2017-08-04Pool alignment information for common basesRichard Sandiford1-1/+8
This patch is a follow-on to the fix for PR81136. The testcase for that PR shows that we can (correctly) calculate different base alignments for two data_references but still tell that their misalignments wrt the vector size are equal. This is because we calculate the base alignments for each dr individually, without looking at the other drs, and in general the alignment we calculate is only guaranteed if the dr's DR_REF actually occurs. This is working as designed, but it does expose a missed opportunity. We know that if a vectorised loop is reached, all statements in that loop execute at least once, so it should be safe to pool the alignment information for all the statements we're vectorising. The only catch is that DR_REFs for masked loads and stores only occur if the mask value is nonzero. For example, in: struct s __attribute__((aligned(32))) { int misaligner; int array[N]; }; int *ptr; for (int i = 0; i < n; ++i) ptr[i] = c[i] ? ((struct s *) (ptr - 1))->array[i] : 0; we can only guarantee that ptr points to a "struct s" if at least one c[i] is true. This patch adds a DR_IS_CONDITIONAL_IN_STMT flag to record whether the DR_REF is guaranteed to occur every time that the statement executes to completion. It then pools the alignment information for references that aren't conditional in this sense. 2017-08-04 Richard Sandiford <richard.sandiford@linaro.org> gcc/ PR tree-optimization/81136 * tree-vectorizer.h: Include tree-hash-traits.h.

2017-08-04Handle data dependence relations with different basesRichard Sandiford1-16/+32
This patch tries to calculate conservatively-correct distance vectors for two references whose base addresses are not the same. It sets a new flag DDR_COULD_BE_INDEPENDENT_P if the dependence isn't guaranteed to occur. The motivating example is: struct s { int x[8]; }; void f (struct s *a, struct s *b) { for (int i = 0; i < 8; ++i) a->x[i] += b->x[i]; } in which the "a" and "b" accesses are either independent or have a dependence distance of 0 (assuming -fstrict-aliasing). Neither case prevents vectorisation, so we can vectorise without an alias check. I'd originally wanted to do the same thing for arrays as well, e.g.: void f (int a[][8], struct b[][8]) { for (int i = 0; i < 8; ++i) a[0][i] += b[0][i]; } I think this is valid because C11 6.7.6.2/6 says: For two array types to be compatible, both shall have compatible element types, and if both size specifiers are present, and are integer constant expressions, then both size specifiers shall have the same constant value. So if we access an array through an int (*)[8], it must have type X[8] or X[], where X is compatible with int. It doesn't seem possible in either case for "a[0]" and "b[0]" to overlap when "a != b". However, as the comment above "if (same_base_p)" explains, GCC is more forgiving: it supports arbitrary overlap of arrays and allows arrays to be accessed with different dimensionality. There are examples of this in PR50067. The patch therefore only handles references that end in a structure field access. There are two ways of handling these dependences in the vectoriser: use them to limit VF, or check at runtime as before. I've gone for the approach of checking at runtime if we can, to avoid limiting VF unnecessarily, but falling back to a VF cap when runtime checks aren't allowed. The patch tests whether we queued an alias check with a dependence distance of X and then picked a VF <= X, in which case it's safe to drop the alias check. Since vect_prune_runtime_alias_check_list can be called twice with different VF for the same loop, it's no longer safe to clear may_alias_ddrs on exit. Instead we should use comp_alias_ddrs to check whether versioning is necessary. 2017-08-04 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-data-ref.h (subscript): Add access_fn field.

2017-07-03Add a helper for getting the overall alignment of a DRRichard Sandiford1-0/+10
This combines the information from previous patches to give a guaranteed alignment for the DR as a whole.

2017-07-03Add DR_BASE_ALIGNMENT and DR_BASE_MISALIGNMENTRichard Sandiford1-0/+38
This patch records the base alignment and misalignment in innermost_loop_behavior, to avoid the second-guessing that was previously done in vect_compute_data_ref_alignment. It also makes vect_analyze_data_refs use dr_analyze_innermost, instead of having an almost-copy of the same code. I wasn't sure whether the alignments should be measured in bits (for consistency with most other interfaces) or in bytes (for consistency with DR_ALIGNED_TO, now DR_OFFSET_ALIGNMENT, and with *_ptr_info_alignment). I went for bytes because: - I think in practice most consumers are going to want bytes. E.g. using bytes avoids having to mix TYPE_ALIGN and TYPE_ALIGN_UNIT in vect_compute_data_ref_alignment. - It means that any bit-level paranoia is dealt with when building the innermost_loop_behavior and doesn't get pushed down to consumers. 2017-07-03 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-data-ref.h (innermost_loop_behavior): Add base_alignment and base_misalignment fields.

2017-07-03Add DR_STEP_ALIGNMENTRichard Sandiford1-0/+4
A later patch adds base alignment information to innermost_loop_behavior. After that, the only remaining piece of alignment information that wasn't immediately obvious was the step alignment. Adding that allows a minor simplification to vect_compute_data_ref_alignment, and also potentially improves the handling of variable strides for outer loop vectorisation. A later patch will also use it to give the alignment of the DR as a whole. 2017-07-03 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-data-ref.h (innermost_loop_behavior): Add a step_alignment field.

This patch renames DR_ALIGNED_TO to DR_OFFSET_ALIGNMENT, to avoid confusion with the upcoming DR_BASE_ALIGNMENT. Nothing needed the value as a tree, and the value is clipped to BIGGEST_ALIGNMENT (maybe it should be MAX_OFILE_ALIGNMENT?) so we might as well use an unsigned int instead. 2017-07-03 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-data-ref.h (innermost_loop_behavior): Replace aligned_to with offset_alignment.

2015-09-08Remove limit_scopsAditya Kumar1-0/+1
This patch removes graphite-scop-detection.c:limit_scops function and fix related issues arising because of that. The functionality limit_scop was added as an intermediate step to discard the loops which graphite could not handle. Removing limit_scop required handling of different cases of loops and surrounding code. The scop is now larger so most test cases required 'number of scops detected' to be fixed. By increasing the size of scop we can now optimize loops which are 'siblings' of each other. This could enable loop fusion on a number of loops. Since in the graphite framework we mostly want to opimize loop-nests/adjacent-loops, we now discard scops with less than 2 loops. We also discard scops without any data references. Essentially: - Remove limite_scops. - Only select scops when there are at least two loops (loop nest or, side by side). - Discard loops without data-refs. - Fix test cases.

2013-03-29Add uniform debug dump function names.Lawrence Crowl1-0/+6
Add some overloaded functions that provide uniform debug dump function names. These names are: debug: the general debug dumper debug_verbose: for more details debug_raw: for the gory details debug_head: for the heads of declarations, e.g. function heads debug_body: for the bodies of declarations, e.g. function bodies Not all types have the last four versions. The debug functions come in two flavors, those that take pointers to the type, and those that take references to the type. The first handles printing of '<nil>' for null pointers. The second assumes a valid reference, and prints the content. Example uses are as follows: cp_token t, *p; debug (t); debug (p); From the debugger, use call debug (t) The functions sets implemented are: debug (only) basic_block_def, const bitmap_head_def, cp_binding_level, cp_parser, cp_token, data_reference, die_struct, edge_def, gimple_statement_d, ira_allocno, ira_allocno_copy, live_range, lra_live_range, omega_pb_d, pt_solution, const rtx_def, sreal, tree_live_info_d, _var_map, vec<cp_token, va_gc>, vec<data_reference_p>, vec<ddr_p>, vec<rtx>, vec<tree, va_gc>, debug and debug_raw simple_bitmap_def debug and debug_verbose expr_def, struct loop, vinsn_def debug, debug_raw, debug_verbose, debug_head, debug_body const tree_node This patch is somewhat different from the original plan at gcc.gnu.org/wiki/cxx-conversion/debugging-dumps. The reason is that gdb has an incomplete implementation of C++ call syntax; requiring explicit specification of template arguments and explicit specification of function arguments even when they have default values. So, the original plan would have required typing call dump <cp_token> (t, 0, 0, stderr) which is undesireable. Instead instead of templates, we overload plain functions. This adds a small burden of manually adding the pointer version of dump for each type. Instead of default function arguments, we simply assume the default values. Most of the underlying dump functions did not use the options and indent parameters anyway. Several provide FILE* parameters, but we expect debugging to use stderr anyway. So, the explicit specification of arguments was not as valuable as we thought initially. Finally, a change of name from dump to debug reflect the implicit output to stderr.

2012-11-17This patch rewrites the old VEC macro-based interface into a new one based ↵Diego Novillo1-63/+50
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.

2012-03-02 Richard Guenther <rguenther@suse.de> PR tree-optimization/52406 * tree-data-ref.h: Update documentation about DR_BASE_OBJECT. (struct indices): Add unconstrained_base member. (struct dr_alias): Remove unused vops member. (DR_UNCONSTRAINED_BASE): New define. * tree-data-ref.c (dr_analyze_indices): For COMPONENT_REFs add indices to allow their disambiguation. Make DR_BASE_OBJECT be an artificial access that covers the whole indexed object, or mark it with DR_UNCONSTRAINED_BASE if we cannot do so. Canonicalize plain decl base-objects to their MEM_REF variant. (dr_may_alias_p): When the base-object of either data reference has unknown size use only points-to information. (compute_affine_dependence): Make dumps easier to read and more verbose. * tree-vect-data-ref.c (vector_alignment_reachable_p): Use DR_REF when looking for packed references. (vect_supportable_dr_alignment): Likewise. * gcc.dg/torture/pr52406.c: New testcase. From-SVN: r184789
