Remove REAL_VALUE_FROM_CONST_DOUBLE
To maintain symmetry after the previous removal of CONST_DOUBLE_FROM_REAL_VALUE, this patch also gets rid of REAL_VALUE_FROM_CONST_DOUBLE. All the macro did was copy the contents of CONST_DOUBLE_REAL_VALUE into a temporary real_value structure. In many cases there was no need for this temporary and we could simply use the CONST_DOUBLE_REAL_VALUE directly. For that reason this patch is less automatic than the others. Bootstrapped & regression-tested on x86_64-linux-gnu. Also tested by building one target per CPU directory and checking that there were no new warnings and no changes in testsuite output at -O2. gcc/ * real.h (REAL_VALUE_FROM_CONST_DOUBLE): Delete. * config/aarch64/aarch64.c (aarch64_float_const_zero_rtx_p) (aarch64_print_operand, aarch64_float_const_representable_p) (aarch64_output_simd_mov_immediate): Use CONST_DOUBLE_REAL_VALUE instead of REAL_VALUE_FROM_CONST_DOUBLE. * config/arc/arc.c (arc_print_operand): Likewise. * config/arm/arm.c (arm_const_double_rtx, vfp3_const_double_index) (neon_valid_immediate, arm_print_operand, arm_emit_fp16_const) (vfp3_const_double_for_fract_bits, vfp3_const_double_for_bits): Likewise. * config/arm/arm.md (*arm32_movhf, consttable_4, consttable_8) (consttable_16): Likewise. * config/arm/vfp.md (*movhf_vfp_neon, *movhf_vfp): Likewise. * config/avr/avr.c (avr_print_operand): Likewise. * config/bfin/bfin.md: Likewise (in a define_split). * config/c6x/c6x.md: Likewise (in a define_split). * config/cr16/cr16.c (cr16_const_double_ok): Likewise.
