gcc/ * config/mips/mips.c (mips_symbol_insns_1): Allow LEAs of SYMBOL_FORCE_TO_MEM constants. (mips_rtx_costs): Give a cost of 1 to force_to_mem_operands. (mips16_rewrite_pool_refs_info): New structure. (mips16_rewrite_pool_constant): New function, split out from... (mips16_rewrite_pool_refs): ...here. Take a pointer to a mips16_rewrite_pool_refs_info structure rather than a pointer to a constant pool. Force force_to_mem_operands into memory. (mips16_lay_out_constants): Update call to mips16_rewrite_pool_refs. * config/mips/predicates.md (force_to_mem_operand): New predicate. * config/mips/constraints.md (kf): New constraint. * config/mips/mips.md (*movdi_64bit_mips16): Add a d <- kf alternative.

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*.
