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.
