You should be getting these OOTB - CMake already does -O3 for Release builds and dt already sets -march=native if you don’t do -DBINARY_PACKAGE_BUILD=ON (off by default).

Definitely not INTENTIONALLY changing anything! 
I followed kofa’s advice and did:
git clean -d -f -x
git pull --rebase
git submodule update
…which got me to v4.6.0-dirty
Not sure what I did wrong. From what you guys have said, that should have got rid of the dirty flag. If anyone can see where I went wrong, sing out!
Thanks in advance.
My current prompt in the terminal looks like this:
~/Downloads/darktable/darktable #release-4.6.0 !1
I suspect that that “!1” on the end signifies 1 commit different from official, and hence the dirty flag. Is that the case?
What does git status say?
~/Downloads/darktable/darktable #release-4.6.0 !1 git status INT ✘
HEAD detached at release-4.6.0
Changes not staged for commit:
(use “git add …” to update what will be committed)
(use “git restore …” to discard changes in working directory)
modified: src/tests/integration (new commits)
no changes added to commit (use “git add” and/or “git commit -a”)
Yep, your tree is not in a good state, you have a mix of master branch and 4.6.0 tag. Which one do you actually want to build?
4.6.0 for now.
Then you need to actually check out that branch, and then reset to tag:
git checkout darktable-4.6.x
git reset --hard release-4.6.0
What is the status after these?

Running the build script now.

Thanks for your assistance, kmilos!

This is what I do to compile and install:
Change to my darktable-git directory.
Inside I have this PKGBUILD file:

package() {
cd $_gitname
make -C build DESTDIR=$pkgdir install
ln -s darktable/libdarktable.so "${pkgdir}"/usr/lib/libdarktable.so
}
Then, to compile, create the package and install:
makepkg -scf
sudo pacman -U darktable-git-...
If I want to directly compile, create the package and install, I use this one-liner:
makepkg -scfi
A little bit late as I see but anyway, I hope it helps you.

Now, if you ever update (pull) again, or switch (checkout) to a different branch, the key is to remember to run git submodule update --init --recursive immediately after so the tree stays in sync.

Many thanks!
