EMCC version 1.38.31
How to properly compile C to asm.js, with a sample from Wikipedia
<https://en.wikipedia.org/wiki/Asm.js#Code_generation>.
// input.c
int f(int i) {
return i + 1;
}
Expected result:
// output.js
function f(i) {
"use asm";
i = i | 0;
return (i + 1) | 0;
}
I have tried to compile it with(see below) and generates huge JavaScript
file with ~5K lines of code
emcc input.c -o output.js \
-s INVOKE_RUN=0 \
-s EXPORTED_FUNCTIONS="['_f']" \
-s WASM=0 # causes the compiler to target asm.js
