Now that things have stabilized, we can remove the old code.

2021-09-28Control all jump threading passes with -fjump-threads.Aldy Hernandez1-0/+3
Last year I mentioned that -fthread-jumps was being ignored by the majority of our jump threading passes, and Jeff said he'd be in favor of fixing this. This patch remedies the situation, but it does change existing behavior. Currently -fthread-jumps is only enabled for -O2, -O3, and -Os. This means that even if we restricted all jump threading passes with -fthread-jumps, DOM jump threading would still seep through since it runs at -O1. I propose this patch, but it does mean that DOM jump threading would have to be explicitly enabled with -O1 -fthread-jumps. gcc/ChangeLog: * tree-ssa-threadbackward.c (pass_thread_jumps::gate): Check flag_thread_jumps.

With all the pieces that have gone in, the implementation of the hybrid threader is straightforward: convert the current state into SSA imports that the solver will understand, and let the path solver precompute ranges and relations for the path. After this setup is done, we can use the range_query API to solve gimple statements in the threader. The forward threader is now engine agnostic so there are no changes to the threader per se. I have put the hybrid bits in tree-ssa-threadedge.*, instead of VRP, because they will also be used in the evrp removal of the DOM/threader, which is my next task. Most of the patch, is actually test changes. I have gone through every single one and verified that we're correct. Most were trivial dump file name changes, but others required going through the IL an certifying that the different IL was expected. For example, in pr59597.c, we have one less thread because the ASSERT_EXPR was getting in the way, and making it seem like things were not crossing loops. The hybrid threader sees the correct representation of the IL, and avoids threading this one case. The final numbers are a 12.16% improvement in jump threads immediately after VRP, and a 0.82% improvement in overall jump threads. The performance drop is 0.6% (plus the 1.43% hit from moving the embedded threader into its own pass). As I've said, I'd prefer to keep the threader in its own pass, but if this is an issue, we can address this with a shared ranger when VRP is replaced with an evrp instance (upcoming). Note, that these numbers are slightly different than what I originally posted. A few correctness tweaks, plus restricting loop threads, made the difference. That being said, I was aiming for par. A 12% gain is just gravy ;-). When we merge the threaders, we should see even better numbers-- and we'll have the benefit of an entire release stress testing the solver. As I mentioned in my introductory note, paths ending in MEM_REF conditional are missing. In reality, this didn't make a difference, as it was so rare. However, as a follow-up, I will distill a test and add a suitable PR to keep us honest. There is a one-line change to libgomp/team.c silencing a new used uninitialized warning. As my previous work with the threaders has shown, warnings flare up after each improvement to jump threading. I expect this to be no different. I've promised Jakub to investigate fully, so I will analyze and add the appropriate PR for the warning experts. Oh yeah, the new pass dump is called vrp-threader[12] to match each VRP[12] pass. However, there's no reason for it to either be named vrp-threader, or for it to live in tree-vrp.c. Tested on x86-64 Linux. OK? p.s. "Did I say 5 weeks?

2021-09-23Overhaul jump thread state in forward threader.Aldy Hernandez1-183/+139
I've been pulling state from across the forward jump threader into the jt_state class, but it it still didn't feel right. The ultimate goal was to keep track of candidate threading paths so that the simplifier could simplify statements with the path as context. This patch completes the transition, while cleaning up a lot of things in the process. I've revamped both state and the simplifier such that a base state class contains only the blocks as they're registered, and any pass specific knowledge is where it belongs... in the pass. This allows VRP to keep its const and copies business, and DOM to keep this as well as its evrp client. This makes the threader cleaner, as it will now have no knowledge of either const/copies or evrp. This also paves the wave for the upcoming hybrid threader, which will just derive the state class and provide almost nothing, since the ranger doesn't need to register any equivalences or ranges as it folds. There is some code duplication in the simplifier, since both the DOM and VRP clients use a vr_values based simplifier, but this is temporary as the VRP client is about to be replaced with a hybrid ranger. For a better view of what this patch achieves, here are the base classes: class jt_state { public: virtual ~jt_state () { } virtual void push (edge); virtual void pop (); virtual void register_equiv (tree dest, tree src, bool update_range = false); virtual void register_equivs_edge (edge e); virtual void register_equivs_stmt (gimple *, basic_block, class jt_simplifier *); virtual void record_ranges_from_stmt (gimple *stmt, bool temporary); void get_path (vec<basic_block> &); void append_path (basic_block); void dump (FILE *); void debug (); private: auto_vec<basic_block> m_blocks; }; class jt_simplifier { public: virtual ~jt_simplifier () { } virtual tree simplify (gimple *, gimple *, basic_block, jt_state *) = 0; }; There are no functional changes. gcc/ChangeLog: * tree-ssa-dom.c (class dom_jump_threader_simplifier): Rename...

2021-09-19Minor cleanups to forward threader.Aldy Hernandez1-50/+19
Every time we allocate a threading edge we push it onto the path in a distinct step. There's no need to do this in two steps, and avoiding this, keeps us from exposing the internals of the registry. I've also did some tiny cleanups in thread_across_edge, most importantly removing the bitmap in favor of an auto_bitmap.

2021-09-13Remove references to FSM threads.Aldy Hernandez1-5/+5
Now that the jump thread back registry has been split into the generic copier and the custom (old) copier, it becomes trivial to remove the FSM bits from the jump threaders. First, there's no need for an EDGE_FSM_THREAD type. The only reason we were looking at the threading type was to determine what type of copier to use, and now that the copier has been split, there's no need to even look. However, there is one check in register_jump_thread where we verify that only the generic copier can thread through back-edges. I've removed that check in favor of a flag passed to the constructor. I've also removed all the FSM references from the code and tests. Interestingly, some tests weren't even testing the right thing. They were testing for "FSM" which would catch jump thread paths as well as the backward threader *failing* on registering a path. *big eye roll* The only remaining code that was actually checking for EDGE_FSM_THREAD was adjust_paths_after_duplication, and the checks could be written without looking at the edge type at all. For the record, the code there is horrible: it's convoluted, hard to read, and doesn't have any tests. I'd smack myself if I could go back in time. All that remains are the FSM references in the --param's themselves. I think we should s/fsm/threader/, since I envision a day when we can share the cost basis code between the threaders. However, I don't know what the proper procedure is for renaming existing compiler options. By the way, param_fsm_maximum_phi_arguments is no longer relevant after the rewrite. We can nuke that one right away. Tested on x86-64 Linux. gcc/ChangeLog: * tree-ssa-threadbackward.c (back_threader_profitability::profitable_path_p): Remove FSM references.

2021-09-11Refactor jump_thread_path_registry.Aldy Hernandez1-1/+1
In an attempt to refactor thread_through_all_blocks(), I've realized that there is a mess of code dealing with coexisting forward and backward thread types. However, this is an impossible scenario, as the registry contains either forward/old-style threads, or backward threads (EDGE_FSM_THREADs), never both. The fact that both types of threads cannot coexist, simplifies the code considerably. For that matter, it splits things up nicely because there are some common bits that can go into a base class, and some differing code that can go into derived classes. Diving things in this way makes it very obvious which parts belong in the old-style copier and which parts belong to the generic copier. Doing all this provided some nice cleanups, as well as fixing a latent bug in adjust_paths_after_duplication. The diff is somewhat hard to read, so perhaps looking at the final output would be easier. A general overview of what this patch achieves can be seen by just looking at this simplified class layout: // Abstract class for the jump thread registry. class jt_path_registry { public: jt_path_registry (); virtual ~jt_path_registry (); bool register_jump_thread (vec<jump_thread_edge *> *); bool thread_through_all_blocks (bool peel_loop_headers); jump_thread_edge *allocate_thread_edge (edge e, jump_thread_edge_type t); vec<jump_thread_edge *> *allocate_thread_path (); protected: vec<vec<jump_thread_edge *> *> m_paths; unsigned long m_num_threaded_edges; private: virtual bool update_cfg (bool peel_loop_headers) = 0; }; // Forward threader path registry using a custom BB copier. class fwd_jt_path_registry : public jt_path_registry { public: fwd_jt_path_registry (); ~fwd_jt_path_registry (); void remove_jump_threads_including (edge); private: bool update_cfg (bool peel_loop_headers) override; void mark_threaded_blocks (bitmap threaded_blocks); bool thread_block_1 (basic_block, bool noloop_only, bool joiners); bool thread_block (basic_block, bool noloop_only); bool thread_through_loop_header (class loop *loop, bool may_peel_loop_headers); class redirection_data *lookup_redirection_data (edge e, enum insert_option); hash_table<struct removed_edges> *m_removed_edges; hash_table<redirection_data> *m_redirection_data; }; // Backward threader path registry using a generic BB copier. class back_jt_path_registry : public jt_path_registry { private: bool update_cfg (bool peel_loop_headers) override; void adjust_paths_after_duplication (unsigned curr_path_num); bool duplicate_thread_path (edge entry, edge exit, basic_block *region, unsigned n_region, unsigned current_path_no); bool rewire_first_differing_edge (unsigned path_num, unsigned edge_num); }; That is, the forward and backward bits have been completely split, while deriving from a base class for the common functionality. Most everything is mechanical, but there are a few gotchas: a) back_jt_path_registry::update_cfg(), which contains the backward threading specific bits, is rather simple, since most of the code in the original thread_through_all_blocks() only applied to the forward threader: removed edges, mark_threaded_blocks, thread_through_loop_header, the copy tables (*). (*) The back threader has its own copy tables in duplicate_thread_path. b) In some cases, adjust_paths_after_duplication() was commoning out so many blocks that it was removing the initial EDGE_FSM_THREAD marker. I've fixed this. c) AFAICT, when run from the forward threader, thread_through_all_blocks() attempts to remove threads starting with an edge already seen, but it would never see anything because the loop doing the checking only has a visited_starting_edges.contains(), and no corresponding visited_starting_edges.add(). The add() method in thread_through_all_blocks belongs to the backward threading bits, and as I've explained, both types cannot coexist. I've removed the checks in the forward bits since they don't appear to do anything. If this was an oversight, and we want to avoid threading already seen edges in the forward threader, I can move this functionality to the base class. Ultimately I would like to move all the registry code to tree-ssa-threadregistry.*. I've avoided this in this patch to aid in review. My apologies for this longass explanation, but I want to make sure we're covering all of our bases. Tested on x86-64 Linux by a very tedious process of moving chunks around, running "make check-gcc RUNTESTFLAGS=tree-ssa.exp", and repeating ad-nauseum. And of course, by running a full bootstrap and tests. OK? p.s.

2021-07-27Abstract out (forward) jump threader state handling.Aldy Hernandez1-95/+124
The *forward* jump threader has multiple places where it pushes and pops state, and where it sets context up for the jump threading simplifier callback. Not only are the idioms repetitive, but the only reason for passing const_and_copies, avail_exprs_stack, and the evrp engine around are so we can set up context. As part of my jump threading work, I will divorce the evrp engine from the DOM jump threader, replacing it with a subset of the path solver I have just contributed. Since this will entail passing even more context around, I've abstracted out the state handling so it can be passed around in one object. This cleans up the code, and also makes it trivial to set up context with another engine in the future. FWIW, I've used these cleanups and the path solver in a POC to improve DOM's threaded edges by an additional 5%, and the overall threading opportunities in the compiler by 1%. This is in addition to the gains I have documented in the backwards threader rewrite. There are no functional changes with this patch. Tested on x86-64 Linux. gcc/ChangeLog: * tree-ssa-dom.c (dom_jump_threader_simplifier): Put avail_exprs_stack in the class, instead of passing it to jump_threader_simplifier.

2021-04-30Jump threader refactor.Aldy Hernandez1-235/+181
This is an overall refactor of the jump threader, both for the low level bits in tree-ssa-threadupdate.* and the high level bits in tree-ssa-threadedge.*. There should be no functional changes. Some of the benefits of the refactor are: a) Eliminates some icky global state (for example the x_vr_values hack). b) Provides some semblance of an API for the threader. c) Makes it clearer to see what parts are from the high level threader, and what parts belong in the low level path registry and BB threading mechanism. d) Avoids passing a ton of variables around. e) Provides for easier sharing with the backward threader. f) Merged simplify stmt code in VRP and DOM as they were nearly identical. This has been bootstrapped and regression tested on x86-64 Linux. Jeff had also been testing this path as part of his Fedora throughout the off-season. gcc/ChangeLog: * tree-ssa-dom.c (class dom_jump_threader_simplifier): New.

long and cumbersome. The base class for ranges is currently value_range_base, which is rather long and cumbersome. It also occurs more often than the derived class of value_range. To avoid confusion, and save typing, this patch does a global rename from value_range to value_range_equiv, and from value_range_base to value_range. This way, the base class is simply value_range, and the derived class is value_range_equiv which explicitly states what it does. From-SVN: r277847

2019-08-13Protect some checks of DECL_FUNCTION_CODERichard Sandiford1-0/+1
This patch protects various uses of DECL_FUNCTION_CODE that didn't obviously check for BUILT_IN_NORMAL first (either directly or in callers). They could therefore trigger for functions that either aren't built-ins or are a different kind of built-in. Also, the patch removes a redundant GIMPLE_CALL check from optimize_stdarg_builtin, since it gave the impression that the stmt was less well checked than it actually is. 2019-08-13 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR middle-end/91421 * attribs.c (decl_attributes): Check the DECL_BUILT_IN_CLASS before the DECL_FUNCTION_CODE. * calls.c (maybe_warn_alloc_args_overflow): Use fndecl_built_in_p to check for a BUILT_IN_ALLOCA call. * ipa-cp.c (ipa_get_indirect_edge_target_1): Likewise for BUILT_IN_UNREACHABLE.

2017-12-12[SFN] introduce statement frontier notes, still disabledAlexandre Oliva1-8/+17
This patch completes the infrastructure for the introduction of statement frontiers in C-family languages. It brings in all the code remaining code needed to introduce and transform begin stmt trees, gimple stmts, insns and notes, and ultimately use them to generate the is_stmt column in DWARF2+ line number tables/programs, however none of it is activated: the option that would do so will be introduced in a subsequent patch.

2017-12-12[SFN] boilerplate changes in preparation to introduce nonbind markersAlexandre Oliva1-1/+1
This patch introduces a number of new macros and functions that will be used to distinguish between different kinds of debug stmts, insns and notes, namely, preexisting debug bind ones and to-be-introduced nonbind markers. In a seemingly mechanical way, it adjusts several uses of the macros and functions, so that they refer to narrower categories when appropriate. These changes, by themselves, should not have any visible effect in the compiler behavior, since the upcoming debug markers are never created with this patch alone. for gcc/ChangeLog * gimple.h (enum gimple_debug_subcode): Add GIMPLE_DEBUG_BEGIN_STMT.
