Member Function Documentation
| char * X86JITInfo::allocateThreadLocalMemory | ( | size_t | size | ) | [virtual] |
allocateThreadLocalMemory - Each target has its own way of handling thread local variables. This method returns a value only meaningful to the target.
Reimplemented from llvm::TargetJITInfo.
Definition at line 574 of file X86JITInfo.cpp.
References llvm_unreachable.
| void * X86JITInfo::emitFunctionStub | ( | const Function * | F, |
| void * | Target, | ||
| JITCodeEmitter & | JCE | ||
| ) | [virtual] |
emitFunctionStub - Use the specified JITCodeEmitter object to emit a small native function that simply calls the function at the specified address.
Reimplemented from llvm::TargetJITInfo.

| void * X86JITInfo::emitGlobalValueIndirectSym | ( | const GlobalValue * | GV, |
| void * | ptr, | ||
| JITCodeEmitter & | JCE | ||
| ) | [virtual] |
emitGlobalValueIndirectSym - Use the specified JITCodeEmitter object to emit an indirect symbol which contains the address of the specified ptr.
Reimplemented from llvm::TargetJITInfo.

| TargetJITInfo::LazyResolverFn X86JITInfo::getLazyResolverFunction | ( | JITCompilerFn | F | ) | [virtual] |
getLazyResolverFunction - Expose the lazy resolver to the JIT.

Definition at line 77 of file X86JITInfo.h.
| uintptr_t X86JITInfo::getPICJumpTableEntry | ( | uintptr_t | BB, |
| uintptr_t | Entry | ||
| ) | [virtual] |
getPICJumpTableEntry - Returns the value of the jumptable entry for the specific basic block.
Reimplemented from llvm::TargetJITInfo.
Definition at line 521 of file X86JITInfo.cpp.
| TargetJITInfo::StubLayout X86JITInfo::getStubLayout | ( | ) | [virtual] |
Returns the maximum size and alignment for a call stub on this target.

| void X86JITInfo::relocate | ( | void * | Function, |
| MachineRelocation * | MR, | ||
| unsigned | NumRelocs, | ||
| unsigned char * | GOTBase | ||
| ) | [virtual] |
relocate - Before the JIT can run a block of code that has been emitted, it must rewrite the code to contain the actual addresses of any referenced global symbols.
Reimplemented from llvm::TargetJITInfo.

| void X86JITInfo::replaceMachineCodeForFunction | ( | void * | Old, |
| void * | New | ||
| ) | [virtual] |
replaceMachineCodeForFunction - Make it so that calling the function whose machine code is at OLD turns into a call to NEW, perhaps by overwriting OLD with a branch to NEW. This is used for self-modifying code.
Implements llvm::TargetJITInfo.
