Roger Sayle e82a312b55 real.c (real_powi): New function to calculate the value of a real raised to an integer power, i.e. 
* real.c (real_powi): New function to calculate the value of
	a real raised to an integer power, i.e. pow(x,n) for int n.
	(real_sqrt): Convert to using the faster do_add, do_multiply
	and do_divide API for consistency with the rest of real.c.
	* real.h (real_powi): Prototype here.
	* builtins.c (fold_builtin):  Avoid local variable mode when
	evaluating sqrt at compile time.  Attempt to evaluate pow at
	compile-time, by checking for an integral exponent.

	* gcc.dg/builtins-14.c: New test case.

README 

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the file 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.html for how to report bugs usefully.
