* It renames TTI.emitActiveLaneMask() to TTI.getPreferredTailFoldingStyle()
* Simplifies some of its uses in the LoopVectorizer

Rationale: To my surprise PredicationStyle::None did not mean 'no
predication', but rather 'no active lane mask intrinsic', such that the
predicate is created using a splat + compare with stepvector. The enum is
also highly specific to tail folding, so it seems better to name this
around that feature, i.e. 'tail folding style'.

This also makes it more amenable to extend it to other tail folding styles,
such as the one added in D142109.

18 months ago[dsymutil] dsymutil produces broken lines info (probably) with LTO on mac
Alexey Lapshin [Mon, 30 Jan 2023 14:05:53 +0000 (15:05 +0100)]
[dsymutil] dsymutil produces broken lines info (probably) with LTO on mac

This patch fixes #60307 issue. The 8bb4451 introduces the possibility
to unite overlapped or adjacent address ranges to keep address ranges
in an unambiguous state. The AddressRangesMap is used to normalize
address ranges. The AddressRangesMap keeps address ranges and the value
of the relocated address. For intersected range, it creates a united
range that keeps the last inserted mapping value. The same for adjusted ranges.
While it is OK to use the last inserted mapping value for intersected ranges
(as there is no way how to resolve ambiguity) It is not OK to use the
last inserted value for adjacent address ranges. Currently, two following
address ranges are united into a single one:

{0,24,17e685c} {24,d8,55afe20} -> {0,d8,55afe20}

To avoid the problem, the AddressRangesMap should not unite adjacent address ranges
with different relocated addresses. Instead, it should leave adjacent address ranges
as separate ranges. So, the ranges should look like this:

{0,24,17e685c} {24,d8,55afe20}

[C++20] [Modules] Pop Expression Evaluation Context when we skip its body during parsing

Close https://github.com/llvm/llvm-project/issues/60275

The root cause of issue 60275 is the imbalance of
PushExpressionEvaluationContext() and PopExpressionEvaluationContext().

See
https://github.com/llvm/llvm-project/blob/f1c4f927f7c15b5efdc3589c050fd0513bf6b303/clang/lib/Parse/Parser.cpp#L1396-L1437

We will PushExpressionEvaluationContext() in ActOnStartOfFunctionDef()
in line 1396 and we should pop it in ActOnFinishFunctionBody later.
However if we skip the function body in line 1402, the expression
evaluation context will not be popped. Then here is the issue report. I
fix the issue by inserting codes to pop the expression evaluation
context explicitly if the function body is skipped. Maybe this looks
like an ad-hoc fix. But if we want to fix this in a pretty way, we
should refactor the current framework for pushing and popping expression
evaluation contexts. Currently there are 23
PushExpressionEvaluationContext() callsities and 21
PopExpressionEvaluationContext() callsites in the code. And it seems not
easy to balance them well and fast. So I suggest to land this fix first.
At least it can prevent the crash.

Fix a non-deterministic issue in clang module generation, which the
anonymous declaration number from a function context is not
deterministic. This is due to the unstable iteration order for decls in
scope so the order after moving the decls into function decl context is
not deterministic.

From https://reviews.llvm.org/D135118, we can't use a set that preserves
the order without the performance penalty. Fix the issue by sorting the
decls based on raw encoding of their source location.
