* emit-rtl.c (global_rtl): Update comment. (const_double_htab, const_double_htab_hash, const_double_htab_hash, lookup_const_double): New. (const_int_htab_hash, const_int_htab_eq): Remove const qualifiers, which cause tons of warnings with RTL checking on. (gen_rtx_CONST_DOUBLE): Deleted. (const_double_from_real_value): New function - bears some resemblance to the former immed_real_const_1. (immed_double_const): Moved here from varasm.c and simplified. (gen_rtx_REG): Make REGNO unsigned to squelch warnings. (gen_rtx_SUBREG): Use gen_rtx_raw_SUBREG. (gen_rtx): Use immed_double_const. (init_emit_once): Initialize the const_double_htab. Use REAL_VALUE_FROM_INT where possible. Can now use CONST_DOUBLE_FROM_REAL_VALUE when setting up const_tiny_rtx. * varasm.c (struct varasm_status): Remove x_const_double_chain. (const_double_chain, immed_real_const, clear_const_double_mem): Delete. (immed_double_const, immed_real_const_1): Moved to emit-rtl.c. (init_varasm_status, mark_varasm_status): Don't touch x_const_double_chain. * output.h: Delete prototype for clear_const_double_mem. * real.h: Make REAL_VALUE_TYPE a macro again. Remove leading '0' slot from all CONST_DOUBLE_FORMAT definitions. Prototype const_double_from_real_value, not immed_real_const_1, and use it to define CONST_DOUBLE_FROM_REAL_VALUE. Define new macro CONST_DOUBLE_ATOF. * rtl.h (CONST_DOUBLE_CHAIN): Kill. (CONST_DOUBLE_LOW, CONST_DOUBLE_HIGH): Adjust. (gen_rtx_CONST_DOUBLE, immed_real_const): Delete prototypes. (gen_rtx_REG): Second arg is unsigned. * gengenrtl.c (special_rtx): Take out CONST_DOUBLE. (excluded_rtx): New, return true for CONST_DOUBLE. (genmacro): Write nothing for excluded codes. * combine.c (combine_simplify_rtx): Use CONST_DOUBLE_FROM_REAL_VALUE. * expr.c (expand_expr): Likewise. * ggc-common.c (ggc_mark_rtx_children_1): Don't mark the CONST_DOUBLE_CHAIN. * toplev.c (rest_of_compilation): Don't call clear_const_double_mem. * config/rs6000/rs6000.c (rs6000_float_const): Delete. (rs6000_hash_constant): Remove CONST_DOUBLE special case. (toc_hash_eq): Remove CONST_DOUBLE and LABEL_REF special cases. * config/rs6000/rs6000-protos.h: Don't prototype rs6000_float_const. * config/c4x/c4x.md, config/rs6000/rs6000.md: Use CONST_DOUBLE_ATOF. * config/dsp16xx/dsp16xx.md, config/mips/mips.md, config/pa/pa.md: Use CONST_DOUBLE_FROM_REAL_VALUE. * config/sparc/sparc.md, config/sparc/sparc.c: Use immed_double_const.

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*.
