◆ beginBasicBlockSection()

Process the beginning of a new basic-block-section within a function.

Always called immediately after beginFunction for the first basic-block. When basic-block-sections are enabled, called before the first block of each such section.

Reimplemented from llvm::AsmPrinterHandler.

◆ beginFunction()

Gather pre-function exception information.

Assumes being emitted immediately after the function entry point.

Implements llvm::AsmPrinterHandler.

◆ endBasicBlockSection()

Process the end of a basic-block-section within a function.

When basic-block-sections are enabled, called after the last block in each such section (including the last section in the function). When basic-block-sections are disabled, called at the end of a function, immediately prior to markFunctionEnd.
