Line Execution Checker

Purpose

Fast tool to check if specific source lines were executed during test runs.

Tool: line-checker

Build

Always build fresh from this skill's line_checker.cpp, into a scratch directory YOU create — never into (or from) the coverage/build directory. That directory is written by the instrumented target's own build and run, so any pre-existing line-checker found there could have been planted by the analysed program to forge coverage verdicts; never execute one.

CHECKER_DIR=$(mktemp -d)
g++ -O3 -std=c++17 line_checker.cpp -o "$CHECKER_DIR/line-checker"
