This has two significant effects:

1) Direct relational comparisons between null pointer constants (0 and nullopt)
   and pointers are now ill-formed. This was always the case for C, and it
   appears that C++ only ever permitted by accident. For instance, cases like
     nullptr < &a
   are now rejected.

2) Comparisons and conditional operators between differently-cv-qualified
   pointer types now work, and produce a composite type that both source
   pointer types can convert to (when possible). For instance, comparison
   between 'int **' and 'const int **' is now valid, and uses an intermediate
   type of 'const int *const *'.

Li Huang [Fri, 21 Oct 2016 20:05:21 +0000 (20:05 +0000)]
[SCEV] Memoize visitMulExpr results in SCEVRewriteVisitor.

Summary:
When SCEVRewriteVisitor traverses the SCEV DAG, it may visit the same SCEV
multiple times if this SCEV is referenced by multiple other SCEVs. This has
exponential time complexity in the worst case. Memoizing the results will
avoid re-visiting the same SCEV. Add a map to save the results, and override
the visit function of SCEVVisitor. Now SCEVRewriteVisitor only visit each
SCEV once and thus returns the same result for the same input SCEV.

This patch fixes PR18606, PR18607.

7 years ago[SCEVAffinator] Make precise modular math more correct.
Eli Friedman [Fri, 21 Oct 2016 18:08:02 +0000 (18:08 +0000)]
[SCEVAffinator] Make precise modular math more correct.

Integer math in LLVM IR is modular. Integer math in isl is
arbitrary-precision. Modeling LLVM IR math correctly in isl requires
either adding assumptions that math doesn't actually overflow, or
explicitly wrapping the math. However, expressions with the "nsw" flag
are special; we can pretend they're arbitrary-precision because it's
undefined behavior if the result wraps. SCEV expressions based on IR
instructions with an nsw flag also carry an nsw flag (roughly; actually,
the real rule is a bit more complicated, but the details don't matter
here).

Before this patch, SCEV flags were also overloaded with an additional
function: the ZExt code was mutating SCEV expressions as a hack to
indicate to checkForWrapping that we don't need to add assumptions to
the operand of a ZExt; it'll add explicit wrapping itself. This kind of
works... the problem is that if anything else ever touches that SCEV
expression, it'll get confused by the incorrect flags.

Instead, with this patch, we make the decision about whether to
explicitly wrap the math a bit earlier, basing the decision purely on
the SCEV expression itself, and not its users.

keeping only the first loop test to check for the zero iteration case.

Most of the work here is in plumbing this 'max-or-zero' information from the
part of scalar evolution where it's detected through to loop unrolling. I've
also gone for the safe default of 'false' everywhere but howManyLessThans which
could probably be improved.

Revert "Fix a race condition between "ephemeral watchpoint disable/enable" and continue in commands."

This reverts commit r284795, as it breaks watchpoint handling on arm (and
presumable all architectures that report watchpoint hits without executing the
tripping instruction).

There seems to be something fundamentally wrong with this patch: it uses
process_sp->AddPreResumeAction to re-enable the watchpoint, but the whole point
of the step-over-watchpoint logic (which AFAIK is the only user of this class) is
to disable the watchpoint *after* we resume to do the single step.

I have no idea how to fix this except by reverting the offending patch.
