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)

Defines the type of a yield callback.

◆ anonymous enum

anonymous enum : unsigned

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().

Remove the GC for a function.

References llvm::LLVMContextImpl::GCNames, and pImpl.

◆ 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.

◆ emitError() [1/2]

void LLVMContext::emitError ( const Instruction *  I,
const Twine &  ErrorStr 
)

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 ".".

◆ getDefaultTargetCPU()

StringRef LLVMContext::getDefaultTargetCPU ( )

Get or set the current "default" target CPU (target-cpu function attribute).

The intent is that compiler frontends will set this to a value that reflects the attribute that a function would get "by default" without any specific function attributes, and compiler passes will attach the attribute to newly created functions that are not associated with a particular function, such as global initializers. Function::createWithDefaultAttr() will create functions with this attribute. This function should only be called by passes that run at compile time and not by the backend or LTO passes.

Three possible return values: 0 - threshold is disabled. Everything will be printed out. positive int - threshold is set.

Note that in case of missing profile summary, threshold will be kept at "MAX", effectively suppresses all remarks output.

◆ 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.

◆ shouldDiscardValueNames()

bool LLVMContext::shouldDiscardValueNames ( ) const

Return true if the Context runtime configuration is set to discard all value names.

When true, only GlobalValue names will be available in the IR.

◆ yield()

void LLVMContext::yield ( )

Calls the yield callback (if applicable).

This transfers control of the current thread back to the client, which may suspend the current thread. Only call this method when LLVM doesn't hold any global mutex or cannot block the execution in another LLVM context.
