arch/arm: VFP and Thumb1 are not compatible

2015-11-03T22:50:01+00:00

gcc will refuse to build with both --with-mode=thumb and --with-fpu=vfp, with error messages during ./configure, like: checking for suffix of object files... configure: error: in `/home/ymor in/dev/buildroot/O/build/host-gcc-initial-4.9.3/build/arm-buildroot-lin ux-uclibcgnueabihf/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. And config.log informatively contains: sorry, unimplemented: Thumb-1 hard-float VFP ABI This is an error message that comes deep from gcc source files. If gcc says it does not support VFP with Thumb1, then let's disable that combination in our menuconfig. Prefer VFP over Thumb1, i.e. hide Thumb1 when we're not soft-float. Signed-off-by: "Yann E.

arch/arm: use EABIhf by default with VFP

2015-10-25T18:56:20+00:00

Set EABIhf as the default target ABI for the ARM processors that have or may have a VFP unit, since this ABI is the most efficient in that case. Of course, EABI can still be selected manually if needed. [Peter: only default to EABIHF when we are sure the CPU has a VFP] Signed-off-by: Benoît Thébaudeau Signed-off-by: Peter Korsgaard

arch/Config.in.x86: drop trailing dot (.) from x1000 URL

arch/x86: add support for Intel X1000

2015-10-20T08:04:52+00:00

The Intel X1000 is the Pentium class microprocessor that ships with Galileo Gen 1/2. This patch adds changes to arch and toolchain-wrapper to omit the lock prefix for the X1000.

arch: add support for mips32r6 and mips64r6 variants

2015-10-12T19:33:56+00:00

- Add support for mips32r6 and mips64r6 target architecture variants - Disable unsupported gcc versions - Disable unsupported binutils versions - Disable unsupported external toolchains - Disable unsuported C libraries - Add a hook in order to make glibc compile for MIPS R6.

arch/arm: add missing arm1136j-s variant

Identical to arm1136jf-s, except that is doesn't have a vfp unit. Signed-off-by: Peter Korsgaard

ARC: allow selection of MMU page size

2015-07-18T12:07:35+00:00

Modern ARC cores (those sporting MMU of version 3 and 4) allow selection of different page sizes (4, 8 or 16 kB) during ASIC design creation. And it's important to build a toolchain with page size setting that matches hardware. Otherwise user-space applications will fail on execution due to unexpected data layout/alignment etc. [Thomas: slightly improve help text, fix indentation of help text.] Signed-off-by: Alexey Brodkin Cc: Anton Kolesov Cc: Thomas Petazzoni Cc: Arnout Vandecappelle Signed-off-by: Thomas Petazzoni
