2021-01-19alias: Fix offset checks involving section anchors [PR92294]Richard Sandiford1-16/+31
memrefs_conflict_p assumes that: [XB + XO, XB + XO + XS) does not alias [YB + YO, YB + YO + YS) whenever: [XO, XO + XS) does not intersect [YO, YO + YS) In other words, the accesses can alias only if XB == YB at runtime. However, this doesn't cope correctly with section anchors. For example, if XB is an anchor symbol and YB is at offset XO from the anchor, then: [XB + XO, XB + XO + XS) overlaps [YB, YB + YS) whatever the value of XO is. In other words, when doing the alias check for two symbols whose local definitions are in the same block, we should apply the known difference between their block offsets to the intersection test above. gcc/ PR rtl-optimization/92294 * alias.c (compare_base_symbol_refs): Take an extra parameter and add the distance between two symbols to it. Enshrine in comments that -1 means "either 0 or 1, but we can't tell which at compile time". (memrefs_conflict_p): Update call accordingly. (rtx_equal_for_memref_p): Likewise.

2020-02-27middle-end: Fix wrong code caused by disagreemed between FRE and access path ↵Jan Hubicka1-34/+45
oracle [PR 92152] FRE is checking stores for equivalence based on their address, value and base+ref alias sets. Because ref alias set is not always the alias set of innermost type, but it may be one of refs in the access path (as decided by component_uses_parent_alias_set_from) it means that we can not really rely on the remaining part of access path to be meaningful in any way except for offset+size computation. The patch makes alias (which is used by FRE to validate transform) and tree-ssa-alias to share same logic for ending the access path relevant for TBAA. tree-ssa-alias previously ended access paths on VIEW_CONVERT_EXPR and BIT_FIELD_REF so it is not hard to wire in common predicate. However it led to additional issues (I tried to read the code quite carefully for possible extra fun, so I hope I found it all): 1) alias_component_refs_walk compares base and reference sizes to see if one access path may continue by another. This check can be confused by an union containing structure with zero sized array. In this case we no longer see the refernece to zero sized array and think that ref size is 0. In an access path there can be at most one (valid) trailing/zero sized array access, so the sizes in the access path are decreasing with the this exception. This is already handled by the logic, however the access is not expected to happen past the end of TBAA segment. I suppose this was kind of latent problem before because one can think of access path doing traling array past VIEW_CONVERT_EXPR, but since in C code we don't VCE and in non-C we don't do trailing arrays, we did not hit the problem. I fixed this by tracking if the trailing array references appearing after the end of TBAA access path and mostly punt in the second case (because we need to support kind of all type puning here). I do not think we can assume much of sanity here, in particular, we no longer know there is only one because FRE may mix things up. An exception is the walk that looks for occurence of basetype of path1 within TBAA relevant part of path2. Here we realy care about TBAA relevant parts of paths and thus do not need to give up. I broke out the logic into ends_tbaa_access_path_p to avoid duplication and to let me stick some detailed comments. This became much more complex than I originally imagined (still it is useful to make oracle both faster and more precise). Note that logic in aliasing_component_refs_walk is safe since it works on TBAA relevant segments of paths only. 2) nonoverlapping_refs_since_match_p is using TBAA only in the corner case that the paths got out of sync and re-synchronize of types of same size are found. I thus extended it to whole paths (not only TBAA relevant parts) and track if the TBAA part can be used by counting of number of TBAA relevant res on the stack. I have noticed that in one case we call nonoverlapping_refs_since_match_p before checking for view converting MEM_REFs and in others we check after. I think we want to just disable TBAA part if view convert is in there but still disambiguate. I will do this incrementaly. 3) nonoverlapping_component_refs_p uses TBAA so it needs to punt on end of TBAA path. It deals with no sizes and thus there is not the issue as in 1). I am also attaching one (most probably) valid C++ testcase (by Mark Williams) where we incorrectly disambiguated while the code is valid by the common initial sequence rule. This happens to be fixed by same patch. Here one access goes through union and follows by access path trhough one filed, while other access path start by different field of the union with common initial sequence. This made aliasing_component_refs_p to not find the overlapping type (because there is none) and disambiguate. Now we cut the first access path by the union reference and this makes us to find the path continuation in alias_component_refs_walk. If FRE is ever made more careful about access paths past the fist union reference (I think that would be good idea since unions are quite common in C++ and we throw away quite useful info) then we will need to teach access path oracle about the common initial sequence rule (which, as Mark pointed out, is part of both C and C++ standards). Only argument that can possibly invalidate this testcase is that I do not see that stadnard is clear about the situation where one access path contains the union but other starts after the union. Clearly if both start after the union reference we are right to disambiguate (since there is no union unvolved). If both starts before union then there is common initial sequence and by standard it is defined. This case works on current trunk because aliasing_component_refs_p resorts to base+offset after finding the match. But even that is more or less an accident I would say. I had to xfail three testcases. While alias-access-path ones are artificial and odd, 20030807-7 is derived from gcc and shows that we give up on disambiguations of tree_node union, so this patch disables useful transform in real world code. I am still planning to collect some data on the effect of this change to TBAA, but unless we want to reorganize FRE, I do not think there is better solution. gcc/ChangeLog: 2020-02-26 Jan Hubicka <hubicka@ucw.cz> PR middle-end/92152 * alias.c (ends_tbaa_access_path_p): Break out from ...

2019-09-09Make note_stores take an rtx_insnRichard Sandiford1-2/+3
I have a series of patches that (as a side effect) makes all rtl passes use the information collected by -fipa-ra. This showed up a latent bug in the liveness tracking in regrename.c, which doesn't take CALL_INSN_FUNCTION_USAGE into account when processing clobbers. This actually seems to be quite a common problem with passes that use note_stores; only a handful remember to walk CALL_INSN_FUNCTION_USAGE too. I think it was just luck that I saw it with regrename first. This patch tries to make things more robust by passing an insn rather than a pattern to note_stores. The old function is still available as note_pattern_stores for the few places that need it. When updating callers, I've erred on the side of using note_stores rather than note_pattern_stores, because IMO note_stores should be the default choice and we should only use note_pattern_stores if there's a specific reason. Specifically: * For cselib.c, "body" may be a COND_EXEC_CODE instead of the main insn pattern. * For ira.c, I wasn't sure whether extending no_equiv to CALL_INSN_FUNCTION_USAGE really made sense, since we don't do that for normal call-clobbered registers. Same for mark_not_eliminable in reload1.c * Some other places only have a pattern available, and since those places wouldn't benefit from walking CALL_INSN_FUNCTION_USAGE, it seemed better to alter the code as little as possible. * In the config/ changes, quite a few callers have already weeded out CALL insns. It still seemed better to use note_stores rather than prematurely optimise. (note_stores should tail call to note_pattern_stores once it sees that the insn isn't a call.)

2018-03-01Tighten use of HARD_FRAME_POINTER_REGNUM in alias.c (PR 84538)Richard Sandiford1-1/+17
RTL code needs to be consistent about whether it uses the stack pointer, the frame pointer or the argument pointer to access a given part of the frame. alias.c used this to divide accesses into three independent areas. The problem in the PR is that we did this for HARD_FRAME_POINTER_REGNUM even when the register wasn't being used as a frame pointer. We can't do that because the frame pointer is then just any old allocatable register and could certainly point to info accessed through the argument pointer or stack pointer. 2018-03-01 Richard Sandiford <richard.sandiford@linaro.org> gcc/ PR rtl-optimization/84538 * alias.c (init_alias_target): Add commentary.

The xsize and ysize arguments to memrefs_conflict_p are encode such that: - 0 means the size is unknown - >0 means the size is known - <0 means that the negative of the size is a worst-case size after alignment In other words, the sign effectively encodes a boolean; it isn't meant to be taken literally. With poly_ints these correspond to: - must_eq (..., 0) - may_gt (..., 0) - may_lt (..., 0) respectively. 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * alias.c (addr_side_effect_eval): Take the size as a poly_int64 rather than an int.

2017-12-20poly_int: SUBREG_BYTERichard Sandiford1-0/+5
This patch changes SUBREG_BYTE from an int to a poly_int. Since valid SUBREG_BYTEs must be contained within the mode of the SUBREG_REG, the required range is the same as for GET_MODE_SIZE, i.e. unsigned short. The patch therefore uses poly_uint16(_pod) for the SUBREG_BYTE. Using poly_uint16_pod rtx fields requires a new field code ('p'). Since there are no other uses of 'p' besides SUBREG_BYTE, the patch doesn't add an XPOLY or whatever; all uses should go via SUBREG_BYTE instead. The patch doesn't bother implementing 'p' support for legacy define_peepholes, since none of the remaining ones have subregs in their patterns. As it happened, the rtl documentation used SUBREG as an example of a code with mixed field types, accessed via XEXP (x, 0) and XINT (x, 1). Since there's no direct replacement for XINT, and since people should never use it even if there were, the patch changes the example to use INT_LIST instead. The patch also changes subreg-related helper functions so that they too take and return polynomial offsets. This makes the patch quite big, but it's mostly mechanical. The patch generally sticks to existing choices wrt signedness. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/rtl.texi: Update documentation of SUBREG_BYTE.

2017-12-20poly_int: MEM_OFFSET and MEM_SIZERichard Sandiford1-25/+17
This patch changes the MEM_OFFSET and MEM_SIZE memory attributes from HOST_WIDE_INT to poly_int64. Most of it is mechanical, but there is one nonbovious change in widen_memory_access. Previously the main while loop broke with: /* Similarly for the decl. */ else if (DECL_P (attrs.expr) && DECL_SIZE_UNIT (attrs.expr) && TREE_CODE (DECL_SIZE_UNIT (attrs.expr)) == INTEGER_CST && compare_tree_int (DECL_SIZE_UNIT (attrs.expr), size) >= 0 && (! attrs.offset_known_p || attrs.offset >= 0)) break; but it seemed wrong to optimistically assume the best case when the offset isn't known (and thus might be negative). As it happens, the "! attrs.offset_known_p" condition was always false, because we'd already nullified attrs.expr in that case: /* If we don't know what offset we were at within the expression, then we can't know if we've overstepped the bounds. */ if (! attrs.offset_known_p) attrs.expr = NULL_TREE; The patch therefore drops "! attrs.offset_known_p ||" when converting the offset check to the may/must interface. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * rtl.h (mem_attrs): Add a default constructor.

alias.c:find_base_term and find_base_value checked: if (GET_MODE_SIZE (GET_MODE (src)) < GET_MODE_SIZE (Pmode)) but (a) comparing the precision seems more correct, since it's possible for modes to have the same memory size as Pmode but fewer bits and (b) the functions are called on arbitrary rtl, so there's no guarantee that we're handling an integer truncation.

2016-11-15Use simplify_gen_binary in canon_rtxRichard Sandiford1-7/+1
After simplifying the operands of a PLUS, canon_rtx checked only for cases in which one of the simplified operands was a constant, falling back to gen_rtx_PLUS otherwise. This left the PLUS in a non-canonical order if one of the simplified operands was (plus (reg R1) (const_int X)); we'd end up with: (plus (plus (reg R1) (const_int Y)) (reg R2)) rather than: (plus (plus (reg R1) (reg R2)) (const_int Y)) Fixing this exposed new DSE opportunities on spu-elf in gcc.c-torture/execute/builtins/strcat-chk.c but otherwise it doesn't seem to have much practical effect. gcc/ 2016-11-15 Richard Sandiford <richard.sandiford@arm.com> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> * alias.c (canon_rtx): Use simplify_gen_binary.

2016-10-21make LABEL_REF_LABEL a rtx_insn *Trevor Saunders1-1/+1
While changing LABEL_REF_LABEL it might as well become an inline function, so that its clearer what types are involved. Unfortunately because it is still possible to use XEXP and related macros on a LABEL_REF rtx you can still set the field to be a non insn rtx. The other unfortunate thing is that the generators actually create LABEL_REF rtx that refer to MATCH_x rtx, so there we actually need to use XEXP to bypass the checking this patch adds. gcc/ChangeLog: 2016-10-21 Trevor Saunders <tbsaunde+gcc@tbsaunde.org> * rtl.h (label_ref_label): New function.
