Member Function Documentation
| virtual uint8_t* llvm::RTDyldMemoryManager::allocateCodeSection | ( | uintptr_t | Size, |
| unsigned | Alignment, | ||
| unsigned | SectionID | ||
| ) | [pure virtual] |
Allocate a memory block of (at least) the given size suitable for executable code. The SectionID is a unique identifier assigned by the JIT engine, and optionally recorded by the memory manager to access a loaded section.
Implemented in llvm::SectionMemoryManager.
| virtual uint8_t* llvm::RTDyldMemoryManager::allocateDataSection | ( | uintptr_t | Size, |
| unsigned | Alignment, | ||
| unsigned | SectionID, | ||
| bool | IsReadOnly | ||
| ) | [pure virtual] |
Allocate a memory block of (at least) the given size suitable for data. The SectionID is a unique identifier assigned by the JIT engine, and optionally recorded by the memory manager to access a loaded section.
Implemented in llvm::SectionMemoryManager.
| virtual bool llvm::RTDyldMemoryManager::finalizeMemory | ( | std::string * | ErrMsg = 0 | ) | [pure virtual] |
This method is called when object loading is complete and section page permissions can be applied. It is up to the memory manager implementation to decide whether or not to act on this method. The memory manager will typically allocate all sections as read-write and then apply specific permissions when this method is called. Code sections cannot be executed until this function has been called. In addition, any cache coherency operations needed to reliably use the memory are also performed.
Returns true if an error occurred, false otherwise.
Implemented in llvm::SectionMemoryManager.

| virtual void* llvm::RTDyldMemoryManager::getPointerToNamedFunction | ( | const std::string & | Name, |
| bool | AbortOnFailure = true |
||
| ) | [pure virtual] |
This method returns the address of the specified function. As such it is only useful for resolving library symbols, not code generated symbols.
If AbortOnFailure is false and no function with the given name is found, this function returns a null pointer. Otherwise, it prints a message to stderr and aborts.
Implemented in llvm::SectionMemoryManager.
Referenced by llvm::MCJIT::getPointerToNamedFunction(), and llvm::JIT::getPointerToNamedFunction().
| void RTDyldMemoryManager::registerEHFrames | ( | StringRef | SectionData | ) | [virtual] |
Register the EH frames with the runtime so that c++ exceptions work. The default implementation does nothing. Look at SectionMemoryManager for one that uses __register_frame.
Reimplemented in llvm::SectionMemoryManager.
