2013-03-26Make mantissa type of mp_no configurableSiddhesh Poyarekar
The mantissa of mp_no is intended to take only integral values. This is a relatively good choice for powerpc due to its 4 fpus, but not for other architectures, which suffer due to this choice. This change makes the default mantissa a long integer and allows powerpc to override it. Additionally, some operations have been optimized for integer manipulation, resulting in a significant improvement in performance.
2013-03-26PowerPC: fix libm ABI issue for llroundlAdhemerval Zanella
2013-03-22Update sparc ULPs.David S. Miller
* sysdeps/sparc/fpu/libm-test-ulps: Update.
2013-03-22BZ#13889: expl (709.75) wrongly overflows for ldbl-128ibmAdhemerval Zanella
The patch increase the high value to check if expl overflows. Current high mark value is not really correct, the algorithm accepts high values. It also adds a correct wrapper function to check for overflow and underflow.
2013-03-22BZ#11120: fix x86_64/strcmp.S NOT_IN_libc safeguardsDmitry V. Levin
Due to a typo repeated several times, this bug hasn't been fixed yet, despite being marked as resolved in glibc 2.12. * sysdeps/x86_64/strcmp.S: Replace all occurrences of NOT_IN_lib with NOT_IN_libc.
