◆ setCloneToNewContextOnEmit()

void llvm::orc::IRLayer::setCloneToNewContextOnEmit ( bool  CloneToNewContextOnEmit)
inline

Sets the CloneToNewContextOnEmit flag (false by default).

When set, IR modules added to this layer will be cloned on to a new context before emit is called. This can be used by clients who want to load all IR using one LLVMContext (to save memory via type and constant uniquing), but want to move Modules to fresh contexts before compiling them to enable concurrent compilation. Single threaded clients, or clients who load every module on a new context, need not set this.
