IIUC this should have been a result of conditionalizing the prologue saves by the CCFSM state machine in ARM state given that the push instruction below doesn't have the conditional markers. In which case the routines to emit the asm for the VFP registers( vfp_output_fstmfd? ) should also be checked for this issue. cheers Ramana
