Yes, thanks. The intended word logic is: under -m32 -fPIC, when we want
to extract the symbol TN from the expanded code, if there are sequences of
Tmp_TN :- ld32 %ebx (sym:base)
TN :- lea32 Tmp_TN (base_ofst)
we build symbol TN of (sym:base + base_ofst) , set the RELOC to
RELOC_IA32_GOTOFF
if it is a constant, we extrance directly from ldc32, otherwise, we can
always get the symbol TN from the kid1 of lda_op.
