2021-06-28ipa-sra: Introduce a mini-DCE to tree-inline.c (PR 93385)Martin Jambor1-15/+114
I was asked by Richi to split my fix for PR 93385 for easier review into IPA-SRA materialization refactoring and the actual DCE addition. This is the second part that actually contains the DCE of statements that IPA-SRA should not leave behind because they can have problematic side effects, even if they are useless, so that we do not depend on tree-dce to remove them for correctness. The patch fixes the problem by doing a def-use walk when materializing clones, marking which statements should not be copied and which SSA_NAMEs do not need to be computed because eventually they would be DCEd. We do this on the original function body and tree-inline simply does not copy statements which are "dead." The only complication is removing dead argument calls because that needs to be communicated to callee redirection code using the infrastructure introduced by the previous patch. I added all testcases of the original patch to this one, although some probably test behavior introduced in the previous patch. gcc/ChangeLog: 2021-05-12 Martin Jambor <mjambor@suse.cz> PR ipa/93385 * ipa-param-manipulation.h (class ipa_param_body_adjustments): New members m_dead_stmts and m_dead_ssas. * ipa-param-manipulation.c (ipa_param_body_adjustments::mark_dead_statements): New function.

2021-06-28ipa-sra: Restructure how cloning and call redirection communicate (PR 93385)Martin Jambor1-349/+436
I was asked by Richi to split my fix for PR 93385 for easier review into IPA-SRA materialization refactoring and the actual DCE addition. Fortunately it was mostly natural except for a temporary weird condition in ipa_param_body_adjustments::modify_call_stmt. Additionally. In addition to the patch I posted previously, this one also deallocated the newly added summary in toplev::finalize and fixes a mistakenly uninitialized field. This is the first part which basically replaces performed_splits in clone_info and the code which generates it, keeps it up-to-date and consumes it with new edge summaries which are much nicer. It simply contains 1) a mapping from the original argument indices to the actual indices in the call statement as it is now, 2) information needed to identify arguments representing pass-through IPA-SRA splits with which have been added to the call arguments in place of an original argument/reference and 3) a delta to the index where va_args may start - so basically directly all the information that the consumer of performed_splits had to compute and we also do not need the weird dummy declarations. The main disadvantage is that the information has to be created (and kept up-to-date) for all call graph edges associated with the given statement from all clones (including inline clones) of the clone where splitting or removal happened first. But all of this happens during clone materialization so the only effect on WPA memory consumption is the removal of a pointer from clone_info. The statement modification code also has to know the statement from the original function in order to be able to locate the edge summaries which at this point are still keyed to these. However, the code is already quite heavily dependant on how things are structured in tree-inline.c and in order to fix bugs like these it probably has to be. The subsequent patch needs this new information to be able to remove arguments from calls during materialization and communicate this information to the call redirection. gcc/ChangeLog: 2021-05-17 Martin Jambor <mjambor@suse.cz> PR ipa/93385 * symtab-clones.h (clone_info): Removed member param_adjustments. * ipa-param-manipulation.h: Adjust initial comment to reflect how we deal with pass-through splits now.

2020-10-22Materialize clones on demandJan Hubicka1-0/+7
this patch removes the pass to materialize all clones and instead this is now done on demand. The motivation is to reduce lifetime of function bodies in ltrans that should noticeably reduce memory use for highly parallel compilations of large programs (like Martin does) or with partitioning reduced/disabled. For cc1 with one partition the memory use seems to go down from 4gb to cca 1.5gb (seeing from top, so this is not particularly accurate). gcc/ChangeLog: 2020-10-22 Jan Hubicka <hubicka@ucw.cz> * cgraph.c (cgraph_node::get_untransformed_body): Perform lazy clone materialization. * cgraph.h (cgraph_node::materialize_clone): Declare.

2020-07-02ipa-sra: Prevent constructing debug info from wrong argumentMartin Jambor1-1/+5
The mechanism generating debug info for removed parameters did not adjust index of the argument in the call statement to take into account extra arguments IPA-SRA might have produced when splitting a strucutre. This patch addresses that omission and stops gdb from showing incorrect value for the removed parameter and says "value optimized out" instead. The guality testcase will end up as UNSUPPORTED in the results which is how Richi told me on IRC we deal with this. It is possible to generate debug info to actually show the value of the removed parameter but so far my approaches to do just that seem toocontroversial (https://gcc.gnu.org/pipermail/gcc-patches/2020-May/546705.html), so before I come up with something better I'd like to push this to master and the gcc-10 branch in time for the GCC 10.2 release. gcc/ChangeLog: 2020-07-01 Martin Jambor <mjambor@suse.cz> PR debug/95343 * ipa-param-manipulation.c (ipa_param_adjustments::modify_call): Adjust argument index if necessary. gcc/testsuite/ChangeLog: 2020-07-01 Martin Jambor <mjambor@suse.cz> PR debug/95343 * gcc.dg/guality/pr95343.c: New test.

2020-05-07extend DECL_GIMPLE_REG_P to all typesRichard Biener1-5/+1
This extends DECL_GIMPLE_REG_P to all types so we can clear TREE_ADDRESSABLE even for integers with partial defs, not just complex and vector variables. To make that transition easier the patch inverts DECL_GIMPLE_REG_P to DECL_NOT_GIMPLE_REG_P since that makes the default the current state for all other types besides complex and vectors. For the testcase in PR94703 we're able to expand the partial def'ed local integer to a register then, producing a single movl rather than going through the stack. On i?86 this execute FAILs gcc.dg/torture/pr71522.c because we now expand a round-trip through a long double automatic var to a register fld/fst which normalizes the value. For that during RTL expansion we're looking for problematic punnings of decls and avoid pseudos for those - I chose integer or BLKmode accesses on decls with modes where precision doesn't match bitsize which covers the XFmode case. 2020-05-07 Richard Biener <rguenther@suse.de> PR middle-end/94703 * tree-core.h (tree_decl_common::gimple_reg_flag): Rename ...

2019-08-13Use checking forms of DECL_FUNCTION_CODE (PR 91421)Richard Sandiford1-4/+1
We were shoe-horning all built-in enumerations (including frontend and target-specific ones) into a field of type built_in_function. This was accessed as either an lvalue or an rvalue using DECL_FUNCTION_CODE. The obvious danger with this (as was noted by several ??? comments) is that the ranges have nothing to do with each other, and targets can easily have more built-in functions than generic code. But my patch to make the field bigger was the straw that finally made the problem visible. This patch therefore: - replaces the field with a plain unsigned int - turns DECL_FUNCTION_CODE into an rvalue-only accessor that checks that the function really is BUILT_IN_NORMAL - adds corresponding DECL_MD_FUNCTION_CODE and DECL_FE_FUNCTION_CODE accessors for BUILT_IN_MD and BUILT_IN_FRONTEND respectively - adds DECL_UNCHECKED_FUNCTION_CODE for places that need to access the underlying field (should be low-level code only) - adds new helpers for setting the built-in class and function code - makes DECL_BUILT_IN_CLASS an rvalue-only accessor too, since all assignments should go through the new helpers 2019-08-13 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR middle-end/91421 * tree-core.h (function_decl::function_code): Change type to unsigned int. * tree.h (DECL_FUNCTION_CODE): Rename old definition to...

2017-12-20poly_int: get_ref_base_and_extentRichard Sandiford1-2/+2
This patch changes the types of the bit offsets and sizes returned by get_ref_base_and_extent to poly_int64. There are some callers that can't sensibly operate on polynomial offsets or handle cases where the offset and size aren't known exactly. This includes the IPA devirtualisation code (since there's no defined way of having vtables at variable offsets) and some parts of the DWARF code. The patch therefore adds a helper function get_ref_base_and_extent_hwi that either returns exact HOST_WIDE_INT bit positions and sizes or returns a null base to indicate failure. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree-dfa.h (get_ref_base_and_extent): Return the base, size and max_size as poly_int64_pods rather than HOST_WIDE_INTs.

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.
