Asm.js optimizations

Asm.js
https://en.wikipedia.org/wiki/Asm.js
Is the pas2js output javascript code optimized like is described in that wiki article, for example:
Code: C
[Select]
[+]
[-]
int
f
(
int
i
)
{
return
i
+
1
;
}
That in Pascal is something like:
Code: Pascal
[Select]
[+]
[-]
function
f
(
i
:
integer
)
:
integer
;
begin
Result
:
=
i
+
1
;
end
;
And translated to Asm.js
Code: Javascript
[Select]
[+]
[-]
function
f
(
i
)
{
i
=
i
|
0
;
return
(
i
+
1
)
|
0
;
}
The extra "|0" converts the variables to int32 acording to the article, so it doesn't use floating point math.

No, but it would be possible to add an option to do so.
I did not take a look what other conversions are needed, so I can't estimate how much work it is.

Hi thanks for the quick response.
Ok it will be great and another reason to choose pas2js instead of emscriptem.
