2020-02-26Set --with-cpu-{32,64} for multilib buildsAlexey Neyman1-0/+5
GLIBC 2.31 needs --with-cpu=ultrasparc for both 32/64-bits now, and --with-cpu only sets the CPU model for the "primary" bitness. Signed-off-by: Alexey Neyman <stilor@att.net>
2018-12-10Add config flags for omitting 'arch' and 'vendor'Alexey Neyman1-0/+15
... parts of the config tuple. While here, remove parts that are setting portions of the target tuple to a value that's already the default. Signed-off-by: Alexey Neyman <stilor@att.net>

2017-09-03Super-H multilib toolchain fixesAlexey Neyman1-4/+34
1. On SuperH, configuring GCC with explicit variant of the CPU (like "sh4") limits the default set of multilibs to just that CPU and requires --with-multilib-list to change. Allow for "unspecified" variant, so that we can defer to GCC to determine the list. 2. Support toolchains with both endiannesses at the same time. 3. Add a SuperH/newlib sample 4. Add more flags processing for uClibc Signed-off-by: Alexey Neyman <stilor@att.net>

2017-07-08Switch gen-kconfig to new frameworkAlexey Neyman1-2/+0
Also: - Move companion_* to comp_* to match the kconfig symbols - Replace bootstrap with former gen-versions.sh - Fold *.in.2 into their respective first parts; this moves common options to the end - if it is undesirable, inclusion of *.in can be moved where *.in.2 used to be (but that will also move version selection after common options). - Retire addToolVersion.sh (may later replace with a more comprehensive script that tries to download the added tarballs, copy the patches and try to apply them, and create a version.desc).

Instead, prepare the files as a part of bootstrap and install them. This avoids rebuilding these files in each working directory; they don't change anyway as they are generated from the same installed source. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-28Remove explicit core passes selection for multilibAlexey Neyman1-1/+0
It is only used if this libc flavor uses a multilib iterator (and not determines the multilibs itself). This class currently includes glibc, uClibc, musl - but they explicitly select CC_CORE_PASSES_NEEDED anyway. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-17Add an option to "demultilib"Alexey Neyman1-0/+23
It turns out buildroot does not currently accept a toolchain where a dynamic linker does not reside in the multi-os-directory. Unfortunately this is how glibc installs itself on AArch64 without any extra tricks. So, provide an option to force everything into /lib or /usr/lib; patch to buildroot will be worked on separately. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-02-06Remove "pre-declaration" of config optionsAlexey Neyman1-35/+0
... these are apparently not needed with the current kconfig and only result in warnings like "SYMBOL changed state" and "reassigning SYMBOL". Perhaps, it was necessary to run kconfig without first generating config.gen? But now all the targets that invoke $(CONF) have `config_files` as a dependency.

2016-08-23multilib: Determine which options may pass through.Alexey Neyman1-0/+4
On some arches (e.g. MIPS) the options like -mabi do not work if specified more than once (see the comment in 100-gcc.sh). Therefore, we need to determine which of the options produced by <arch>.sh can be passed to multilib builds and which must be removed (i.e., which options vary among the multilibs). This presents a chicken-and-egg problem. GCC developers, in their infinite wisdom, do not allow arbitrary multilib specification to be supplied to GCC's configure. Instead, the target (and sometimes some extra options) determine the set of multilibs - which may include different CPUs, different ABIs, different endianness, different FPUs, different floating-point ABIs, ... That is, we don't know which parts vary until we build GCC and ask it. So, the solution implemented here is: - For multilib builds, start with empty CT_ARCH_TARGET_CFLAGS/LDFLAGS. - For multilib builds, require core pass 1. Pass 1 does not build any target binaries, so at that point, our target options have not been used yet. - Provide an API to modify the environment variables for the steps that follow the current one. - As a part of multilib-related housekeeping, determine the variable part of multilibs and filter out these options; pass the rest into CT_TARGET_CFLAGS/LDFLAGS. This still does not handle extra dependencies between GCC options (like -ma implying -mcpu=X -mtune=Y, etc.) but I feel that would complicate matters too much. Let's leave this until there's a compelling case for it. Also, query GCC's sysroot suffix for targets that use it (SuperH, for example) - the default multilib may not work if the command line specifies the default option explicitly (%sysroot_suffix_spec is not aware of multilib defaults).

2015-11-14Allow --with-cpu/--with-tune for !arm.Alexey Neyman1-2/+5
The configure error mentioned in the commits that disable --with-arch/--with-tune when --with-cpu is specified is specific to ARM builds. For other architectures, it makes sense (hey, it even makes sense for ARM - read 'info gcc'! - it is just a shortcoming of ARM build, apparently). Thus, add an arch setting ARCH_EXCLUSIVE_WITH_CPU (currently, set only for ARM) that will trigger current behavior. Permit combinations of --with-arch/cpu/tune for other arches.

2015-06-21avr: add support for AVR 8-bit architectureErico Nunes1-0/+18
This commit adds support for the Atmel AVR 8-bit RISC architecture. This is the first 8-bit architecture to be added to crosstool-ng so the configuration options for 8-bit architectures are added here as well. gcc has had support for AVR for quite a while, at least since the 4.3 series for the currently popular ATmega microcontroler series. The AVR architecture only supports bare-metal toolchains. gcc for the AVR 8-bit architecture, usually referred to as avr-gcc, is commonly used in conjunction with the avr-libc library which provides additional resources for the Atmel AVR 8-bit microcontrollers. avr-gcc can also be found as a supported package in some recent Linux distributions. This commit also closes #66 Signed-off-by: Erico Nunes <nunes.erico@gmail.com>
2015-06-10arch: do not allow specifying both --with-cpu and --with-tuneYann E. MORIN1-0/+1
Similarly to what we've just done to prevent both --with-arch and --with-cpu, we do the same to prevent using both --with-cpu and --with-tune at the same time, since --with-cpu should fully imply the CPU to tune for (and gcc now errors out when both are specified.

2015-06-08arch: do not allow specifying both --with-arch and --with-cpuYann E. MORIN1-0/+1
Normally, a specific CPU fully implies the architecture level. For example, a cortec-a8 is forcibly an armv7, so spwecifying both is redundant, and even dangerous (as incompatible values may be passed). So far, gcc was pretty happy when both were specified at the same time, and some time ago, it started being a warning, and only recently was it turned into a hard error. So, hide the architecture level prompt when a CPU has been specified. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

2013-01-20arch: allow adding a suffix to the arch-part of a tupleYann E. MORIN"1-0/+15
For some architectures, it is legit to have an alternate value in the 'architecture' part of the tuple. For example: armv5te-* armv7a8-* Besides, some packages expect the tuple to reflect the arch variant (eg. openMPI) to detect the variant's capabilities (eg. atomic primitives). This patch adds an option for the user to specify a suffix to be added to the arch-part of the tuple.

2011-10-19arch: add softfp supportYann E. MORIN"1-0/+21
Some architectures support a mixed hard/soft floating point, where the compiler emits hardware floating point instructions, but passes the operands in core (aka integer) registers.

2010-06-08config: add support for a second part of the generated choicesYann E. MORIN"1-0/+2
Some components have configuration options that can depend on generic options, so they should go below those. uClibc for example: - has its own options (wchar...) - uses the generic options (threads...) - if linuxthreads chosen, offers two impls So we need to be able to split the components options in 2, one part that is above the generic options, and one part that ends up below the generic options.
