I only see this failure on power 7 for 64 bit. Power 7 has some limitations on
vectors that may require the failing parts of the tests to be skipped there.

The test case could be updated. The patch supports calculating the number of iterations for the special condition(step to min/max), so we may just update to the case to check if the "number of iterations" is there. like: diff --git a/gcc/testsuite/gcc.dg/vect/pr101145_3.c b/gcc/testsuite/gcc.dg/vect/pr101145_3.c index 99289afec0b..819e134c6e6 100644 --- a/gcc/testsuite/gcc.dg/vect/pr101145_3.c +++ b/gcc/testsuite/gcc.dg/vect/pr101145_3.c @@ -10,4 +10,4 @@ #include "pr101145.inc" -/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 2 "vect" } } */ +/* { dg-final { scan-tree-dump-times "Symbolic number of iterations is" 2 "vect" } } */ ^ permalink raw reply [flat|nested] 5+ messages in thread
