From 5c1a2e639a26f1582318ac6f547a8819ea7c6034 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Mon, 2 Nov 2015 16:34:16 +0000 Subject: Move constant folds for maths functions to new file The new routines operate on the built-in enum rather than on tree decls. The idea is to extend this to handle internal functions too, with a combined enum for both. The patch also moves fold_fma too, with the same prototype. The long-term plan is to replace FMA_EXPR with an internal function, for consistency with the way that things like SQRT will be handled. Tested on x86_64-linux-gnu, arm-linux-gnueabi and aarch64-linux-gnu. gcc/ * builtins.h (fold_fma): Move to fold-const-call.h. * builtins.c: Include fold-const-call.h. (mathfn_built_in_2): New function, split out from... (mathfn_built_in_1): ...here. (do_real_to_int_conversion, fold_const_builtin_pow) (fold_const_builtin_logb, fold_const_builtin_significand) (fold_const_builtin_load_exponent, do_mpfr_arg1, do_mpfr_arg2) (do_mpfr_arg3, do_mpfr_sincos, do_mpfr_bessel_n, do_mpc_arg1): Delete. (fold_builtin_sincos): Use fold_const_call to handle constants. (fold_builtin_1, fold_builtin_2, fold_builtin_3): Add explicit checks for ERROR_MARK. Use fold_const_call to handle constant folds for math functions. (fold_fma): Move to fold-const-call.c. * fold-const.c: Include fold-const-call.h. * Makefile.in (OBJS): Add fold-const-call.o. (PLUGIN_HEADERS): Add fold-const-call.h. * realmpfr.h (real_from_mpfr): Allow the format to be specified directly. * realmpfr.c (real_from_mpfr): Likewise. * fold-const-call.h, fold-const-call.c: New files.
