Re: [RFC, ARM] later split of symbol_refs

2012/6/30 Georg-Johann Lay g...@gcc.gnu.org: Is there a special reason to restrict it to SYMBOL_REF? Doesn't the same issue occur with, e.g. (const (plus (symbol_ref const_int))) or label_ref? Hi! We have added splits for symbol_ref plus const and label_ref. With this patch, assembly code and

Re: [PATCH][PING] Vectorize conversions directly

Here is the patch with iterators for instructions and neon_type attributes. Also fast-math-pr35982.c is changed according to Ira's comment. I will look at integration with patterns for neon intrinsics later. 2011-12-22 Dmitry Plotnikov dplotni...@ispras.ru gcc/ * tree-cfg.c
