The goal of this series is to avoid the creation of orphaned OP_PHISRCs by simplify_loads() when it appears that the loads con't be simplified afterall but that some OP_PHISRC have already been created. This change then lead to some code restructuration and simplification. This series is available at: git://github.com/lucvoo/sparse.git fix-orphaned-phisrc based on commits (a merge) ac6c25bc066eab36942539ba11c7ab6cf0c63674 (bool-context) ecda2093f19088fa94c3a4ac85359c6d0f1c64af (fix-cond-address) fc981fe285c37ee297e93ef1cc8725caac75f9b3 (fix-bitfield-init-v2) up to commit: 8b6716908788dfd1713215e7d4ddaa4f3d341948 Luc Van Oostenryck (8): extract add_dominator() from find_dominating_parents() add helper add_load_dominators() remove test on initial phi->ident avoid phisrc orphaned by simplify_loads() avoid phisrc orphaned by find_dominating_stores() integrate add_load_dominators() into rewrite_load_instruction() check duplicated phi-nodes directly on dominators avoid creating unneeded phi-sources flow.c | 79 +++++++++++++++++++++++------------- flow.h | 2 +- memops.c | 14 ++----- validation/linear/phisrc-orphan-ld.c | 22 ++++++++++ validation/linear/phisrc-orphan-st.c | 17 ++++++++ validation/loop-linearization.c | 30 +++++++------- 6 files changed, 110 insertions(+), 54 deletions(-) create mode 100644 validation/linear/phisrc-orphan-ld.c create mode 100644 validation/linear/phisrc-orphan-st.c -- 2.12.0 -- To unsubscribe from this list: send the line "unsubscribe linux-sparse" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
