struct Test3 { uint32_t c; uint8_t d; } MyStruct2; In this case, the memory layout will be as shown in Figure 7. As you can see, three padding bytes are added to the end of the memory layout to increase the size of the structure to 8 bytes. This will make the structure ...
when you reach the end of the loop in line 5, where you write out the GOTO that jumps back to the condition, you simply change the destination of line 2 after the fact. This is usually fairly easy if you write a function for parsing every syntax element. Take the following C-like pr...
