Jim Grosbach f8c1c8465f MCJIT lazy relocation resolution and symbol address re-assignment. ... Add handling for tracking the relocations on symbols and resolving them. Keep track of the relocations even after they are resolved so that if the RuntimeDyld client moves the object, it can update the address and any relocations to that object will be updated. For our trival object file load/run test harness (llvm-rtdyld), this enables relocations between functions located in the same object module. It should be trivially extendable to load multiple objects with mutual references. As a simple example, the following now works (running on x86_64 Darwin 10.6): $ cat t.c int bar() { return 65; } int main() { return bar(); } $ clang t.c -fno-asynchronous-unwind-tables -o t.o -c $ otool -vt t.o t.o: (__TEXT,__text) section _bar: 0000000000000000 pushq %rbp 0000000000000001 movq %rsp,%rbp 0000000000000004 movl $0x00000041,%eax 0000000000000009 popq %rbp 000000000000000a ret 000000000000000b nopl 0x00(%rax,%rax) _main: 0000000000000010 pushq %rbp 0000000000000011 movq %rsp,%rbp 0000000000000014 subq $0x10,%rsp 0000000000000018 movl $0x00000000,0xfc(%rbp) 000000000000001f callq 0x00000024 0000000000000024 addq $0x10,%rsp 0000000000000028 popq %rbp 0000000000000029 ret $ llvm-rtdyld t.o -debug-only=dyld ; echo $?
