...essibleMemOnly flag. The intrinsic comes with most of the semantics of a PGO counter but is much less optimization-intrusive. The pseudo probe intrinsic calls are on the IR throughout the optimization and code generation pipeline and are materialized as a piece of binary data stored in a separate .pseudo_probe data section. The section is then used to map binary samples back to blocks of CFG during profile generation. There are also no real machine instructions generated for a pseudo probe and the.pseudo_probe section won’t be loaded into memory at runtime, therefore they should incur very little runtim...

The pseudo probe intrinsic calls are on the IR throughout the optimization and code generation pipeline and are materialized as a piece of binary data stored in a separate .pseudo_probe data section. How are these information maintained? Blocks can be eliminated or cloned in many optimization passes: jump threading, taildup, unrolling, peeling etc. For instance, how to handle the block that is merged into another? Does it lose samples because of this? [wenlei] They are just ma...
