How to access structure information from "pass_vectorize"
We are writing a GIMPLE pass and would like to use some information computed in pass_vectorize. However, we are not able to use the data structures which gets populated in pass_vectorize because the information is not made available across passes. In particular, we wish to access the structures "stmt_vec_info" and "data_reference". How do we access this information? Should we invoke pass_vectorize as a sub-pass of our pass? Should we explicitly call the execute function of pass_vectorize in our pass? Or should we modify pass_vectorize code and make a deep copy in a global variable? Is there any other way of getting this information?
bootstrap broken for '-O3'
High, since "trunk revision 206525" I'm unable to bootstrap gcc with '-O3' as optimisation. No problem until revision 2065250. >From the diff-output it looks like this entry from ChangeLog is the only candidate: --- diff -urN -x.svn gcc-head-206520/LAST_UPDATED gcc-head-206525/LAST_UPDATED --- gcc-head-206520/LAST_UPDATED2014-01-19 17:54:07.053340903 +0100 +++ gcc-head-206525/LAST_UPDATED2014-01-19 18:58:54.049008110 +0100 @@ -1,2 +1,2 @@ -Sun Jan 19 17:54:07 CET 2014 -Sun Jan 19 16:54:07 UTC 2014 (revision 206520) +Sun Jan 19 18:58:54 CET 2014 +Sun Jan 19 17:58:54 UTC 2014 (revision 206525) diff -urN -x.svn gcc-head-206520/gcc/ChangeLog gcc-head-206525/gcc/ChangeLog --- gcc-head-206520/gcc/ChangeLog 2014-01-19 17:54:03.620441749 +0100 +++ gcc-head-206525/gcc/ChangeLog 2014-01-19 18:58:51.113097157 +0100 @@ -1,3 +1,15 @@ +2014-01-10 Richard Biener + + PR tree-optimization/59374 + * tree-vect-slp.c (vect_slp_analyze_bb_1): Move dependence + checking after SLP discovery.

On the way I noticed (well, strictly speaking my editor did, and transparently so) that the MAINTAINERS file was ISO 8859, so I did the conversation to UTF-8 as well. It's 2014 after all. Gerald * MAINTAINERS: Convert to UTF-8. Properly sort Xinliang David Li's entry.
