* libguile/frames.c (scm_frame_source): Instead of assuming that scm_frame_procedure is correct, use the IP to get the source. (scm_frame_instruction_pointer): Return an absolute value instead of assuming that slot 0 is correct. (It isn't, when preparing for a tail call.) * libguile/programs.h: * libguile/programs.c (scm_find_source_for_addr): New internal helper. * module/system/repl/debug.scm (print-registers): Readably print absolute instruction pointers. * module/system/vm/coverage.scm: Complete rewrite to use absolute IP's. We can't assume that frame-procedure is cheap if it is correct, or correct if it is cheap. Anyway using the address is better anyway. (coverage-data->lcov): Disable per-function info temporarily. (loaded-modules, module-procedures, closest-source-line) (closed-over-procedures): Remove these. Instead of going from procedures to source info, now we go from ELF image to source info. * module/system/vm/debug.scm (debug-context-length): New interface. * module/system/vm/program.scm (source-for-addr): New internal helper.
