VEELFMCAsmInfo::VEELFMCAsmInfo(const Triple &TheTriple) {
   Data32bitsDirective = "\t.4byte\t";
   Data64bitsDirective = "\t.8byte\t";
 
   // Uses '.section' before '.bss' directive.  VE requires this although
   // assembler manual says sinple '.bss' is supported.
   UsesELFSectionDirectiveForBSS = true;
 
   SupportsDebugInformation = true;
-  UseIntegratedAssembler = false;
