faisalv e6aa06545b [NFC, Refactor] Modernize the TypeSpecifierWidth enum (Specifiers.h) to a scoped enum
Reviewed here: https://reviews.llvm.org/D91409 by Aaron.
Highlights of the review:
  - avoid an underlying type for enums
  - avoid enum bit fields (MSVC packing anomalies) and favor static_casts to unsigned bit-fields

Patch by Thorsten Schuett <schuett@gmail.com> w some minor fixes in SemaType.cpp where a couple asserts had to be repaired to deal with lack of implicit coversion to int.

Thanks Thorsten!

Aaron Puchert dea31f135c Consistent spelling in diagnostics: {l,r}value instead of {l,r}-value
As Richard Smith pointed out in the review of D90123, both the C and C++
standard call it lvalue and rvalue, so let's stick to the same spelling
in Clang.

Aaron Puchert 6f84779674 [Sema] Improve notes for value category mismatch in overloading
When an overloaded member function has a ref-qualifier, like:

class X {
    void f() &&;
    void f(int) &;
};

we would print strange notes when the ref-qualifier doesn't fit the value
category:

X x;
x.f();
X().f(0);

would both print a note "no known conversion from 'X' to 'X' for object
argument" on their relevant overload instead of pointing out the
mismatch in value category.

At first I thought the solution is easy: just use the FailureKind member
of the BadConversionSequence struct. But it turns out that we weren't
properly setting this for function arguments. So I went through
TryReferenceInit to make sure we're doing that right, and found a number
of notes in the existing tests that improved as well.

Fixes PR47791.

Nikita Popov 9ace4b337f Revert "[SCEV] Factor out part of wrap flag detection logic [NFC-ish]"
This reverts commit 1ec6e1eb8a.

This change causes a significant compile-time regression:
https://llvm-compile-time-tracker.com/compare.php?from=dd0b8b94d0796bd895cc998dd163b4fbebceb0b8&to=1ec6e1eb8a084bffae8a40236eb9925d8026dd07&stat=instructions

I assume that this is due to the non-NFC part of the change, which
now performs expensive nowrap inference even for nowrap flags that
are not used by the particular code.

Philip Reames 1ec6e1eb8a [SCEV] Factor out part of wrap flag detection logic [NFC-ish]
In an effort to make code around flag determination more readable, and (possibly) prepare for a follow up change, factor out some of the flag detection logic.  In the process, reduce the number of locations we mutate wrap flags by a couple.

Note that this isn't NFC.  The old code tried for NSW xor (NUW || NW).  This is, two different paths computed different sets of wrap flags.  The new code will try for all three.  The result is that some expressions end up with a few extra flags set.

However llvm-config requires all components to be built, and the

should fix some bots in the meantime.

[NFC] Small refactor to CompilationDatabase 2020-11-14 14:03:35 +00:00
Sanjay Patel 8ec7ea3ddc [CostModel] make default size cost for libcalls small (again)
This was changed recently with D90554 / f7eac51b9b
...because we had a regression testing blindspot for intrinsics
that are expected to be lowered to libcalls.

In general, we want the *size* cost for a scalar call to be cheap
even if the other costs are expensive - we expect it to just be
a branch with some optional stack manipulation.

It is likely that we will want to carve out some
exceptions/overrides to this rule as follow-up patches for
calls that have some general and/or target-specific difference
to the expected lowering.

This was noticed as a regression in unrolling, so we have a test
for that now along with a couple of direct cost model tests.

If the assumed scalarization costs for the oversized vector
calls are not realistic, that would be another follow-up
refinement of the cost models.

Revert "clang-misexpect: Profile Guided Validation of Performance Annotations in LLVM"
See discussion in https://bugs.llvm.org/show_bug.cgi?id=45073 / https://reviews.llvm.org/D66324#2334485
the implementation is known-broken for certain inputs,
the bugreport was up for a significant amount of timer,
and there has been no activity to address it.
Therefore, just completely rip out all of misexpect handling.

I suspect, fixing it requires redesigning the internals of MD_misexpect.
Should anyone commit to fixing the implementation problem,
starting from clean slate may be better anyways.

This reverts commit 7bdad08429,
and some of it's follow-ups, that don't stand on their own.

Mehdi Amini 42e88bd6b1 Replace sequences of v.push_back(v[i]); v.erase(&v[i]); with std::rotate (NFC)
The code has a few sequence that looked like:

    Ops.push_back(Ops[0]);
    Ops.erase(Ops.begin());

And are equivalent to:

    std::rotate(Ops.begin(), Ops.begin() + 1, Ops.end());

The latter has the advantage of never reallocating the vector, which
would be a bug in the original code as push_back would read from the
memory it deallocated.
