40bdcda32d It's a bit sloppy, but the global history predictor is working correctly now. 
There were two major bugs with the predictor.
First the update mechanism was completely wrong.  The PHT is updated with the GHR that was used to lookup the prediction.  PHT[GHR] = Sat2(PHT[GHR], branch outcome).
Second the GHR needs to be updated speculatively as the branch is predicted.  This is important so that back to back branches' GHRs are not the same.  The must be different to avoid aliasing.  Speculation of the GHR update allows them to be different.  On mis prediction the GHR must be reverted.
This implementation is a bit sloppy with names and now the GHR recovery is performed.  Updates to follow.

7c8d2e9b78 Partially working icache. 
The current issue is a StallF is required to halt the icache from getting an updated PCF. However
if the dmemory is the reason for a stall it is possible for the icache stall to hold the d memory request continuously causing d memory to repeatedly read from memory.  This keeps StallF high and
the icache FSM is never allowed to complete.

75b97f1422 Created special test for driving the instruction spill error. 
The extact problem occurs when a 4 byte instruction startles two cache blocks (or without a cache two ahbi words) and the code jumps to a cache block other than the next cache block. Consider the following sample of code.

0000000000000080 <test_spill>:
  80:	42a9                	li	t0,10
  82:	0001                	nop
  84:	0001                	nop
  86:	0001                	nop
  88:	02bd                	addi	t0,t0,15
  8a:	00628e33          	add	t3,t0,t1
  8e:	01ce8963          	beq	t4,t3,a0 <match>

0000000000000092 <failure>:
  92:	557d                	li	a0,-1
  94:	8082                	ret
  96:	00000013          	nop
  9a:	00000013          	nop
  9e:	0001                	nop

00000000000000a0 <match>:
  a0:	1ffd                	addi	t6,t6,-1
  a2:	fc0f9fe3          	bnez	t6,80 <test_spill>
  a6:	4501                	li	a0,0
  a8:	8082                	ret

Instructions 0x88, 0x8a and 0x8e are read incorrectly.  However once the branch predictor begins to correctly predict the beq at 0x8e the instrution at 0xa0 is loaded incorrectly as the 2 upper bytes of 0x8e and the two bytes of 0x92.  This amalgamation causes c.addi at 0xa0 to do something else and the loop never terminates.

The button of wavefile wave.do shows the exact problem in the 'icache'.

f1107c5d7b Corrected a number of bugs in the branch predictor. 
Added performance counters to individually track
branches; jumps, jump register, jal, and jalr; return.
jump and jump register are special cases of jal and jalr.
Similarlly return is a special case of jalr.
Also added counters to track if the branch direction was wrong,
btb target wrong, or the ras target was wrong.
Finally added one more counter to track if the BP incorrectly predicts
a non-cfi instruction.

1e83810450 Merge of main with the new icache and the branch predictor. I believe there is a bug in the icache with unaligned memory access. The second part of the access is incorrectly relying on the PCF being the address of the next two bytes of the instruction. However this is not always the case as the branch predictor can get the wrong target address. The icache needs to generate the +2 address internally. 2021-03-30 23:18:20 -05:00
