[LLVMdev] [PATCH] TLS support for Windows 32+64bit
Hi!
I added 2 more tests and also refined an assert statement. Applies
cleanly to r148473 now. Are there more comments on the code? Thank you!!

Hrm. Something is wonky here. Can you file a testcase with a .i file I can compile please?

Printing PC-relative offsets - how to get the instruction length?
...No);
ZZ
if (Op.isImm()) {
int64_t Imm = Op.getImm() + 2; <<<========================
O << "$";
if (Imm >= 0)
O << '+';
O << Imm;
} else {
assert(Op.isExpr() && "unknown pcrel immediate operand");
Op.getExpr()->print(O, &MAI);
}
}
Which works well enough except for the constant 2 that I've arrowed - it needs to be the length of the binary instruction in bytes. The MC6809 has a *LOT* of variability here, so a case statement would be a right pain to maintain.
An answer is tantalisingly clo...
