Hi Navid,
Did you configure newlib with --enable-target-optspace? For me that is
usually what enables -Os. Otherwise it defaults to -O2. What is your target?
Cheers,
Jon

Subject: Using newlib-1.17.0 with a gcc cross-compiler without "-Os" support
Greetings,
I'm trying to port newlib-1.17.0 for my target. The target's compiler is
based on gcc 2.7.2.3, old yet fuctional.
When I try to make newlib, it tries to call the cross-compiler
(MyMachine-gcc) with size optimization flag (-Os), and it throws an error
with this message: "cc1: Invalid option `-Os'". My target's gcc supports
"-O1", "-O2" and "-O3".
When I configure and make newlib, how can I specify not to use "-Os" ?
Best regards
Navid
