Is this preferred performance-wise over `cast(void*)(size_t.max)`?
No, it just works, as opposed to, um... not working ;)

You'd have to do this in the parent. You can duplicate the file

You can use the dlang install.sh script to download LDC and put

hi there,
I just flased a armbain for nanoPi M3.
And, I just installed ldc2-1.2.0 armhf using apt-get. it compiles
d code with combination with gcc armhf and compiled program runs
great even the arch is aarch64.
But I realized that ldc2 is too old, I know that latest ldc2 is
1.8.0.
So,
29 matches
