Summary:
This introduces new flag to the update_test_checks and
update_cc_test_checks that allows for function attributes
to be checked in a check-line. If the flag is not set,
the behavior should remain the same.

In clang <3.9 the `unique_ptr` constructor that is supposed to allow
for Derived to Base conversion does not work. Remove this if we drop
support for such configurations.
This is the same fix as in fda901a987, and it updates the comments
to better reflect the actual issue. The same thing reproduces with
libc++ with older clangs.
This is a workaround for a bug in older versions of Clang when. The
constructor that is supposed to allow for Derived to Base conversion
does not work. Remove this if we drop support for such configurations.
sync_source_lists_from_cmake now also looks for source files in
`sources += [ "foo.cc" ]` lines, which allows us to remove most
`# Make `gn format` not collapse this` comments.
(sync_source_lists_from_cmake doesn't look for `foo_headers += [...]`
still, so the comment is still needed in two places for that.)
No intentional behavior change.
This gives a nice error if you accidentally try to use an empty list for
the RegTypes of a RegisterClass.

The size of VTList that is pushed into this container is usually 1, but
often 6 or 7. Change the vector to SmallVector to eliminate frequent
mallocs. This happens hundreds of thousands of times in each tablegen
execution during the LLVM/clang build.

Instead of detecting it automatically but also allowing for the setting
to be specified explicitly, always detect whether exceptions are enabled
based on whether -fno-rtti (or equivalent) is used. It's less confusing
to have a single way of tweaking that knob.
This change follows the lead of 71d88cebfb.
Currently custom code predicates can only really be used for
contextless checks tied to a single instruction (e.g. check the def
for hasOneUse). If you do want to inspect the input instructions in
the source pattern, you cannot without re-verifying the opcode and
type checks implied by the patterns, since this check was emitted
before any operand constraints. Really, these are pattern level
predicates that implicitly depend on the instruction and operand
checks.
Introduce a filtering function so the custom predicate is emitted
last. I'm not sure this is the most elegant solution. It seems like
this is really a different thing from the InstructionMatcher/IPM_
predicate kinds. I initially tried keeping this in a separate
predicate list, but that also seemed awkward.
This only half fixes the problem I'm trying to solve. The AMDGPU
pattern I'm attempting to port also uses the PredicateCodeUsesOperands
feature to allow checks on the source operands when the input pattern
is commuted. Really the emitter should reject the pattern since it
doesn't handle this case, but at this point it would be more
productive to just implement this.
As per discussion in D69207, have lit ignore UnicodeDecodeErrors
when running with python 2 in an ASCII shell.

This can be run after a ninja-based build, and analyzes the ninja

This was emitting the raw value for the reg class ID with a comment
for the actual class name. Switch to emitting the qualified enum name
instead, which obviates the need for the comment and also helps keep
the lit tests on the emitter output more stable.
Summary:
This patch is enabling the generation of clauses enum sets for semantics check in Flang through
tablegen. Enum sets and directive - sets map is generated by the new tablegen infrsatructure for OpenMP

The semantic checks for OpenMP are modified to use this newly generated map.

In FileCheck.rst, add `-dump-input-context` and `-dump-input-filter`,
and fix some `-dump-input` documentation.
In `FileCheck -help`, `cl::value_desc("kind")` is being ignored for
`-dump-input-filter`, so just drop it.
Extend `-dump-input=help` to mention FILECHECK_OPTS.
This makes the input dump filtering implemented by D82203 more
configurable. D82203 enables filtering out everything but the initial
input lines of error diagnostics (plus some context). This patch
enables including any line with any kind of annotation.

When input is dumped as specified by `-dump-input=fail`, this patch
filters the dump to show only input lines that are the starting lines
of error diagnostics plus the number of contextual lines specified
`-dump-input-context` (defaults to 5).
When `-dump-input=always`, there might be not be any errors, so all
input lines are printed, as without this patch.

This fixes the build of compiler-rt on macOS when _not_ using
clang_base_path in args.gn: Xcode clang knows where to find the
SDK, but regular clang doesn't and needs a -isysroot parameter.
We correctly add that parameter when clang_base_path is set,
but else we omit it. If clang_base_path was not set, we also
didn't add the flag for stage2_unix_toolchain() when we build
compiler-rt with just-built clang.
Make stage2_unix_toolchain() use clang_base_path instead of setting
cc / cxx. It's less code, and it gets things like this right.
Instead of detecting it automatically (in libc++) and relying on
_LIBCXXABI_NO_EXCEPTIONS being set explicitly (in libc++abi), always
detect whether exceptions are enabled automatically.
This commit also removes support for specifying -D_LIBCPP_NO_EXCEPTIONS
and -D_LIBCXXABI_NO_EXCEPTIONS explicitly -- those should just be inferred
from using -fno-exceptions (or an equivalent flag).
Allowing both -D_FOO_NO_EXCEPTIONS to be provided explicitly and trying
to detect it automatically is just confusing, especially since we did
specify it explicitly when building libc++abi. We should have only one
way to detect whether exceptions are enabled, but it should be robust.
Summary:
Follow up to D81736. Move getOpenMPDirectiveKind, getOpenMPClauseKind, getOpenMPDirectiveName and
getOpenMPClauseName to the new tablegen code generation. The code is generated in a new file named OMP.cpp.inc

In RISC-V vector extension, users could group multiple vector registers
as one pseudo register. In mixed width operations, users could use
partial vector registers to reduce the register pressure. The parameter
to control register grouping and partial use is called LMUL. LMUL is a
part of the type. So, we have a bunch of vector types. In order to
support all these types, we need new MVT types in LLVM. In this patch, I
added several MVT types that are used in RISC-V vector implementation.
This is a standalone patch for MVT types without RISC-V related implementation.

`FILECHECK_OPTS` was implemented so that a test runner, such as CI,
can specify FileCheck debugging options, such as `-v` and `-vv`.
However, if a test suite has a FileCheck call that already specifies
`-v` or `-vv`, then that call will fail if `FILECHECK_OPTS` also
specifies it.
For `-vv`, this problem already exists:
`clang/test/CodeGen/aarch64-v8.2a-fp16-intrinsics-constrained.c`
It's not yet clear if the `-vv` in that test was intentional, but this
usage shouldn't fail anyway. It's already true that FileCheck permits
`-vv` and `-v` together even though `-vv` implies `-v`.
Compare D70784, which fixed the same problem for `-dump-input`.
