* Consolidate copies of mp code in powerpcSiddhesh Poyarekar2013-03-087-221/+15
| | | | | Retain a single copy of the mp code in power4 instead of the two identical copies in powerpc32 and powerpc64.
* arm: Implement armv6 optimized string routinesRichard Henderson2013-03-078-0/+707
| | | | | | | | The strcpy and strchr (and related) functions are four times faster than the byte-by-byte default versions. The strlen function is twice as fast for long strings and 50% faster for short strings over the armv4 version.
* AARCH64: Use <bits/mman-linux.h>Andreas Jaeger2013-03-072-73/+8
| | | | | * sysdeps/unix/sysv/linux/aarch64/bits/mman.h: Remove all defines provided by bits/mman-linux.h and include <bits/mman-linux.h>.
* Install <bits/mman-linux.h>Andreas Jaeger2013-03-072-1/+7
| | | | | * sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Add bits/mman-linux.h.
* Merge powerpc slowexp.c into generic codeSiddhesh Poyarekar2013-03-076-133/+21
|
* Merge powerpc slowpow.c into generic codeSiddhesh Poyarekar2013-03-076-186/+29
|
* Use an intermediate variable to sum exponents in powerpc __mul and __sqrSiddhesh Poyarekar2013-03-073-10/+19
|
* Use generic mpa.c code for everything except __mul and __sqrSiddhesh Poyarekar2013-03-074-1256/+19
|
* Remove PIPE_BUF Linux-specific codeSiddhesh Poyarekar2013-03-076-28/+190
| | | | | | | | Fixes BZ #12723 The variable pipe buffer size does nothing to the value of PIPE_BUF, since the number of bytes that are atomically written is still PIPE_BUF on Linux.
* Revert " * sysdeps/x86_64/strlen.S: Replace with new SSE2 based implementation"Ondrej Bilka2013-03-0613-763/+1306
| | | | This reverts commit b79188d71716b6286866e06add976fe84100595e.
* * sysdeps/x86_64/strlen.S: Replace with new SSE2 based implementationOndrej Bilka2013-03-0613-1306/+763
| | | | | which is faster on all x86_64 architectures. Tested on AMD, Intel Nehalem, SNB, IVB.
* T_REMOVEDIR and AT_EACCESS have the same value.Patsy Franklin2013-03-062-0/+10
| | | | | Add comments to fcntl.h explaining why AT_REMOVEDIR and AT_EACCESS can have the same value.
* Use <bits/mman-linux.h> for MIPSAndreas Jaeger2013-03-064-73/+17
| | | | | | | | | * sysdeps/unix/sysv/linux/bits/mman-linux.h (MAP_ANONYMOUS): Allow definition via __MAP_ANONYMOUS. * sysdeps/unix/sysv/linux/mips/bits/mman.h: Remove all defines provided by bits/mman-linux.h and include <bits/mman-linux.h>. (__MAP_ANONYMOUS): Define.
* arm: Add optimized add_n and sub_nRichard Henderson2013-03-063-0/+88
| | | | | | | | Written from scratch rather than copied from GMP, due to LGPL 2.1 vs GPL 3, but tested with the GMP testsuite. This is 250% faster than the generic code as measured on Cortex-A15, and the same speed as GMP on the same core, and probably everywhere.
* arm: Add optimized submul_1Richard Henderson2013-03-062-0/+69
| | | | | | | | Written from scratch rather than copied from GMP, due to LGPL 2.1 vs GPL 3, but tested with the GMP testsuite. This is 50% faster than the generic code as measured on Cortex-A15. It is 25% slower than the current GMP routine on the same core.
* arm: Add optimized addmul_1Richard Henderson2013-03-062-0/+68
| | | | | | | | | Written from scratch rather than copied from GMP, due to LGPL 2.1 vs GPL 3, but tested with the GMP testsuite. This is 25% faster than the generic code as measured on Cortex-A15, and the same speed as GMP on the same core. It's probably slower than GMP on the A8 and A9 cores though.
* arm: Add optimized ffs for armv6t2Richard Henderson2013-03-063-0/+88
|
* arm: Implement hard-tp for GET_TLSRichard Henderson2013-03-064-11/+30
|
* arm: Tidy architecture selectionRichard Henderson2013-03-063-8/+45
|
* arm: Unless arm4t, pop return address directly into pcRichard Henderson2013-03-063-5/+14
|
* arm: Commonize BX conditionalsRichard Henderson2013-03-064-30/+21
| | | | Add BLX macro in addition and use it where appropriate.
* arm: Delete LOADREGS macroRichard Henderson2013-03-063-5/+4
| | | | | | There was only one user. It's "condition" argument was used for "ia" rather than an actual condition. The apcs26 syntax is almost certainly not needed, given current binutils requirements.
* arm: Use push/pop mnemonicsRichard Henderson2013-03-0620-134/+154
| | | | | | For arm this makes no difference--the result is bit-for-bit identical; for thumb this results in smaller encodings. Perhaps it ought not and this is in fact an assembler bug, but I also think it's clearer.
* arm: Enable thumb2 mode in assembly filesRichard Henderson2013-03-062-2/+14
| | | | | | The preceeding patches have allowed for the few incompatibilities between arm and thumb2 mode, or have marked the file as not wanting to use thumb2 mode.
* arm: Introduce and use GET_TLSRichard Henderson2013-03-0610-42/+77
| | | | | | Factor out the sequence needed to call kuser_get_tls, as we can't play subtract into pc games in thumb mode. Prepare for hard-tp, pulling the save of LR into the macro.
* arm: Introduce and use NEGOFF series of macrosRichard Henderson2013-03-066-14/+43
| | | | | | | | | There are several places in which we access negative offsets from the thread-pointer, but thumb2 only supports positive offsets in memory references. Avoid duplicating the rather large macros in which these references are embedded by abstracting out the operation.
* arm: Introduce and use LDST_PCRELRichard Henderson2013-03-065-24/+47
| | | | | Macro-ising the few instances where we need to distinguish between arm and thumb pc-relative memory operations.
* Remove MAP_GROWSUP on s390Andreas Jaeger2013-03-062-2/+3
| | | | | * sysdeps/unix/sysv/linux/s390/bits/mman.h (MAP_GROWSUP): Remove, it's not part of Linux headers.
