Yitzhak Mandelbaum c359f9537f [AST Matchers] Restrict `optionally` matcher to a single argument.
Summary:
Currently, `optionally` can take multiple arguments, which commits it to a
particular strategy for those arguments (in this case, "for each"). We limit the
matcher to a single argument, which avoids any potential confusion and
simplifies the implementation. The user can retrieve multiple-argument
optionality, by explicitly using the desired operator (like `forEach`, `anyOf`,
`allOf`, etc.) with all children wrapped in `optionally`.

Adrian Prantl 314b9278f0 Revert "[CGBlocks] Improve line info in backtraces containing *_helper_block"
Block copy/destroy helpers are now linkonce_odr functions, meant to be uniqued, and thus attaching debug information from one translation unit (or even just from one instance of many inside one translation unit) would be misleading and wrong in the general case.

selected the default mode to be non-IEEE based on the flags or based
on its true behavior, but we don't know which is the case. Since the
only users of a non-IEEE mode without a flag still support IEEE mode,
just reset to IEEE.

The output of subprocess.check_output is decode()'d through the rest of
this python program, but one appears to have been missed for the output
of the call to "clang -print-file-name=include".

On Windows, with Python 3.6, this leads to the 'args' array being a mix of

This change includes:
 - NFCi change all uses of the CallExpr to CallEvent
 - NFC rename some functions, mark static them etc.
 - NFC omit explicit TaintPropagationRule type in switches
 - NFC apply some clang-tidy fixits

Simon Tatham 068b2f313c [ARM,MVE] Add the `vshlcq` intrinsics.
Summary:
The VSHLC instruction performs a left shift of a whole vector register
by an immediate shift count up to 32, shifting in new bits at the low
end from a GPR and delivering the shifted-out bits from the high end
back into the same GPR.

Since the instruction produces two outputs (the shifted vector
register and the output GPR of shifted-out bits), it has to be
instruction-selected in C++ rather than Tablegen.

Simon Tatham 810127f6ab [ARM,MVE] Add the `vsbciq` intrinsics.
Summary:
These are exactly parallel to the existing `vadciq` intrinsics, which
we implemented last year as part of the original MVE intrinsics
framework setup.

Just like VADC/VADCI, the MVE VSBC/VSBCI instructions deliver two
outputs, both of which the intrinsic exposes: a modified vector
register and a carry flag. So they have to be instruction-selected in
C++ rather than Tablegen. However, in this case, that's trivial: the
same C++ isel routine we already have for VADC works unchanged, and
all we have to do is to pass it a different instruction id.

Summary:
This patch introduces the `clang_analyzer_isTainted` expression inspection
check for checking taint.

Using this we could query the analyzer whether the expression used as the

(like the `debug.TaintTest` would do) but only for certain expressions.

Example usage:

```lang=c++
int read_integer() {
  int n;
  clang_analyzer_isTainted(n);     // expected-warning{{NO}}
  scanf("%d", &n);
  clang_analyzer_isTainted(n);     // expected-warning{{YES}}
  clang_analyzer_isTainted(n + 2); // expected-warning{{YES}}
  clang_analyzer_isTainted(n > 0); // expected-warning{{YES}}
  int next_tainted_value = n; // no-warning
  return n;
}

Sjoerd Meijer 0a9fc9233e [Driver] Default to -fno-common for all targets
This makes -fno-common the default for all targets because this has performance
and code-size benefits and is more language conforming for C code.
Additionally, GCC10 also defaults to -fno-common and so we get consistent
behaviour with GCC.

With this change, C code that uses tentative definitions as definitions of a
variable in multiple translation units will trigger multiple-definition linker
errors. Generally, this occurs when the use of the extern keyword is neglected
in the declaration of a variable in a header file. In some cases, no specific
translation unit provides a definition of the variable. The previous behavior
can be restored by specifying -fcommon.

As GCC has switched already, we benefit from applications already being ported
and existing documentation how to do this. For example:
- https://gcc.gnu.org/gcc-10/porting_to.html
- https://wiki.gentoo.org/wiki/Gcc_10_porting_notes/fno_common

Sanjay Patel 1e308452bf [CodeGen] avoid running the entire optimizer pipeline in clang test file; NFC
I'm making the CHECK lines vague enough that they pass at -O0.
If that is too vague (we really want to check the data flow
to verify that the variables are not mismatched, etc), then
we can adjust those lines again to more closely match the output
at -O0 rather than -O1.

This change is based on the post-commit comments for:

Simon Tatham b08d2ddd69 [ARM,MVE] Add ACLE intrinsics for VCVT.F32.F16 family.
Summary:
These instructions make a vector of `<4 x float>` by widening every
other lane of a vector of `<8 x half>`.

I wondered about representing these using standard IR, along the lines
of a shufflevector to extract elements of the input into a `<4 x half>`
followed by an `fpext` to turn that into `<4 x float>`. But it looks as
if that would take a lot of work in isel lowering to make it match any
pattern I could sensibly write in Tablegen, and also I haven't been
able to think of any other case where that pattern might be generated
in IR, so there wouldn't be any extra code generation win from doing
it that way.

Therefore, I've just used another target-specific intrinsic. We can
always change it to the other way later if anyone thinks of a good
reason.

(In order to put the intrinsic definition near similar things in
`IntrinsicsARM.td`, I've also lifted the definition of the
`MVEMXPredicated` multiclass higher up the file, without changing it.)

Simon Tatham a41ecf0eb0 [ARM,MVE] Add ACLE intrinsics for VQMOV[U]N family.
Summary:
These instructions work like VMOVN (narrowing a vector of wide values
to half size, and overwriting every other lane of an output register
with the result), except that the narrowing conversion is saturating.
They come in three signedness flavours: signed to signed, unsigned to
unsigned, and signed to unsigned. All are represented in IR by a
target-specific intrinsic that takes two separate 'unsigned' flags.

Vedant Kumar dd1ea9de2e Reland: [Coverage] Revise format to reduce binary size
Try again with an up-to-date version of D69471 (99317124 was a stale
revision).

---

Revise the coverage mapping format to reduce binary size by:

1. Naming function records and marking them `linkonce_odr`, and
2. Compressing filenames.

This shrinks the size of llc's coverage segment by 82% (334MB -> 62MB)
and speeds up end-to-end single-threaded report generation by 10%. For
reference the compressed name data in llc is 81MB (__llvm_prf_names).

Rationale for changes to the format:

- With the current format, most coverage function records are discarded.
  E.g., more than 97% of the records in llc are *duplicate* placeholders
  for functions visible-but-not-used in TUs. Placeholders *are* used to
  show under-covered functions, but duplicate placeholders waste space.

- We reached general consensus about giving (1) a try at the 2017 code
  coverage BoF [1]. The thinking was that using `linkonce_odr` to merge
  duplicates is simpler than alternatives like teaching build systems
  about a coverage-aware database/module/etc on the side.

- Revising the format is expensive due to the backwards compatibility
  requirement, so we might as well compress filenames while we're at it.
  This shrinks the encoded filenames in llc by 86% (12MB -> 1.6MB).

See CoverageMappingFormat.rst for the details on what exactly has
changed.

Fixes PR34533 [2], hopefully.

Hiroshi Yamauchi f16d2bec40 Devirtualize a call on alloca without waiting for post inline cleanup and next DevirtSCCRepeatedPass iteration.
This aims to fix a missed inlining case.

If there's a virtual call in the callee on an alloca (stack allocated object) in
the caller, and the callee is inlined into the caller, the post-inline cleanup
would devirtualize the virtual call, but if the next iteration of
DevirtSCCRepeatedPass doesn't happen (under the new pass manager), which is
based on a heuristic to determine whether to reiterate, we may miss inlining the
devirtualized call.

This enables inlining in clang/test/CodeGenCXX/member-function-pointer-calls.cpp.

Joe Turner b26c88e3c6 [clang-tidy] Store all ranges in clang::tooling::Diagnostic
Summary: Instead of dropping all the ranges associated with a Diagnostic when
converting them to a ClangTidy error, instead attach them to the ClangTidyError,
so they can be consumed by other APIs.

Reid Kleckner bc8836651f Forward declare FileEntry and DirectoryEntry in Module.h
FileManager.h is an expensive header (~350ms for me in isolation), so
try to do without it.

Notably, we need to avoid checking the alignment of FileEntry, which
happens for DenseMap<FileEntry*> and PointerUnion<FileEntry*>. I
adjusted the code to avoid PointerUnion, and moved the DenseMap
insertion to the .cpp file.

Globally, this only saved about ~17 includes of the related headers
because SourceManager.h still includes FileManager.h, and it is more
popular than Module.h.

John Brawn 75d4d4bd02 Add an attribute registry so plugins can add attributes
When constructing a ParsedAttr the ParsedAttrInfo gets looked up in the
AttrInfoMap, which is auto-generated using tablegen. If that lookup fails then
we look through the ParsedAttrInfos that plugins have added to the registry and
check if any has a spelling that matches.
