2014-12-17	make the definition of _Complex_I explicitly complex	Rich Felker	-2/+2
	it's unclear whether compilers which provide pure imaginary types might produce a pure imaginary expression for 1.0fi. using 0.0f+1.0fi ensures that the result is explicitly complex and makes this obvious to human readers too.
2014-12-17	make the result of the cimag macro a non-lvalue	Rich Felker	-1/+1
	this change is not necessary but helps diagnose invalid code. based on patch by Jens Gustedt.
2014-12-17	fix definition of CMPLX macros in complex.h to work in constant expressions	Rich Felker	-3/+9
	based on patches by Jens Gustedt. these macros need to be usable in static initializers, and the old definitions were not. there is no portable way to provide correct definitions for these macros unless the compiler supports pure imaginary types. a portable definition is provided for this case even though there are presently no compilers that can use it. gcc and compatible compilers provide a builtin function that can be used, but clang fails to support this and instead requires a construct which is a constraint violation and which is only a constant expression as a clang-specific extension. since these macros are a namespace violation in pre-C11 profiles, and since no known pre-C11 compilers provide any way to define them correctly anyway, the definitions have been made conditional on C11.
2014-12-09	don't shadow functions with macros in C++	Bobby Bingham	-0/+2
	C++ programmers typically expect something like "::function(x,y)" to work and may be surprised to find that "(::function)(x,y)" is actually required due to the headers declaring a macro version of some standard functions. We already omit function-like macros for C++ in most cases where there is a real function available. This commit extends this to the remaining function-like macros which have a real function version.
2012-12-11	make CMPLX macros available in complex.h in non-c11 mode as well	Szabolcs Nagy	-2/+0

2012-11-13	complex: add C11 CMPLX macros and replace cpack with them	Szabolcs Nagy	-0/+9

2012-10-21	complex: make _Complex_I work with gcc -std=c99 -pedantic-errors	nsz	-0/+4

2012-03-22	simplify creal and cimag macros	Rich Felker	-8/+8

2012-03-22	add creal/cimag macros in complex.h (and use them in the functions defs)	Rich Felker	-0/+11

2012-03-13	first commit of the new libm!	Rich Felker	-0/+103
	thanks to the hard work of Szabolcs Nagy (nsz), identifying the best (from correctness and license standpoint) implementations from freebsd and openbsd and cleaning them up! musl should now fully support c99 float and long double math functions, and has near-complete complex math support. tgmath should also work (fully on gcc-compatible compilers, and mostly on any c99 compiler). based largely on commit 0376d44a890fea261506f1fc63833e7a686dca19 from nsz's libm git repo, with some additions (dummy versions of a few missing long double complex functions, etc.) by me. various cleanups still need to be made, including re-adding (if they're correct) some asm functions that were dropped.
