Asm.js or Javascript source output

[Joe Siebenmann]

I'd just like to know if it's possible to get actual Asm.js or Javascript source code output somewhere from building .c code with emcc and or clang.  I'm not interested in any binaries or WebAssembly output at this time.  I've looked at the output files after a build and see nothing that resembles what the Asm.js or Javascript source might look like.  I have the emsdk working on Windows, and emcc is working.  If it is possible, what commands should I use to get some source output somewhere?  Thanks!

hi Joe,

-s WASM=0 -s LEGACY_VM_SUPPORT=1

also see:
https://github.com/shlomif/fc-solve/blob/master/fc-solve/scripts/Makefile.to-javascript.mak

note that I recall reading it was no longer pure asm.js

Yes, that is correct.  `-sWASM=0` is the setting that disables WebAssembly output and gives you pure JavaScript. 

As Shlomi says, its no longer pure asm.js, just normal JavaScript.  However, that shouldn't matter because legacy browsers/runtimes that don't support wasm most likely don't support the pure form of asm.js anyway.  

cheers,

sam
