Arnold Schwaighofer 12b0d1cda0 LoopVectorize: Make Value pointers that could be RAUW'ed a VH
The Value pointers we store in the induction variable list can be RAUW'ed by a
call to SCEVExpander::expandCodeFor, use a TrackingVH instead. Do the same thing
in some other places where we store pointers that could potentially be RAUW'ed.

Fixes PR16073.

Manuel Klimek 4fe43002f8 Makes whitespace management more consistent.
Instead of selectively storing some changes and directly generating
replacements for others, we now notify the WhitespaceManager of the
whitespace before every token (and optionally with more changes inside
tokens).

Then, we run over all whitespace in the very end in original source
order, where we have all information available to correctly align
comments and escaped newlines.

The future direction is to pull more of the comment alignment
implementation that is now in the BreakableToken into the
WhitespaceManager.

This fixes a bug when aligning comments or escaped newlines in unwrapped
lines that are handled out of order:
  #define A \
    f({     \
      g();  \
    });
... now gets correctly layouted.

Richard Sandiford 03528f346a [SystemZ] Fix thinko in long branch pass
The original version of the pass could underestimate the length of a backward
branch in cases like:

    alignment to N bytes or more
    ...
    relaxable branch A
    ...
 foo: (aligned to M<N bytes)
    ...
 bar: (aligned to N bytes)
    ...
    relaxable branch B to foo

We don't add any misalignment gap for "bar" because N bytes of alignment
had already been reached earlier in the function.  In this case, assuming
that A is relaxed can push "foo" closer to "bar", and make B appear to be
in range.  Similar problems can occur for forward branches.

I don't think it's possible to create blocks with mixed alignments as
things stand, not least because we haven't yet defined getPrefLoopAlignment()
for SystemZ (that would need benchmarking).  So I don't think we can test
this yet.

Thanks to Rafael Espíndola for spotting the bug.

Daniel Jasper a4c571cd1c Improve clang-format's stream formatting.
clang-format was a bit too aggressive when trying to keep labels and
values on the same line.

Before:
    llvm::outs()
         << "aaaaaaaaaaaaaaaaaaa: " << aaaaaaaaaaaaa(
                                           aaaaaaaaaaaaaaaaaaaaaaaaaaaa);
After:
  llvm::outs() << "aaaaaaaaaaaaaaaaaaa: "
               << aaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaa);

Daniel Jasper 53e8d854fd Fix function declaration behavior.
This only affects styles that prevent bin packing. There, a break after
a template declaration also forced a line break after the function name.

Before:
template <class SomeType, class SomeOtherType>
SomeType
SomeFunction(SomeType Type, SomeOtherType OtherType) {}

After:
template <class SomeType, class SomeOtherType>
SomeType SomeFunction(SomeType Type, SomeOtherType OtherType) {}

This fixes llvm.org/PR16072.

Daniel Jasper f8114cf621 Cut-off clang-format analysis.
If clang-format is confronted with long and deeply nested lines (e.g.
complex static initializers or function calls), it can currently try too
hard to find the optimal solution and never finish. The reason is that
the memoization does not work effectively for deeply nested lines.

This patch removes an earlier workaround and instead opts for
accepting a non-optimal solution in rare cases. However, it only does
so only in cases where it would have to analyze an excessive number of
states (currently set to 10000 - the most complex line in Format.cpp
requires ~800 states) so this should not change the behavior in a
relevant way.
