This patch adds internal functions for simple FLT_FN built-in functions, in cases where an associated optab already exists. Unlike some of the built-in functions, these internal functions never set errno. LDEXP is an odd-one out in that its second operand is an integer. All the others operate on uniform types. The patch also adds a function to query the internal function associated with a built-in function (if any), and another to test whether a given gcall could be replaced by a call to an internal function on the current target (as long as the caller deals with errno appropriately). Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi. gcc/ * builtins.h (associated_internal_fn): Declare. (replacement_internal_fn): Likewise. * builtins.c: Include internal-fn.h (associated_internal_fn, replacement_internal_fn): New functions. * internal-fn.def (DEF_INTERNAL_FLT_FN): New macro. (ACOS, ASIN, ATAN, COS, EXP, EXP10, EXP2, EXPM1, LOG, LOG10, LOG1P) (LOG2, LOGB, SIGNIFICAND, SIN, SQRT, TAN, CEIL, FLOOR, NEARBYINT) (RINT, ROUND, TRUNC, ATAN2, COPYSIGN, FMOD, POW, REMAINDER, SCALB) (LDEXP): New functions. * internal-fn.c: Include recog.h. (unary_direct, binary_direct): New macros. (expand_direct_optab_fn): New function. (expand_unary_optab_fn): New macro. (expand_binary_optab_fn): Likewise. (direct_unary_optab_supported_p): Likewise.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with 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*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
