llvm::splitBB

Split a basic block at an IRBuilder insertion point.

Synopsis

Declared in <llvm/Frontend/OpenMP/OMPIRBuilder.h>

BasicBlock*
splitBB(
    IRBuilderBase& Builder,
    bool CreateBranch,
    llvm::Twine Name = {});

Description

Split a BasicBlock at Builder's insertion point, even if the block is degenerate (missing the terminator). Its new insert location will stick to after the instruction before the insertion point (instead of moving with the instruction the InsertPoint stores internally).

Return Value

The new successor basic block.

Parameters

Name

Description

Builder

IRBuilder whose insertion point marks the split location.

CreateBranch

When true, insert a branch to the new successor block.

Name

Optional name for the new successor block.
