The scalar instruction of this is `llvm.trunc`. However the naming of

`vp.roundtozero` that will look similar to `vp.roundeven`.

[LLDB] Fix crash when printing a struct with a static signed char member
As with static bool for whatever reason printing them on their own
worked fine but wasn't handled when you printed the whole type.
I don't see a good way to test this from clang's side so our existing

We can now print all of the struct "A", so there's no need for a separate
one for static bool testing. I've not checked the output, just that it
succeeds. This saves us having to handle different min/max between systems.

Relative to the previous attempt, this adjusts simplification to

foldOpIntoPhi() currently only folds operations into the phi if all

This patch makes foldOpIntoPhi() generally simplification based and

[LLDB] Fix printing a static bool struct member when using "image lookup -t"
Fixes #58135
Somehow lldb was able to print the member on its own but when we try
to print the whole type found by "image lookup -t" lldb would crash.
This is because we'd encoded the initial value of the member as an integer.
Which isn't the end of the world because bool is integral for C++.
However, clang has a special AST node to handle literal bool and it
expected us to use that instead.
This adds a new codepath to handle static bool which uses cxxBoolLiteralExpr
and we get the member printed as you'd expect.
For testing I added a struct with just the bool because trying to print
all of "A" crashes as well. Presumably because one of the other member's
types isn't handled properly either.
So for now I just added the bool case, we can merge it with A later.

Fix the use_lld() to use llvm_shlib_dir similarly to how use_clang()

i.e. the directory with system-installed LLVM libraries before
the build directory of standalone build. As a result, the shared
libraries from an earlier version of clang end up being used instead of
the newly built version when running the test suite prior to installing.
To reproduce the problem, build and install LLVM with dylibs first,
e.g.:
cmake ../llvm -G Ninja -DCMAKE_BUILD_TYPE=MinSizeRel \
-DCMAKE_INSTALL_PREFIX="${HOME}"/llvm-test \
-DLLVM_BUILD_LLVM_DYLIB=ON -DLLVM_LINK_LLVM_DYLIB=ON \
-DLLVM_INSTALL_UTILS=ON
ninja install
Then build clang against that installation and run tests:
export LD_LIBRARY_PATH=~/llvm-test/lib
export PATh=~/llvm-test/bin:"${PATH}"
cmake ../clang -G Ninja -DCMAKE_BUILD_TYPE=MinSizeRel \
-DCMAKE_INSTALL_PREFIX="${HOME}"/llvm-test \
-DCLANG_LINK_CLANG_DYLIB=ON -DLLVM_BUILD_TESTS=ON \
-DLLVM_EXTERNAL_LIT="${PWD}"/bin/llvm-lit
ninja check-clang
The tests will be run with LD_LIBRARY_PATH of:
/home/${USER}/llvm-test/lib:/home/${USER}/llvm-project/build-clang/lib
As a result, installed libclang-cpp will take precedence over the one
from build dir. With the patch, the correct path is used, i.e.:

[flang] Improve syntax error messages by fixing withMessage() parser combinator
The parser combinator withMessage("error message"_err_en_US, PARSER) is meant
to run the parser PARSER and, if it fails, override its error messages if
it failed silently or it was unable to recognize any tokens at all. This
gives the parser a way to avoid emitting some confusing or missing error
messages. Unfortunately, the implementation could sometimes lose track of
whether any tokens had been recognized, leading to problems with outer usage
of withMessage() and also -- more seriously -- with ParseState::CombineFailedParses().
That's a utility that determines which error messages to retain when two
or more parsers have been attempted at the same starting point and none
of them succceed. Its policy is to retain the state from the parser that
consumed the most input text before failing, so long as it had recognized at
least one token.
So anyway, fix up withMessage(), adjust the tests, and add a test of the
original motivating confusing error situation, in which a syntax error in
a COMMON statement was being diagnosed as a problem with a statement function
definition because withMessage() had lost the fact that the parse of the
COMMON statement had recognized some tokens, and the last attempted parse
later was a failed attempt to parse a statement function.

Thread safety analysis: Support copy-elided production of scoped capabilities through arbitrary calls
When support for copy elision was initially added in
e97654b2f2807, it
was taking attributes from a constructor call, although that constructor
call is actually not involved. It seems more natural to use attributes
on the function returning the scoped capability, which is where it's
actually coming from. This would also support a number of interesting
use cases, like producing different scope kinds without the need for tag
types, or producing scopes from a private mutex.
Changing the behavior was surprisingly difficult: we were not handling
CXXConstructorExpr calls like regular calls but instead handled them
through the DeclStmt they're contained in. This was based on the
assumption that constructors are basically only called in variable
declarations (not true because of temporaries), and that variable
declarations necessitate constructors (not true with C++17 anymore).
Untangling this required separating construction from assigning a
variable name. When a call produces an object, we use a placeholder
til::LiteralPtr for `this`, and we collect the call expression and
placeholder in a map. Later when going through a DeclStmt, we look up
the call expression and set the placeholder to the new VarDecl.
The change has a couple of nice side effects:
* We don't miss constructor calls not contained in DeclStmts anymore,
allowing patterns like
MutexLock{&mu}, requiresMutex();
The scoped lock temporary will be destructed at the end of the full
statement, so it protects the following call without the need for a
scope, but with the ability to unlock in case of an exception.
* We support lifetime extension of temporaries. While unusual, one can
now write
const MutexLock &scope = MutexLock(&mu);
and have it behave as expected.
* Destructors used to be handled in a weird way: since there is no
expression in the AST for implicit destructor calls, we instead
provided a made-up DeclRefExpr to the variable being destructed, and
passed that instead of a CallExpr. Then later in translateAttrExpr
there was special code that knew that destructor expressions worked a
bit different.
* We were producing dummy DeclRefExprs in a number of places, this has
been eliminated. We now use til::SExprs instead.
Technically this could break existing code, but the current handling
seems unexpected enough to justify this change.
