* Clarify MIPS ABIs supportThomas Petazzoni2012-09-041-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Practically speaking, MIPS has three useful ABIs: * o32 is for 32-bits CPUs, or 64-bit CPUs running only a 32-bit subset of the instruction set. * n32 is for 64-bits CPUs only. It has 32-bits pointers and long integers. * n64 is for 64-bits CPUs only. It has 64-bits pointers and long integers. See http://www.linux-mips.org/wiki/MIPS_ABI_History and http://www.linux-mips.org/wiki/WhatsWrongWithO32N32N64 for more details. So, this commit reworks the Buildroot MIPS support by: * Add separate mips64/mips64el top-level architectures. * Renaming the n32 ABI option to BR2_MIPS_NABI32, for consistency with BR2_MIPS_OABI32. * Renaming the n64 ABI option to BR2_MIPS_NABI64, for consistency with BR2_MIPS_OABI32. * Make the n32 and n64 ABI selections select the BR2_ARCH_IS_64, since those ABIs are valid on 64-bits CPUs only. * Removing the o64 ABI, which is practicaly never used. * Removing the "none" ABI, which really doesn't make sense. * Introduce the mips64 and mips64el architecture names when a 64-bits MIPS ABI is choosen. This will fix build issue like http://autobuild.buildroot.org/results/9b8c5ea86c953a89e85e7b67e9221de41773f652/build-end.log where gmp was confused by the fact of having a 32 bits architecture (detected by the mips- architecture part of the tuple) but 64 bits integer size when compiling. * Adjust the uclibc.mk logic to support the new mips64/mips64el architecture names, and take into account the renaming of the ABI options. This has been build tested by generating Buildroot toolchains and compiling a few packages for MIPS o32, MIPS n32 and MIPS n64. This work is originally based on prior work done by Gustavo Zacarias.

* toolchain-external: do not allow the user to select hard/soft floatThomas Petazzoni2012-08-011-1/+4
| | | | | | | | | | | | | | | | | Commit ba92d6ef68eeb37ba435648fcfbd1dbe13212e6d made hard float the default when Cortex-A8 and Cortex-A9. The problem it was trying to fix is that the newer Linaro toolchains (2012.05 and 2012.06) are hard-float, so the default selection of soft-float enabled on ARM doesn't work for those toolchains. Unfortunately, not selecting soft-float causes problems with the Crosstool-NG backend at the moment. As an intermediate solution, make the soft float option disappear when using external toolchain: the toolchain will decide by itself whether to generate hard float or soft float code.

| | | | | | | | | | Instead of having two separate list of choices for select the target architecture variant for i386 and x86_64, with many CPU choices duplicated (because all modern x86 CPUs can be both used as i386 or x86_64), merge them into a single list. In the x86_64 case, all the x86 CPUs that do not support the 64 bits instruction set are hidden. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

| | | | | | | | | All the defconfig files used by the autobuilders that use pre-installed external toolchains are making the assumption that the default for a custom external toolchain is "pre-installed".

* Make hard-float the default on Cortex-A8 and Cortex-A9Thomas Petazzoni2012-07-221-1/+5
| | | | | | | | | | | | | | Cortex-A8 and Cortex-A9 ARM cores are guaranteed to provide a hardware floating point unit, so there's no reason to default to software floating point for them. More importantly, the newest Linaro toolchains are hard float toolchains, so basically an user choosing those toolchains and leaving the default option of software float would run in compilation issues. So let's make hard float the default for Cortex-A8 and Cortex-A9. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

* toolchain-external: adjust logic to support Linaro 2012.05Thomas Petazzoni2012-07-221-2/+2
| | | | | | | | | | | | | | | | | | | | | The check_glibc function verifies that the C library of the external toolchain is glibc. To do so, it verified that a file matching ld-linux*.so.* or ld.so.* was found in the lib/ directory of the toolchain's sysroot. However, with the Linaro 2012.05 toolchain, the lib/ directory contains two links named ld-linux-armhf.so.3 and ld-linux.so.3, which means that the first ld-linux*.so.* wildcard expression expands to two files, which generates a syntax error for the "test" program. We replace that with a more elaborate find+wc combination to determine whether at least one matching file is present. The check_arm_abi function verifies the ABI of an ARM toolchain. For EABI, it tested that the target name ends with eabi. However, with Linaro 2012.05, the tuple is now arm-linux-gnueabihf (for hard float), so we have to adjust the logic to accept this additional "hf" specification in the tuple.

* | toolchain/crosstool-NG: disable decimal floatsYann E. MORIN2012-05-163-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Decimal floats were introduced circa gcc-4.2 or -4.3, and requires the floating-point environement fenv.h in the C library. The uClibc .config file used by crosstool-NG to build uClibc is the same as used by the internal buildroot mechanism, and explcitly disables fenv support. The quick workaround is to simply disable decimal floats in all crosstool-NG config files. In the long run, it might be better to check this situation, and/or add code and/or options in crosstool-NG to handle this (but it is much more involved, and this workaround is sane).
