Hi!
This is an updated version of the get_bit_range fix, this time it
ensures that bitpos is not negative already right after the
get_inner_reference call, because various parts of the expansion might be
confused by the negative values. As the second testcase shows, even with
non-negative bitpos

Following on from:
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg00092.html
it looks like I'll have to "fix" the doloop_begin/end interface after all.
The current code goes on to do some rtx arithmetic on invalid CONST_INTs.
(FWIW, the arithmetic seems unnecessary and I think we could simply d

Hi,

Just one more thought on the design.
If you want to have at least a chance to survive something like:
dd if=/dev/zero of=test.c bs=10240 count=1000
gcc -Wall test.c
Then you should change the implementation of read_line to
_not_ returning something like 100GB of zeros

It is a different failure. There are 3 problems:
1. Hard coded 64-bit registers for pointers in x86-64 asm statements.
2. Treat WORD_SIZE == 32 as ia32 for machine state on x86-64.
3. On x86-64, assume ia32 FS system calls when LP64 is false.

It seems that splitting multi-word insns before reload results in
slightly better code on average (according to CSiBE). The attached
patch implements that.

internal_syscall casts pointers to uint64. It doesn't work for x32 since
32-bit pointers are signed extended to int64. This patch casts pointers
to uptr first. Tested with x32, x86-64 and x86. Please install it.

We need to allcate 2 64-bit integers to restore fn and arg with pop,
which only pop 64-bit integer into 64-bit register. Also pointers
are 32-bit for x32. This patch properly loads r8/r10 fpr syscall.
Please install it.
Thanks.

Hi,
The attached patch adds a w -> w constraint to vec_set.
Tested on aarch64-none-elf and aarch64_be-none-elf. OK for trunk?
Thanks,
Tejas Belagod
ARM.
Changelog:

gcc/
* config/aarch64/aarch64-simd.md (vec_set): Add w -> w option to
the constraint
x32 uses the same file system calls as x86-64. This patch fixes it
for x32. Tested on x32, x86-64 and x86. Please install it.
Thanks.

X32 uses the same FPU state as x86-64. Please install it. Thanks.

This fixes PR58492 - when late IPA passes are run all IPA transforms
are applied and the last fixup-cfg is run. This breaks the IL
when for example late local-pure-const makes changes that are not
fixed up for in the callers.
Bootstrap and tests running on x86_64-unknown-linux-gnu.

Hi Kostya,
As an aside, all of these asan tests have failed on
powerpc64le-unknown-linux-gnu since we began testing that target. I
have not yet had time to investigate why. Do you think there may be an
implicit or explicit assumption anywhere that PowerPC64 is big endian?
This is generally not s

This fixes the wrong direction of dependence edges in loop
distribution (this happens when you think that if you choose
the wrong direction a testcase will trip and thus you don't
think hard enough ...).
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

I'd like to add a new experimental optimization to the trunk. This
optimization was discussed on RA BOF of this summer GNU Cauldron.
It is a register pressure relief through live-range shrinkage. It
is implemented on the scheduler base and uses register-pressure insn

I've applied this further patch to C11-atomic branch to ensure that
the c11-atomic-exec-5.c test is only run where floating-point
exceptions are actually supported, to avoid spurious failures for
soft-float configurations (or any systems that have pthreads but not
).

I'm attaching a patch which allows gengtype to handle GTY-marked structs
that have no fields. These are useful for supporting the "have a
subclass for every gimple code" idea from:

Hello!
Attached patch enables soft-float multilibs for x86-32 RTEMS. The
patch activates SFmode and DFmode soft-float support routines. The
XFmode is mapped to DFmode due to lack of XFmode support in
soft-float. We already disable FPU return registers for -mno-80387, so
ABI is already changed for

Those functions are not referencing each other, but they get used in
different logical groups, so at least control granularity can be
improved. For instance,
1) all gcov user interfaces such as gcov_dump, gcov_flush, gcov_reset
are either not used at all, or all of them are used -- there is no
need
