Hi Guys, since I got a few complaints about giving minor
status updates in the announce group, I am opening this thread.
I will start with giving an overview of what works and what
does not work.
Currently the only basic type you can do arithmetic on is int.
Altough you can compare longs since a few days.
These are the constructs that will work.
- foreach on static arrays strings and range-foreach (those
kinds (0 .. 64)).
- switches (even deeply nested ones)
- for and while loops
- ternary expressions (? :)
- if and else statements (as long as you don't use && and || )
- lables and gotos
- arithmetic expressions as well as post and pre increment and
decrement
Constructs that will not work (but are actively worked on)
- assignment to static array cells
- long ulong arithmetic.
- function calls
- dynamic arrays and slices
- pointers
- structs
- && and ||
- sliceing
Constructs that will not work and are futher down the list.
- classes
- closures
- boundschecks
- asserts
Please note that there will probably be bugs all over the
place.
So even the working features might not be working completely.
Remember those numbers ?
[root@localhost dmd]# time src/dmd -c testSettingArrayLength.d
-bc-ctfe
2147385345u
536821761u
4294639619u
real 0m0.114s
user 0m0.110s
sys 0m0.003s
This is how they look like after my performance fixes:
real 0m0.047s
user 0m0.043s
sys 0m0.000s
Disregard That!
I wasn't paying attention
The lower numbers are produced by ldc!
The performance fixes did lower the overall overhead even more
though.
Which means bytecode generation will not even show up among the
top 50 functions in dmd,
