HI. I used wasm-opt manually to optimize wasm binary. On last step I used Oz to finalize optimizations. My problem is that after Oz function indexes is changed and I can't get symbols map to restore function names. How I can map new function indexes to old one (from symbols file).
In other words: 1) I have bin.wasm from emscripten with symbols file. E.g. for one function: export __GLOBAL__sub_I_Runtime_BaseClasses_0_cpp (func $3425) - 3809 2) I do some buisness releated optimizations (with wasm-opt) that didn't change function indexes, after this, I still have export __GLOBAL__sub_I_Runtime_BaseClasses_0_cpp (func $3425) - 3809 3) Next I finalize build with wasm-opt -Oz, after it indexes was changed (I think because of dead code elimination), and I have export "__GLOBAL__sub_I_Runtime_BaseClasses_0_cpp" (func $1637) - 1997 I need some flag for Oz, that told generates mapping for new indexes, like $1637: $3425 then I can restore original function names. I think some flag or option to do it should be already there, because emscripten do this in some way. What is the best way to build this mappings? -- You received this message because you are subscribed to the Google Groups "emscripten-discuss" group.
