| /* |
| * System call like services offered by the simulator host. |
| * These are modeled after the Linux 2.4 kernel system calls |
| * for Xtensa processors. However not all system calls and |
| * not all functionality of a given system call are implemented, |
| * or necessarily have well defined or equivalent semantics in |
| * the context of a simulation (as opposed to a Unix kernel). |
| * |
| * These services behave largely as if they had been invoked |
| * as a task in the simulator host's operating system |
| * (eg. files accessed are those of the simulator host). |
| * However, these SIMCALLs model a virtual operating system |
| * so that various definitions, bit assignments etc |
| * (eg. open mode bits, errno values, etc) are independent |
| * of the host operating system used to run the simulation. |
| * Rather these definitions are specific to the Xtensa ISS. |
| * This way Xtensa ISA code written to use these SIMCALLs |
| * can (in principle) be simulated on any host. |
| * |
| * Up to 6 parameters are passed in registers a3 to a8 |
| * (note the 6th parameter isn't passed on the stack, |
| * unlike windowed function calling conventions). |
| * The return value is in a2. A negative value in the |
| * range -4096 to -1 indicates a negated error code to be |
| * reported in errno with a return value of -1, otherwise |
| * the value in a2 is returned as is. |
