- If not, call `SIMIX_process_yield` to give back the control to maestro
- ========== KERNEL MODE ==========
- `SIMIX_simcall_handle` large switch (on simcall) doing for each:
- - `SIMIX_pre_<name>(simcall, <args>)`
+ - `simcall_HANDLER_<name>(simcall, <args>)`
- `SIMIX_simcall_answer(simcall)`
To simplify the simcall creation, a python script generates most of
the code and give helpers for the remaining stuff. That script reads
-the simcall definitions from src/simix/simcalls.in and generates the
-following files:
+the simcall definitions from src/simix/simcalls.in, checks that both
+`simcall_<name>()` and `simcall_HANDLER()` are defined somewhere, and
+generates the following files:
- smx_popping_accessors.h:
Helper functions to get and set simcall arguments and results
Definitions of `simcall_names[]` (debug name of each simcall), and
SIMIX_simcall_enter() that deals with the simcall from within the kernel
-Furthermode if the simcall_<name> or the SIMIX_pre_<name> function are missing,
-a warning will show up with a prototype of the corresponding fonction to fill.
-
The simcall.in file list all the simcalls in sections. A line starting by "##"
define a new section which will be replace by a "ifdef" in the generated code.
There is a simcall by line which follow this format:
