63
64def GPR_Bypass : Bypass; // The bypass for general-purpose regs.
65def FPR_Bypass : Bypass; // The bypass for floating-point regs.
66
67// Notes:
68// Instructions are held in the FRACC, LRACC and IRACC pipeline
69// stages until their source operands become ready. Exceptions:
70//  - Store instructions will hold in the AGEN stage
71//  - The integer multiply-accumulate instruction will hold in
72//    the IEXE1 stage
73//
74// For most I-pipe operations, the result is available at the end of
75// the IEXE1 stage. Operations such as multiply and divide must
76// continue to execute in IEXE2 and IWB. Divide resides in IWB for
77// 33 cycles (multiply also calculates its result in IWB). For all
78// J-pipe instructions, the result is available
79// at the end of the JEXE1 stage. Loads have a 3-cycle latency
80// (data is not available until after the LWB stage).
81//
82// The L1 cache hit latency is four cycles for floating point loads
83// and three cycles for integer loads.
84//
85// The stwcx. instruction requires both the LRACC and the IRACC
86// dispatch stages. It must be issued from DISS0.
87//
88// All lwarx/stwcx. instructions hold in LRACC if another
89// uncommitted lwarx/stwcx. is in AGEN, CRD, or LWB.
90//
91// msync (a.k.a. sync) and mbar will hold in LWB until all load/store
92// resources are empty. AGEN and CRD are held empty until the msync/mbar
93// commits.
94//
95// Most floating-point instructions, computational and move,
96// have a 5-cycle latency. Divide takes longer (30 cycles). Instructions that
97// update the CR take 2 cycles. Stores take 3 cycles and, as mentioned above,
98// loads take 4 cycles (for L1 hit).
