2011-12-29PowerPC - Optimization for str[n]casecmp functionsAdhemerval Zanella
This patch provides throughput boost for the strcasecmp function (25% on ppc32 and 40% on ppc64) and strncasecmp (15% on both ppc32 and ppc64) for POWER7. The optimization is done by manually (strcasecmp) or automatically (strncasecmp) unrolling the test loop to avoid CPU stalls caused by a test followed by a load.
2011-12-29PowerPC - Optimization for nearbyint[f]Adhemerval Zanella
This patch provides throughput boost for the nearbyint[f] functions for POWER. For POWER7, it improves performance for nearbyintf from 5 (ppc32) to 6 times (ppc64) and for nearbyint from 2.5 up to 5 times. For POWER6 it improves nearbyintf up to 2x (ppc64) and nearbyint up to 4x.

2011-12-29PowerPC: Arithmetic function optimizations for POWERAdhemerval Zanella
This patch creates inline assembly functions that use intrinsic PPC floating point instructions when the platform supports them but rely on the internal GLIBC functions when the instructions are not implemented (for instance, on POWER4).
2011-12-29Optimize libmUlrich Drepper
libm is now somewhat integrated with gcc's -ffinite-math-only option and lots of the wrapper functions have been optimized. Backport of commit #0ac5ae2335292908f39031b1ea9fe8edce433c0f
2011-12-29Fix PLT uses in libm on powerpcAndreas Schwab

2011-08-19Fix profiling on powerpc32 secure-plt shared libs and PIEsAlan Modra
This patch moves the ppc32 _mcount to libc_shared.a, fixing a long-standing bug with profiling of secure-plt shared libraries and PIEs. The problem is that a ppc32 PIC PLT call stub uses r30 (GOT pointer) to load the function address from the PLT, r30 being set up in the function prologue, but _mcount is called before the function prologue. So chances are good that r30 will be pointing to the executable GOT when trying to call _mcount in a shared lib function. A similar problem can occur in a PIE if a shared lib calls a function in the executable.
2011-08-19Check for finite/infinity parms in IBM Long Double 128 fmal( )Dave Flaherty
This patch addresses some IBM Long Double 128 fmal () test-ldouble.out and test-ildoubl.out failures. If the ‘x’ and ‘y’ parameters are finite values and ‘z’ is infinity, the result of fmal () should be ‘z’ not NaN.
2011-08-18Provide a throughput boost to the 64-bit power7 strncmp code of approxWill Schmidt
15%. The 32-bit throughput is not notably affected by this change, so the change to the 32-bit code is done to keep the two files in sync with each other.
2011-08-18Trigonometric optimizations for POWER cpusAdhemerval Zanella
These POWER optimizations remove most of the FP->INT conversions in hypot/hypotf and sinf/cosf on POWER making the computation done with FP operations instead. This eliminates Load-Hit-Store (LHS) stalls, increasing performance of hypot/hypotf (by about 100% on POWER7 and 12% on POWER6) and sinf/cosf (by 80% on POWER7 and 30% on POWER6).

2011-05-03 Ryan S. Arnold <rsa@us.ibm.com> * elf/dynamic-link.h (elf_get_dynamic_info): Remove assert() around DT_RUNPATH and DT_RPATH which prevents running a dynamic linker with an embedded RPATH flag, which is what a compiler modified to embed a non-default INTERP section would do.
