * doc/invoke.texi (MIPS Options): Document the -mgp32 -mfp64 option for the MIPS32R2 and mention its use under O32 ABI. gcc/testsuite: * gcc.target/mips/mips.exp (dg-mips-options): Handle parsing of -mfp64, allowable when ISA >= 33 and float is enabled. * gcc.target/mips/mips32r2-mxhc1.c: New test for checking the use of mthc1 and mfhc1 patterns.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
