| Description | The attached module compiles much slower than it used to. I have bisected the regression to commit 911bc5ea0c6565b9ae48132b153182627b3ddbea "Convert more modules to use var_tables". The slow down occurs during the Fully expanding equivalence types step. % time ~/local/stow/mercury-srcdist-rotd-2022-04-29/bin/mmc -C parse_tables.m 0.63s user 0.03s system 99% cpu 0.662 total % time ~/local/stow/mercury-srcdist-rotd-2022-05-01/bin/mmc -C parse_tables.m 7.51s user 0.03s system 99% cpu 7.553 total |
