Nice of you to start some discussion on these flags. I use them myself
(and a few others that seem to affect code size) in a 'tiny' target
inside the D Makefile I use.
Currently it looks like this:
dmd <sources,directory,bin> -m32 -O -release -noboundscheck
-L--strip-all -L-O1 -L-znodlopen -L-znorelro
-L--no-copy-dt-needed-entries -L--relax -L--sort-common -L--gc-sections
-L-lrt -L--as-needed
strip <bin> -R .comment -R .note.ABI-tag -R .gnu.hash -R .gnu.version
-R .jcr -R .got
That's not even funny, I know :D
How far down do you get in terms of size with this?
I've just installed 2.057 and there were changes that affect code size, so
I'll test it once more:
Simple "Hello, world!"
