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>
2016-06-10arch/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.

2016-04-02Work-around another quirk in GDB configure.Alexey Neyman1-4/+11
Previous fix for cross-gdb broke powerpc-unknown_nofpu-linux-gnu which uses an old GDB (6.8a). That GDB's configure chokes on $CC values with multiple consecutive spaces; see the comment in 300-gdb.sh. Signed-off-by: Alexey Neyman <stilor@att.net>

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.

2016-03-01musl-libc: Rewrite musl.sh build scriptBryan Hundven1-50/+67
This commit moves the do_libc_configure function to do_libc_backend and switches do_libc_start_files and do_libc_final to call do_libc_backend. The major reason for the rewrite is that musl => 1.1.13 has had it's own build system rewritten and can now build out-of-tree. Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>

2016-01-03libiconv: configure with --disable-nlsRay Donnelly1-0/+1
On Windows a build failure can be triggered during the build of the static iconv if a dynamic iconv is already present: There's a circular dependency between libiconv and gettext which (on a system with a dynamic gettext (and thus iconv) installed in the system prefix) causes a failure to build iconv.exe statically if it is built with nls .. .. Which needs gettext .. which depends on libiconv .. so libtool finds a dynamically linked libgettext.la .. and therefore presents ld with the dll import library libiconv.dll.a when linking iconv.exe .. as well as the static libiconv.a that it has just built! .. leading to multiply defined symbols from iconv. Therefore, we build it without nls. If it later turns out that we need it to be built with nls, then I will have to build it in two passes (common practice when bootstrapping GNU/Linux distros, MSYS2 and probably Cygwin and Homebrew).

2016-01-03expat: Tidy up and correct configure flagsRay Donnelly1-9/+24
Build shared builds for host unless CT_STATIC_TOOLCHAIN. In all other situations, build statically, as before. It is necessary that the static/shared-ness of expat matches that of gettext on Cygwin/MinGW-w64 as they can't be linked together if they don't match, so we follow the same logic.
