Hi.
I'm trying to port phobos2 and druntime2 to OpenBSD 5.1. I found next
problems:
1) D compiler loops with '-O -release' flags. For example:
$ cat test.d
module my_mod;
void MyFunc()
{
int[2] arr;
for (size_t i = 0; i < 2; ++i) {
arr[i] = 1;
}
}
$ pwd
/home/walnut/work/druntime
$ dmd -lib -oflib/libtest.a -m32 -O -release -Isrc ./test.d
^C

It's pretty hard to debug those IR optimization loops.
For now you can workaround them by disabling the OpenBSD4.x <fenv.h>
workarounds in backend/evalu8.c but we should actually fix that some
transformations loop if evalu8 fails.
