From ebfa4877ea8fbbe5310a6251fcf10ab15178ec5b Mon Sep 17 00:00:00 2001 From: Jeongkeun Kim Date: Wed, 29 Apr 2026 11:21:31 +0900 Subject: [PATCH] Move vectorize_pred to test/correctness, fix failing_with_issue build Issue #3357 now passes. Rewrote the test to initialize f/g with cast(0) rather than undef so all positions are deterministic and the full output is compared. Widened to W = vec_width * 4, H = 1000 to cover more predicate-edge conditions. Update 3292 and 3293 to the current JITUserContext* allocator API (set_custom_allocator was removed). Add EXPECT_FAILURE so ctest treats the still-crashing tests as known failures. Comment out 4283 whose source file does not exist.
