gcc/ * config/mips/mips.c (mips_split_64bit_move): Use gen_rtx_REG_offset rather than gen_lowpart to change a register from DImode to DFmode. (mips_cannot_change_mode_class): Only allow FPRs to change mode if both FROM and TO are integer modes that are no bigger than 4 bytes. (mips_mode_ok_for_mov_fmt_p): New function. (mips_preferred_reload_class): Use it instead of FLOAT_MODE_P. (mips_secondary_reload_class): Tweak formatting and comments. Use reg_class_subset_p instead of direct comparisons with classes. Only allow direct FPR<->FPR moves for modes that satisfy mips_mode_ok_for_mov_fmt_p. Only allow loads and stores for 4- and 8-byte types. Handle reloads in which X is an FPR. * config/mips/mips.md (*movdi_gp32_fp64): Remove f<-f alternative. (*movdi_64bit): Likewise. (*movsi_internal): Likewise. (*movhi_internal): Likewise. (*movqi_internal): Likewise. From-SVN: r128894
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.
