 LP 1010826

 Backport from mainline:

 gcc/
 PR tree-optimization/53729
 PR tree-optimization/53636
 * tree-vect-slp.c (vect_slp_analyze_bb_1): Delay call to
 vect_verify_datarefs_alignment until after statements have
 been marked as relevant/irrelevant.
 * tree-vect-data-refs.c (vect_verify_datarefs_alignment):
 Skip irrelevant statements.
 (vect_enhance_data_refs_alignment): Use STMT_VINFO_RELEVANT_P
 instead of STMT_VINFO_RELEVANT.
 (vect_get_data_access_cost): Do not check for supportable
 alignment before calling vect_get_load_cost/vect_get_store_cost.
 * tree-vect-stmts.c (vect_get_store_cost): Do not abort when
 handling unsupported alignment.
 (vect_get_load_cost): Likewise.

 gcc/
 PR tree-optimization/53636
 * tree-vect-data-refs.c (vect_compute_data_ref_alignment): Verify
 stride when doing basic-block vectorization.

 gcc/testsuite/
 PR tree-optimization/53636
 * gcc.target/arm/pr53636.c: New test.

2012-06-28 Ramana Radhakrishnan <email address hidden>

 gcc/
 * config/arm/arm.c (neon_dereference_pointer): Fixup typos.

 gcc/testsuite/
 * gcc.target/arm/lp101329.c: Remove unneeded comment.

2012-06-21 Ramana Radhakrishnan <email address hidden>

 LP 1013209
 gcc/
 * config/arm/arm.c (neon_dereference_pointer): Use fold_convert
 to convert expression to the right type. This is a Linaro 4.6 only
 patch as this was originally backported from FSF 4.7 and hence applies
 only here.

 gcc/testsuite/
 * gcc.target/arm/lp101329.c: New test.
