Looks like this is a bug that has since been fixed.
In case anyone stumbles upon this: the problem is that in
Event::getFlags(Flags _flags), the line
assert(flags.noneSet(~PublicRead));
should instead read
assert(_flags.noneSet(~PublicRead));
I.e. it should be checking whether the /argument /_flags are publicly
readable rather than the stored flags.
My own damn fault for not checking against the latest version in the
repository. D'oh.
Hi,
I'm messing with some timing details on the L2 level in the r6819
build, but I'm evidently doing something wrong as I'm getting this
assertion error when the event loop tries to exit:
m5.debug: build/ALPHA_SE/sim/eventq.hh:148: Flags<short int>
Event::getFlags(Flags<short int>) const: Assertion
`flags.noneSet(~PublicRead)' failed.
I dump()-ed the event in gdb:
Event Event_118 (simulation loop exit)
Flags: 0xf010
Created: 0
Not Scheduled
I also checked the cause of the event in gdb, and it's the "max insts
reached" exit event that I was expecting:
(gdb) p ((SimLoopExitEvent*) this)->cause
$3 = {static npos = 18446744073709551615, _M_dataplus =
{<std::allocator<char>> = {<__gnu_cxx::new_allocator<char>> = {<No
data fields>}, <No data fields>},
_M_p = 0x1eb7b78 "a thread reached the max instruction count"}}
However, it can't get executed because of some of its flags are not
set as expected. Here's a full stack trace:

Any ideas what can could cause this?
