This patch is a small refactoring necessary for
'readability-isolate-declaration' and does not introduce functional changes.
It allows to use the utility functions without a full `ASTContext` and requires only the `SourceManager` and the `LangOpts`.

This patch adds an outer loop around the main BasicBlock simplifying code and adds a flag to the SimplifyCFGOpt class that can be set by to request another iteration. I don't think we can iterate based just on the change flag alone since some of the simplifications delete a basic block entirely leaving nothing to iterate on.

[AST] Revert mangling changes from r339428

As discussed in https://reviews.llvm.org/D50144, we want Obj-C classes
to have the same mangling as C++ structs, to support headers like the
following:

```
@class I;
struct I;

void f(I *);
```

since the header can be used from both C++ and Obj-C++ TUs, and we want
a consistent mangling across the two to prevent link errors. Itanium
mangles both the same way, and so should the MS ABI.

The main concern with having the same mangling for C++ structs and Obj-C
classes was that we want to treat them differently for the purposes of
exception handling, e.g. we don't want a C++ catch statement for a
struct to be able to catch an Obj-C class with the same name as the
struct. We can accomplish this by mangling Obj-C class names differently
in their RTTI, which I'll do in a follow-up patch.

was previously just dropped from the query rather than being treated as
empty. Now that we have the FALSE iterator, we can use it instead.

The query tree logic previously had a bunch of special cases to detect whether
subtrees are empty. Now we just naively build the whole tree, and rely
on the query optimizations to drop the trivial parts.

Finally, there was a bug in trigram generation: the empty query would
generate a single trigram "$$$" instead of no trigrams.
This had no effect (there was no posting list, so the other bug
cancelled it out). But we now have to fix this bug too.

Before this fix, the bugprone-use-after-move check could incorrectly
conclude that a use and move in a function template were not sequenced.

6 years ago[RISCV] Bugfix for floats passed on the stack with the ILP32 ABI on RV32F
Alex Bradbury [Thu, 4 Oct 2018 07:28:49 +0000 (07:28 +0000)]
[RISCV] Bugfix for floats passed on the stack with the ILP32 ABI on RV32F

f32 values passed on the stack would previously cause an assertion in
unpackFromMemLoc.. This would only trigger in the presence of the F extension
making f32 a legal type. Otherwise the f32 would be legalized.

This patch fixes that by keeping LocVT=f32 when a float is passed on the
stack. It also adds test coverage for this case, and tests that also
demonstrate lw/sw/flw/fsw will be selected when most profitable. i.e. there is
no unnecessary i32<->f32 conversion in registers.
