This patch builds on top of D119197 to canonicalize floating-point
SPLAT_VECTOR as RISCVISD::VFMV_V_F_VL as a pre-process ISel step.
This primarily benefits scalable-vector VP code, where our VP patterns
only match VFMV_V_F_VL to reduce the burden on our ISel patterns, but
where at the same time, scalable-vector code doesn't custom-legalize
SPLAT_VECTOR.

These patterns were omitted because clang only allows converting between
these types using intrinsics, but other front-ends or optimisation
passes may want to use them.

Reduce the amount of repetition in the declarations by leveraging more
TableGen constructs. This is in preparation for adding the OpenCL 3.0
atomics feature optionality.
The code was relying upon the implicit conversion of TypeSize to
uint64_t and assuming the type in question was always fixed. However,
I discovered an issue when running the canon-freeze pass with some
IR loops that contains scalable vector types. I've changed the code
to bail out if the size is unknown at compile time, since we cannot
compute whether the step is a multiple of the type size or not.
I added a test here:

Previously a lot of StoreRetval instructions with undef operand were

It resulted in a lot of unneeded st.param.* instructions in final

I think this was just being ignored before, but now it crashes because
we're checking if the projects that we're trying to enable are valid.
There is no test-suite project (it's a separate repo with separate

This change adds the selection for the no-return global_* and flat_*
instructions in tblgen. The motivation for this is to get the no-return atomic
isel working without relying on post-isel hooks so that GlobalISel can start
selecting them (once GlobalISelEmitter allows no return atomic patterns like
how DAGISel does).
Differential Revision: https://reviews.llvm.org/D119227
SelectionDAG relies on MachineInstr's HasPostISelHook for selecting the
no-return atomic ops. GlobalISel, at the moment, doesn't handle
HasPostISelHook.
This change adds the selection for no-return ds_* atomic ops in tblgen
so that it can work with both GlobalISel and SelectionDAG. I couldn't
add the predicates for GlobalISel in this change since there's a
restriction in GlobalISelEmitter that disallows selecting generic
atomics ops that return with instructions that doesn't return.
We can't remove the HasPostISelHook code that selects the no return
atomic ops in SelectionDAG yet since we still need to cover selections
in FLATInstructions.td, BUFInstructions.td.

We don't need precise control over the low-level behavior of these testcases so
C should be preferred for readability.
The new testcases test (1) the base dlopen case (running initializers and
deinitializers), and (2) the serial case of dlopen; dlclose; dlopen; dlclose,
where we expect the initializers and deinitializers to be run twice.
Power ISA 3.1 adds xsmaxcqp/xsmincqp for quad-precision type-c max/min selection,
and this opens the opportunity to improve instruction selection on: llvm.maxnum.f128,
llvm.minnum.f128, and select_cc ordered gt/lt and (don't care) gt/lt.

This change adds a pair of flags controlling whether llvm-symbolizer
attempts debuginfod lookups. Lookups are attempted if --debuginfod is
passed and disabled if --no-debuginfod is passed.
The default behavior is made more nuanced: debuginfod lookups are now
only attempted if an HTTP client is compiled in and at least one backing
debuginfod URL was configured via environment variable. Previously,
debuginfod lookups would always be attempted, even if there were no
chance that they could succeed.

A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the sixth batch of tests being updated (there are a significant
number of other tests left to be updated).
