[RISCV] Fix regression due to interaction of MachineOutliner and MachineCopyPropagation

D144535 enabled machine copy propagation for RISC-V and added it to the
pass pipeline in addPreEmitPass2 (after the MachineOutliner).
Unfortunately, the MachineCopyPropagation pass is unable to correctly
analyse outlined functions, and will delete copy instructions where a
register is set that is intended to be live-out.
RISCVInstrInfo::buildOutlinedFrame will directly insert a JALR, while a
similar function going through the normal codegen path would have a
PseudoRet with operands indicating registers that are live-out.

This patch does the simplest fix, which is to run MachineCopyPropagation
before the MachineOutliner.

16 months ago[NFC][libc++][format] Improves diagnostics.
Mark de Wever [Fri, 17 Feb 2023 20:27:08 +0000 (21:27 +0100)]
[NFC][libc++][format] Improves diagnostics.

While implementing the tests for LWG3720 I noticed the std::format
errors for non-formattable types are not user friendly (and thus hard to
write a .verify test too).

The issue stems from using a deleted function for invalid types. By
using a function that returns an invalid value the diagnostics become a
lot better. Before this change the existing "invalid value"
static_assert could never trigger. Now it can be triggered by user
code, therefore a diagnostic message has been added.

[libc] Set the stub filename to the target name instead of the source

The GPU target requires some weird special case handling to create fat
binaries. CMake offers no way to set the name of an object library. The
only way to do this is to create a file with the desired name and use
that. Currently we name it after the source filename. However, this
breaks if there is more than a single source. This patch changes the
logic to instead look up the object target name and use that. E.g.
`src.__support.OSUtil.osutil` will be `osutil.cpp`.

Fix false positive with unreachable C++ catch handlers

This addresses an issue found by WG21 and tracked by CWG2699 (which is
not yet publicly published). The basic problem is that Clang issues a
diagnostic about not being able to reach a handler, but that handler
*is* reached at runtime. Clang's diagnostic behavior was matching the
standard wording, and our runtime behavior was matching the standard's
intent.

This fixes the diagnostic so that it matches the runtime behavior more
closely, and reduces the number of false positives. This is the
direction of choice taken by Core for CWG2699 and it seems unlikely
that WG21 will change direction here.

Reapply [LowerTypeTests] Avoid creation of select constant expression

Reapply with a fix for phi handling: For phis, we need to insert
into the incoming block, not above the phi. This is especially
tricky if there are multiple incoming values from the same
predecessor, because these must all use the same value.

-----

LowerTypeTests replaces weak declarations with an icmp+select
constant expressions. As this is not a relocatable expression,
it additionally promotes initializers using it to global ctors.

As part of https://discourse.llvm.org/t/rfc-remove-most-constant-expressions/63179,
I would like to remove the select constant expression, of which LTT
is now the last user. This is a bit tricky, because we now need to
replace a constant with an instruction, which might require
converting intermediate constant expression users to instructions as
well.

We do this using the convertUsersOfConstantsToInstructions() helper.
However, it needs to be slightly extended to also support expansion
of ConstantAggregates. These are important in this context, because
the promotion of initializers to global ctors will produce stores
of such aggregates.

[IndVars] Option verify-indvars is broken (and always has been), delete it

This option is switched off by default, and it seems that it has never worked correctly.
What it basically does is: it remembers current BECount SCEV, and after all transforms
tries to validate some facts for it. However, between these two points this SCEV may
become invalid (e.g. because some SCEVUnknown it references may be deleted as dead
code). So basically it may work with broken pointers.

Besides, its implementation does strange things (e.g. forgetLoop) which are invasive and
may affect behavior in other parts of the system (specifically verification), concealing some
other problems. Another issue is that it may use SCEVCouldNotCompute object without
checking this.

The option is not used in any unit tests, and if switched on by default, the following tests
fail:
```

None of these looks like real problems found by verification, these are
bugs in the verifying code itself (such as use of deleted SCEVs and
SCEVCouldNotCompute's).

I think it all gives enough justification for its removal.
