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>
2016-11-22Give companion tools some love.Alexey Neyman7-39/+166
Allow selection of make/m4/... version. Support imports of new versions via addToolVersion.sh. Import newest versions of the companion tools. One non-trivial change is the handling of make versions. Existing code was not handling make companion tool as described (see the previous commit). However, since most modern systems have make 4.x, that previous commit made crosstool-ng always build make as a companion tool. This traces back to the commit dd15c93 from 2014. That commit's log message says that actually it was 3.81 which broke the build for certain component (it was originally breaking eglibc, but I noticed it was breaking current glibc on powerpc64), and introduced an option to force using 3.81 by "components that really need it". It looks like in 2.5 years we haven't seen any such components that really need make 3.81, and (given that make has already had a few releases since 3.81) we're unlikely to see them in the future. Hence, the configure check is changed from "exactly 3.81" to "3.81 or newer". In its current form, configure will accept make 3.80+, and will not require make as a companion tool for 3.81+. We might want to bump the latter check to even newer version given the claim from dd15c93. Killed COMP_TOOLS_make_3_81_NEEDED. Anyway, I retained 3.81 just in case; ditto for m4 1.14.3, autoconf 2.65 and automake 1.11.1. Signed-off-by: Alexey Neyman <stilor@att.net>

2016-10-05Restore 1.0.17 and make 1.0.18 experimental.Alexey Neyman1-0/+10
1.0.18 changed the dependencies for the static libraries, notably in libc/Makefile.in. This resulted in packing a lot of unrelated stuff into libc.a, including (sic!) a nested .a library and stuff from other libraries such as libdl. This results in a failure to statically link with thus created libc.a: .../libc.a(libdl.os):(.literal+0x74): undefined reference to `_dl_tlsdesc_return' This was breaking xtensa-*-uclibc sample.

The option for "1.0.14 or later" version of uClibc-ng is not currently used; rename it to "1.0.15 or later" and use it to handle newer uClibc-ng's linuxthreads. m68k happens to be the only sample using linuxthreads.

2016-08-23glibc.sh: cleanupsAlexey Neyman1-10/+0
- 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>
2016-08-23multilib: 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).

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>
2016-06-10musl: 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>
