LinuxCNC WASM blockers source map
This map records the source basis for the WASM blocker categories used by
analyze-linuxcnc-wasm-blockers.sh and test-linuxcnc-wasm-blockers.sh. It is
a source-link/build guard only; it does not add CNC behavior and must not become smoke parser behavior.
LinuxCNC Source Basis
src/emc/rs274ngc/gcodemodule.cc,canonmodule.cc,interpmodule.cc, andpy*.ccprovide the Python and Boost.Python module binding blockers.src/emc/rs274ngc/interp_python.cc,interp_remap.cc,interp_namedparams.cc,interp_o_word.cc,interp_setup.cc, andrs274ngc_pre.cckeep Python/Boost.Python remap paths as shimmed core sources.src/emc/rs274ngc/interp_base.ccis the core source that still carriesdlopenuse satisfied by the wasm dlfcn shim.src/emc/tooldata/tooldata_mmap.ccis the native mmap backend blocker replaced by the wasm-safe tooldata mmap backend shim.src/emc/rs274ngc/interp_o_word.ccuses native directory traversal for O-word subroutine lookup; browser persistence remains OPFS-only.

Checks
Run:
./check-linuxcnc-wasm-blockers-source-map.sh
./test-linuxcnc-wasm-blockers.sh linuxcnc-rs274-wasm-source-files.txt
./test-native.sh
./test-linuxcnc-source-link.sh
check-linuxcnc-wasm-blockers-source-map.sh keeps this document, the
RS274/WASM manifest, LinuxCNC source anchors, analyzer output, and wasm-safe
shim replacement set synchronized. Python/Boost.Python remap paths remain tracked blockers until they are ported, wrapped, or replaced by source-backed browser-safe LinuxCNC adaptations.
