warning if compiling and linking using [-no]-pie #95108

Open nolange opened 5 months ago

nolange commented 5 months ago

When linking for windows you will get false warnings, see:

echo "int main() {return 0;}" | clang++ --target=x86_64-windows-gnu -x c++ -pie -

Will result in:

clang++: warning: argument unused during compilation: '-pie' [-Wunused-command-line-argument]

Despite the clang invocation doing linking. When targeting Linux there is no warning.

Using Clang 18.1.6 on Debian x86_64.
