Richard,
I have a patch for PR50672.
When compiling the testcase from the PR with -ftree-tail-merge, the scenario is
as follows:
We start out tail_merge_optimize with blocks 14 and 20, which are alike, but not
equal, since they have different successors:
...

Hello,
by recent changes gcc begun to move code into the prologue region.
This is for x64 SEH an issue, as here the table-information for
prologue is limited to 255 bytes size. So we need to avoid moving
additional code into prologue. To achieve this we mark all standard
and xmm registers as
The problem is that the references to object C1 and C2 live in
a hash table, and that although the referenced nodes will be retained
by the garbage collector, their mapping in int_cst_hash_table is
deleted by the GC.
This isn't a simple hash table, is it?
I am not familiar with the details

I don't think that will fix this bug. The bug occurs if:
(1) The exclusive lock set has error_mark_node.
(2) The shared lock set has the actual lock.
In this case, remove_lock_from_lockset thinks that it has found the

I suppose technically the middle-end could be improved to implement
ashlmode as vashlmode by broadcasting the scalar, but Altivec
is the only extant SIMD ISA that would make use of this. All of
the others can
X86 backend doesn't accept the new expression as valid address while
(zero_extend:DI) works just fine. This patches keeps ZERO_EXTEND
when zero-extending address to Pmode. It reduces number of lea from
24173 to 21428 in x32 libgfortran.so. Does it make any senses?
I'd be inclined to have
The generic support for vector permutation will allow for automatic
lowering to V*QImode, so all we need to add to support for these targets
is the single V16QI pattern that represents the base permutation insn.
I'm not touching any of the other ways that the permutation insn
could be generated.
They weren't enabled for the Ada part of the front-end and the C part of the
library. Of course there are a few warnings...
Tested on i586-suse-linux, applied on the mainline.

The pph streamer does not write out expanded locations. It emits the
line map tables exactly as it found them on the initial compile so
that it can recreate them when the pph image is restored.
This allows it to emit the location_t as integers and produce the same
line locations than the

Ok, if I read the rtl correctly, you can perform a vector shift,
where each shift count comes from the corresponding element of op2.
But VIS has no vector shift where the shift count comes from a
single scalar
1. The placement of subreg in
(plus:DI (subreg:DI (mult:SI (reg/v:SI 85 [ i ])
(const_int 4 [0x4])) 0)
(subreg:DI (reg:SI 106) 0))
isn't supported by x86 backend.
That's easy to fix.
2. The biggest problem is optimizing mask 0x to
Nothing major to report. I found a small buglet in
gcc/testsuite/g++.dg/dg.exp that is left over from the memmodel -
simulate-thread rename.
I also found that trunk does not have the following change to
g++.dg/dg.exp and I will submit this as a follow up (to trunk).
Committed to branch.
Tests gcc.target/arm/pr48252.c and gcc.target/arm/neon-vset_lanes8.c
expect little-endian code and fail when compiled with -mbig-endian.
This patch skips the test if the current multilib does not generate
little-endian code.
I'm not able to run execution tests for -mbig-endian for GCC mainline

Ouch. I see this is not in, and I though I checked in the draft months
ago.
Please check this in immediately!!!
Done last evening, and made some further tweaks.
The pph branch also needs to stream struct function objects, but it
doesn't need to stream things like SSA names and the other data
processed by output_function/input_function.
This patch factors out the common code into separate functions. I've
made them static for now, since no other external

I don't think that will fix this bug. The bug occurs if:
(1) The exclusive lock set has error_mark_node.
(2) The shared lock set has the actual lock.
Oh, I see. This change looks fine for google/gcc-4_6, then.
