Anyone see anything being removed that would be missed? Is the NEWS bit OK? ----- From f6e488ad019b8d26c87fa77fe190808bd289b73a Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Fri, 3 Oct 2014 10:12:44 +0100 Subject: [PATCH] Delete Irix support This does most of the mechanical removal. IOW, the easy part. This doesn't touch procfs.c as that'd be a harder excision, potentially affecting Solaris. mips-tdep.c is left alone. E.g., I didn't delete the GDB_OSABI_IRIX enum value, nor references to it in mips-tdep.c. Some comments mentioning Irix ABIs may still be relevant and I wouldn't know what to do with them. in That can always be done on a separate pass, preferably by someone who can test on MIPS. Likewise, mipsread.c is left alone. IIUC, pieces may be necessary for PDR records on Linux. I didn't remove a reference to irix in testsuite/lib/future.exp, as I believe that code is imported from DejaGNU. Built and tested on x86_64 Fedora 20, with --enable-targets=all. Tested that building for --target=mips-sgi-irix6 on x86_64 Fedora 20 fails with: checking for default auto-load directory... $debugdir:$datadir/auto-load checking for default auto-load safe-path... $debugdir:$datadir/auto-load *** Configuration mips-sgi-irix6 is obsolete. *** Support has been REMOVED. make[1]: *** [configure-gdb] Error 1 make[1]: Leaving directory `/home/pedro/gdb/mygit/build-irix' make: *** [all] Error 2 gdb/ 2014-10-03 Pedro Alves * Makefile.in (ALL_TARGET_OBS): Remove mips-irix-tdep.o and solib-irix.o.
