Once all test and benchmark reports look good, merge the backports branch into + the corresponding release branch (e.g. merge `backports-release-1.6` into + `release-1.6`). + +5.

[PATCH] Fix table indexing in `dwarf_search_unwind_table` + +`table_len` is used as an index into `table`, assuming it represents the +number of entries. However, it is defined as the number of entries +multiplied by `sizeof(unw_word_t)`. This is accounted for in other +places that use `table_len`, e.g. in `lookup`, which divides out the +size of `unw_word_t`, but the indexing expression uses `table_len` +directly. So when `table` has say 2 entries, we're actually looking at +index 15 rather than 1 in the comparison.

However, that obviously -relies on the expander knowing what the type of the SCEV expression is. -That is usually the case, but there is one important case where it's -not: The type of an add expression is just the type of the last operand, -so if the non-integral pointer is not the last operand, later uses of -that SCEV may not realize that the given add expression contains -non-integral pointers and may try to expand it as integers. - -One interesting observation is that we do get away with this scheme in -shockingly many cases. The reason for this is that SCEV expressions -often have an `scUnknown` pointer base, which our sort order on the -operands of add expressions sort behind basically everything else, -so it usually ends up as the last operand. - -One situation where this fails is included as a test case. This test -case was bugpoint-reduced from the issue reported at -https://github.com/JuliaLang/julia/issues/31156. What happens here -is that the pointer base is an scAddRec from an outer loop, plus an -scUnknown integer offset. By our sort order, the scUnknown gets sorted -after the scAddRec pointer base, thus making an add expression of these -two operands have integer type. This then confuses the expander, into -attempting to expand the whole thing as integers, which will obviously -fail when reaching the non-integral pointer. - -I considered a few options to solve this, but here's what I ended up -settling on: The AddExpr class gains a new subclass that explicitly -stores the type of the expression. This subclass is used whenever one -of the operands is a non-integral pointer. To reduce the impact for the -regular case (where the SCEV expression contains no non-integral -pointers), a bit flag is kept in each flag expression to indicate -whether it is of non-integral pointer type (this should give the same -answer as asking if getType() is non-integral, but performing that -query may involve a pointer chase and requires the DataLayout). For -add expressions that flag is also used to indicate whether we're using -the subclass or not. This is slightly inefficient, because it uses -the subclass even in the (not uncommon) case where the last operand -does actually accurately reflect the non-integral pointer type. However, -it didn't seem worth the extra flag bit and complexity to do this -micro-optimization. - -I had hoped that we could additionally restrict mul exprs from -containing any non-integral pointers, and also require add exprs to -only have one operand containg such pointers (but not more), but this -turned out not to work. The reason for this is that SCEV wants to -form differences between pointers, which it represents as `A + B*-1`, -so we need to allow both multiplication by `-1` and addition with -multiple non-integral pointer arguments. I'm not super happy with -that situation, but I think it exposes a more general problem with -non-integral pointers in LLVM. We don't actually have a way to express -the difference between two non-integral pointers at the IR level. -In theory this is a problem for SCEV, because it means that we can't -materialize such SCEV expression. However, in practice, these -expressions generally have the same base pointer, so SCEV will -appropriately simplify them to just the integer components. -Nevertheless it is a bit unsatisfying. Perhaps we could have an -intrinsic that takes the byte difference between two pointers to the -same allocated object (in the same sense as is used in getelementptr), -which should be a sensible operation even for non-integral pointers. -However, given the practical considerations above, that's a project -for another time. For now, simply allowing the existing pointer-diff -pattern for non-integral pointers seems to work ok. - -Differential Revision: https://reviews.llvm.org/D75072 ---- - llvm/include/llvm/Analysis/ScalarEvolution.h | 21 ++++- - .../Analysis/ScalarEvolutionExpressions.h | 81 ++++++++++++++++--- - llvm/lib/Analysis/ScalarEvolution.cpp | 41 +++++++--- - .../LoopStrengthReduce/nonintegral.ll | 35 +++++++- - 4 files changed, 155 insertions(+), 23 deletions(-) - -diff --git llvm/include/llvm/Analysis/ScalarEvolution.h llvm/include/llvm/Analysis/ScalarEvolution.h -index b3f199de2cfa..d98fbeb5dcf7 100644 ---- llvm/include/llvm/Analysis/ScalarEvolution.h -+++ llvm/include/llvm/Analysis/ScalarEvolution.h -@@ -120,6 +120,19 @@ public: - NoWrapMask = (1 << 3) - 1 - }; - -+ /// HasNonIntegralPointerFlag are bitfield indices into SubclassData. -+ /// -+ /// When constructing SCEV expressions for LLVM expressions with non-integral -+ /// pointer types, some additional processing is required to ensure that we -+ /// don't introduce any illegal transformations.

Over the past several years, we - have gradually improved the SCEVExpander to actually do something - sensible for non-integral pointer types. However, that obviously - relies on the expander knowing what the type of the SCEV expression is. - That is usually the case, but there is one important case where it's - not: The type of an add expression is just the type of the last operand, - so if the non-integral pointer is not the last operand, later uses of - that SCEV may not realize that the given add expression contains - non-integral pointers and may try to expand it as integers. - - One interesting observation is that we do get away with this scheme in - shockingly many cases. The reason for this is that SCEV expressions - often have an `scUnknown` pointer base, which our sort order on the - operands of add expressions sort behind basically everything else, - so it usually ends up as the last operand. - - One situation where this fails is included as a test case. This test - case was bugpoint-reduced from the issue reported at - https://github.com/JuliaLang/julia/issues/31156. What happens here - is that the pointer base is an scAddRec from an outer loop, plus an - scUnknown integer offset. By our sort order, the scUnknown gets sorted - after the scAddRec pointer base, thus making an add expression of these - two operands have integer type. This then confuses the expander, into - attempting to expand the whole thing as integers, which will obviously - fail when reaching the non-integral pointer. - - I considered a few options to solve this, but here's what I ended up - settling on: The AddExpr class gains a new subclass that explicitly - stores the type of the expression. This subclass is used whenever one - of the operands is a non-integral pointer. To reduce the impact for the - regular case (where the SCEV expression contains no non-integral - pointers), a bit flag is kept in each flag expression to indicate - whether it is of non-integral pointer type (this should give the same - answer as asking if getType() is non-integral, but performing that - query may involve a pointer chase and requires the DataLayout). For - add expressions that flag is also used to indicate whether we're using - the subclass or not. This is slightly inefficient, because it uses - the subclass even in the (not uncommon) case where the last operand - does actually accurately reflect the non-integral pointer type. However, - it didn't seem worth the extra flag bit and complexity to do this - micro-optimization. - - I had hoped that we could additionally restrict mul exprs from - containing any non-integral pointers, and also require add exprs to - only have one operand containg such pointers (but not more), but this - turned out not to work. The reason for this is that SCEV wants to - form differences between pointers, which it represents as `A + B*-1`, - so we need to allow both multiplication by `-1` and addition with - multiple non-integral pointer arguments. I'm not super happy with - that situation, but I think it exposes a more general problem with - non-integral pointers in LLVM. We don't actually have a way to express - the difference between two non-integral pointers at the IR level. - In theory this is a problem for SCEV, because it means that we can't - materialize such SCEV expression. However, in practice, these - expressions generally have the same base pointer, so SCEV will - appropriately simplify them to just the integer components. - Nevertheless it is a bit unsatisfying. Perhaps we could have an - intrinsic that takes the byte difference between two pointers to the - same allocated object (in the same sense as is used in getelementptr), - which should be a sensible operation even for non-integral pointers. - However, given the practical considerations above, that's a project - for another time. For now, simply allowing the existing pointer-diff - pattern for non-integral pointers seems to work ok. - - Reviewers: sanjoy, reames, vtjnash, vchuravy - - Subscribers: hiraditya, javed.absar, llvm-commits - - Tags: #llvm - - Differential Revision: https://reviews.llvm.org/D75072 - -diff --git llvm/include/llvm/Analysis/ScalarEvolution.h llvm/include/llvm/Analysis/ScalarEvolution.h -index 0bd98ef37e7..317bdeac3f0 100644 ---- llvm/include/llvm/Analysis/ScalarEvolution.h -+++ llvm/include/llvm/Analysis/ScalarEvolution.h -@@ -118,6 +118,19 @@ public: - NoWrapMask = (1 << 3) - 1 - }; - -+ /// HasNonIntegralPointerFlag are bitfield indices into SubclassData. -+ /// -+ /// When constructing SCEV expressions for LLVM expressions with non-integral -+ /// pointer types, some additional processing is required to ensure that we -+ /// don't introduce any illegal transformations.
