2016-08-23Create multilib configurations based on certain *-linux-* samples.Alexey Neyman18-0/+166
Based on the following samples: - x86_64-unknown-linux-gnu (-m64/-m32/-mx32) - powerpc64-unknown-linux-gnu (-m64/-m32) - mipsel-unknown-linux-gnu (-mabi={32,n32,64}) - sh4-unknown-linux-gnu (-m4/-m4a) - x86_64-unknown-linux-uclibc (-m64/-m32) - mips64el-unknown-linux-uclibc (-mabi={32,n32,64}) New samples: - sparc64-multilib-linux-gnu (-m64/-m32) - sh4-multilib-linux-uclibc (-m4/-m4a/-m3) - x86_64-multilib-linux-musl (-m64/-m32) Notably missing is arm-unknown-linux-gnu (aprofile): GLIBC does not compile in one of the variants in its multilib set (-march=armv4t -mthumb) due to missing atomic ops implementation.

'ld' does not search for dependency libraries in multi_os_directory, so if there's both multi_os_directory and multi_root, and there is only one configuration in each multi_root, forgo the multi_os_directory suffix. Needed for sh4-multilib-linux-uclibc. Signed-off-by: Alexey Neyman <stilor@att.net>

2016-08-23Change multilib functions to set the variable.Alexey Neyman7-57/+79
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 Neyman21-149/+96
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.

2016-08-23uclibc: merge startfiles/final into single backend.Alexey Neyman2-162/+111
In preparation for multilib support, use the same "backend" model that is already employed by glibc and musl. Also, the verbosity setting descriptions were swapped. V=2 is actually less verbose than V=1: V=1 prints full commands, while V=2 prints 'CC <file> <defines>'. Signed-off-by: Alexey Neyman <stilor@att.net>

2016-08-23glibc.sh: cleanupsAlexey Neyman2-65/+33
- Dump CT_LIBC_EXTRA_CC_ARGS: instead, treat CT_LIBC_EXTRA_CFLAGS as arguments to CC (or they are not applied to .S, for example). Combine them with multi_flags and CT_TARGET_CFLAGS in proper order. - Analyze thus combined flags to determine --with-fp/--without-fp. Don't need to check CT_ARCH_FLOAT - it is reflected in CT_TARGET_CFLAGS anyway. Check more soft/hard float options defined on different architectures. - Drop checking for endianness flags: they are not reflected in configure arguments in any way, and they're already present in CFLAGS (either via multi_flags or via CT_TARGET_CFLAGS). Besides, CT_ARCH_ENDIAN_OPT was actually called CT_ARCH_ENDIAN_CFLAG, so this was a no-op anyway. Signed-off-by: Alexey Neyman <stilor@att.net>
2016-08-23libc/*.sh: handle combinations of multilib root/dir.Alexey Neyman6-171/+197
Install startfiles for libc variants into the most specific combination (suffixed sysroot, if applicable + suffixed multi-os dir, if applicable). Install headers once in every suffixed sysroot (although it seems that GCC picks up headers from top-level sysroot, GCC manual claims that sysroot suffix affects headers search path). In uClibc, this requires a better sanitization of the directory: it creates symlinks from {sysroot}/usr/lib/{multi_os_dir} to {sysroot}/lib/{multi_os_dir} and to do so, it counts the number of path components in the libdir. This breaks if one of such components is `..' - symlinks contain an extra `../..' then. Since such sanitization had to be implemented anyway, use it in other places to print more sensible directory names. Also, fix the description of configure --host/--target per musl's configure help message (and its actual code). Signed-off-by: Alexey Neyman <stilor@att.net>
2016-08-23multilib: Determine which options may pass through.Alexey Neyman5-55/+224
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).

2016-08-23glibc: Build manuals and locales lastRay Donnelly1-3/+17
Rather then building the manuals and locales for each multilib target, only build the manuals on the last multilib target. If you are not building a multilib toolchain, then the first libc build will be the last. Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>
2016-08-23crosstool-NG.sh.in: Don't make lots of symlinks to lib folderRay Donnelly3-68/+47
For 4 different folders: ${CT_PREFIX_DIR} ${CT_SYSROOT_DIR} ${CT_SYSROOT_DIR}/usr ${CT_PREFIX_DIR}/${CT_TARGET} .. symlinks from 'lib32' and 'lib64' to 'lib' were created. This was untidy and incorrect for multilib (the bitness of the libraries in 'lib32' and 'lib64' will not be the same) We can not know which folders this toolchain configuration will require at this time so let them be created on-demand instead. Changed by Alexey Neyman: original change removed too much; we still need to create the default directories because the os directories are based off them (e.g. `lib/../lib64').

2016-08-23glibc.sh: Use --print-multi-os-directoryAlexey Neyman1-41/+44
GCC makes the distinction between: multilib (-print-multi-lib) and multilib-os (--print-multi-os-directory) as the GCC library and GCC sysroot library paths, respecitively. Use this to build libc into the correct locations, the same applies to the dummy libc.so Changed by Alexey Neyman: restore missing CT_EndStep.

2016-06-10glibc: Use common arch call to get multilib targetsRay Donnelly2-1/+37
The previous patch added the function 'CT_DoMultilibTarget()' to scripts/build/arch/*.sh. This patch calls the common function to (currently) get just the target tuple for the current multilib target. This patch was originally by: Cody P Schafer Changed by Alexey Neyman: first, try `gcc -print-multiarch`. If it is supported, use whatever it reports. Otherwise, fall back to our guesswork. Move "i486" quirk into glibc.sh, as it is specific to glibc (e.g. uclibc will need i386, which is what GCC reports).

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.

2016-06-10Enable multiarch support in pass-1 GCC.Alexey Neyman1-3/+12
By default, it is 'auto' - which means, it is enabled if there are multilibs directories detected in the installation location for libgcc. Thus, it is not detected for pass-1 GCC: the installation location is empty at this point. Signed-off-by: Alexey Neyman <stilor@att.net>
2016-06-10glibc: do not add bogus optionsAlexey Neyman1-2/+2
If a multilib configuration contains an endianness option, the ${endian_extra} is set to, for example, 'mb' (note, no dash!). It is then added to CFLAGS, resulting in bogus flags like 'mb -mb'. But it is not even needed, as ${extra_flags} already contains the very same option! Found by experimenting with multilibs with different endianness on SH, which still didn't work, but that's another story... Signed-off-by: Alexey Neyman <stilor@att.net>
2016-06-10sh: require multilibAlexey Neyman1-0/+1
Now that libc backend installs the libraries into the directory reported by gcc as 'multi-os-directory', sh4 libraries are installed into a '!m4' subdirectory. This directory then confuses GNU ld, which assumes the exclamation mark to be a word separator and attempts to link to '/usr/lib' (a directory). However, if multilib is enabled, the default libraries are installed into the [expected] '/usr/lib/./'. This looks like an artifact of SuperH's unique way of specifying the multilibs to be built in GCC (which may list exclusions, starting with '!'). Signed-off-by: Alexey Neyman <stilor@att.net>
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.

2016-06-10musl: config is broken for !EXPERIMENTALAlexey Neyman1-0/+1
If EXPERIMENTAL is not set, the only choice for version is the set of released versions - currently, 1.1.14. But this only option is disabled because it is also marked EXPERIMENTAL; this leaves no available choices in the configuration. Marking MUSL as experimental: it seems to have header issues which prevent, for example, gdbserver from building. musl copied chunks of ptrace.h code from the kernel into its own headers, which now clash with Linux kernel headers. Manifests at least on SH4 target. Also, musl breaks in powerpc builds: GCC balks at it with "unsupported DEFAULT_LIBC" message. Also, 64-bit powerpc and mips are not supported. So, until someone figures out the dependencies for musl in config/, mark it experimental. Signed-off-by: Alexey Neyman <stilor@att.net>
