Summary
tslangand get source-level breakpoints/stepping in JIT-compiled TypeScript on Linux, using the existing GDB JIT registration in the LLJIT object linking layer.--difor debug info, no--optsince GDB registration is only enabled without optimizations) and notes thedebugger;statement as an alternative trap-based breakpoint.Test plan
gdb --args tslang --di hello.ts, set a pending breakpoint on a.tsline, ran, and confirmed GDB stopped at the correct TypeScript source line with line context shown.
