Danial Klimkin	9671ed1afc	Revert "LSV: forbid load-cycles when vectorizing; fix bug (#104815)" (#106245) ... This reverts commit c46b41aaa6eaa787f808738d14c61a2f8b6d839f. Multiple tests time out, either due to performance hit (see comment) or a cycle.	2024-08-27 18:45:22 +02:00
Ramkumar Ramachandra	c46b41aaa6	LSV: forbid load-cycles when vectorizing; fix bug (#104815) ... Forbid load-load cycles which would crash LoadStoreVectorizer when reordering instructions. Fixes #37865.	2024-08-22 11:37:19 +01:00
Ramkumar Ramachandra	fff78a51ee	LSV/test/AArch64: add missing lit.local.cfg; fix build (#102607) ... Follow up on 199d6f2 (LSV: document hang reported in #37865) to fix the build when omitting the AArch64 target. Add the missing lit.local.cfg.	2024-08-09 14:17:13 +01:00
Ramkumar Ramachandra	199d6f2c0c	LSV: document hang reported in #37865 (#102479) ... LoadStoreVectorizer hangs on certain examples, when its reorder function goes into a cycle. Detect this cycle and explicitly forbid it, using an assert, and document the resulting crash in a test-case under AArch64.	2024-08-09 11:34:09 +01:00
