--- Comment #6 from Ulrich Weigand <uweigand at gcc dot gnu.org> 2012-05-04 14:56:52 UTC --- Author: uweigand Date: Fri May 4 14:56:48 2012 New Revision: 187162 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=187162 Log: 2012-05-04 Ulrich Weigand <ulrich.weig...@linaro.org> Backport from mainline: 2012-05-04 Ulrich Weigand <ulrich.weig...@linaro.org> PR tree-optimization/52633 * tree-vect-patterns.c (vect_vect_recog_func_ptrs): Swap order of vect_recog_widen_shift_pattern and vect_recog_over_widening_pattern. (vect_recog_over_widening_pattern): Remove handling of code that was already detected as over-widening pattern. Remove special handling of "unsigned" cases. Instead, support general case of conversion of the shift result to another type. 2012-05-04 Ulrich Weigand <ulrich.weig...@linaro.org> * tree-vect-patterns.c (vect_single_imm_use): New function. (vect_recog_widen_mult_pattern): Use it instead of open-coding loop. (vect_recog_over_widening_pattern): Likewise. (vect_recog_widen_shift_pattern): Likewise. 2012-04-10 Ulrich Weigand <ulrich.weig...@linaro.org> PR tree-optimization/52870 * tree-vect-patterns.c (vect_recog_widen_mult_pattern): Verify that presumed pattern statement is within the same loop or basic block. 2012-05-04 Ulrich Weigand <ulrich.weig...@linaro.org> Backport from mainline: 2012-05-04 Ulrich Weigand <ulrich.weig...@linaro.org> PR tree-optimization/52633 * gcc.dg/vect/vect-over-widen-1.c: Two patterns should now be recognized as widening shifts instead of over-widening. * gcc.dg/vect/vect-over-widen-1-big-array.c: Likewise. * gcc.dg/vect/vect-over-widen-4.c: Likewise. * gcc.dg/vect/vect-over-widen-4-big-array.c: Likewise. * gcc.target/arm/pr52633.c: New test. 2012-04-10 Ulrich Weigand <ulrich.weig...@linaro.org> PR tree-optimization/52870 * gcc.dg/vect/pr52870.c: New test.
