All memory allocated by a call to JITLinkMemoryManager::allocate should be deallocated if a call is made to JITLinkMemoryManager::InFlightAllocation::abandon. The policies below apply to finalized allocations.

Enumerator

Standard

Standard memory should be allocated by the allocator and then deallocated when the deallocate method is called for the finalized allocation.

Finalize

Finalize memory should be allocated by the allocator, and then be overwritten and deallocated after all finalization functions have been run.

Error llvm::orc::addFunctionPointerRelocationsToCurrentSymbol	(	jitlink::Symbol &	Sym,

	)

Introduce relocations to Sym in its own definition if there are any pointers formed via PC-relative address that do not already have a relocation.

This is useful when introducing indirection via a stub function at link time without compiler support. If a function pointer is formed without a relocation, e.g. in the definition of foo

_foo:
  leaq -7(%rip), rax # form pointer to _foo without relocation
_bar:
  leaq (%rip), %rax  # uses X86_64_RELOC_SIGNED to '_foo'

the pointer to _foo computed by _foo and _bar may differ if we introduce a stub for _foo. If the pointer is used as a key, this may be observable to the program. This pass will attempt to introduce the missing "self-relocation" on the leaq instruction.

This is based on disassembly and should be considered "best effort". It may silently fail to add relocations.

◆ cloneFunctionDecl()

Function * llvm::orc::cloneFunctionDecl	(	Module &	Dst,

Clone a function declaration into a new module.

This function can be used as the first step towards creating a callback stub (see makeStub).

If the VMap argument is non-null, a mapping will be added between F and the new declaration, and between each of F's arguments and the new declaration's arguments. This map can then be passed in to moveFunction to move the function body if required. Note: When moving functions between modules with these utilities, all decls should be cloned (and added to a single VMap) before any bodies are moved. This will ensure that references between functions all refer to the versions in the new module.

Create a ExecutorProcessControl-based DebugObjectRegistrar that emits debug objects to the GDB JIT interface.

This will use the EPC's lookupSymbols method to find the registration/deregistration function addresses by name.

If RegistrationFunctionsDylib is non-None then it will be searched to find the registration functions. If it is None then the process dylib will be loaded to find the registration functions.

If SymbolLookupFlags::WeaklyReferencedSymbol is used then any missing symbols will have their corresponding address objects set to zero, and this function will never generate an error (the caller will need to check addresses before using them).

Configure the LLJIT instance to scrape modules for llvm.global_ctors and llvm.global_dtors variables and (if present) build initialization and deinitialization functions.

Platform specific initialization configurations should be preferred where available.

Definition at line 1193 of file LLJIT.cpp.

◆ setUpInactivePlatform()

Expected< JITDylibSP > llvm::orc::setUpInactivePlatform ( LLJIT & J )

Configure the LLJIT instance to disable platform support explicitly.

This is useful in two cases: for platforms that don't have such requirements and for platforms, that we have no explicit support yet and that don't work well with the generic IR platform.

The EPCIndirectionUtils' LazyCallThroughManager must have been previously created via EPCIndirectionUtils::createLazyCallThroughManager.

This function is experimental and likely subject to revision.

Useful for defining symbol aliases.: E.g., given a JITDylib JD containing symbols "foo" and "bar", we can define aliases "baz" (for "foo") and "qux" (for "bar") with:

SymbolStringPtr Baz = ...;
SymbolStringPtr Qux = ...;
if (auto Err = JD.define(symbolAliases({
