built a working pacman with the mame0217 tag and emscripten 1.38.48 (commit c56422590bb911603529052b7bd78e6ca3c9fa27) |

looks like there's a major emscripten update so I'll give that a whirl |

I think running wasm2js in the debugger was a mistake |

unfortunately it happened before the usual messages from MAME, so it's not the same error |

the point where the exception occurs is where there is an expected exception as part of the startup process that's supposed to be whitelisted |
|

|
DFJustin |
(judging by the -verbose output at least) |

looks like I just need to pass the flags earlier in the compile process |

I don't follow the webgl side of things that closely myself, but looks like glBeginQuery is under WebGL2, so you need to set MAX_WEBGL_VERSION=2. We refactored those flags recently. But the old flag USE_WEBGL2 should also work, so it's odd if it doesn't. |
|
22:06
🔗
|
DFJustin |
kripken_: I think the issue I'm getting is just a matter of needing to set EXCEPTION_CATCHING_WHITELIST during the codegen phase |
|

DFJustin |
after switching from fastcomp to upstream |
|
22:06
🔗
|
kripken_ |
DFJustin: Oh, yes, that's definitely a change with the new backend. Yeah, it does codegen during the compile stage now (like a regular C compiler), so that flags need to be set there too for exceptions etc. |
|
22:07
🔗
|
DFJustin |
there are a bunch of new undefined gl messages but there were some of those before too that never seemed to matter |
|

i saw an issue filed on a wasm2js segfault with MAME earlier today, maybe that was from someone here? I'll take a look later when I'm at my main machine |
