Hi Guys,
I know I have been quiet about newCTFE for a while, mainly I have been focusing on other features which would make it more important, since a lot of the compile-time of certain companies is not spent in CTFE.
However recently I had the urge to fix an early design mistake in newCTFE.
And that was that newCTFE had no notion of a frame pointer.
Which made it impossible to easily take pointers of locals.
What newCTFE would do when it was asked to take the address of a local variable was to allocate space space on the heap.
Copy the local to the heap.
and then convert the local variable into a pointer to that heap location under the hood.
so
int x = 22;
int* y = &x;
would become:
int x = 22;
void* _mem_y = malloc(x.sizeof);
memcpy(mem_y, &x, z.sizeof);
int* y = cast(int*)mem_y,
&x = y; // this line represents nasty compiler magic
Now however I have the concept of a frame pointer, and things becomes much cleaner
The code above becomes:
int x = 22;
int* y = framePointer + OffsetFromFramePointer(x);
And no nasty syncing of different memory locations is required anymore ;)
Cheers,
Stefan
