by thakis[lld/mac] Add --reproduce option
This adds support for ld.lld's --reproduce / lld-link's /reproduce:
flag to the MachO port. This flag can be added to a link command
to make the link write a tar file containing all inputs to the link
and a response file containing the link command. This can be used
to reproduce the link on another machine, which is useful for sharing
bug report inputs or performance test loads.
Since the linker is usually called through the clang driver and
adding linker flags can be a bit cumbersome, setting the env var
`LLD_REPRODUCE=foo.tar` triggers the feature as well.
The file response.txt in the archive can be used with
`ld64.lld.darwinnew $(cat response.txt)` as long as the contents are
smaller than the command-line limit, or with `ld64.lld.darwinnew
@response.txt` once D92149 is in.
The support in this patch is sufficient to create a tar file for
Chromium's base_unittests that can link after unpacking on a different
machine.

by pctammela[LLDB/Lua] add support for one-liner breakpoint callback
These callbacks are set using the following:
breakpoint command add -s lua -o "print('hello world!')"
The user supplied script is executed as:
function (frame, bp_loc, ...)
<body>
end
So the local variables 'frame', 'bp_loc' and vararg are all accessible.
Any global variables declared will persist in the Lua interpreter.
A user should never hold 'frame' and 'bp_loc' in a global variable as
these userdatas are context dependent.

by spatel[IR][LoopRotate] avoid leaving phi with no operands (PR48296)
https://llvm.org/PR48296 shows an example where we delete all of the operands
of a phi without actually deleting the phi, and that is currently considered
invalid IR. The reduced test included here would crash for that reason.
A suggested follow-up is to loosen the assert to allow 0-operand phis
in unreachable blocks.

e0e7bbeb545516c50a0354efc34d329453558c9c
by Raphael Isemann[lldb] Always include template arguments that have their default value in the internal type name
Our type formatters/summaries match on the internal type name we generate in LLDB for Clang types.
These names were generated using Clang's default printing policy. However Clang's
default printing policy got tweaked over the last month to make the generated type
names more readable (by for example excluding inline/anonymous namespaces and
removing template arguments that have their default value). This broke the formatter
system where LLDB's matching logic now no longer can format certain types as
the new type names generated by Clang's default printing policy no longer match
the type names that LLDB/the user specified.
I already introduced LLDB's own type printing policy and fixed the inline/anonymous
namespaces in da121fff1184267a405f81a87f7314df2d474e1c (just to get the
test suite passing again).
This patch is restoring the old type printing behaviour where always include the template
arguments in the internal type name (even if they match the default args). This should get
template type formatters/summaries working again in the rare situation where we do
know template default arguments within LLDB. This can only happen when either having
a template that was parsed in the expression parser or when we get type information from a C++ module.
The Clang change that removed defaulted template arguments from Clang's printing policy was

by craig.topper[RISCV] Only combine (or (GREVI x, shamt), x) -> GORCI if shamt is a power of 2.
GORCI performs an OR between each stage. So we need to ensure only
one stage is active before doing this combine.
Initial attempts at finding a test case for this failed due to
the order things get combined. It's most likely that we'll form
one stage of GREVI then combine to GORCI before the two stages of
GREVI are able to be formed and combined with each other to form
a multi stage GREVI.

by i[X86] Don't emit R_X86_64_[REX_]GOTPCRELX for a GOT load with an offset
clang may produce `movl x@GOTPCREL+4(%rip), %eax` when loading the high
32 bits of the address of a global variable in -fpic/-fpie mode.
If assembled by GNU as, the fixup emits R_X86_64_GOTPCRELX with an addend != -4.
The instruction loads from the GOT entry with an offset and thus it is incorrect
to relax the instruction.
This patch does not emit a relaxable relocation for a GOT load with an offset
because R_X86_64_[REX_]GOTPCRELX do not make sense for instructions which cannot
be relaxed. The result is good enough for LLD to work. GNU ld relaxes
mov+GOTPCREL as well, but it suppresses the relaxation if addend != -4.

This patch disables the relaxation, which is compatible with the implementation in GNU ld

Constraining to the range [0, Off_tMax] would result in a crash as that is
of a signed type with the value of 0xff..f (-1).
The crash would happen when we try to apply the arg constraints.
At line 583: assert(Min <= Max), as 0 <= -1 is not satisfied

c083fededfa63df6e1a560334bdb78797da9ee57
by hoy[CSSPGO] A Clang switch -fpseudo-probe-for-profiling for pseudo-probe instrumentation.
This change introduces a new clang switch `-fpseudo-probe-for-profiling` to enable AutoFDO with pseudo instrumentation. Please refer to https://reviews.llvm.org/D86193 for the whole story.
One implication from pseudo-probe instrumentation is that the profile is now sensitive to CFG changes. We perform the pseudo instrumentation very early in the pre-LTO pipeline, before any CFG transformation. This ensures that the CFG instrumented and annotated is stable and optimization-resilient.
The early instrumentation also allows the inliner to duplicate probes for inlined instances. When a probe along with the other instructions of a callee function are inlined into its caller function, the GUID of the callee function goes with the probe. This allows samples collected on inlined probes to be reported for the original callee function.

Under the relative vtables ABI, __dynamic_cast will not work since it assumes
the vtable pointer is 2 ptrdiff_ts away from the start of the vtable (8-byte
offset to top + 8-byte pointer to typeinfo) when it is actually 8 bytes away
(4-byte offset to top + 4-byte offset to typeinfo). This adjusts the logic under
__dynamic_cast and other areas vtable calculations are done to support this ABI
when it's used.

by nicholasCreating a named struct requires only a Context and a name, but looking up a struct by name requires a Module. The method on Module merely accesses the LLVMContextImpl and no data from the module itself, so this patch moves getTypeByName to a static method on StructType that takes a Context and a name.
There's a small number of users of this function, they are all updated.
This updates the C API adding a new method LLVMGetTypeByName2 that takes a context and a name.

This is a minor efficiency improvement, and should make further

by mtrofin[llvm][inliner] Reuse the inliner pass to implement 'always inliner'
Enable performing mandatory inlinings upfront, by reusing the same logic
as the full inliner, instead of the AlwaysInliner. This has the
following benefits:
- reduce code duplication - one inliner codebase
- open the opportunity to help the full inliner by performing additional
function passes after the mandatory inlinings, but before th full
inliner. Performing the mandatory inlinings first simplifies the problem
the full inliner needs to solve: less call sites, more contextualization, and,
depending on the additional function optimization passes run between the
2 inliners, higher accuracy of cost models / decision policies.
Note that this patch does not yet enable much in terms of post-always
inline function optimization.

by i[CodeGen] -fno-delete-null-pointer-checks: change dereferenceable to dereferenceable_or_null
After D17993, with -fno-delete-null-pointer-checks we add the dereferenceable attribute to the `this` pointer.
We have observed that one internal target which worked before fails even with -fno-delete-null-pointer-checks.
Switching to dereferenceable_or_null fixes the problem.
dereferenceable currently does not always respect NullPointerIsValid and may
imply nonnull and lead to aggressive optimization. The optimization may be
related to `CallBase::isReturnNonNull`, `Argument::hasNonNullAttr`, or
`Value::getPointerDereferenceableBytes`. See D66664 and D66618 for some discussions.

With the change to using shared memory, there were a few problems that need to be fixed.
- The previous filename that was used for SHM only used process id. Given that process is
usually based on 16bit number, this was causing some conflicts on machines. Thus we add
UID to the name to prevent this.
- It appears under some conditions (SIGTERM, etc) the shared memory files were not getting
cleaned up. Added a call to clean up the shm files under those conditions. For this user
needs to set envirable KMP_HANDLE_SIGNALS to true.
