| PmReturn_t | interp_reschedule (void) |
| PmReturn_t | interp_addThread (pPmFunc_t pfunc) |
| void | interp_setRescheduleFlag (uint8_t boolean) |
VM interpreter header.
| #define FP (gVmGlobal.pthread->pframe) |
frame pointer ; currently for single thread
| #define GET_ARG | ( | ) | mem_getWord(MS, &IP) |
gets the argument (S16) from the instruction stream
| #define IP (FP->fo_ip) |
instruction pointer
| #define MP (gVmGlobal.pmod) |
main module pointer (referred to by root frame)
| #define MS (FP->fo_memspace) |
memspace where the frame's func's CO came from
| #define NATIVE_GET_LOCAL | ( | n | ) | (gVmGlobal.nativeframe.nf_locals[n]) |
gets the nth local var from the native frame locals
| #define NATIVE_GET_NUM_ARGS | ( | ) | (gVmGlobal.nativeframe.nf_numlocals) |
gets the number of args passed to the native fxn
| #define NATIVE_GET_PFRAME | ( | ) | (*ppframe) |
gets a pointer to the frame that called this native fxn
| #define NATIVE_SET_TOS | ( | pobj | ) |
Value:
(gVmGlobal.nativeframe.nf_stack = \ (pobj))
| #define PM_POP | ( | ) | (*(--SP)) |
pops an obj from the stack
| #define PM_PUSH | ( | pobj | ) | (*(SP++) = (pobj)) |
pushes an obj on the stack
| #define SP (FP->fo_sp) |
argument stack pointer
| #define STACK | ( | n | ) | (*(SP - ((n) + 1))) |
index into stack; 0 is top, 1 is next
| #define TOS (*(SP - 1)) |
top of stack
| #define TOS1 (*(SP - 2)) |
one under TOS
| #define TOS2 (*(SP - 3)) |
two under TOS
| #define TOS3 (*(SP - 4)) |
three under TOS
| typedef enum PmCompare_e PmCompare_t |
COMPARE_OP enum. Used by the COMPARE_OP bytecode to determine which type of compare to perform. Must match those defined in Python.
| enum PmBcode_e |
Byte code enumeration
| enum PmCompare_e |
COMPARE_OP enum. Used by the COMPARE_OP bytecode to determine which type of compare to perform. Must match those defined in Python.
| PmReturn_t interp_addThread | ( | pPmFunc_t | pfunc | ) |
Creates a thread object and adds it to the queue of threads to be executed while interpret() is running.
The given obj may be a function, module, or class. Creates a frame for the given function.
| pfunc | Ptr to function to be executed as a thread. |
| PmReturn_t interp_reschedule | ( | void | ) |
Selects a thread to run and changes the VM internal variables to let the switch-loop execute the chosen one in the next iteration. For the moment the algorithm is primitive and will change the thread each time it is called in a round-robin fashion.
| void interp_setRescheduleFlag | ( | uint8_t | boolean | ) |
Sets the reschedule flag.
| boolean | Reschedule on next occasion if boolean is true; clear the flag otherwise. |
| PmReturn_t interpret | ( | const uint8_t | returnOnNoThreads | ) |
Interprets the available threads. Does not return.
| returnOnNoThreads | Loop forever if 0, exit with status if no more threads left. |
