/*---------------------------------------------------------------------------
Scheduling guidelines for SPARC IIi:

I-Cache alignment rules (pg 326)
-- Align a branch target instruction so that it's entire group is within
   the same cache line (may be 1-4 instructions).
** Don't let a branch that is predicted taken be the last instruction
   on an I-cache line: delay slot will need an entire line to be fetched
-- Make a FP instruction or a branch be the 4th instruction in a group.
   For branches, there are tradeoffs in reordering to make this happen
   (see pg. 327).
** Don't put a branch in a group that crosses a 32-byte boundary!
   An artificial branch is inserted after every 32 bytes, and having
   another branch will force the group to be broken into 2 groups. 

iTLB rules:
-- Don't let a loop span two memory pages, if possible

Branch prediction performance:
-- Don't make the branch in a delay slot the target of a branch
-- Try not to have 2 predicted branches within a group of 4 instructions
   (because each such group has a single branch target field).
-- Try to align branches in slots 0, 2, 4 or 6 of a cache line (to avoid
   the wrong prediction bits being used in some cases).

D-Cache timing constraints:
-- Signed int loads of less than 64 bits have 3 cycle latency, not 2
-- All other loads that hit in D-Cache have 2 cycle latency
-- All loads are returned IN ORDER, so a D-Cache miss will delay a later hit
-- Mis-aligned loads or stores cause a trap.  In particular, replace
   mis-aligned FP double precision l/s with 2 single-precision l/s.
-- Simulations of integer codes show increase in avg. group size of
   33% when code (including esp. non-faulting loads) is moved across
   one branch, and 50% across 2 branches.

E-Cache timing constraints:
-- Scheduling for E-cache (D-Cache misses) is effective (due to load buffering)

Store buffer timing constraints:
-- Stores can be executed in same cycle as instruction producing the value
-- Stores are buffered and have lower priority for E-cache until
   highwater mark is reached in the store buffer (5 stores)

Pipeline constraints:
-- Shifts can only use IEU0.
-- CC setting instructions can only use IEU1.
-- Several other instructions must only use IEU1:
   EDGE(?), ARRAY(?), CALL, JMPL, BPr, PST, and FCMP.
-- Two instructions cannot store to the same register file in a single cycle
   (single write port per file).

Issue and grouping constraints:
-- FP and branch instructions must use slot 4.
-- Shift instructions cannot be grouped with other IEU0-specific instructions.
-- CC setting instructions cannot be grouped with other IEU1-specific instrs.
-- Several instructions must be issued in a single-instruction group:
	MOVcc or MOVr, MULs/x and DIVs/x, SAVE/RESTORE, many others
-- A CALL or JMPL breaks a group, ie, is not combined with subsequent instrs.
-- 
-- 

Branch delay slot scheduling rules:
-- A CTI couple (two back-to-back CTI instructions in the dynamic stream)
   has a 9-instruction penalty: the entire pipeline is flushed when the
   second instruction reaches stage 9 (W-Writeback).
-- Avoid putting multicycle instructions, and instructions that may cause
   load misses, in the delay slot of an annulling branch.
-- Avoid putting WR, SAVE..., RESTORE and RETURN instructions in the
   delay slot of an annulling branch.

// 2. Load-after-store is delayed by 7 extra cycles if load hits in D-Cache.
//    Also, several other store-load and load-store conflicts (pg 358)
// 3. MEMBAR, LD{X}FSR, LDD{A} and a bunch of other load stalls (pg 358)
// 4. There can be at most 8 outstanding buffered store instructions
//     (including some others like MEMBAR, LDSTUB, CAS{AX}, and FLUSH)
