gcc: add a BR2_GCC_ENABLE_GRAPHITE option The gcc graphite optimisations such as loop-interchange, blocking and loop-flattening, also known as graphite are an optional feature of gcc that is very well supported since about gcc version 4.5. This patch adds support for graphite for the toolchain as an optional flag for versions 4.8 onwards as an optional flag, that is disabled by default.

ARC: bump tools to 2014.12 release Now when new shiny tools are released by Synopsys we're ready for version update in Buildroot again. More details about arc-2014.12 release are available here: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2014.12 Following patches were removed from GCC since they are a part of release now: * 200-size_type_unsigned_int.patch * 300-ptrdiff_type_int.patch * 400-call-arc_hazard-before-branch-shortening.patch * 401-fix-length-attribute-for-casesi_load-pattern.patch * 402-fix-length-of-instructions-that-are-in-delay-slot-and-needs-to-be-predicated.patch * 403-update-casesi_compact_jump-instruction-length.patch But since arc-2014.12 tools are still based on GCC 4.8 following patches ar still relevant so moving to the new folder to match ARC gcc bump. * 100-libstdcxx-uclibc-c99.patch * 910-gcc-poison-system-directories.patch Binutils are still based on 2.23 so following patch still makes sense: * 600-poison-system-directories.patch Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Anton Kolesov <akolesov@synopsys.com> Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Cc: Peter Korsgaard <peter@korsgaard.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

gcc: use BR2_EXTRA_GCC_CONFIG_OPTIONS in gcc-initial and gcc-intermediate When refactoring the internal toolchain backend logic, the code was changed to pass the custom configure options given through BR2_EXTRA_GCC_CONFIG_OPTIONS only for the gcc final pass, with the idea that we're only interested by user customization for the final compiler. However, the beaglebone_defconfig was passing --with-float=hard --with-fpu=vfpv3-d16 as BR2_EXTRA_GCC_CONFIG_OPTIONS, and since the refactoring, it was causing build failures of the beaglebone_defconfig (with messages saying that Busybox is built to use VFP arguments, but libc/libm are not). This is due to the fact that the gcc intermediate, which is used to build the C library, wasn't built to generate hard float, while the final compiler was generating hard float. So, we get back to the original situation where the options in BR2_EXTRA_GCC_CONFIG_OPTIONS are passed to all of the compiler passes. Of course, the specific case of hard float will be fixed by following patches in this area, but the idea still remains: the three gcc should have the same options, if those options affected the ABI of the generated code.

eglibc: enable support in the Buildroot toolchain backend Using the newly introduced 'eglibc' package, this commit enables the option of building a toolchain using the eglibc C library in the Buildroot toolchain backend. In details, this commit: * Creates a choice to select uClibc or eglibc in the Buildroot toolchain backend (in toolchain/toolchain-buildroot/Config.in), and removes the fact that the Buildroot toolchain backend forcefully enables uClibc (toolchain/Config.in). * Creates a BUILDROOT_LIBC variables, which points to the package implementing the C library (i.e either 'uclibc' or 'eglibc'). * Modifies the gcc-final and gcc-intermediate makefiles to use the BUILDROOT_LIBC variable instead of hardcoding the use of uclibc. * Ensures that TLS support is always enabled when building eglibc.

toolchain: add support for glibc The support for eglibc 2.17 was added to the internal toolchain backend for 2013.08. This commit now adds glibc 2.18 support to the internal toolchain backend. Since the building procedure is very similar to the one of eglibc, we have renamed the 'eglibc' package to 'glibc', and made it capable of handling either glibc or eglibc.

toolchain: add link-time-optimization support Add a new option BR2_GCC_ENABLE_LTO that builds gcc and binutils with LTO support. Individual packages still have to enable LTO explicitly by passing '-flto' to GCC, which passes it on to the linker. This option does not add that flag globally. Some packages detect if the compiler supports LTO and enable the flag if it does. To support LTO, ar and ranlib must be called with an argument which triggers the usage of the LTO plugin. Since GCC doesn't call these tools itself, it instead provides wrappers for ar and ranlib that pass the LTO arguments. This way existing Makefiles don't need to be changed for LTO support. However, these wrappers are called <tuple>-gcc-ar which matches the pattern to link to the buildroot wrapper in the external toolchain logic. So the external toolchain logic is updated to provide the correct symlink. [Thomas: - Add a separate BR2_BINUTILS_ENABLE_LTO option to enable LTO support in binutils. This is a blind option, selected by BR2_GCC_ENABLE_LTO. It just avoids having binutils.mk poke directly into gcc Config.in options. - Remove the check on the AVR32 special gcc version, which we don't support anymore. - Adapt the help text of the LTO Config.in option to no longer mention "Since version 4.5", since we only support gcc >= 4.5 in Buildroot anyway. - Fix typo in toolchain-external.mk comment.] Signed-off-by: Peter Kümmel <syntheticpp@gmx.net> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

gcc: provide option to enable mudflap support The mudflap library is only useful if one uses the -fmudflap gcc option to do more checks on pointers/arrays. This commit adds an option to enable/disable mudflap support at the gcc level. By default, it is disabled, which saves a little bit of build time compared to the default of gcc which consists in enabling mudflap support. Since mudflap is now disabled by default, and ensured to never be enabled on platforms where it is not available, some gcc.mk code that was used to disable mudflap in problematic configurations can be removed. Whether -fmudflap is used when building is left to the user.

libmudflap is a gcc library used for the mudflap pointer
debugging functionality. It is only needed if you intend to
use the -fmudflap gcc flag.
See http://gcc.gnu.org/wiki/Mudflap_Pointer_Debugging and
the help of the gcc -fmudflap option for more details.
If you're unsure, leave this option disabled.
