[MachineOutliner] Add profile guided outlining (#154437)

2025-09-09T17:06:46+00:00

[DebugInfo] Drop extra DIBuilder::finalizeSubprogram() calls (NFC) (#155618)

2025-08-27T15:58:29+00:00

After #139914, `DIBilder::finalize()` finalizes both declaration and
definition DISubprograms.
Therefore, there is no need to call `DIBuilder::finalizeSubprogram()`
right before `DIBilder::finalize()`.

[MachineOutliner] Remove LOHs from outlined candidates (#143617)

2025-06-30T21:29:06+00:00

Remove Linker Optimization Hints (LOHs) from outlining candidates
instead of simply preventing outlining if LOH labels are found in the
candidate. This will improve the effectiveness of the machine outliner
when LOHs are enabled (which is the default).

In
https://discourse.llvm.org/t/loh-conflicting-with-machineoutliner/83279/1
it was observed that the machine outliner is much more effective when
LOHs are disabled. Rather than completely disabling LOH, this PR aims to
keep LOH in most places and removing them from outlined functions where
it could be illegal. Note that we are conservatively removing all LOHs
from outlined functions for simplicity, but I believe we could retain
LOHs that are in the intersection of all candidates.

It should be ok to remove these LOHs since these blocks are being
outlined anyway, which will harm performance much more than the gain
from keeping the LOHs.

[LLVM][CodeGen] Add convenience accessors for MachineFunctionProperties (#140002)

2025-05-22T15:07:52+00:00

Add per-property has/set/reset functions to
MachineFunctionProperties.

[MachineOutliner] Add skipModule call for opt-bisect-limit. (#128836)

2025-02-26T16:28:45+00:00

[aarch64][win] Update Called Globals info when updating Call Site info (#122762)

2025-01-13T22:00:31+00:00

Fixes the "use after poison" issue introduced by #121516 (see
).

The root cause of this issue is that #121516 introduced "Called Global"
information for call instructions modeling how "Call Site" info is
stored in the machine function, HOWEVER it didn't copy the
copy/move/erase operations for call site information.

The fix is to rename and update the existing copy/move/erase functions
so they also take care of Called Global info.

[NFC] Remove some unnecessary semicolons

2024-12-16T08:48:57+00:00

All inside LLVM_DEBUG, some of which have been cleaned up by adding block
scopes to allow them to format more nicely.

[CodeGen] Remove unused includes (NFC) (#115996)

2024-11-13T07:15:06+00:00

Identified with misc-include-cleaner.

[llvm] Remove redundant calls to std::unique_ptr::get (NFC) (#113415)

2024-10-23T17:44:09+00:00

[LLVM] Use {} instead of std::nullopt to initialize empty ArrayRef (#109133)

2024-09-19T15:16:38+00:00

It is almost always simpler to use {} instead of std::nullopt to
initialize an empty ArrayRef. This patch changes all occurrences I could
find in LLVM itself. In future the ArrayRef(std::nullopt_t) constructor
could be deprecated or removed.
