From db0b3dbc3db1ebdc181cabb758958e501eef2367 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Wed, 5 Jul 2017 10:34:44 -0700 Subject: gcc: Fix libssh_nonshared linker specs for ppc/musl The change to link libssp_nonshared.a only for musl was to move spec file changes to config/linux.h under a conditional when DEFAULT_LIBC == LIBC_MUSL which worked fine for all but ppc since gcc for ppc provided its own linux.h overrides which are used. This patch duplicates the change in those headers too Cherry-picked from oe-core master 9d39168a6acfa1f289a4448271c0bf9caaea10ec (From OE-Core rev: 7d391a9e566a6ddc2970fc666a45570310bdc780) Signed-off-by: Khem Raj Signed-off-by: Ross Burton Signed-off-by: Martin Jansa Signed-off-by: Richard Purdie --- ...shared-to-link-commandline-for-musl-targe.patch | 55 ++++++++++++++++++++-- 1 file changed, 50 insertions(+), 5 deletions(-) diff --git a/meta/recipes-devtools/gcc/gcc-6.3/0041-Add-ssp_nonshared-to-link-commandline-for-musl-targe.patch b/meta/recipes-devtools/gcc/gcc-6.3/0041-Add-ssp_nonshared-to-link-commandline-for-musl-targe.patch index 310f7aacba..29b7ce72d2 100644 --- a/meta/recipes-devtools/gcc/gcc-6.3/0041-Add-ssp_nonshared-to-link-commandline-for-musl-targe.patch +++ b/meta/recipes-devtools/gcc/gcc-6.3/0041-Add-ssp_nonshared-to-link-commandline-for-musl-targe.patch @@ -1,4 +1,4 @@ -From 75a42d6d0f1f9784327f74882195a5c24843d5a8 Mon Sep 17 00:00:00 2001 +From 210f6b3b82084cc756e02b8bc12f909a43b14ee8 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Tue, 27 Jun 2017 18:10:54 -0700 Subject: [PATCH 40/49] Add ssp_nonshared to link commandline for musl targets @@ -17,18 +17,21 @@ Upstream-Status: Pending Signed-off-by: Khem Raj --- - gcc/config/linux.h | 6 ++++++ - 1 file changed, 6 insertions(+) + gcc/config/linux.h | 7 +++++++ + gcc/config/rs6000/linux.h | 10 ++++++++++ + gcc/config/rs6000/linux64.h | 10 ++++++++++ + 3 files changed, 27 insertions(+) diff --git a/gcc/config/linux.h b/gcc/config/linux.h -index 2e683d0c430..5ff0a2cb2ff 100644 +index 2e683d0c430..1b4df798671 100644 --- a/gcc/config/linux.h +++ b/gcc/config/linux.h -@@ -182,6 +182,12 @@ see the files COPYING3 and COPYING.RUNTIME respectively.
