* crossdev: disable USE=hardened by default on bare-metalSergei Trofimovich2019-06-081-0/+1
| | | | | | | | | | | | | USE=hardened enables more stack-check options by default At least on arm-none-eabi that causes build failure: gcc-8.3.0/libstdc++-v3/libsupc++/array_type_info.cc:30:2: sorry, unimplemented: -fstack-check=specific for Thumb-1 {} ^ Reported-by: Bertrand Jacquin Bug: https://bugs.gentoo.org/687598 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

* crossdev: don't enable USE=pie by default on any bare-metal targetsSergei Trofimovich2018-09-181-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately embedded world has a long way to go to adopt --enable-default-pie as a first class citizen. Note: --enable-default-pie enabled two things: - PIC-friendly code generation (-fPIE) - PIE executables (-pie) Normally one would expect firmware to pass compiler modes explicitly to gcc: -fPIC (or -mauto-pic, -fno-PIC), -ffreestanding, -nostdlib. Unfortunately upstreams are frequently reluctant to explicitly specify new moving parts available in gcc (in this case -no-pie) and expect gcc to behave as it used to in the world before --enable-default-pie. Unfortunate but not entirely unreasonable. Disable --enable-default-pie until user explicitly requests USE=pie.

* crossdev: unconditionally create /usr/${CTARGET}/{lib,usr/lib}Sergei Trofimovich2018-04-101-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Copying note as-is here: ``` Create directories usually created by sys-apps/baselayout Why we do that at all: For multilib-aware targets (ppc64, s390x, sparc64, x86_64) Gentoo normally uses libdir=lib64. For crossdev it means /lib and /usr/lib does not get created at all but gcc relies on their presence by refering to =/lib64 as =/usr/lib/../lib64 when builds itself (see https://bugs.gentoo.org/652724) Thus we create non-symlinked layout early. ``` Before the change 'crossdev -t powerpc64le-foo-linux-gnu' failed at gcc-stage2 as: ``` ... \ -shared -nodefaultlibs -Wl,--soname=libgcc_s.so.1 \ -o ./libgcc_s.so.1.tmp \ ... \ /usr/libexec/gcc/powerpc64le-foo-linux-gnu/ld: cannot find crti.o: No such file or directory access("/usr/powerpc64le-foo-linux-gnu/usr/lib/../lib64/crti.o", R_OK) = -1 ENOENT (No such file or directory) ``` The change adds empty directory '/usr/powerpc64le-foo-linux-gnu/usr/lib' to make ld probing finally find 'crti.o' in $SYSROOT.

* crossdev: revert ldscripts hackSergei Trofimovich2018-04-071-12/+0
| | | | | | | | | | | | | | | Commit 03640757f2af1471324fc3e305f899f377d6409d ("add one more avr-specific hack") added ${EPREFIX}/usr/${CTARGET}/lib/ldscripts symlink for avr targets. The bug was not avr-specific but manifested only on avr ecause it's one of rare targets that don't embed default inker scripts intofinal ld executable. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=b023986de7d466d361798bae98f45f8ba7a42e8a fixed search path in binutils ebuild and we are safe to revert this change.

| | | | | | | | | | | | | | | | | | | This is a multi-part message in MIME format. I just noticed a typo in the commit message. Please commit this patch instead. From 0d0b4653e44f807802ef1fa9647c7395d6625609 Mon Sep 17 00:00:00 2001 From: Dennis Schridde <devurandom@users.noreply.github.com> Date: Wed, 3 Jan 2018 23:41:53 +0100 Subject: [PATCH] Fix parse_repo_config with regards to repository priority Before this patch, the repository config would be inserted into a more or less place for the respective priority, resulting in a non-contiguous array, which would no longer be fully enumerated by an awk for loop. Hence the config of repositories with the same priority would be omitted for all but the first few entries. Signed-off-by: Dennis Schridde <devurandom@gmx.net>
