Some trouble while building LLVM with -flto.
../x86_64-linux-gnu/bin/ld.gold: error: /tmp/cc60XH2F.ltrans0.ltrans.o:
requires dynamic R_X86_64_PC32 reloc against 'X86CompilationCallback2' which
may overflow at runtime; recompile with -fPIC
Code:
extern "C" {
void X86CompilationCallback(void);
asm(
".text\n"
".align 8\n"
".globl " ASMPREFIX "X86CompilationCallback\n"
TYPE_FUNCTION(X86CompilationCallback)
ASMPREFIX "X86CompilationCallback:\n"
...
"movq 8(%rbp), %rdx\n"
"call " ASMPREFIX "X86CompilationCallback2\n"
"addq $32, %rsp\n"
...
);
}
void __attribute__((used))
X86CompilationCallback2(intptr_t *StackPtr, intptr_t RetAddr) {
intptr_t *RetAddrLoc = &StackPtr[1];
...
}
}
