@AnotherAURUser Oh, yes. -O3 sometimes is not as effective as -O2. Anyway, let's keep it as it is and follow Arch Linux's custom.

@wszqkzqk as you can see from these tests.. there is no need in these flags. optimized script runs slower than a default one. I am not asking you for anything.

@AnotherAURUser According to Arch Linux's custom, please modify your compiler flags in you own makepkg.conf instead of asking each package to do so.😊

ok @wszqkzqk, here is the answer:

=== SIMPLIFIED OH-MY-POSH BENCHMARK ===

=== BENCHMARK COMPLETE ===

At least now it's possible to find peace, if one craves more optimization.

@AnotherAURUser You can maintain the CFLAGS in your own /etc/pacman.conf instead of change the packaging process.

@AnotherAURUser If there is no strong evidence that the performance improvement is significant, I would prefer to follow Go package guidelines.

guys, what if update code like this:

build() {
    export CC=clang
    export CXX=clang++
    export CGO_CPPFLAGS="${CPPFLAGS} -O3 -march=native -flto"
    export CGO_CFLAGS="${CFLAGS} -O3 -march=native -flto"
    export CGO_CXXFLAGS="${CXXFLAGS} -O3 -march=native -flto"
    export CGO_LDFLAGS="${LDFLAGS} -O3 -march=native -flto"
    export GOFLAGS="-buildmode=pie -trimpath -mod=readonly -modcacherw"

    cd "$pkgname-$pkgver/src"
    go mod download

go build -gcflags="all=-l=4 -d=ssa/check_bce/debug=0" \
  -ldflags="-linkmode=external -s -w \
  -X github.com/jandedobbeleer/oh-my-posh/src/build.Version=$pkgver \
  -X github.com/jandedobbeleer/oh-my-posh/src/build.Date=$(date +%F) \
  -extldflags=-Wl,-O3" \
  -o "$pkgname"
}

will it bring more performance? kinda want to add only optimized things into cachyos

oh-my-posh completion is not supported anymore because of github issue 6103. And I do not find any replacement for it. So I think we may have to remove those completions in package or patch the source to revert the commit .

gcc is not needed in the makedepends field. It's in base-devel.
