https://bugs.gentoo.org/641474 From e764842a5c6ae3aa81be7c8c2b710d92404b9590 Mon Sep 17 00:00:00 2001 From: amodra Date: Tue, 29 Aug 2017 08:27:02 +0000 Subject: [PATCH] [RS6000] linux startfile/endfile These need to match the gnu-user.h definitions to support --enable-default-pie. Otherwise we end up linking the wrong startup files when defaulting to PIE. PR target/81170 PR target/81295 * config/rs6000/sysv4.h (STARTFILE_LINUX_SPEC): Upgrade to match gnu-user.h startfile. (ENDFILE_LINUX_SPEC): Similarly. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/branches/gcc-6-branch@251405 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/ChangeLog | 7 +++++++ gcc/config/rs6000/sysv4.h | 46 ++++++++++++++++++++++++++++------------------ 2 files changed, 35 insertions(+), 18 deletions(-) diff --git a/gcc/config/rs6000/sysv4.h b/gcc/config/rs6000/sysv4.h index ba35fd27d0f..f81ba6d1514 100644 --- a/gcc/config/rs6000/sysv4.h +++ b/gcc/config/rs6000/sysv4.h @@ -752,24 +752,34 @@ ENDIAN_SELECT(" -mbig", " -mlittle", DEFAULT_ASM_ENDIAN) #define CRTOFFLOADEND "" #endif -#ifdef HAVE_LD_PIE -#define STARTFILE_LINUX_SPEC "\ -%{!shared: %{pg|p|profile:gcrt1.o%s;pie:Scrt1.o%s;:crt1.o%s}} \ -%{mnewlib:ecrti.o%s;:crti.o%s} \ -%{static:crtbeginT.o%s;shared|pie:crtbeginS.o%s;:crtbegin.o%s} \ -" CRTOFFLOADBEGIN -#else -#define STARTFILE_LINUX_SPEC "\ -%{!shared: %{pg|p|profile:gcrt1.o%s;:crt1.o%s}} \ -%{mnewlib:ecrti.o%s;:crti.o%s} \ -%{static:crtbeginT.o%s;shared|pie:crtbeginS.o%s;:crtbegin.o%s} \ -" CRTOFFLOADBEGIN -#endif - -#define ENDFILE_LINUX_SPEC "\ -%{shared|pie:crtendS.o%s;:crtend.o%s} \ -%{mnewlib:ecrtn.o%s;:crtn.o%s} \ -" CRTOFFLOADEND +/* STARTFILE_LINUX_SPEC should be the same as GNU_USER_TARGET_STARTFILE_SPEC + but with the mnewlib ecrti.o%s selection substituted for crti.o%s. */ +#define STARTFILE_LINUX_SPEC \ + "%{shared:; \ + pg|p|profile:gcrt1.o%s; \ + static:crt1.o%s; \ + " PIE_SPEC ":Scrt1.o%s; \ + :crt1.o%s} \ + %{mnewlib:ecrti.o%s;:crti.o%s} \ + %{static:crtbeginT.o%s; \ + shared|" PIE_SPEC ":crtbeginS.o%s; \ + :crtbegin.o%s} \ + %{fvtable-verify=none:%s; \ + fvtable-verify=preinit:vtv_start_preinit.o%s; \ + fvtable-verify=std:vtv_start.o%s} \ + " CRTOFFLOADBEGIN + +/* ENDFILE_LINUX_SPEC should be the same as GNU_USER_TARGET_ENDFILE_SPEC + but with the mnewlib ecrtn.o%s selection substituted for crtn.o%s. */ +#define ENDFILE_LINUX_SPEC \ + "%{fvtable-verify=none:%s; \ + fvtable-verify=preinit:vtv_end_preinit.o%s; \ + fvtable-verify=std:vtv_end.o%s} \ + %{static:crtend.o%s; \ + shared|" PIE_SPEC ":crtendS.o%s; \ + :crtend.o%s} \ + %{mnewlib:ecrtn.o%s;:crtn.o%s} \ + " CRTOFFLOADEND #define LINK_START_LINUX_SPEC "" -- 2.15.1
