This reduces compile-time of the testcase in PR56113 (with n = 4)
from 575s to 353s. It does so by reducing the quadratic algorithm
to impose an order on visiting dominator sons during a domwalk.

the CFG during the walk and t

This reduces the work done for single predecessor nodes for
assigning pointer equivalence classes in label_visit. For
the PR56113 testcase with n = 4 this reduces PTA time from
tree PTA: 119.59 (34%) usr
to
tree PTA: 51.62 (18%) usr

The mode for AND should really be CC_NZ, so I fixed that up and in the TST
patterns that (erroneously) expected it to be CC mode.
It has been tested on linux and bare-metal.
OK to commit to trunk (as bug fix)?
Thanks.

Hi All,
This is simple fix that is aimed to help users in porting their
applications to x86 platforms which rely on an order of function
argument evaluation. To preserve direct order of argument evaluation
they need to be added additional option '-mno-push-args' to compile
that looks reasonable pr
So - back to PR55848 - this testcase shows that we still handle
builtins vs. non-builtins in a wrong way. If at compile-time
we chose to use a non-builtin variant we have to preserve that
(-fno-builtin) - easy to do at WPA stage by adjusting symbol
merging. Now, at LTRANS stage somebody clever d

AIX 6.1 added an alignment argument to the .lcomm pseudo-op. This

Richard Stallman has given permission to include code derived from GNU
C Library in libgcc for AIX using the GCC Runtime Exception license.
The updated patch is appended. The GNU C Library code (cxa_atexit.c,
cxa_finalize.c, exit.h) is modified, so I am not exactly certain if my

Hi,
This patch moves the various tuning parameter data structures
further up config/aarch64/aarch64.c and then uses them to
initialise the generic_tunings variable. This mirrors their
position on trunk.
This fixes the warning:

Hi,
This patch series fixes a number of warnings in the AArch64 port on
the aarch64-4.7-branch.
The warnings fixed are:

Hi,
In config/aarch64/aarch64.c::aarch64_add_constant `shift' was
declared after we started writing code. C90 doesn't like this,
so split the declaration and the assignment.

Hi,
push_reload takes an `enum reload_type' as its final argument.
On trunk we just cast the int we have to the correct type,
so we do that here to mirror trunk and correct the warning.
We can't fix this by changing the type of the argument we take
as we would then need to forward declare the en

When I did the initial power7 port, I punted on allowing TImode in the VSX
