Set errno for log1p on pole/domain error.
According to bug 6792, errno is not set to ERANGE/EDOM by calling log1p/log1pf/log1pl with x = -1 or x < -1. This patch adds a wrapper which sets errno in those cases and returns the value of the existing __log1p function. The log1p is now an alias to the wrapper function instead of __log1p. The files in sysdeps are reflecting these changes. The ia64 implementation sets errno by itself, thus the wrapper-file is empty. The libm-test is adjusted for log1p-tests to check errno. [BZ #6792] * math/w_log1p.c: New file. * math/w_log1pf.c: Likewise. * math/w_log1pl.c: Likewise. * math/Makefile (libm-calls): Add w_log1p. * math/s_log1pl.c (log1pl): Remove weak_alias. * sysdeps/i386/fpu/s_log1p.S (log1p): Likewise. * sysdeps/i386/fpu/s_log1pf.S (log1pf): Likewise. * sysdeps/i386/fpu/s_log1pl.S (log1pl): Likewise. * sysdeps/x86_64/fpu/s_log1pl.S (log1pl): Likewise. * sysdeps/ieee754/dbl-64/s_log1p.c (log1p): Likewise.
