2018-12-04Warn if architecture is empty on x86/32bitAlexey Neyman1-1/+5

2018-12-01Add moxiebox as a choice for libcAlexey Neyman2-1/+12
This required some rework of the libc selection, as moxiebox is a layer on top of another libc - newlib. Also, moxiebox'es host VM (`sandbox`) needs a libcrypto on the host. We will not have it if we're cross-compiling a canadian cross. Fortunately, all moxiebox needs from libcrypto is SHA256, and it already includes a standalone implementation of SHA256 in its runtime. Provide a little wrapper that allows moxiebox use that implementation for the host binary, too. Also, automate collecting/printing the list of all packages in a given category (e.g. LIBC or COMP_TOOLS), generate a list of all Kconfig symbols for a given category.

2018-05-21ARC: Disable CONFIG_ARC_HAS_ATOMICS in uClibc if building without -matomicsAlexey Brodkin1-1/+1
In case we build for ARC core which has no support of atomic ops among other things we need to configure libc to use Linux kernel helper to emulate HS atomic ops. This is done with disabling of CONFIG_ARC_HAS_ATOMICS in uClibc. Currently we __remove__ this option from .config but this makes no sense as its default state is "y" so we need to explicitly disable it instead. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

2017-09-03Use the new SuperH fixes in the two multilib samplesAlexey Neyman2-6/+107
- Glibc configure args and tuple need adjustment on SuperH - Only allow "both endian" and "with CPU" for unspecified arch variant. May reconsider endianness (was breaking things before adjusting glibc tuple) - Retire non-multilib sample, it should be a subset of the multilib one now. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-09-03Super-H multilib toolchain fixesAlexey Neyman2-30/+38
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>

2016-11-22xtensa: fix endianness supportMax Filippov1-0/+2
To build uClibc correctly we need correct endianness selected in the crosstool-NG. Xtensa cores may be little- or big-endian, but this property is static. The toolchain knows the core endianness and doesn't need options to select it. Enable ARCH_SUPPORTS_BOTH_ENDIAN and select LE by default. Specify empty CT_ARCH_ENDIAN_CFLAG so that -m{big,little}-endian don't get added to the TARGET_CFLAGS, as it's not supported by gcc. Specify empty CT_ARCH_ENDIAN_LDFLAG so that -EB/-EL don't get added to the TARGET_LDFLAGS as they are ignored. Select big-endian in the example xtensa-unknown-linux-uclibc configuration. This fixes uClibc toolchain build for little-endian cores. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

Rather than echo-ing the new value, set the value into the variable with the name passed as an argument (similar to CT_SanitizeVarDir). This allows to use CT_DoLog in these functions. Signed-off-by: Alexey Neyman <stilor@att.net>
2016-08-23libc/*.sh: Deprecate libc_check_config step.Alexey Neyman10-71/+59
This step was only used in uClibc. However, with upcoming multilib, the config management will have to be done for each variant differently, anyway. uClibc was the only user of libc_check_config step, as well as CT_CONFIG_DIR directory. Retire these. Two other clean-ups in uClibc.sh: - KERNEL_HEADERS check seems to be bogus, this config option is not present even in 0.9.30 - which is not supported already. - SHARED_LIB_LOADER_PREFIX was renamed to MULTILIB_DIR in 0.9.31, according to ChangeLog - and MULTILIB_DIR is passed from command line instead.

2016-06-10 arch/all: Add common function to return multilib targetAlexey Neyman10-0/+181
This code was abstracted out of Cody P Schafer's multilib patch. It doesn't seem right having architecture dependent code in a specific libc implementation script. So this patch breaks it out into scripts/build/arch/<arch>.sh in a function: multilib_target_to_build="$(CT_DoArchMultilibTarget 'multi_flags' 'target-in')" Note that this function gets called on each multilib variant with different sets of compiler flags supplied in 'multi_flags'. The caller will first filter the flags so that there is no conflicting flags (e.g., no '-m32 -m64') supplied. Changed by Alexey Neyman: - make option analysis check specific option rather than match global options string as a whole. Moreover, old code did not handle multiple options in the same multilib, e.g. '-m64 -mlittle'. - fixed substitutions in powerpc.sh (*le variants did not match the pattern in the shell parameter expansion) - make s390.sh actually apply the flags it gathered from the options. - straighten the spaghetti in x86.sh by setting two flags, arch & abi. Also, do not depend on "gnu" being the last part - we can have '*-uclibcx32', for example.

2016-06-10arch/sparc: better default CPU when targetting LinuxAlexey Neyman1-0/+13
By default, sparc64-*-linux is configured with -mcpu=v9. However, according to https://sourceware.org/ml/libc-alpha/2005-12/msg00027.html: "There is no Linux sparc64 port that runs on non-UltraSPARC-I+ ISA CPUs." v9 is such a "non-UltraSPARC-I+ ISA CPU", so it makes no sense to default to v9 when targetting Linux. Change the default to ultrasparc, even though it can suboptimally schedule instructions for newer SPARC CPUs.

2015-11-13xtensa: add support for the configurable Xtensa architecture.Chris Zankel1-0/+78
The Xtensa processor architecture is a configurable, extensible, and synthesizable 32-bit RISC processor core. Processor and SOC vendors can select from various processor options and even create customized instructions in addition to a base ISA to tailor the processor for a particular application. Because of the configurability, the build process requires one additional step for gcc, binutils, and gdb to update the default configuration. These configurations are packed into an 'overlay' tar image, and are simply untarred on top of the default configuration during the build. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2015-11-10blackfin: Remove blackfin supportBryan Hundven1-14/+0
This commit removes blackfin support. I'm open to re-adding blackfin after crosstool-1.23.0 is released, but it is currently too difficult to port forward to newer versions of gcc and uclibc. Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>
2015-10-31gcc: Support only the latest branch releases of gccBryan Hundven1-13/+0
This change, as per #222, reduces the number of supported releases of gcc to the latest branch releases. I noticed while doing this work that gcc-4.5.4 was never added, so I moved patches for gcc-4.5.3 to 4.5.4 and updated the bfin-unknown-linux-uclibc example. Also, 120-siginfo.patch was fixed upstream in the 4.5.4 release, so this patch is omitted. I also bumped the avr sample to 4.9.3 from 4.9.2. With the addition of gcc-5.x, the gcc release team now releases the major.minor.0 versions, while updates to the branch are available in svn/git. We'll address that when we get to issue #219. This change just removes CC_GCC_5_1 and moves CC_GCC_5_2 to CC_GCC_5, and removes CC_GCC_5_1_or_later and moves CC_GCC_5_2_or_later to CC_GCC_5_or_later. This is the first of two part changes, as mentioned in #222. This change is slated for release in 1.22.0. The next change will be slated for 1.23.0, and will limit gcc versions to what is on https://gcc.gnu.org under "Release Series and Status", which is currently 4.9.3 and 5.2.0, although I will also support the previous supported version. In this example that would be 4.8.5. Last, but not least, this change also retires AVR32 support. Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>
2015-06-21avr: add support for AVR 8-bit architectureErico Nunes1-0/+5
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.

Technically, I don't forbid powerpcle support either, but I'm not sure that there is any library/compiler support for that at the moment (though the hw technically makes it possible). powerpc64le needs glibc 2.19 and gcc 4.9. I haven't looked into the support tools, but at least gdb 7.5 is too old (7.7.1 definitely has support). Also make powerpc64 non-experimental. It's practically old at this point.
