Hi!
I want to uninline some basic blocks to a separate function to aid slp
vectorization.
The new pass runs just before the slp vectorization pass.
As a first try I create an new and empty function.
Which in turn will be filled with some copies of basic blocks from the original
function.
As an e
Thank you for the hint. I managed to extract the basic blocks to a helper
function and put
a call to this helper function at the place of the removed basic blocks in the
original function.
All this is done with help of move_sese_region_to_fn.
The helper function is created similar to create_omp_c
(Sorry for the duplicate.)
I managed to pass the needed parameters to the generated function.
However I cannot pin down the reason why the compilation fails.
It seems that the cfg is somehow broken, but I cannot tell how.
Do you have any debugging hints?
As far as I can tell, the cfg is changed d

am a little confused by that, since comdats does not change anything.
But maybe there is no connection between the violated assertion and the
vanishing function.

Ah, now I get it.
So the reason is that comdats is the last ipa pass that is run.
I continue to look for the problem in purge_dead_edges.
Thank you for the explanation.
Best regards,

Hello everybody,
I want to make a copy of a loop, but it seems that the function duplicate_loop
does not work the way I need it.
It does not copy basic_blocks and edges.
What I need is this transformation
// Original
int foo () {
int i, b;
i = 0;
b = 50;
for (; i <= b; ++b) {
LOOP_B
Hi,
I have problems compiling xalan as part of spec2006 benchmark for aarch64, both
native and cross.
The issue arises when both -flto and -fprofile-generate are enabled during LTO.
Compiling with the same flags for x86 has no problem.
Also other projects for aarch64 compile with -flto and -fprof
Compiling with -flto-partition=none succeeds,
however increases compilation time significantly.
One interesting thing is that even the failed compile
produces an executable that works. Is that normal?
Should I really attach the ipa-cgraph dump to the bug report?
The file is 945M big, 27M compress
Hi,
I have a problem with a transformation pass I wrote.
The pass is meant to pipeline and unroll lookups in linked lists.
After my pass is run, gcc renames a variable, which leads to wrong results.
Part of my pass's dump, which is as I want it.

:
list_38 = list_10->next;
_22 = list_10
