The problem is that the second eabi conditional overrides the first (the one for Android). Paolo

Swapping them looks like the right thing to do. Paolo
Hi!

This used to match configurations arm*-[vendor]-linux-androideabi; now it only matches arm*-[vendor]-androideabi, which isn't in use (for a Android system is always based on the Linux kernel, in my understanding).

This is meant to match arm-linux-androideabi, which didn't match anymore after the initial problematic targ change but needs to.

Thr former, but I guess that we want to support the latter as well.

In my reading, the code supported both these before your recent change, and now supports neither, as I reported this morning. With which configurations exactly have you tested your change?

Then, the following case fails, which is expected to yield identical results, with "complete triplets" -- which I took for granted in my reasoning about the Makefile code: $ make target_alias=arm-unknown-linux-androideabi target_alias = »arm-unknown-linux-androideabi« targ = »arm unknown linux androideabi« arch = »arm« manu = »unknown« osys = »linux« not matched My suggested change would make all these work -- however I have not yet had the time to fully digest your other emails with the reasoning that you need configure GCC with non-canonical target and target_alias set differently.

The whole discussion started from wrong premises since, contrary to what the ChangeLog says, neither Pascal nor I have nothing to do with the original, problematic change (see PR ada/57188 for my take on it). We all agree that the mess should be fixed somehow or other and Olivier is working on it.
