2013-04-17Configuring for i386 is no longer supported.Carlos O'Donell
We no longer support configuring for i386, nor do we elide such a configuration to i686. Configuring with i386-* is a failure, and we provide an example of how to fix that. --- 2013-04-17 Carlos O'Donell <carlos@redhat.com> * configure.in: Remove i386 configure warning. Remove i386 case. * configure: Regenerate. * sysdeps/i386/configure.in: Raise error if config_machine is i386. Add example to error message. * sysdeps/i386/configure: Regenerate.
2013-04-06i386: Fail at configure time for i386 builds.Carlos O'Donell
This change does two things: * Treats a target i386-* as if it were i686. * Fails configure if the user is generating code for i386. We no longer support i386 code-generation because the i386 lacks the atomic operations we need in glibc. You can still configure for i386-*, but you get i686 code. You can't build with --march=i386, --mtune=i386 or a compiler that defaults to i386 code-generation. I've added two i386 entries in the master todo list to discuss merging and renaming: http://sourceware.org/glibc/wiki/Development_Todo/Master#i386 The failure modes are fail-safe here. You compile for i386, get i686, and try to run on i386 and it fails. The configure log has a warning saying we elided to i686. There is no situation that I can see where we run into any serious problems. The patch makes the current state better in that we get less confused users and we build successfully in more default configurations. The next enhancement would be to add --march=i?86 as suggested in #c20 of BZ#10062 for any i?86-* builds, which would solve the problem of a 32-bit compiler that defaults to i386 code-gen and glibc configured for i686-* target. Which previously failed at build time, and now will fail at configure time (requires adding --march=i686). Updated NEWS with BZ #10060 and #10062. No regressions. --- 2013-04-06 Carlos O'Donell <carlos@redhat.com> [BZ #10060, #10062] * aclocal.m4 (LIBC_COMPILER_BUILTIN_INLINED): New macro. * sysdeps/i386/configure.in: Use LIBC_COMPILER_BUILTIN_INLINED and fail configure if __sync_val_compare_and_swap is not inlined. * sysdeps/i386/configure: Regenerate. * configure.in: Build for i686 when configured for i386. * configure: Regenerate. * README: Remove i386 reference.

Stop assuming specific path layouts for C++ headers, and instead use an autodetection method that looks for paths with '/[cg]++' in the g++ include list.

2012-10-24change ifunc assembly test to a link testMike Frysinger
The test currently tests the binutils frontend support which passes for all versions of binutils we currently require (2.20+). It doesn't test the backend which is required for ifunc to actually work, and which most targets don't yet support. Change the assembly code so that when we link it, we get a file that has ifunc relocations if the backend supports it. That way we can test to see if binutils supports everything we need.
