5 gcc/
6 * tree-vect-patterns.c (widened_name_p): Rename to ...
7 (type_conversion_p): ... this. Add new argument to determine
8 if it's a promotion or demotion operation. Check for
9 CONVERT_EXPR_CODE_P instead of NOP_EXPR.
10 (vect_recog_dot_prod_pattern): Call type_conversion_p instead
11 widened_name_p.
12 (vect_recog_widen_mult_pattern, vect_recog_widen_sum_pattern,
13 vect_operation_fits_smaller_type, vect_recog_widen_shift_pattern):
14 Likewise.
15 (vect_recog_mixed_size_cond_pattern): Likewise and allow
16 non-constant then and else clauses.
17
18 gcc/testsuite/
19 * gcc.dg/vect/bb-slp-cond-3.c: New test.
20 * gcc.dg/vect/bb-slp-cond-4.c: New test.

8 * expr.h (copy_blkmode_to_reg): Declare.
9 * expr.c (copy_blkmode_to_reg): New function.
10 (expand_assignment): Don't expand register RESULT_DECLs before
11 the lhs. Use copy_blkmode_to_reg to copy BLKmode values into a
12 RESULT_DECL register.
13 (expand_expr_real_1): Handle BLKmode decls when looking for promotion.
14 * stmt.c (expand_return): Move BLKmode-to-register code into
15 copy_blkmode_to_reg.
