Spectral norm allocations increased 17% between 7.6 and 7.8
It appears that
spectral-norm regressed rather severely from 7.6 to 7.8 in total allocations. Meanwhile the binary size also increased by 7% or so. However, it also appears that runtime was unaffected by this change.
The rule firings are very similar between 7.6 and 7.8. Three rules fire in 7.8 that do not fire in 7.6,
1 Class op formatArg 1 Class op parseFormat 1 tagToEnum#
The difference in allocation persists even if one reverts the
Text.Printf rewrite that gives rise to the
parseFormat rules, so these can be safely ignored.
