- Subject: [PATCH] Fix ICE in vectorization dump (PR tree-optimization/55995)
This patch fixes an ICE in vectorization dump when section anchors are present.
Bootstrapped/tested on x86_64 and PPC 64 and found no new failures. OK
for trunk?
Thanks,
Sharad

* dumpfile.c (dump_loc): Print location only if available.
* testsuite/gcc.dg/vect/vect.exp: Use "details" flags for dump info.
* tree-vectorizer.c (increase_alignment): Intialize vect_location.
