You can generate a breakpoint in multiple ways by using DebugBreak() from Torque, from the CodeStubAssembler, as a node in a TurboFan pass, or directly using an assembler.

However, if running with a simulator, a breakpoint instruction in generated code will instead drop you into the simulator debugger. Natively, breakpoint instructions cause the program to halt with a SIGTRAP signal, allowing you to debug the issue with gdb. You can start the debugger immediately from the command line after n instructions: out/bug/d8 -stop_sim_at # Or out/arm.debug/d8 for a 32-bit build.Īlternatively, you can generate a breakpoint instruction in the generated code: You may also build the optdebug configuration as the debug may be a little slow, especially if you want to run the V8 test suite.

64-bit: Debug() Compiling for Arm using the simulator #īy default on an x86 host, compiling for Arm with gm will give you a simulator build: gm bug # For a 64-bit build or.

In this case, feel free to implement them and submit the code! Only the features used by V8 are implemented, and you might encounter unimplemented features or instructions. Please note that this simulator is designed for V8 purposes. The simulator fully supports the debugging of generated code.

No cross or native compilation is needed.

It is convenient as it allows you to test code generation without access to actual hardware.

The simulator and debugger can be very helpful when working with V8 code generation.

Research Arm debugging with the simulator.
