Detailed Description

This is an important class for using LLVM in a threaded context.

It (opaquely) owns and manages the core "global" data of LLVM's core infrastructure, including the type and constant uniquing tables. LLVMContext itself provides no locking guarantees, so you should be careful to have one context per thread.

◆ YieldCallbackTy

using llvm::LLVMContext::YieldCallbackTy = void (*)(LLVMContext *Context, void *OpaqueHandle)

Known operand bundle tag IDs, which always have the same value.

All operand bundle tags that LLVM has special knowledge of are listed here. Additionally, this scheme allows LLVM to efficiently check for specific operand bundle tags without comparing strings. Keep this in sync with LLVMContext::LLVMContext().

◆ diagnose()

void LLVMContext::diagnose ( const DiagnosticInfo &  DI)

Report a message to the currently installed diagnostic handler.

This function returns, in particular in the case of error reporting (DI.Severity == DS_Error), so the caller should leave the compilation process in a self-consistent state, even though the generated code need not be correct.

The diagnostic message will be implicitly prefixed with a severity keyword according to DI.getSeverity(), i.e., "error: " for DS_Error, "warning: " for DS_Warning, and "note: " for DS_Note.

void LLVMContext::emitError ( uint64_t  LocCookie,

emitError - Emit an error message to the currently installed error handler with optional location information.

This function returns, so code should be prepared to drop the erroneous construct on the floor and "not crash". The generated code need not be correct. The error message will be implicitly prefixed with "error: " and should not end with a ".".

◆ setYieldCallback()

void LLVMContext::setYieldCallback ( YieldCallbackTy  Callback,
void *  OpaqueHandle 
)

Registers a yield callback with the given context.

The yield callback function may be called by LLVM to transfer control back to the client that invoked the LLVM compilation. This can be used to yield control of the thread, or perform periodic work needed by the client. There is no guaranteed frequency at which callbacks must occur; in fact, the client is not guaranteed to ever receive this callback. It is at the sole discretion of LLVM to do so and only if it can guarantee that suspending the thread won't block any forward progress in other LLVM contexts in the same process.

At a suspend point, the state of the current LLVM context is intentionally undefined. No assumptions about it can or should be made. Only LLVM context API calls that explicitly state that they can be used during a yield callback are allowed to be used. Any other API calls into the context are not supported until the yield callback function returns control to LLVM. Other LLVM contexts are unaffected by this restriction.
