I have a large project that has a somewhat quirky coding style (lots of
questionable macros) and I'm trying to get cscope to give me a list of
functions that call another function, X.
My understanding is that that is what the -L3 option is for. However,
when I run -L3 on any function of interest, cscope reports no results.
-L0, however, does list everything.
So for now, my project parses the output of -L0 and attempts to ignore
references that do not apply. However, I don't understand why -L3 isn't
working. cscope is obviously able to parse the C code correctly.
Here's an example:
$ cscope -d -L0 constructPwrChannel
kernel/inc/pmgr/pwrchannel.h <global> 149 BoardObjConstruct constructPwrChannel;
kernel/pmgr/nv/pwrchannel.c <global> 136 constructPwrChannel
kernel/pmgr/nv/pwrchannel.c <global> 774 return constructPwrChannel(pGpu,
ppBoardObj, size, pArgs);
kernel/pmgr/nv/pwrchannel_pstate_est_lut.c <global> 57 status =
constructPwrChannel(pGpu, ppBoardObj, size, pArgs);
kernel/pmgr/nv/pwrchannel_sensor.c <global> 56 status =
constructPwrChannel(pGpu, ppBoardObj, size, pArgs);
kernel/pmgr/nv/pwrchannel_sum.c <global> 60 status = constructPwrChannel(pGpu,
ppBoardObj, size, pArgs);
In this case, -L3 should return the last four lines, but I get nothing
instead:
$ cscope -vd -L3 constructPwrChannel
