But I have heard mixed results (not that I've tried it).
Should be as easy as
dflags "--DRT-gcopt=gc:precise"
right?
How do I specify a druntime flag such as
--DRT-gcopt=gc:precise
when running with dub as
dub run --compiler=dmd --build=unittest
?
The precise GC flag was introduced in verison 2.085.0

That would be passed to dmd, not to the build executable upon
running.
You mean wise versa, right?

Note in particular the blocksize argument. I set it to 1M but
by default it's 512 bytes. If you use strace with the command
above you'll see a series of write() calls, each writting 1M of
null bytes to testfile. That's the main

I don't see how that can necessarily be faster. A LUT can give
full 64-bit precision with one operation. The CORDIC needs
iteration, at least 10 to be of any use. LUT's are precision

Use a size that is 2^n, then mask the index and hopefully that
