Hi,
This change is causing gcc.dg/timevar[12].C to fail randomly, eg:
FAIL: g++.dg/ext/timevar1.C -std=gnu++2a (test for excess errors)
Excess errors:
phase opt and generate : 0.00 ( 0%) 0.00 ( 0%)
0.01 ( 50%) 8904 ( 0%)
callgraph construction : 0.00 ( 0%) 0.00 ( 0%)
0.01 ( 50%) 4096 ( 0%)
because SIZE_AMOUNT generates no suffix if the size is < 10k, and those tests
now use dg-prune-output "k" and dg-prune-output " 0 "
which is not enough.
Can you fix this?
Thanks
