gcc-5, aarch64 support for musl

This patchset adds gcc 5.1.0 recipes, additionally fixes gcc configure defaults for cross building, fixes aarch64 multilib case

Accomodate aach64 for musl and let glibc not build for non-glibc libcs

add patch to libart-lgpl to avoid configure time checks for datasizes

Khem Raj (6):
glibc: ignore for musl/uclibc but only for target recipes
gcc: Add 5 recipes
insane: Support aarch64 on musl
gcc-4.9,gcc-5: Use variable SYSTEMLIBS_DIR instead of hardcoding it
for aarch64
gcc-cross: Pass EXTRA_OECONF_GCC_FLOAT to configure
libart-lgpl: Fix cross compiling

we still need nativesdk or native recipes for libc to come from glibc, but only be ignored for target recipes types

Drop backports obviously
additionally drop local patches around parallel compilation since it got reworked upstream

To select set

GCCVERSION = "5.1%"
SDKGCCVERSION = "5.1%"

in local.conf

2.1.4

This helps in configuring the cross compiler to have sane defaults in case of ARM e.g. it will do the right thing for selecting hardfloat ABI when invoked without using TOOLCHAIN_OPTIONS on cmdline.

only when float ABI changes which may be common across a subset of architectures.

although, I think its going to become a severe usability issue. Look
at the archives there are so many issues reported in various forums which end up exactly to this problem, since users expect that once they installed the SDK it works out of box for the default architecture which is not
the case. It just seems wrong build optimization to make it common per arch it if we can’t have user expectations met.

To be honest I haven't seen that many reports of the problem. We do ship an environment file and in that file we have the options gcc needs to work, the sysroot, the other cflags and the float abi. Unless we go back to a setup of hardcoding the cflags into gcc and have a gcc per set of cflags, this isn't going to work since it solves part of the problem but not all of it.

Our other alternative is to wrap gcc with a script (preferred in PATH) which ensures the right cflags are present. I'd obviously prefer not to do that but it is an option if we believe people can't cope with the environment script.

Cheers,

Richard

search for "gnu/stubs-soft.h not found”
and most of the items you will see are OE related.
some issues are quite complex which happen in applications e.g. wrong atomics use

its also how the target libraries are compiled should match the ABI flags for target gcc

Would solve the cross compile scenario but on-device scenario I am not sure

Agreed, the other option is we have gcc pull the right config from the sysroot in question.

On device is a completely different story. That gcc is target specific and *should* have the right flags set. That isn't what the patch in this thread is about though. On target gcc has always been target specific and will remain so.

Cheers,

Richard

FWIW: when we were upgrading from Dylan to Dizzy one MACHINE with hf, we noticed that few recipes weren't respecting CC variable and ended with mixing soft and hard fp which was luckily detected in build time by linker, so easy to fix.

Having at least QA check which will warn user that some compiled binary has different float ABI then enabled in bitbake environment could be useful. But I agree that it's recipe fault if it doesn't respect CC or *FLAGS variables and we should fix it there instead of building gcc-cross twice (if you have 2 arm MACHINEs with different float ABI).

Another option would be mfloat-abi poisoning if possible like we do with default sysroot parameter, so that the usage of default value is detected as soon as possible.

Regards,

Martin 'JaMa' Jansa     jabber: [email protected]

We use standard ISO C data types and get rid of configure guess work which is iffy in cross compiled environment. Cleans up the re-build as well since we were deleting art_config.h without considering if the file is there in first place or not.

FWIW, modern autoconf has working size detection for types in cross builds.

Still can't argue against using modern types being the right thing though. :)

Oh, once this is merged I'll be moving libart_lgpl to meta-oe as nothing in oe-core uses this very old library.
