If it was used consistently, it might work better.. but yeah.. I gave up on a mass edit and hacked ansidecl.h instead. I'm about to open a bug summarizing my experience with configure -enable-build-with-cxx in 4.5.1 so far. At least what doesn't work. It also works fine with g++ 4.x. Problems with g++ 3.3 and SunStudio 12 C++. ENUM_BITFIELD is a problem. obstack_free subtracting void* or such is a problem. abs(wide int) is a problem => ambiguous between overloads.. - Jay ---------------------------------------- > Date: Sat, 6 Nov 2010 15:37:43 +0100 > Subject: Re: ATTRIBUTE_UNUSED => ARG_UNUSED > From: richard.guenther@gmail.com > To: jay.krell@cornell.edu > CC: gcc-patches@gcc.gnu.org > > On Fri, Nov 5, 2010 at 11:48 PM, Jay K wrote: > > > >> for a in *.h *.c; do perl -pi.bak -e "s/([A-Za-z0-9_]+) ATTRIBUTE_UNUSED/ARG_UNUSED(\1)/" $a; done > > > > eek, careful there, it breaks stuff, e.g. genautomata.c > > I think people are more used to ATTRIBUTE_UNUSED syntax, so I'd rather > get rid of ARG_UNUSED > (what's its advantage?) > > Richard. > > > - Jay > > > > > > ---------------------------------------- > >> From: jay.krell > >> To: gcc-patches > >> Subject: ATTRIBUTE_UNUSED => ARG_UNUSED > >> Date: Fri, 5 Nov 2010 22:25:14 +0000 > >> > >> > >> ATTRIBUTE_UNUSED => ARG_UNUSED > >> In 4.5.1, configure -enable-build-with-cxx, with older g++: > >> > >> diff -u -r1.1.1.1 directives.c > >> --- directives.c 28 May 2010 05:49:44 -0000 1.1.1.1 > >> +++ directives.c 5 Nov 2010 21:44:04 -0000 > >> @@ -1,3 +1,5 @@ > >> @@ -621,8 +623,8 @@ > >> /* Undefine a single macro/assertion/whatever. */ > >> > >> static int > >> -undefine_macros (cpp_reader *pfile ATTRIBUTE_UNUSED, cpp_hashnode *h, > >> - void *data_p ATTRIBUTE_UNUSED) > >> +undefine_macros (cpp_reader *ARG_UNUSED(pfile), cpp_hashnode *h, > >> + void *ARG_UNUSED(data_p)) > >> { > >> /* Body of _cpp_free_definition inlined here for speed. > >> Macros and assertions no longer have anything to free. */ > >> j > >> > >> > >> and so on. > >> > >> > >> for a in *.h *.c; do perl -pi.bak -e "s/([A-Za-z0-9_]+) ATTRIBUTE_UNUSED/ARG_UNUSED(\1)/" $a; done > >> > >> > >> - Jay > > > >
