2021-12-14Determine global memory accesses in ipa-modrefJan Hubicka1-14/+146
As discussed in PR103585, fatigue2 is now only benchmark from my usual testing set (SPEC2k6, SPEC2k17, CPP benchmarks, polyhedron, Firefox, clang) which sees important regression when inlining functions called once is limited. This prevents us from solving runtime issues in roms benchmarks and elsewhere. The problem is that there is perdida function that takes many arguments and some of them are array descriptors. We constant propagate most of their fields but still keep their initialization. Because perdida is quite fast, the call overhead dominates, since we need over 100 memory stores consuing about 35% of the overall benchmark runtime. The memory stores would be eliminated if perdida did not call fortran I/O which makes modref to thin that the array descriptors could be accessed. We are quite close discovering that they can't becuase they are non-escaping from function. This patch makes modref to distingush between global memory access (only things that escapes) and unkonwn accesss (that may access also nonescaping things reaching the function). This makes disambiguation for functions containing error handling better. Unfortunately the patch hits two semi-latent issues in Fortran frontned. First is wrong code in gfortran.dg/unlimited_polymorphic_3.f03. This can be turned into wrong code testcase on both mainline and gcc11 if the runtime call is removed, so I filled PR 103662 for it. There is TBAA mismatch for structure produced in FE. Second is issue with GOMP where Fortran marks certain parameters as non-escaping and then makes them escape via GOMP_parallel. For this I disabled the use of escape info in verify_arg which also disables the useful transform on perdida but still does useful work for e.g. GCC error handling. I will work on this incrementally. Bootstrapped/regtested x86_64-linux, lto-bootstrapped and also tested with clang build. I plan to commit this tomorrow if there are no complains (the patch is not completely short but conceptualy simple and handles a lot of common cases). gcc/ChangeLog: 2021-12-12 Jan Hubicka <hubicka@ucw.cz> PR ipa/103585 * ipa-modref-tree.c (modref_access_node::range_info_useful_p): Handle MODREF_GLOBAL_MEMORY_PARM.

2021-12-12Terminate BB analysis on NULL memory access in ipa-pure-const and ipa-modrefJan Hubicka1-0/+13
As discussed in the PR, we miss some optimization becuase gimple-ssa-isolate-paths turns NULL memory accesses to volatile and adds __builtin_trap after them. This is seen as a side-effect by IPA analysis and additionally the (fully unreachable) builtin_trap is believed to load all global memory. I think we should think of less intrusive gimple representation of this, but it is also easy enough to special case that in IPA analysers as done in this patch. This is a win even if we improve the representation since gimple-ssa-isolate-paths is run late and this way we improve optimization early. This affects 1623 functions during cc1plus link.

2021-12-11Fix handling of thunks in ipa-modrefJan Hubicka1-5/+5
Thunks are not transparent for ipa-modref summary since it cares about offsets from pointer parameters and also for virtual thunk about the read from memory in there. We however use function_or_virtual_thunk_symbol to get the summary that may lead to wrong code (and does in two testsuite testcases with patch I am working on). This is a first aid fix that is bacportable to gcc 11. We could easily produce summary for thunk on demand. I will look into it incrementally. It is not very important since we usually inline the thunk when we devirutalize... Bootstrapped/regtested x86_64-linux, will commit it shortly. gcc/ChangeLog: 2021-12-11 Jan Hubicka <hubicka@ucw.cz> * ipa-modref.c (get_modref_function_summary): Use ultimate_alias_target.

2021-11-21Improve base tracking in ipa-modrefJan Hubicka1-36/+35
on exchange2 benchamrk we miss some useful propagation because modref gives up very early on analyzing accesses through pointers. For example in int test (int *a) { int i; for (i=0; a[i];i++); return i+a[i]; } We are not able to determine that a[i] accesses are relative to a. This is because get_access requires the SSA name that is in MEM_REF to be PARM_DECL while on other places we use ipa-prop helper to work out the proper base pointers. This patch commonizes the code in get_access and parm_map_for_arg so both use the check properly and extends it to also figure out that newly allocated memory is not a side effect to caller. gcc/ChangeLog: 2021-11-21 Jan Hubicka <hubicka@ucw.cz> PR ipa/103227 * ipa-modref.c (parm_map_for_arg): Rename to ...

2021-11-17Fix modref summary streamingJan Hubicka1-4/+4
Fixes bug in streaming in modref access tree that now cause a failure of gamess benchmark. The bug is quite old (present in GCC11 release) but it needs quite interesting series of events to manifest. In particular 1) At lto time ISRA turns some parameters passed by reference to scalar 2) At lto time modref computes summaries for old parameters and then updates them but does so quite stupidly believing that the load from parameters are now unkonwn loads (rather than optimized out). This renders summary not very useful since it thinks every memory aliasing int is now accssed (as opposed as parameter dereference) 3) At stream in we notice too early that summary is useless, set every_access flag and drop the list. However while reading rest of the summary we overwrite the flag back to 0 which makes us to lose part of summary. 4) right selection of partitions needs to be done to avoid late modref from recalculating and thus fixing the summary. This patch fixes the stream in bug, however we also should fix updating of summaries. gcc/ChangeLog: 2021-11-17 Jan Hubicka <hubicka@ucw.cz> PR ipa/103246 * ipa-modref.c (read_modref_records): Fix streaminig in of every_access flag.

2021-11-15Track nondeterminism and interposable calls in ipa-modrefJan Hubicka1-33/+165
Adds tracking of two new flags in ipa-modref: nondeterministic and calls_interposable. First is set when function does something that is not guaranteed to be the same if run again (volatile memory access, volatile asm or external function call). Second is set if function calls something that does not bind to current def. nondeterministic enables ipa-modref to discover looping pure/const functions and it now discovers 138 of them during cc1plus link (which about doubles number of such functions detected late). We however can do more 1) We can extend FRE to eliminate redundant calls. I filled a PR103168 for that. A common case are inline functions that are not autodetected as ECF_CONST just becuase they do not bind to local def and can be easily handled. More tricky is to use modref summary to check what memory locations are read. 2) DSE can eliminate redundant stores The calls_interposable flag currently also improves tree-ssa-structalias on functions that are not binds_to_current_def since reads_global_memory is now not cleared by interposable functions. gcc/ChangeLog: * ipa-modref.h (struct modref_summary): Add nondeterministic and calls_interposable flags. * ipa-modref.c (modref_summary::modref_summary): Initialize new flags.

I wrote script comparing modref pure/const discovery with ipa-pure-const and found mistakes on both ends. This plugs the modref differences in handling looping pure consts which were previously missed due to early exits on ECF_CONST | ECF_PURE.

Make modref to also collect info whether function has side effects. This allows pure/const function detection and also handling functions which do store some memory in similar way as we handle pure/consts now. The code is symmetric to what ipa-pure-const does. Modref is actually more capable on proving that a given function is pure/const (since it understands that non-pure function can be called when it only modifies data on stack) so we could retire ipa-pure-const's pure-const discovery at some point.

2021-11-10Make EAF flags more regular (and expressive)Jan Hubicka1-97/+107
I hoped that I am done with EAF flags related changes, but while looking into the Fortran testcases I noticed that I have designed them in unnecesarily restricted way. I followed the scheme of NOESCAPE and NODIRECTESCAPE which is however the only property tht is naturally transitive. This patch replaces the existing flags by 9 flags: EAF_UNUSED EAF_NO_DIRECT_CLOBBER and EAF_NO_INDIRECT_CLOBBER EAF_NO_DIRECT_READ and EAF_NO_INDIRECT_READ EAF_NO_DIRECT_ESCAPE and EAF_NO_INDIRECT_ESCAPE EAF_NO_DIRECT_READ and EAF_NO_INDIRECT_READ So I have removed the unified EAF_DIRECT flag and made each of the flags to come in direct and indirect variant. Newly the indirect variant is not implied by direct (well except for escape but it is not special cased in the code) Consequently we can analyse i.e. the case where function reads directly and clobber indirectly as in the following testcase: struct wrap { void **array; }; __attribute__ ((noinline)) void write_array (struct wrap *ptr) { ptr->array[0]=0; } int test () { void *arrayval; struct wrap w = {&arrayval}; write_array (&w); return w.array == &arrayval; } This is pretty common in array descriptors and also C++ pointer wrappers or structures containing pointers to arrays. Other advantage is that !binds_to_current_def_p functions we can still track the fact that the value is not clobbered indirectly while previously we implied EAF_DIRECT for all three cases. Finally the propagation becomes more regular and I hope easier to understand because the flags are handled in a symmetric way. In tree-ssa-structalias I now produce "callarg" var_info as before and if necessary also "indircallarg" for the indirect accesses. I added some logic to optimize the common case where we can not make difference between direct and indirect. gcc/ChangeLog: 2021-11-09 Jan Hubicka <hubicka@ucw.cz> * tree-core.h (EAF_DIRECT): Remove.

Adds tracking of accesses relative to static chain into modref load/stores analysis. This helps some Fortran benchmarks however it is still quite limited.

2021-11-07Fix inter-procedural EAF flags propagation with respect to ↵Jan Hubicka1-25/+170
!binds_to_current_def_p While proofreading the code for handling EAF flags of !binds_to_current_def_p I noticed that the interprocedural dataflow actually ignores the flag possibly introducing wrong code on quite complex interposable functions in non-trivial recursion cycles (or at ltrans partition boundary). This patch unifies the flags changes to single place (remove_useless_eaf_flags) and does extend modref_merge_call_site_flags to do the right thing. lto-bootstrapped/regtested x86_64-linux.

2021-11-07Implement intra-procedural dataflow in ipa-modref flags propagation.Jan Hubicka1-20/+224
implement the (long promised) intraprocedural dataflow for propagating eaf flags, so we can handle parameters that participate in loops in SSA graphs. Typical example are acessors that walk linked lists, for example. I implemented dataflow using the standard iteration over BBs in RPO some time ago, but did not like it becuase it had measurable compile time impact with very small code quality effect. This is why I kept mainline to do the DFS walk instead. The reason is that we care about flags of SSA names that corresponds to parameters and those can be often determined from a small fraction of the SSA graph so solving dataflow for all SSA names in a function is a waste. This patch implements dataflow more carefully. The DFS walk is kept in place to solve acyclic cases and discover the relevat part of SSA graph into new graph (which is similar to one used for inter-procedrual dataflow - we only need to know the edges and if the access is direct or derefernced). The RPO iterative dataflow then works on this simplified graph. This seems to be fast in practice. For GCC linktime we do dataflow for 4881 functions. Out of that 4726 finishes in one iteration, 144 in two and 10 in 3. Overall 31979 functions are analysed, so we do dataflow only for bit over of 10% of cases. 131123 edges are visited by the solver. I measured no compile time impact of this. gcc/ChangeLog: * ipa-modref.c (modref_lattice): Add do_dataflow, changed and propagate_to fields.

2021-11-03Fix wrong code caulsed by retslot EAF flags propagation [PR103040]Jan Hubicka1-31/+104
Fixe (quite nasty) thinko in how I propagate EAF flags from callee to caller. In this case some flags needs to be changed. In particular - EAF_NOT_RETURNED in callee does not really mean EAF_NOT_RETURNED in caller since we speak of different return values - if callee escapes the parametr, we caller may return it - for retslot the rewritting is even bit more funny, since escaping to of return slot to return slot is not really an escape, however escape of argument to itself is. This patch should correct all of the cases above and does fix the testcase from PR103040. Bootstrapped/regtested x86_64 with all languages.

2021-10-31Improve handling of return slot in ipa-pure-const and modref.Jan Hubicka1-1/+1
while preparing testcase for return slot tracking I noticed that both ipa-pure-const and modref treat return slot writes as non-local which prevents detecting functions as pure or not modifying global state. Fixed by making points_to_local_or_readonly_memory_p to special case return slot. This is bit of a side case, but presently at all uses of points_to_local_or_readonly_memory_p we want to handle return slot this way. I also noticed that we handle gimple copy unnecesarily pesimistically. This does not make difference right now since we do no not track non-scalars, but I fixed it anyway. Bootstrapped/regtested x86_64-linux, comitted. gcc/ChangeLog: * ipa-fnsummary.c: Include tree-dfa.h.

Extend modref and tree-ssa-structalias to handle retslot flags. Since retslot it essentially a hidden argument that is known to be write-only we can do pretty much the same stuff as we do for regular parameters. I plan to add static chain handling similar way. We do not handle IPA propagation of retslot flags (where return slot is initialized via return slot of other function). For this ipa-prop needs to be extended to understand retslot as well.
