comment "GCC Options"

prompt "GCC compiler Version"
gcc: rename option for ARC gcc The ARC gcc version is now based on gcc 6.x and no longer gcc 4.8.x, which makes the option BR2_GCC_VERSION_4_8_ARC a bit irrelevant, as is the prompt of this option. This commit therefore renames this option to BR2_GCC_VERSION_ARC, and adjust its prompt as well. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

arch: add OpenRISC architecture support Add support for OpenRISC. See here for more details about OpenRISC http://openrisc.io. All buildroot included upstream binutils versions are supported. Gcc support is not upstream, to be able to enable musl C library support later, we use the branch with musl support. At the moment it is possible to build a musl based toolchain, but bootup in Qemu fails. Gdb is only working to debug bare-metal code, there is no support for gdbserver/gdb on Linux, yet.

We have been having toolchains in the autobuilders with gcc 7.x for a while, so the vast majority of the problems should have already been solved.

package/gcc: introduce BR2_GCC_SUPPORTS_LIBCILKRTS libcilkrts was introduced in gcc 4.9, and removed in gcc 8.x. Therefore, it does not make sense to pass --disable-libcilkrts in gcc 8.x and higher. This commit introduces BR2_GCC_SUPPORTS_LIBCILKRTS that allows the makefile code to know if the selected gcc version supports libcilkrts or not. This new option mainly allows to annotate the fact that libcilkrts exists in gcc [4.9, 7] and that once we have dropped support for those gcc versions, the libcilkrts related logic can be removed.

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.

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>

Enable OpenMP support for the compiler
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.
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.

config BR2_GCC_ENABLE_GRAPHITE
bool "Enable graphite support"
gcc: support grahite only for GCC 5 or above GCC 4.9.x requires an old version of ISL to support graphite, and this old version of ISL is not sufficient to support graphite in modern GCC versions. Since GCC 4.9.x is getting older, and to keep things simple, we stop supporting graphite on old GCC < 5.x. This way, we will be able to bump ISL to a version that is suitable for modern GCC versions. In addition, this allows to drop the dependency on cloog, which was only needed for GCC 4.9.
