2022-06-30Avoid computing RPO for update_ssaRichard Biener1-2/+3
At some point when domwalk got the ability to use RPO for ordering dominator children we carefully avoided update_ssa eating the cost of RPO compute. Unfortunately some later consolidation of CTORs lost this again so the following makes this explicit via a special value to the bb_index_to_rpo argument of domwalk, speeding up update_ssa again. * domwalk.h (dom_walker::dom_walker): Update comment to reflect reality and new special argument value for bb_index_to_rpo. * domwalk.cc (dom_walker::dom_walker): Recognize -1 bb_index_to_rpo. * tree-into-ssa.cc (rewrite_update_dom_walker::rewrite_update_dom_walker): Tell dom_walker to not use RPO.

2018-01-23-Warray-bounds: Fix false positive in some "switch" stmts (PR ↵David Malcolm1-10/+32
tree-optimization/83510) PR tree-optimization/83510 reports that r255649 (for PR tree-optimization/83312) introduced a false positive for -Warray-bounds for array accesses within certain switch statements: those for which value-ranges allow more than one case to be reachable, but for which one or more of the VR-unreachable cases contain out-of-range array accesses. In the reproducer, after the switch in f is inlined into g, we have 3 cases for the switch (case 9, case 10-19, and default), within a loop that ranges from 0..9. With both the old and new code, vr_values::simplify_switch_using_ranges clears the EDGE_EXECUTABLE flag on the edge to the "case 10-19" block. This happens during the dom walk within the substitute_and_fold_engine. With the old code, the clearing of that EDGE_EXECUTABLE flag led to the /* Skip blocks that were found to be unreachable. */ code in the old implementation of vrp_prop::check_all_array_refs skipping the "case 10-19" block. With the new code, we have a second dom walk, and that dom_walker's ctor sets all edges to be EDGE_EXECUTABLE, losing that information. Then, dom_walker::before_dom_children (here, the subclass' check_array_bounds_dom_walker::before_dom_children) can return one edge, if there's a unique successor edge, and dom_walker::walk filters the dom walk to just that edge. Here we have two VR-valid edges (case 9 and default), and an VR-invalid successor edge (case 10-19). There's no *unique* valid successor edge, and hence taken_edge is NULL, and the filtering in dom_walker::walk doesn't fire. Hence we've lost the filtering of the "case 10-19" BB, hence the false positive. The issue is that we have two dom walks: first within vr_values' substitute_and_fold_dom_walker (which has skip_unreachable_blocks == false), then another within vrp_prop::check_all_array_refs (with skip_unreachable_blocks == true). Each has different "knowledge" about ruling out edges due to value-ranges, but we aren't combining that information. The former "knows" about out-edges at a particular control construct (e.g. at a switch), the latter "knows" about dominance, but only about unique successors (hence the problem when two out of three switch cases are valid). This patch combines the information by preserving the EDGE_EXECUTABLE flags from the first dom walk, and using it in the second dom walk, potentially rejecting additional edges. Doing so fixes the false positive. I attempted an alternative fix, merging the two dom walks into one, but that led to crashes in identify_jump_threads, so I went with this, as a less invasive fix. gcc/ChangeLog: PR tree-optimization/83510 * domwalk.c (set_all_edges_as_executable): New function.

2012-11-17This patch rewrites the old VEC macro-based interface into a new one based ↵Diego Novillo1-4/+2
on the template class 'vec'. This patch rewrites the old VEC macro-based interface into a new one based on the template class 'vec'. The user-visible changes are described in http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec. I have tested the patch pretty extensively: - Regular bootstraps on x86_64, ppc, ia64, sparc and hppa. - Bootstraps with --enable-checking=release - Bootstraps with --enable-checking=gc,gcac - Basic builds on all targets (using contrib/config-list.mk). We no longer access the vectors via VEC_* macros. The pattern is "VEC_operation (T, A, V, args)" becomes "V.operation (args)". The only thing I could not do is create proper ctors and dtors for the vec class. Since these vectors are stored in unions, we have to keep them as PODs (C++03 does not allow non-PODs in unions). This means that creation and destruction must be explicit. There is a new method vec<type, allocation, layout>::create() and another vec<type, allocation, layout>::destroy() to allocate the internal vector. For vectors that must be pointers, there is a family of free functions that implement the operations that need to tolerate NULL vectors. These functions all start with the prefix 'vec_safe_'. See the wiki page for details. The gengtype change removes the special handling for VEC() that used to exist in gengtype. Additionally, it allows gengtype to recognize templates of more than one argument and introduces the concept of an undefined type (useful for template arguments that may or may not be types). When a TYPE_UNDEFINED is reached, gengtype will ignore it if it happens inside a type marked with GTY((user)). Otherwise, it will emit an error. Finally, gengtype rejects root types marked GTY((user)) that are not first class pointers. 2012-11-16 Diego Novillo <dnovillo@google.com> VEC API overhaul (http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec) * vec.c (register_overhead): Convert it into member function of vec_prefix.
