Turn it into a variant class instead. This conversion does indeed save some code
but there's a plan to add support for more kinds of terminators that aren't
necessarily based on statements, and with those in mind it becomes more and more
confusing to have CFGTerminators implicitly convertible to a Stmt *.

Summary:
On Windows, X8 may be used to pass in the address of an aggregate that
is returned indirectly. Therefore, it should be forwarded to variadic
musttail calls and preserved in thunks.

This test case was incorrect because it mixed DWARF32 and DWARF64 for a
single unit (DWARF32 unit referencing a DWARF64 str_offsets section). So
fix enough of the unit parsing for DWARF64 and make the test valid.
(not sure if anyone needs DWARF64 support though - support in
libDebugInfoDWARF has been added piecemeal and LLVM doesn't produce it
at all)

Without this, sectionWithinSegment() will return the wrong answer for bss

Summary:
This provides the `std::destroying_delete_t` declaration in C++2a and after. (Even when the compiler doesn't support the language feature).
However, the feature test macro `__cpp_lib_destroying_delete` is only defined when we have both language support and C++2a.

Summary:
For the most part this consists of replacing ${LLVM_TARGETS_TO_BUILD} with
some combination of AllTargets* so that they depend on specific components
of a target backend rather than all of it. The overall effect of this is
that, for example, tools like opt no longer falsely depend on the
disassembler, while tools like llvm-ar no longer depend on the code
generator.
There's a couple quirks to point out here:
* AllTargetsCodeGens is a bit more prevalent than expected. Tools like dsymutil
seem to need it which I was surprised by.
* llvm-xray linked to all the backends but doesn't seem to need any of them.
It builds and passes the tests so that seems to be correct.
* I left gold out as it's not built when binutils is not available so I'm
unable to test it

If the variable is a firstprivate variable and it was not emitted beause

uses --implicit-check-not to verify that certain patterns do not occur
in llvm-objdump's output, except in places where they are explicitly
checked. Unfortunately, the patterns are generic enough that they may
be part of the file name which is also output by llvm-objdump. This
change matches the line with the filename explicitly so that the
implicit patterns are not applied to it.

Previously, the only way to display the list of available checkers was
to invoke the analyzer with -analyzer-checker-help frontend flag. This
however wasn't really great from a maintainer standpoint: users came
across checkers meant strictly for development purposes that weren't to
be tinkered with, or those that were still in development. This patch
creates a clearer division in between these categories.
From now on, we'll have 3 flags to display the list checkers. These
lists are mutually exclusive and can be used in any combination (for
example to display both stable and alpha checkers).
-analyzer-checker-help: Displays the list for stable, production ready
checkers.
-analyzer-checker-help-alpha: Displays the list for in development
checkers. Enabling is discouraged
for non-development purposes.
-analyzer-checker-help-developer: Modeling and debug checkers. Modeling
checkers shouldn't be enabled/disabled
by hand, and debug checkers shouldn't
be touched by users.

This is no-functional-change-intended currently because the definition
of isBinOp() only includes opcodes that produce 1 value. But if we
share that implementation with isCommutativeBinOp() as proposed in
D62191, then we need to make sure that the callers bail out for
opcodes that they are not prepared to handle correctly.
llvm-svn: 361547
The copy constructor of RegularExpression doesn't initialize m_comp_err. This causes an use-of-initialized-value error when a RegularExpression is copied: the copy constructor calls Compile, which calls Free to free the existing regex if needed, which in turn reads m_comp_err to check if there's any regex to be freed.
This change calls the default constructor from the other constructors to make sure members are always initialized with sensible values. This also avoids duplicating init logic, like the RegularExpression(llvm:StringRef) constructor does, which is error prone.

We were assuming a much larger possible per-wave visible stack
allocation than is possible:
faa3ae5138/src/core/runtime/amd_gpu_agent.cpp (L70)
Based on this, we can assume the high 15 bits of a frame index or sret
are 0. The frame index value is the per-lane offset, so the maximum
frame index value is MAX_WAVE_SCRATCH / wavesize.
Remove the corresponding subtarget feature and option that made
this configurable.

The refactoring in r360276 moved the `RunSLPVectorization` flag and added the default explicitly. The default should have been `false`, as before.
The new pass manager used to have SLPVectorization on by default, now it's off in opt, and needs D61617 checked in to enable it in clang.
