3*9880d681SAndroid Build Coastguard Worker; This tests for a bug where vertex fetch clauses right before an ENDIF
4*9880d681SAndroid Build Coastguard Worker; instruction where being emitted after the ENDIF.  We were using ALU_POP_AFTER
5*9880d681SAndroid Build Coastguard Worker; for the ALU clause before the vetex fetch instead of emitting a POP instruction
6*9880d681SAndroid Build Coastguard Worker; after the fetch clause.
