tilegx: small performance fix for string routines We were multiplying a byte by 0x0101010101010101ULL to create a constant for SIMD ops, but the compiler isn't good at optimizing this case (the fact that one operand is a byte is lost by the time it would be possible to do the optimization). So instead we add a helper routine that explicitly uses SIMD ops to create the constant.

2012-05-12 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/tilegx/memchr.c: Use new copy_byte() function
to efficiently generate a large constant for masking.
* sysdeps/tile/tilegx/memset.c: Likewise.
* sysdeps/tile/tilegx/rawmemchr.c: Likewise.
* sysdeps/tile/tilegx/strchr.c: Likewise.
* sysdeps/tile/tilegx/strchrnul.c: Likewise.
* sysdeps/tile/tilegx/strrchr.c: Likewise.
* sysdeps/tile/tilegx/string-endian.h (copy_byte): New function.
tile: allow memcpy(p, p, n) without corrupting memory at "p" Although this is not required by the definition of memcpy(), in practice this sort of thing does happen, and it's easy to make the code robust by doing nothing in this case. (Since structure copy causes the compiler to emit a memcpy, in the case where the target structure is the same as the destination, we were seeing corruption.)

2012-05-12 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/tilegx/memcpy.c: Allow memcpy(p, p, n)
without corrupting memory at "p".
tile: avoid using _LP64 The convention is to use __WORDSIZE everywhere. I happened to notice that we weren't doing this in __tls_get_addr.S.
2012-05-12 04:53:19 +08:00
2012-05-12 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/__tls_get_addr.S: Use __WORDSIZE, not _LP64.
tile: support stackguard-macros.h header
2012-05-12 04:11:04 +08:00
2012-05-12 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/stackguard-macros.h: New file.
* sysdeps/tile/elf/stackguard-macros.h: New stub include file.
tile: remove stale #define of ELF_MACHINE_PLTREL_OVERLAP
2012-05-12 03:42:04 +08:00
2012-05-12 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/Makefile (ELF_MACHINE_PLTREL_OVERLAP):
Remove variable no longer used by core.
tile: update pthread_attr_t and struct siginfo names This adds a tag to the pthread_attr_t underlying type so we can forward-declare it, and removes the siginfo_t type, to match changes in the main tree.
2012-05-12 02:42:46 +08:00
2012-05-12 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/unix/sysv/linux/tile/bits/siginfo.h: Don't name
siginfo_t struct. Add forward declaration of pthread_attr_t and
use it in sigevent.
* sysdeps/unix/sysv/linux/tile/nptl/bits/pthreadtypes.h: Name
pthread_attr_t union.
tile: Remove elf/ and create crti.S/crtn.S This patches fixes up the tile startup files, moving elf/start.S up a directory level and implementing the required crti.S and crtn.S files based on the old initfini.c compiler output (hand-optimized to bum a couple of cycles).
2012-05-12 02:27:57 +08:00
2012-05-12 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/crti.S: New file, based on compiler output
for sysdeps/generic/initfini.c.
* sysdeps/tile/crtn.S: Likewise.
* sysdeps/tile/Makefile (CFLAGS-initfini.s): Remove variable.
* sysdeps/unix/sysv/linux/tile/nptl/Makefile
(CFLAGS-pt-initfini.s): Likewise.
* sysdeps/tile/elf/start.S: Moved to ...
* sysdeps/tile/start.S: ...here.
tile: update _itoa.h include path Common code moved _itoa.h necessitating a change in the #include path. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-04-15 09:10:30 +08:00
2012-04-15 Mike Frysinger <vapier@gentoo.org>
* sysdeps/unix/sysv/linux/tile/tilegx/register-dump.h: Include
<_itoa.h> instead of <stdio-common/_itoa.h>.
* sysdeps/unix/sysv/linux/tile/tilepro/register-dump.h: Likewise.
Use include_next to chain math_private.h headers.
2012-03-10 08:28:42 +08:00
2012-03-09 Richard Henderson <rth@twiddle.net>
* sysdeps/tile/math_private.h: Use include_next to
chain math_private.h.

2012-03-10 07:56:38 +08:00
2012-03-09 Paul Eggert <eggert@cs.ucla.edu>
[BZ #13673]
Replace FSF snail mail address with URLs, as per GNU coding standards.
tile: use const instead of __const.
2012-02-01 00:46:09 +08:00
2012-01-31 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/bits/fenv.h: Use const instead of __const.
* sysdeps/unix/sysv/linux/tile/sys/cachectl.h: Likewise.
tile: use <feedback.h> instead of <feedback-asm.h> in sysdep.h.
2012-02-01 00:26:00 +08:00
2012-01-31 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/sysdep.h: Use <feedback.h> not <feedback-asm.h>
to reflect change from gcc community giveback.
tile: Ignore feraiseexcept() internally.
2012-01-31 21:59:30 +08:00
2012-01-31 Chris Metcalf <cmetcalf@tilera.com>
* sysdeps/tile/math_private.h: Ignore feraiseexcept() internally.
Don't check HAVE_ELF or NO_UNDERSCORES in sysdeps/tile/sysdep.h.
2012-01-31 01:43:25 +08:00
2012-01-30 Chris Metcalf <cmetcalf@tilera.com>
