*	work around regression building for armhf with clang (compiler bug)	Rich Felker	2016-02-19	1	-1/+1
\| \| \| \| \| \| \| \| \|	commit e4355bd6bec89688e8c739cd7b4c76e675643dca moved the math asm from external source files to inline asm, but unfortunately, all current releases of clang use the wrong inline asm constraint codes for float and double ("w" and "P" instead of "t" and "w", respectively). this patch adds detection for the bug in configure, and, for now, just disables the affected asm on broken clang versions.
*	replace armhf math asm source files with inline asm	Rich Felker	2016-01-20	1	-0/+15
	this makes it possible to inline them with LTO, and is the simplest approach to eliminating the use of .sub files. this also makes VFP sqrt available for use with the standard EABI (plain arm rather than armhf subarch) when libc is built with -mfloat-abi=softfp. the same could have been done for fabs, but when the argument and return value are in integer registers, moving to VFP registers and back is almost certainly more costly than a simple integer operation.
