[PTLsim-devel] Big Issue queue not working properly rvn 225

Tue Jan 22 20:02:10 EST 2008

Hi,

It seems issue queue of size greater than 32 (48 or 64 in my case) is
not working properly in some really corner cases. Issue Queue
slotof(issuq_tag_t tag) method return -1 even though slot exists. On
delving further it seems uopids.search() wasn't returning the right
value. So I guess the problem lies in
FullyAssociativeTags16bit::search() method.

I use 32-bit PTLsim userspace rvn 225. I'm attaching a test_case.cpp.

regards,
abhishek
