2016-07-19samples: Add powerpc64 little-endian toolchain sampleVaibhav Jain2-0/+16
This change adds a powerpc64le-unknown-linux-gnu sample that can be used to quickly create a little-endian tool-chain for powerpc64 architecture. This sample is based on the earlier work done by "Yann E. MORIN" to add support for powerpc64 tool chain and implementing the power64-unknown-linux-gnu sample. The existing sample however generates a big-endian tool chain by default. Signed-off-by: Vaibhav Jain <vaibhav@linux.vnet.ibm.com>

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. See the pending patch: https://patchwork.ozlabs.org/patch/409424/ 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>

2016-04-02Mark x86_64-w64-mingw32,x86_64-pc-linux-gnu broken.Alexey Neyman2-2/+0
I couldn't get this sample to build. I tried rolling ct-ng back to 1.22 and back to the commit that introduced it, to no avail. Not sure if it ever built on my machine. The first problem is the failure to build binutils/gold because of the missing <pthread.h> in mingw. However, even if CT_BINUTILS_GOLD_THREADS option is unset, the build dies in configure of the pass-1 of the core CC. The config.log states that it failed to link with libmpfr.a, which has a lot of undefined references to symbols like '__imp___iob_func'. Googling shows that these symbols are some dark Cygwin/MinGW magic and I do not have the knowledge of these arcana. Let some other MinGWizard fix it another day.

2016-04-02Unbreak static cross-gdb.Alexey Neyman2-5/+16
GDB's configure mishandles the libexpat.{so,a} libraries when it is given -static in CFLAGS AND --with-libexpat-prefix in configure's args: it checks for <prefix>/lib/libexpat.so and finding that, attempts to link it as `gcc -static .. conftest.c <prefix>/lib/libexpat.so`; this obviously fails (.so cannot be statically linked), so configure assumes libexpat is unusable. Thus, --with-libexpat-prefix is dangerous and should be avoided; instead, configure should find the libraries via the supplied CC/LD definitions.
2016-04-02Unbreak *-uclibc with native GDB.Alexey Neyman1-0/+12
Currently, native GDB 7.11 fails to build with uClibc-ng due to undefined reference to _obstack_free. On IRC [http://crosstool-ng.osuosl.org/download/ibot-logs/2016-02-28.html], it has been suggested to disable obstack in uClibc configuration. I think it is a workaround rather than a fix: if another library/app needs obstack, this leaves no viable configuration. IMO, if uClibc seeks to mimic the glibc API, it should also provide _obstack_free call (an alias for which it already has, even though commented out). Signed-off-by: Alexey Neyman <stilor@att.net>
2016-04-02Unbreak powerpc-unknown-linux-uclibc.Alexey Neyman2-0/+13
There is invalid assembly in dmalloc for PowerPC. The issue is that 'stw' expects a memory operand, and =g constraint allows both registers and memory. Newer GCC tends to choose register even at -O0, resulting in invalid assembly. Instead, force a register constraint in 'mflr' and let GCC decide if it wants to store it into memory at all. Reported this upstream. Signed-off-by: Alexey Neyman <stilor@att.net>
