* ncurses: Use new v6 ABI by defaultAlexey Brodkin2021-10-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These days old v5 ABI is not that relevant as it used to be back in 2015 when ncurses 6.x was added to CT-NG. And now we see say target "gdb" relying on "libncurses.so.5", while up-to-date Buildroot provides "libncurses.so" & "libncurses.so.6": --------------------------->8------------------------- $ ldd /bin/gdb libncurses.so.5 => not found libstdc++.so.6 => /lib/libstdc++.so.6 (0x20022000) libm.so.6 => /lib/libm.so.6 (0x2017c000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x201ba000) libc.so.6 => /lib/libc.so.6 (0x201c8000) /lib/ld-linux-arc.so.2 (0x20000000) --------------------------->8------------------------- Switching to a default (v6 ABI) by default.

* binutils: Remove obsolete versionsChris Packham2021-09-212-19/+0
| | | | | | | | | | | | | | | The following versions were marked obsolete in crosstool-ng-1.24.0, remove them. - binutils-linaro-2.23.2-2013.10-4 - binutils-linaro-2.24.0-2014.11-2 - binutils-linaro-2.25.0-2015.01-2 - binutils-2.23.2 - binutils-2.24 - binutils-2.25.1 Adjust the milestones now that the old versions have been removed.

* cc/gcc: Add options for zstd usageChris Packham2021-08-291-0/+19
| | | | | | | | | | | | GCC can support using zstd compression for LTO object files. By default GCC's configure will enable this if libzstd is installed on the machine building the toolchain. This may be undesirable if the toolchain is to be used on a different machine. Add an option to control zstd usage and set the default to the same as the current behaviour (i.e. auto). Fixes #1579 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* gdb: Add gdb-10.2Alexey Brodkin2021-08-251-0/+6
| | | | | | | | | | | | | | | | | In GDB 10.x gdbserver was promoted to the top-level folder, see https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=919adfe8409211c726c1d05b47ca59890ee648f1 Which means it is no longer a subfolder in "gdb" and so we have to build gdbserver now exactly in the same way as normal native GDB. One interesting detail is gdbserver doesn't need to deal with target description in .xml so it doesn't depend on libexpat on target, thus we need to move libexpat explicit selection from do_gdb_backend() to its callers when building native [full] gdb as well as cross-gdb for the host.

* Fix build of older Glibc using GCC >=10Nik Konyuchenko2021-06-241-0/+7
| | | | | | | | | | | | | Issue #1535 GCC 10 changed the default to -fno-common, which leads to a linking error in GLibc older than 2.30. This change adds -fcommon cflag for the target GLibc versions <=2.29 and GCC >=10. This change also adds additional cflags for the target GLibc to disable new GCC11 checks that lead to compilation errors. Signed-off-by: Nik Konyuchenko <spaun2002mobile@gmail.com>
* gcc: Make CC_GCC_TM_CLONE_REGISTRY tristateChris Packham2021-06-201-1/+8
| | | | | | | | | | | | | | Explicitly passing --disable-tm-clone-registry causes gcc to create a crtbegin.o with a zero-sized .init_array/.fini_array. This in turn causes ld to complain. Make CC_GCC_TM_CLONE_REGISTRY a tristate so if it's not explicitly enabled we can let ./configure decide.

* Remove m1 from multilibs for GCC11 on SH arch.spaun20022021-05-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC11 somehow has different set of multilibs on SH arch than what GCC10 had. In particular: $ gcc10 -print-multi-lib | sed -r -e 's/@/ -/g;' .; mb; -mb m2; -m2 m2e; -m2e m4; -m4 m4-single; -m4-single m4-single-only; -m4-single-only mb/m2; -mb -m2 mb/m2e; -mb -m2e mb/m4; -mb -m4 mb/m4-single; -mb -m4-single mb/m4-single-only; -mb -m4-single-only mb/m2a; -mb -m2a mb/m2a-single; -mb -m2a-single $ gcc11 -print-multi-lib | sed -r -e 's/@/ -/g;' .; mb; -mb m2; -m2 m2e; -m2e m4; -m4 m4-single; -m4-single m4-single-only; -m4-single-only mb/m1; -mb -m1 mb/m2; -mb -m2 mb/m2e; -mb -m2e mb/m4; -mb -m4 mb/m4-single; -mb -m4-single mb/m4-single-only; -mb -m4-single-only mb/m2a; -mb -m2a mb/m2a-single; -mb -m2a-single mb/m1 fails to build libgcc as libgcc uses opcodes that were not available in SH-1: libgcc/config/sh/lib1funcs.S uses 'bt/s' and 'dt' instructions that, according to https://antime.kapsi.fi/sega/files/h12p0.pdf become available in the SH-2 only. So I removed mb/m1 from the multilibs fog GCC11 and SH arch. Another option would be to try not to build libgcc for this combination of the gcc version and archichecture, but I thought this fix would be more robust.
