AMDGPU/GlobalISel: Switch to extended LLTs
With minimal changes. Most notably because of changes to jumptable in isel
GIM_SwitchType requires explicit integer/float types and does not match scalar.
In most places change is in lowering to use LLT::integer or LLT::float.
Other changes:
- replaceRegWith can also change type on Dst register, this can cause CSE data
corruption (fix is to notify observer)
- mixed i32/f32 in G_MERGE_VALUES/G_UNMERGE_VALUES, common in legalizing
ray tracing and image intrinsics
- need extra bitcast between i32/f32 in some place
[HotColdSplit] Unconditionally mark new functions as cold (#200947)
Previously, HotColdSplit would only mark functions as cold if there was
a profile summary available in the module metadata. This was causing
profcheck failures and is inconsistent with how we handle profile
metadata in other parts of the compiler.
This behavior has been around since
c36c10ddfb3dc07129b9f3973029d17940f6a45f when the profile annotation was
first introduced.
[lldb][windows] explicitly load python3.dll in PythonRuntimeLoader (#201399)
When building with the Python stable API, `liblldb.dll`'s delay-load
crashes because it needs `python3.dll` and it can't find it
Loading `python310.dll` via `LoadLibrary` with a full path doesn't add
Python's directory to the DLL search path for subsequent loads.
This patch also explicitly loads `python3.dll` from the same directory
in `PythonRuntimeLoader` to fix the issue.
This is needed for https://github.com/llvm/llvm-project/pull/200533.
[Hexagon] Add cmake caches for cross-toolchain distribution build (#201207)
Adds and extends the
clang/cmake/caches/hexagon-unknown-linux-musl-clang* files to drive a
full install-distribution build: host tools, per-target builtins (Linux
and baremetal), and runtimes for hexagon-unknown-linux-musl.
