- Add option to skip python dependency installation (useful for environments without internet connection). - Fix CheckArchSupport cmake script for RISC-V - Add "-fno-stack-protector" flag to avoid generating segfaults on the support library when tracing. - Remove usage of SIGSTKSZ in memory.h, since this variable is no longer available at compile time starting with glibc 2.34
- Refactor code for chop-perf-invok to improve readability, addition of future features. - Add option to take samples at a fixed time interval. - Fix chop-perf-invok test error reporting
- chop-weight is a tool for calculating the weight of a function invocation in terms of representativeness (after clustering). A python script exists already for doing so (cti_micro_weight), but this tool is way faster (written and optimized in C). - chop-perf-avg is a tool for averaging multiple chop-perf-invok measurements, calculating geometric mean and standard deviation.
Changes get_invocation_in_cluster to correctly index the cluster and invocation set arrays.
Code now checks for the return values of fread and getline
This needs to be generalized at some point in the feature.
Missing recursive detection in perf-invok

Missing the implementation of dummy functions in the tracer, which is still WIP and contains too many hard-coded variables.
