Emscripten 4.x removed dynCall_* WASM exports, breaking asyncify
rewind through indirect calls (modal dialogs, event handlers).
Generate JS shims that track Asyncify.exportCallStack and register
in wasmExports so doRewind can find them.
Also fixes empty callback functions ((() => {})) generated by
Emscripten 4.x + pthreads for HTML5 events, pthread entry,
sighandler, async timer, and main loop callbacks.
Build pipeline improvements:
- Stub wasm-opt/finalize in Docker (RAM limits), run on host
- Add setup-emsdk.sh for reproducible Emscripten setup
- Simplify env.sh and version management

# Build script for the WebGL GAL test harness (WASM)
|
|
#
|
|
# This builds a WASM module that renders GAL test scenarios using WebGL,
|
|
# allowing comparison against native OpenGL rendering.
|
|
#
|
|
# Uses a Makefile with direct em++ calls (like build-wasm-test.sh)
|
|
# to avoid emcmake Python 3.10+ requirement.
|
|
#
|
|
# Usage:
|
|
# ./scripts/build-gal-webgl-test.sh # Clean build (default)
|
|
# ./scripts/build-gal-webgl-test.sh --no-clean # Incremental build
|
|
# ./scripts/build-gal-webgl-test.sh --debug # Debug build with source maps
|
|
#
|
|
|
|
# Redirect all output to a log file (re-execs script with redirection)
