* math: Import isinf and others to global namespacePierre Moreau2016-04-181-0/+23
| | | | | | | | | | | | | | | | | | | Starting from C++11, several math functions, like isinf, moved into the std namespace. Since cmath undefines those functions before redefining them inside the namespace, and glibc 2.23 defines the C variants as macros, the C variants in global namespace are not accessible any longer. v2: Move the fix outside of Nouveau, as suggested by Jose Fonseca, since anyone might need it when GCC switches to C++14 by default with GCC 6.0. v3: * Put the code directly inside c99_math.h rather than creating a new header file, as asked by Jose Fonseca; * Guard the code behind glibc version checks, as only glibc > =2.23 defines isinf & co. as functions, as suggested by Jose Fonseca.

* gallium: fix gcc compile errors when using _XOPEN_SOURCE=600 but not std=c99Jose Fonseca2015-04-031-1/+6
| | | | | | The fpclassify stuff either needs std=c99 or _XOPEN_SOURCE=600 passed to gcc, but when using the latter the lrint family of function will be defined too.
* c99_math: Don't reimplement lrint and friends on MSVC 2013.Jose Fonseca2015-03-251-1/+2
| | | | | | | | MSVC 2013 declares these functions, both for C and C++ source files. This was caught with MSVC in analyze mode. Reviewed-by: Brian Paul <brianp@vmware.com>

* include,auxiliary: Remove support for MSVC older then 2008.Jose Fonseca2015-02-261-71/+0
| | | | | | | | | | MSVC 2008 (shipped with Windows SDK 7.0.7600) is the oldest we need to support. At least on llvmpipe, gallium/auxiliary, and util modules. For the remaining modules (particular all OpenGL specific code) can be built with MSVC 2013. Reviewed-by: Brian Paul <brianp@vmware.com> Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com>

The alternative would be to include math.h in c99_compat.h but that seems heavy-handed. This patch also replaces INLINE with inline in the c99 math function wrappers. Fixes MSVC build. Acked-by: Matt Turner <mattst88@gmail.com>
