New Revision: 151276
URL: http://llvm.org/viewvc/llvm-project?rev=151276&view=rev
Log:
* tgmath_logb.patch implements the missing logb function (see C99 standard
7.22, paragraph 5). * tgmath_fabs_complex.patch corrects the return types for
the complex fabs functions. These must be non-complex float/double/long double
(see C99 standard 7.22, paragraph 4 and 7.3.8.1). Patch contributed by Kristof
Beyls.
