2017-05-25Retire CT_CC_GCC_TARGET_FINALAlexey Neyman1-8/+4
Make this behavior default in case the core gcc backend is used for final compiler (i.e., for baremetal configurations). Not setting this option breaks canadian baremetal configurations, and not setting it makes little sense at all in any baremetal configuration (since in baremetal we don't have any libc to begin with).

2017-03-27Fix up the sysroot issue for sh4 in a different wayAlexey Neyman1-52/+2
(see the comments in the code for details on the issue) Old workaround in 100-gcc.sh stopped working (probably, due to one of GCC version upgrades), so switch to the other approach originally described there: adjust the list of multilibs to not include the default target explicitly.

2017-03-17Add an option to "demultilib"Alexey Neyman1-20/+38
It turns out buildroot does not currently accept a toolchain where a dynamic linker does not reside in the multi-os-directory. Unfortunately this is how glibc installs itself on AArch64 without any extra tricks. So, provide an option to force everything into /lib or /usr/lib; patch to buildroot will be worked on separately.

2017-03-13Create ld.so.confAlexey Neyman1-1/+1
Also a fix for CT_IterateMultilibs: it didn't pass multi_os_dir_gcc, so it only worked if the caller did *not* declare it as a local variable. Signed-off-by: Alexey Neyman <stilor@att.net>

... and then use the right option. See the note in scripts/functions on where we should use ${foo} and where just 'foo'; this boils down to whether we can expect the build tools override to be in effect (e.g. in the actual build scripts) or not (i.e. outside of scripts/build). While running in scripts/functions, or in scripts/crosstool-NG.sh the build tools override directory (.build/tools/bin) may have not been set up (yet, or at all).

2016-11-29Pass FOR_BUILD flags when building the pass-1/2 core GCC.Alexey Neyman1-7/+8
Current build passes {CFLAGS,LDFLAGS}_FOR_HOST - which breaks canadian cross (e.g. tried building for x86_64-unknown-linux-uclibc host). This dates back to the days of yore when CFLAGS were set directly in the do_gcc_core_backend (and that function is used as the final gcc's backend). do_gcc_core_backend is now passed with CFLAGS/LDFLAGS to use, so let the pass-1/pass-2/final-for-build steps pass the appropriate flags.

2016-11-21Partially revert 6f8e89cb5ca061e899bf3feaaf3fecf30d366c3e.Alexey Neyman1-27/+27
The referenced commit replaced 'make' with '${make}' everywhere. This is wrong for at least the utilities that we may build as companion tools (make, libtool): this will always invoke the version detected by configure by supplying the absolute path. In other words, the wrappers in .build/tools/bin are not fallbacks - they are either temporary (in case a respective companion tool is built) or permanent redirectors. This is the reason why the PATH= has .build/*/buildtools/bin at higher precedence than .build/tools/bin; the latter has the versions detected by configure and the former has the versions built as companion tools. Revert the rest of the gang (grep/sed/...) for consistency. After all, we may decide to supply some of them as well (awk, for instance). Signed-off-by: Alexey Neyman <stilor@att.net>

2016-10-07Fine-tune moving gcc libraries to sysroot.Alexey Neyman1-0/+12
1. Check if anything was installed outside sysroot; on some [baremetal only?] configurations GCC doesn't install anything to ${CT_PREFIX_DIR}/${CT_TARGET}/lib. 2. We need to create <sysroot>/lib/<multilib> if it doesn't exist (MUSL only installs in <sysroot>/usr/lib). 3. Do not move the linker scripts; elf2flt expects to find them in gcc's dir, not sysroot.

2016-08-23libc/*.sh: handle combinations of multilib root/dir.Alexey Neyman1-3/+5
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 Neyman1-51/+167
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).

2016-08-23crosstool-NG.sh.in: Don't make lots of symlinks to lib folderRay Donnelly1-31/+43
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').

2016-06-10Enable 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>

2016-01-06gcc: remove CC_GCC_EXTRA_ENV_ARRAYBryan Hundven1-8/+3
I was noticing that $extra_user_env was inconsistently used in 100-gcc.sh. I don't feel comfortable having just any make flag or environment variable passed to make from a config file.
