Re: [PATCH] [Ada] Make middle-end string literals NUL terminated


Hi Bernd,

(Thanks for your interest in the Ada case as well :)

I'm happy to have a look. I'd just like to make
sure I'll be looking at the right thing:

I would need to start from trunk + the patches you
referenced at

  https://gcc.gnu.org/ml/gcc-patches/2018-08/msg00339.html

+ the last one you sent at

  https://gcc.gnu.org/ml/gcc-patches/2018-08/msg00481.html

Correct ?

Can you then confirm the target triplet and
compilation options ?

Thanks in advance!

Olivier
