CodeSizer: Why is that binary so big?

SMRTR summary

CodeSizer is a static code size profiling tool built for embedded firmware developers who need to understand why their binaries are bloated. It uses objdump and addr2line to trace inline call stacks at every instruction address, correctly attributing code size through LTO and inlining. The result is an interactive HTML report with a collapsible tree view showing exactly where binary size comes from.
