Hi all, I am a little stuck and would appreciate if someone could help. I am simulating in Gem5 syscall emulation mode and I've made some modifications to the CPU model to support some additional instructions (RISC-V). To compile programs using the new instructions, I also have a clang compiler that places the instructions. It is important that *every* piece of code that is executed on the core goes through my own compiler. I compiled Newlib for libc support. Unfortunately, the _write() function (that is, the function that executes the syscall) has to be implemented manually. Is there a way to print to stdout in syscall emulation mode where I compile the libc myself? What would the _write() function have to implement? Is there any other way to print during simulation?
>From other platforms I am used to solutions like "write at a specific address" but I couldn't find anything like that for Gem5. I realize that the problem is very unusual, I would appreciate any help. Thanks!
