[Propeller] Read the CFG profile from the propeller directive. (#160422)

2025-09-24T18:52:11+00:00

The CFG allows us to do layout optimization in the compiler.
Furthermore, it allows further branch optimization.

[NFC] Split UniqueBBID definition to a separate file. (#148043)

[CodeGen] Use operator==(StringRef, StringRef) (NFC)

2024-05-17T04:53:54+00:00

The LHS and RHS are of SmallString and StringRef, respectively.  We
can safely use operator==(StringRef, SringRef) with one implicit
conversion from SmallString to StringRef.

[BasicBlockSections] Always keep the entry block in the beginning of the function. (#74696)

2024-01-16T22:15:33+00:00

BasicBlockSections must enforce placing the entry block at the beginning
of the function regardless of the basic block sections profile.
