Details of changelog [1] Removing bfd/ld patch to enable PE targets, instead use specific emulations via --enable-targets for x86_64 Re-arrange/forward-port patches and upgrade libctf configure to libtool 2.4 patch rpaths are no longer emitted into elfedit/readelf therefore no need of chrpath anymore Instead of pre-generating configure scripts and house them in libtool patch, generate them during configure. This also ensures that we do not patch configure directly but rather the sources which generate it Package newly added libctf library [1] https://lists.gnu.org/archive/html/info-gnu/2020-02/msg00000.html (From OE-Core rev: 82f7d5cfc2ab02f39b69c0f8697d660936422d4a) Signed-off-by: Khem Raj <raj.khem@gmail.com> Cc: Christopher Clark <christopher.clark6@baesystems.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

Subject: [PATCH] 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. When the binaries
|
|
will be relocated, at SDK install time, the interpreter path can be easily
|
|
changed by the relocating script.
|
|
|
|
Upstream-Status: Inappropriate [SDK specific]
