But the marking could get disabled if ".set nomacro" was on for > a branch, couldn't it? Err... Yes, indeed, this is already the case, now that I think of it. Only when the branch is a relaxation candidate does it become the end of a variable-sized frag. Branches within nomacro sections are not relaxed in the current implementation, so we handle them just as before. -- Alexandre Oliva Enjoy Guarana', see http://www.ic.unicamp.br/~oliva/ Red Hat GCC Developer aoliva@{redhat.com, gcc.gnu.org} CS PhD student at IC-Unicamp oliva@{lsd.ic.unicamp.br, gnu.org} Free Software Evangelist Professional serial bug killer
