Also some times it used int variables and some times uint16_t, leading to wrong behaviour - Confidence counter (it was 2 bits ins some parts of the code and 3 bits in some other parts. It should be 2 bits) - Iteration counters (they were 16 bits and they should be 14 bits) All the new sizes are now configurable Change-Id: I8884c7454c1e510b65160eb4d5749d3259d34096 Signed-off-by: Pau Cabre <pau.cabre@metempsy.com> Reviewed-on: https://gem5-review.googlesource.com/c/14216 Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Maintainer: Jason Lowe-Power <jason@lowepower.com> |
