From f809d27e292c7c87083ca17f06d34dd504dfd1f5 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Thu, 20 Aug 2020 01:01:13 -0700 Subject: binutils: Let crosssdk gold linker generate 4096 btyes long .interp section When gold is used as default linker in crosssdk e.g. when building SDK binaries with LTO, the binaries do not have large enough .interp section size and SDK relocation fails for those nativesdk binaries and libraries which used gold for linking. This patch extends the .interp relaxation fix to gold (From OE-Core rev: f856b5f38263251bc48af8ba0da3385c09663d38) Signed-off-by: Khem Raj Signed-off-by: Richard Purdie --- ...nutils-crosssdk-Generate-relocatable-SDKs.patch | 26 +++++++++++++++++----- 1 file changed, 21 insertions(+), 5 deletions(-) (limited to 'meta') diff --git a/meta/recipes-devtools/binutils/binutils/0001-binutils-crosssdk-Generate-relocatable-SDKs.patch b/meta/recipes-devtools/binutils/binutils/0001-binutils-crosssdk-Generate-relocatable-SDKs.patch index 0e62d47616..4c1d11291b 100644 --- a/meta/recipes-devtools/binutils/binutils/0001-binutils-crosssdk-Generate-relocatable-SDKs.patch +++ b/meta/recipes-devtools/binutils/binutils/0001-binutils-crosssdk-Generate-relocatable-SDKs.patch @@ -1,22 +1,38 @@ -From b8d182865081d17549fb9a4b9bc3062b526caf65 Mon Sep 17 00:00:00 2001 +From a0b23b160d6cfa7be4437c6e623633d76395f2ad Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Mon, 2 Mar 2015 01:58:54 +0000 -Subject: [PATCH 01/17] binutils-crosssdk: Generate relocatable SDKs +Subject: [PATCH 01/16] binutils-crosssdk: Generate relocatable SDKs This patch will modify the ELF linker scripts so that the crosssdk linker will generate binaries with a 4096 bytes PT_INTERP section.
