This patch is for the google/gcc-4_7 branch. It's a backport of an
upstream patch at:
http://gcc.gnu.org/ml/gcc-patches/2012-08/msg00398.html
If approved for trunk, is this OK for google/gcc-4_7?
Google ref b/6705530.

This is a fix to prepare the xmlj_io.c file of gnu classpath to a coming

Basically, we were previously accessing fields inside the

that won't be possible anymore. Client code will have to use access

This adds a virual_operand_p predicate and uses it where we currently
use the bit on the decl (VAR_DECL_IS_VIRTUAL_OPERAND) directly.
I suspect most of the is_gimple_reg users in SSA optimizers can
be replaced by this predicate eventually making is_gimple_reg a
private predicate to the gimplifier
This splits out more cleanups from the main patch to make that smaller.
The only bigger part of the patch is making tree-stdarg track
escapes/varargs for SSA names more precise by not globbing on
SSA_NAME_VAR but instead using the bits [0..num_ssa_names-1] for
SSA names and [num_ssa_names,max_decl

Eh? Why's that? I think we should disentangle -mxop and -mfma4
instead. Otherwise,
Hello,
Bdver2 cpu supports both fma and fma4 instructions.
Previous to patch, option "-mno-xop" removes "-mfma4".
Similarly, option "-mno-fma4" removes "-mxop".
So, the patch conditionally disables "-mfma" or "-mfma4".
Enabling "-mxop" is done by also checking "-mfma".
Ok for trunk?

Hi,
I've just reverted my recent merge from upstream trunk on the aarch64-branch
(r190119).
A cleaner and broader merge will follow.
Thanks

Hi Richard,
Err - you are inside the compiler and should not use plugin stuff to
register your machine dependent pass.
Umm, OK, what is the correct method for registering target specific
passes ? (Ones that need to run at times other than
TARGET_MACHINE_DEPENDENT_REORG).
Cheers

Hi DJ,
I am applying the following patch to the gcc mainline as an obvious
fix for the following problem building the RL78 backend:
gcc/config/rl78/rl78.c:151:3: error: 'PASS_POS_INSERT_BEFORE' undeclared

Btw, if HOST_WIDE_INT == int the above won't even compile.

Hi all!
I'd like to ask whether stack-protector changes for Android could go to 4.7?
