Detailed Description
A basic block represents a single entry single exit section of code. Basic blocks contain a list of instructions which form the body of the block.
Basic blocks belong to functions. They have the type of label.
Basic blocks are themselves values. However, the C API models them as LLVMBasicBlockRef.

| LLVMBasicBlockRef LLVMAppendBasicBlock | ( | LLVMValueRef | Fn, |
| const char * | Name | ||
| ) |
Append a basic block to the end of a function using the global context.

| LLVMBasicBlockRef LLVMAppendBasicBlockInContext | ( | LLVMContextRef | C, |

| void LLVMDeleteBasicBlock | ( | LLVMBasicBlockRef | BB | ) |
Remove a basic block from a function and delete it.
This deletes the basic block from its containing function and deletes the basic block itself.

- llvm::BasicBlock::eraseFromParent()
Definition at line 1818 of file Core.cpp.
References llvm::unwrap().
Obtain the function to which a basic block belongs.

| void LLVMGetBasicBlocks | ( | LLVMValueRef | Fn, |
| LLVMBasicBlockRef * | BasicBlocks | ||
| ) |
Obtain all of the basic blocks in a function.
This operates on a function value. The BasicBlocks parameter is a pointer to a pre-allocated array of LLVMBasicBlockRef of at least LLVMCountBasicBlocks() in length. This array is populated with LLVMBasicBlockRef instances.
Definition at line 1754 of file Core.cpp.
References llvm::Function::begin(), llvm::Function::end(), I, and llvm::wrap().
Obtain the terminator instruction for a basic block.
If the basic block does not have a terminator (it is not well-formed if it doesn't), then NULL is returned.
The returned LLVMValueRef corresponds to a llvm::TerminatorInst.
- See also:
- llvm::BasicBlock::getTerminator()
Definition at line 1746 of file Core.cpp.
References llvm::unwrap(), and llvm::wrap().
Obtain the basic block that corresponds to the entry point of a function.
- See also:
- llvm::Function::getEntryBlock()
Definition at line 1760 of file Core.cpp.
References llvm::wrap().
Obtain the first basic block in a function.
The returned basic block can be used as an iterator. You will likely eventually call into LLVMGetNextBasicBlock() with it.

- llvm::Function::begin()
Definition at line 1764 of file Core.cpp.
References llvm::Function::begin(), llvm::Function::end(), I, and llvm::wrap().
Obtain the first instruction in a basic block.
The returned LLVMValueRef corresponds to a llvm::Instruction instance.

Obtain the last basic block in a function.

- llvm::Function::end()
Definition at line 1772 of file Core.cpp.
References llvm::Function::begin(), llvm::Function::end(), I, and llvm::wrap().
Obtain the last instruction in a basic block.

| LLVMBasicBlockRef LLVMInsertBasicBlockInContext | ( | LLVMContextRef | C, |
| LLVMBasicBlockRef | BB, | ||

Insert a basic block in a function before another basic block.
The function to add to is determined by the function of the passed basic block.
