Step over in your original code now avoids pausing in disassembly (. # Improved stepping behavior in Wasm apps ![]() To test Wasm debugging, install the C/C++ DevTools Support (DWARF) extension and step through the code in the Mandelbrot demo.Ĭhromium issue: 1414289. Understandable function names in call stack.Your original source code, mapped using DWARF debugging information.This experiment lets you pause execution and debug C and C++ code in Wasm apps, with all the debugging information available to you: ![]() For more information, see Debugging WebAssembly with modern tools.
