CTFE Status

[Stefan Koch via Digitalmars-d]

Here is a small demostration of the performance increase :

[root at localhost dmd]# time src/dmd -c testSettingArrayLength.d > 
x 2> x

real	0m0.199s
user	0m0.180s
sys	0m0.017s
[root at localhost dmd]# time src/dmd -c testSettingArrayLength.d 
-bc-ctfe > x 2> x

real	0m0.072s
user	0m0.050s
sys	0m0.020s

Please note that newCTFE only spends 15 ms inside the evaluation, 
most time is spent clearing the 2^^24 Bytes of heap-memory to 
zero.

The sourcode of testSettingArrayLength is
uint[] MakeAndInitArr(uint length)
{
     uint[] arr;
     arr.length = length;

     foreach(i;0 .. length)
     {
         arr[i] = i + 3;
     }
     return arr;
}

static assert(MakeAndInitArr(ushort.max).length == ushort.max);
