I wrote simple proof of concept library. The main aim is to
reduce GC usage and improve data locality by replacing dynamic
array for small immutable arrays.
You can find more info here:
* wiki - https://bitbucket.org/sibnick/inplacearray/wiki/Home
* source code - https://bitbucket.org/sibn
This reminds me of another useful library here:
https://bitbucket.org/infognition/dstuff/src/
See gcarena.d
Thanks for link.
The main difference is that I want elimanate pair pointer+data at
all. It is more effective to store small array as value type.

It is big problem in java. You have pointer to String object with
fields: hashCode and chars array (UTF-16). But every array is
object itself. So it is pointer to object again. There is pointer
compression option in x64 JVM (it uses 32 bits per pointer), but
in any way it is
These guys have independent JVM implementation and used
Conservative GC for many years. As I can see it it is very
similar to d-runtime GC. But their conclusion is: "sooner or
later the absence of knowledge about the liveness of local
variables will lead to problems in production that just cann

I am porting LDC to NetBSD amd64, and I ask advice how to handle
real type. NetBSD has limited support for this type. This type
exists, but standard library does not provide full set of math
functions for it (e.g. sinus, cosinus, and etc). Currently I just
forward all function calls to 64 bits
What is long double on NetBSD/amd64, 64-bit or full 80-bit?
80 bit
but function set is not full e.g.
acos supports long double
http://netbsd.gw.com/cgi-bin/man-cgi?acos+3+NetBSD-7.0
cos does not support long double
http://netbsd.gw.com/cgi-bin/man-cgi?cos+3+NetBSD-7.0

In any case it was not my decision. LDC does not use x87 for math
functions on other OS's.

Currently it looks like it is not possible to use opDispatch for
