* Use x constraints for operands to vfmaddss and vfmaddsdPeter Collingbourne2013-05-151-0/+4
| | | | | | | | | | | | | | | While these instructions accept memory operands, only one operand may be a memory operand. Giving two operands xm constraints gives the compiler the option of using memory for both operands, which would result in invalid assembly code. Using x for all operands is more appropriate, as most x86_64 calling conventions will pass the arguments in registers anyway. 2013-05-15 Peter Collingbourne <pcc@google.com> * sysdeps/x86_64/fpu/multiarch/s_fma.c (__fma_fma4): Replace xm constraints with x constraints. * sysdeps/x86_64/fpu/multiarch/s_fmaf.c (__fmaf_fma4): Likewise.
* Move _obstack_compat out of commonPeter Collingbourne2013-05-151-0/+4
| | | | | | | | | | | | | it is impossible to create an alias of a common symbol (as compat_symbol does), because common symbols do not have a section or an offset until linked. GNU as tolerates aliases of common symbols by simply creating another common symbol, but other assemblers (notably LLVM's integrated assembler) are less tolerant. 2013-05-15 Peter Collingbourne <pcc@google.com> * malloc/obstack.c (_obstack_compat): Add initializer. -

| | | | | | | | | | 2013-05-15 Edjunior Machado <emachado@linux.vnet.ibm.com> * sysdeps/unix/sysv/linux/s390/bits/siginfo.h (siginfo_t): Remove si_trapno and add si_addr_lsb to _sifields.sigfault. (si_trapno): Remove macro. (si_addr_lsb): Define new macro. (BUS_MCEERR_AR, BUS_MCEERR_AO): Define new values.

* Add comments to vDSO hwcap loading process.Carlos O'Donell2013-05-141-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Loading of the vDSO pseudo-hwcap from the type 2 GNU note is a rather arcane and poorly documented process. Given that I had a chance to review this code today I thought I would add all of the things I had to lookup to verify the validity of the process. With a single .note.GNU the vDSO can register up to 64 flags, though in practice you are limited to 64 - _DL_FIRST_EXTRA bits which on x86 is 12 bits. The only use of this that I know of is in the Xen support in Linux where they use the 1st bit to indicate "nosegneg". I see "We use bit 1 to avoid bugs in some versions of glibc when bit 0 is used; the choice is otherwise arbitrary.", but no reference to a glibc bug anywhere. The code as-is should support bit zero, so we still have that free for future use. The kernel, glibc, and ld.so.cache must coordinate to ensure that bit values don't go too high and are used consistently. --- 2013-05-13 Carlos O'Donell <carlos@redhat.com> * elf/dl-hwcaps.c (_dl_important_hwcaps): Comment vDSO hwcap loading. * elf/ldconfig.c (is_hwcap_platform): Comment each hwcap check. (main): Comment "tls" pseudo-hwcap.

* Define decimal constant M_1_DIV_El in libm-test.incAdhemerval Zanella2013-05-131-0/+5
| | | | This patch replaces the 1.0 / M_El by the decimal constant M_1_DIV_El.
* Use HP_TIMING for benchmarks if availableSiddhesh Poyarekar2013-05-131-0/+7
| | | | | | | | | | | | | HP_TIMING uses native timestamping instructions if available, thus greatly reducing the overhead of recording start and end times for function calls. For architectures that don't have HP_TIMING available, we fall back to the clock_gettime bits. One may also override this by invoking the benchmark as follows: make USE_CLOCK_GETTIME=1 bench and get the benchmark results using clock_gettime. One has to do `make bench-clean` to ensure that the benchmark programs are rebuilt.
* Make _LIB_VERSION a weak symbolSiddhesh Poyarekar2013-05-131-0/+7
| | | | | | | That way it can live alongside _LIB_VERSION in libieee.a for statically compiled programs. Resolves #14582.

* Add more comments to dlclose() algorithm.Carlos O'Donell2013-05-091-0/+4
| | | | | | | | | | | | | | The algorithm for scanning dependencies upon dlclose is less than immediately obvious. This patch adds two bits of comments that explain why you start the dependency search at l_initfini[1], and why you need to restart the search. --- 2013-05-09 Carlos O'Donell <carlos@redhat.com> * elf/dl-close.c (_dl_close_worker): Add comments.
