New Revision: 3782
Modified:
trunk/osprey/common/com/symtab_defs.h
trunk/osprey/ipa/common/ipc_symtab_merge.cxx
Log:
fixed bug 883. Revision 3760 add a new member "mUINT32 line" to structure ST,
it cause the function eq_const_st::operator() get wrong return value, then make
the symbol merge process in IPA not work. This patch fixed the problem in
fuction eq_const_st::operator(). I also add a common to make sure anyone who
add new member to structure ST also update function eq_const_st::operator()
