Hi. I need some explanation about minify stage of native optimizer. I know that when I use at least O2 flag all function names are mangled (minified). Also I know that -g1 or -profiling-funcs permits name mangling. But in this case result js file is much bigger. I wonder why there are no option to provide source maps for mangled names in O2 mode. In that case I still can use small js file + understandable function names in profiler.
I trying to build my own profiler that works on js level. To do this I use uglifyjs. I use it to parse emscripten js file, and modify all functions to add time counters in their bodies. I can't use browser profiler, because on ios it never works :(. I get the first version of my profiler, and it works well! But I have problem with minifying transformed js. Uglifyjs, does nothing. For example, I build project with -O2 the result is 8.6mb. I build it again with -O2 -profiling-funcs the result is ~14mb. I get this js and use uglifyjs to mangle names (-m flag), result still ~14mb. Why so? I except that result should be near 8.6mb. Btw, to finish work with profiler I need to get mapping from O2 function names to original names (like in -profiling-funcs mode). Is it possible to generate it in some way? -- You received this message because you are subscribed to the Google Groups "emscripten-discuss" group.
