Very simple 6502 simulator for running llvm-mos-compiled ELF binaries with remote debugging support, based on arv4t example of gdbstub project
save following test program as test.c:
#include <stdio.h>
int main() {
printf("Hello from llvm-mos!\n");
}
and compile it with:
mos-sim-clang -g test.c -O1
It should produce a.out.elf binary.
use following .lldbinit file to upload ELF binary to emulator
target create a.out.elf
platform select remote-gdb-server
platform connect connect://localhost:9001
platform put-file a.out.elf a.out.elf
platform disconnect
gdb-remote localhost:9001
and run lldb to start debugging.
You may also need to add following line:
settings set target.load-cwd-lldbinit true
to enable loading .lldbinit from current directory
