◆ setRegMayBeFolded()

void llvm::InlineAsm::Flag::setRegMayBeFolded ( bool B )

inline

Set a bit to denote that while this operand is some kind of register (use, def, ...), a memory flag did appear in the original constraint list.

This is set by the instruction selection framework, and consumed by the register allocator. While the register allocator is generally responsible for spilling registers, we need to be able to distinguish between registers that the register allocator has permission to fold ("rm") vs ones it does not ("r"). This is because the inline asm may use instructions which don't support memory addressing modes for that operand.
