Bug 17724 reports references to fesetround being brought in by ldbl-128ibm rintl via references to __rintl from __kernel_standard_l. Because all three __kernel_standard* functions are in the same file, this gets brought in even though only the long double version __kernel_standard_l needs __rintl, and the C90 functions use only __kernel_standard. This patch fixes this by splitting the three versions into separate files; it's fine for long double functions to refer to fe* functions directly, unless they get called by C90 double functions. Tested for x86_64 (testsuite; the reordering of code means disassembly of shared libraries can't usefully be compared). Tested for powerpc that the relevant issue disappears from the linknamespace test output. [BZ #17724] * sysdeps/ieee754/k_standard.c: Don't include <float.h>. (__kernel_standard_f): Remove. Moved to k_standardf.c. (__kernel_standard_l): Remove. Moved to k_standardl.c with (char *) casts added. * sysdeps/ieee754/k_standardf.c: New file. * sysdeps/ieee754/k_standardl.c: Likewise. * math/Makefile (libm-support): Remove k_standard. (libm-calls): Add k_standard.
