* 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. git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@53409 138bc75d-0d04-0410-961f-82ee72b054a4
