                           // instructions are issued while another

def GPR_Bypass : Bypass; // The bypass for general-purpose regs.
def FPR_Bypass : Bypass; // The bypass for floating-point regs.

// Notes:
// Instructions are held in the FRACC, LRACC and IRACC pipeline
// stages until their source operands become ready. Exceptions:
//  - Store instructions will hold in the AGEN stage
//  - The integer multiply-accumulate instruction will hold in
//    the IEXE1 stage
//
// For most I-pipe operations, the result is available at the end of
// the IEXE1 stage. Operations such as multiply and divide must
// continue to execute in IEXE2 and IWB. Divide resides in IWB for
// 33 cycles (multiply also calculates its result in IWB). For all
// J-pipe instructions, the result is available
// at the end of the JEXE1 stage. Loads have a 3-cycle latency
// (data is not available until after the LWB stage).
//
// The L1 cache hit latency is four cycles for floating point loads
// and three cycles for integer loads.
//
// The stwcx. instruction requires both the LRACC and the IRACC
// dispatch stages. It must be issued from DISS0.
//
// All lwarx/stwcx. instructions hold in LRACC if another
// uncommitted lwarx/stwcx. is in AGEN, CRD, or LWB.
//
// msync (a.k.a. sync) and mbar will hold in LWB until all load/store
// resources are empty. AGEN and CRD are held empty until the msync/mbar
// commits.
//
// Most floating-point instructions, computational and move,
// have a 5-cycle latency. Divide takes longer (30 cycles). Instructions that
// update the CR take 2 cycles. Stores take 3 cycles and, as mentioned above,
// loads take 4 cycles (for L1 hit).
