[LLVMdev] Generate data16 assembly instruction for TLS with PIC
...e will not have
data16 instruction)
I search the llvm project and find some clues in this
file: lib/Target/X86/X86MCInstLower.cpp
static void LowerTlsAddr(...)
{
bool is64Bits = MI.getOpcode() == X86::TLS_addr64;
....
if (is64Bits) {
MCInst prefix;
prefix.setOpcode(X86::DATA16_PREFIX);
....
}
....
}
I think it is the logic to generate data16 instruction, but I wonder why
gcc report warning. Is it a LLVM's bug?
Thanks for your time in advance :D
