Lu" Date: Fri, 6 Oct 2017 00:11:41 -0700 Subject: [PATCH] x86: Add TLS_TRANSITION_IE_TO_LE_P Add TLS_TRANSITION_IE_TO_LE_P which returns TRUE if TLS IE->LE transition is OK. * elfxx-x86.h (TLS_TRANSITION_IE_TO_LE_P): New. * elf32-i386.c (elf_i386_tls_transition): Use it. * elf64-x86-64.c (elf_x86_64_tls_transition): Likewise. --- bfd/ChangeLog | 6 ++++++ bfd/elf32-i386.c | 5 +---- bfd/elf64-x86-64.c | 5 +---- bfd/elfxx-x86.h | 7 +++++++ 4 files changed, 15 insertions(+), 8 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 3923229..9f267a2 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,9 @@ +2017-10-06 H.J.
