The ia64_rse_is_rnat_slot func expects an unsigned pointer, but we're
passing in a signed pointer. The signness doesn't matter here, so
convert it to unsigned.

The recent change to clean up these defines missed the ia64 logic.
Update it accordingly.

This patch removes redudant definition from PowerPC specific
math_ldbl, using the definitions from ieee754 math_ldbl.h.
|
|
Retain a single copy of the mp code in power4 instead of the two
identical copies in powerpc32 and powerpc64.
|
|
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.

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.

This reverts commit b79188d71716b6286866e06add976fe84100595e.

which is faster on all x86_64 architectures.
Tested on AMD, Intel Nehalem, SNB, IVB.

Add comments to fcntl.h explaining why AT_REMOVEDIR
and AT_EACCESS can have the same value.

* 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.

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.

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.

than GMP on the A8 and A9 cores though.

Add BLX macro in addition and use it where appropriate.
|
|
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.

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.
|
|
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.
|
|
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.
|
|
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.
|
|
Macro-ising the few instances where we need to distinguish between
arm and thumb pc-relative memory operations.

* sysdeps/unix/sysv/linux/s390/bits/mman.h (MAP_GROWSUP):
Remove, it's not part of Linux headers.
