2015-07-31gcc-multilib-config: Adapt mips for mips64 and different gcc versionsRichard Purdie1
The location of some files for mips varies between gcc 4.9 and 5.2. Ensure that we cover both cases (and allow specified files to be optional). Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2015-07-31cross-canadian/gcc: Various mips64 fixesRichard Purdie1
"n32" is a mips64 variant we need to consider when processing the TARGET_OS extensions. Also add the multilib extensions for mips64. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2015-07-31libgcc: Fix symlink handling in cross-arch multilib casesRichard Purdie2
The symlink being generated needs to match both the current arch (e.g. mips or mips64) but also use the underlying TARGET_SYS without multilib extensions to TARGET_VENDOR or extensions to TARGET_OS. The way multilib changes TARGET_VENDOR meant this code did not have a way of removing that change. The method of removing some TARGET_OS suffixes was also not working. By using immediate expansion to run this code, we can run before the multilib code changes it and get the original values. We then use the *current* TARGET_ARCH value in case this does get changed by the multilib since we need to point at the right compiler (32 bit one for 32 bit code).

2015-07-31gcc-multilib-config: Tweak naming of options to match gcc's expectationsRichard Purdie1
gcc itself does not add the '-' of options to its multilib configuration. We should follow its example. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2015-07-31gcc-cross-canadian: Add symlink to real-ld alongside other symlinksRichard Purdie1
In some cases such as cross architecture configurations (using mips-X-linux on mips64-X-linux), gcc can get confused about finding a 'real' version of ld. Adding a symlink to 'real-ld' allowed these configurations to work properly. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2015-07-31gcc: Add patch to handle on target multilibs betterRichard Purdie4
On target multilibs did not work properly since gcc-cross-canadian was only searching a limited number of sysroot directories to find multilib target binaries. This adds an extra search path to ensure those binaries are found and our gcc-cross-canadian works everywhere we need it to, e.g. with mips trilib configurations. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2015-07-31gcc: Add support for nativesdk-gccRichard Purdie8
Being able to build a nativesdk gcc is useful, particularly in cases where the host compiler may be of an incompatible version (or a 32 bit compiler is needed). Sadly, building nativesdk-gcc is not straight forward. We install nativesdk-gcc into a relocatable location and this means that its library locations can change. "Normal" sysroot support doesn't help in this case since the values of paths like "libdir" change, not just base root directory of the system. In order to handle this we do two things: a) Add %r into spec file markup which can be used for injected paths such as SYSTEMLIBS_DIR (see gcc_multilib_setup()). b) Add other paths which need relocation into a .gccrelocprefix section which the relocation code will notice and adjust automatically. This patch adds tweaks to the relocation script to handle the new section too. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2015-07-27gcc-target 5.1: fix for libcc1Robert Yang4
Fixed: * gcc 5 introduces a plugin libcc1.so, which is used by gdb, the target gcc didn't build it in the past because gcc_cv_objdump is null, and the error was: gcc-5.2.0/libcc1/configure: line 14531: -T: command not found This only happens for tar gcc as the code shows: if test x$build = x$host; then export_sym_check="objdump${exeext} -T" elif test x$host = x$target; then export_sym_check="$gcc_cv_objdump -T" else export_sym_check= fi * Install libcc1.so and libcc1plugin.so to $(libexecdir)/gcc/$(target_noncanonical)/$(gcc_version) as lto-plugin did. * Use sed command to fix bad RPATH iussue.

2015-04-30gcc-shared-source: Add PV to PNRichard Purdie2
This means you can have one gcc version for some gcc recipes (e.g. crosssdk/nativesdk) and another gcc version for target code. Also remove the preferred version entry from the default toolchains list since the version issue is now handled automatically. We also need to specifically handle gcc-source in the license handling code since expanding ${PV} in the base class isn't possible. Since gcc-source doesn't generate any packages directly this shouldn't be an issue and whitelisting in this way is easiest (and matches the rest of the toolchain handling).

2015-04-24gcc-4.9: backport from gcc trunk r212178Stefan Müller-Klieser2
When compiling meta-toolchain-qt5 on cortexa8, the compiler throws an internal compiler error: ... qttools-opensource-src-5.3.2/src/linguist/shared/po.cpp: In function 'bool loadPO(Translator&, QIODevice&, ConversionData&)': qttools-opensource-src-5.3.2/src/linguist/shared/po.cpp:717:1: internal compiler error: in add_stores, at var-tracking.c:6000 ... Tracking this down led to https://bugs.linaro.org/show_bug.cgi?id=534 It seems the bug is well know and fixed upstream. So backporting from trunk seems to be the right solution.

2015-01-29arch-mips.inc: Change definition of TRANSLATED_TARGET_ARCHMark Hatle1
[YOCTO #7230] In certain system configurations TRANSLATED_TARGET_ARCH will not expand in the right order for gcc-cross-candian-mips64n32 to be generated properly. This will cause SDKs to fail to generate properly. Changing the global definition of TRANSLATED_TARGET_ARCH always expands the ABIEXTENSION, which causes the OVERRIDES to pick it up as well. This effectively defines a new class of overrides for the 'n32'. The side effect is that we need to duplicate some mips64 overrides, and redefine others that were previously 'n32' or 'mips64' exclusive to have the correct semantics.

2014-12-03gcc: Rework shared workRichard Purdie7
The current implementation of shared work for gcc is at best confusing. It relies on the fetch/unpack/patch tasks having exactly the same stamps and if this gets broken for some reason, its hard to figure out what the problem is. It also leads to complex code in bitbake. The benefits of shared work for gcc are clear but a better approach is needed. This patch adjusts things so that a single new recipe (gcc-source) provides the fetch/unpack/patch/preconfigure tasks, the rest of gcc simply depends on these tasks and have no fetch/unpack/patch tasks of their own. This means we should get the significant benefits (disk usage/performance) of the single source tree but in a way which has less potential for problems and is easier for people to understand. The cost is an extra recipe/some inc files which is probably a good tradeoff. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2014-10-24gcc: poison default sysroot pathRichard Purdie6
Various pieces of the code assume that the --sysroot option gets passed into the compiler tools. By having a "sane" default, we don't always spot when this occurs and this can later show up as breakage in sstate, or in usage of the external toolchain. We've long since talked about poisoning the default such that it will break unless the correct option is specified. This patch does just that. If this patch causes something to fail to build, it most likely means the various compiler flags and commands are not correctly being passed through to the underlying piece of software and that there is a real problem that needs fixing, its not the fault of this patch.

In this case, to use one toolchain with both, we need to ensure the symlinks exist.
