From 491bb0858e2d7edc36ced616e846803671d8db75 Mon Sep 17 00:00:00 2001 From: Zack Weinberg Date: Tue, 30 May 2017 21:05:04 -0400 Subject: Avoid tickling a linker bug from microblaze pt-vfork.S. libpthread used to have its own vfork implementation that differed from libc's only in having a pointless micro-optimization. There is no longer any use to having a separate copy in libpthread, but the historical ABI requires a compatibility shim. microblaze was trying to be slightly too clever about how it did this, and tickled a linker bug. The linker bug should get fixed eventually, but there's no reason for us to keep tickling it in the meantime. This doesn't reuse the generic pt-vfork.c because microblaze doesn't have IFUNC support yet, and it doesn't reuse aarch64/pt-vfork.c because that fails to generate a tailcall (with GCC 7.1.1). * sysdeps/unix/sysv/linux/microblaze/pt-vfork.S: Don't include alpha/pt-vfork.S. Provide own compat shim for vfork and __vfork. * sysdeps/unix/sysv/linux/microblaze/vfork.S: Add __libc_vfork alias. * sysdeps/unix/sysv/linux/microblaze/localplt.data: libpthread.so no longer references __errno_location. --- ChangeLog | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index c0d9d6d..d0bed8a 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,11 @@ +2017-06-01 Zack Weinberg + + * sysdeps/unix/sysv/linux/microblaze/pt-vfork.S: Don't include + alpha/pt-vfork.S.
