From 355bc7f736fb4cbc81979a7fce674858173f34cf Mon Sep 17 00:00:00 2001 From: Samuel Thibault Date: Tue, 1 Feb 2022 18:32:19 +0000 Subject: [PATCH] SET_RELHOOK: merge i386 and x86_64, and move to sysdeps/mach/hurd/x86 It is not Hurd-specific, but H.J. Lu wants it there. Also, dc.a can be used to avoid hardcoding .long vs .quad and thus use the same implementation for i386 and x86_64. --- sysdeps/generic/set-hooks-arch.h | 2 +- .../{i386 => mach/hurd/x86}/set-hooks-arch.h | 4 +-- sysdeps/x86_64/set-hooks-arch.h | 28 ------------------- 3 files changed, 3 insertions(+), 31 deletions(-) rename sysdeps/{i386 => mach/hurd/x86}/set-hooks-arch.h (94%) delete mode 100644 sysdeps/x86_64/set-hooks-arch.h diff --git a/sysdeps/generic/set-hooks-arch.h b/sysdeps/generic/set-hooks-arch.h index 9101646d70..f04e11abfb 100644 --- a/sysdeps/generic/set-hooks-arch.h +++ b/sysdeps/generic/set-hooks-arch.h @@ -21,7 +21,7 @@ #define _SET_HOOKS_ARCH_H /* Define SET_RELHOOK to a variant of text_set_element that records a relative - offset rather than an absolute address.
