Hi,
I feel compiling gem5 is taking longer than what it should take for me. I
was wondering if anyone can measure and report for this scenario:
[a routine scenario happens when we debug]:
Compile gem5. Then touch one cc file, and then recompile with the command
below:
time scons build/X86/gem5.opt -j4
output:
[ CXX] X86/mem/cache/cache.cc -> .o
[VER TAGS] -> X86/sim/tags.cc
[ CXX] X86/sim/tags.cc -> .o
[ CXX] X86/base/date.cc -> .o
[ LINK] -> X86/gem5.opt
scons: done building targets.
