From a4aa319f7c19e564dced3daeb7222c9315af936c Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Sat, 18 Aug 2018 23:58:45 +0000 Subject: [PATCH 12/12] static-pie in gcc-8 -static means static non-pie, even if -pie or -static-pie are specified, -static-pie can be used to build static pie. in musl toolchains -static -pie always meant static pie, so this patch fixes the link specs accordingly, the new -static-pie is just an alias to -static -pie. --- gcc/common.opt | 4 ++-- gcc/config/gnu-user.h | 12 +++++------- gcc/config/rs6000/sysv4.h | 11 +++++------ gcc/gcc.cc | 6 +++--- 4 files changed, 15 insertions(+), 18 deletions(-) diff --git a/gcc/common.opt b/gcc/common.opt index b52ef0b38c8..0ce5857e01d 100644 --- a/gcc/common.opt +++ b/gcc/common.opt @@ -3669,11 +3669,11 @@ Driver no-pie Driver RejectNegative Negative(shared) -Don't create a dynamically linked position independent executable. +Don't create a position independent executable. pie Driver RejectNegative Negative(no-pie) -Create a dynamically linked position independent executable. +Create a position independent executable. static-pie Driver RejectNegative Negative(pie) diff --git a/gcc/config/gnu-user.h b/gcc/config/gnu-user.h index 8620de3e42d..235328a2642 100644 --- a/gcc/config/gnu-user.h +++ b/gcc/config/gnu-user.h @@ -51,13 +51,12 @@ #define GNU_USER_TARGET_STARTFILE_SPEC \ "%{shared:; \ pg|p|profile:%{static-pie:grcrt1.o%s;:gcrt1.o%s}; \ - static:crt1.o%s; \ - static-pie:rcrt1.o%s; \ + static|static-pie:%{" PIE_SPEC ":rcrt1.o%s;:crt1.o%s}; \ " PIE_SPEC ":Scrt1.o%s; \ :crt1.o%s} " \ GNU_USER_TARGET_CRTI " \ - %{static:crtbeginT.o%s; \ - shared|static-pie|" PIE_SPEC ":crtbeginS.o%s; \ + %{shared|" PIE_SPEC ":crtbeginS.o%s; \ + static:crtbeginT.o%s; \ :crtbegin.o%s} \ %{fvtable-verify=none:%s; \ fvtable-verify=preinit:vtv_start_preinit.o%s; \ @@ -76,8 +75,7 @@ see the files COPYING3 and COPYING.RUNTIME respectively.
