2020-11-02c6x: Remove multilib requirementDan Tejada1-23/+1
Restore tuple config check Add sample configuration Signed-off-by: Dan Tejada <dan.tejada@cantada.com>
2020-10-13Clarify tree layout of local patches directoryBagas Sanjaya1-2/+4
Currently the help for LOCAL_PATCH_DIR did not specify the tree layout of custom patches directory. This commit adds such explanation. For example, the bundled patches for GCC are placed under packages/gcc/<gcc-version>, thus custom (local) GCC patches should be placed under $LOCAL_PATCH_DIR/gcc/<gcc-version>.

2020-09-14config/libc: Extend glibc 2.32 workaround to include sparcChris Packham1-0/+1

2020-09-03glibc: Don't build with -Werror for powerpc64+glibc-2.32Chris Packham1-0/+1
When building powerpc64+glibc-2.32 we see the following error: [ALL ] In file included from ../sysdeps/powerpc/powerpc32/power4/multiarch/wordcopy-ppc32.c:26, [ALL ] from ../sysdeps/powerpc/powerpc64/multiarch/wordcopy-ppc64.c:18: [ALL ] ../string/wordcopy.c: In function '_wordcopy_fwd_aligned': [ERROR] ../string/wordcopy.c:98:26: error: 'a1' may be used uninitialized in this function [-Werror=maybe-uninitialized] [ALL ] 98 | ((op_t *) dstp)[0] = a1; [ALL ] | ~~~~~~~~~~~~~~~~~~~^~~~ [ALL ] In file included from ../sysdeps/powerpc/powerpc64/power4/../../powerpc32/power4/memcopy.h:38, [ALL ] from ../sysdeps/powerpc/powerpc64/power4/memcopy.h:1, [ALL ] from ../string/wordcopy.c:23, [ALL ] from ../sysdeps/powerpc/powerpc32/power4/multiarch/wordcopy-ppc32.c:26, [ALL ] from ../sysdeps/powerpc/powerpc64/multiarch/wordcopy-ppc64.c:18: [ALL ] ../string/wordcopy.c: In function '_wordcopy_fwd_dest_aligned': [ERROR] ../sysdeps/generic/memcopy.h:72:61: error: 'a3' may be used uninitialized in this function [-Werror=maybe-uninitialized] [ALL ] 72 | #define MERGE(w0, sh_1, w1, sh_2) (((w0) << (sh_1)) | ((w1) >> (sh_2))) [ALL ] | ^~ This seems to only trigger for powerpc64. Other architectures build cleanly. For now avoid specifying -Werror for powerpc64+glibc-2.32. Signed-off-by: Chris Packham <judge.packham@gmail.com>
2020-09-01Add picolibc support [v2]Keith Packard2-0/+130
This adds support for using picolibc instead of newlib on embedded systems. Signed-off-by: Keith Packard <keithp@keithp.com> v2: Add check for meson and ninja Sync option default values with current picolibc defaults Remove xtensa sys header file install as those aren't in picolibc

2020-02-26Set --with-cpu-{32,64} for multilib buildsAlexey Neyman4-0/+8
GLIBC 2.31 needs --with-cpu=ultrasparc for both 32/64-bits now, and --with-cpu only sets the CPU model for the "primary" bitness. Signed-off-by: Alexey Neyman <stilor@att.net>

2019-04-05Enable zlib companion lib if building LTOAlexey Neyman1-0/+1
While we may use build machine's library when building a simple cross, we won't have it for the host machine in a canadian build. Until there are separate selectables for the build/host components, just build our own local zlib. Signed-off-by: Alexey Neyman <stilor@att.net>

- Force building make as a companion tool if host make is older than 4.0 (CentOS 7 currently has 3.82) - Disable 2.29 as a choice if host python is older than 3.4 (CentOS 7 has 2.6 unless python from EPEL is installed) - Python2 emits its version information to STDERR.
