* gnuprumcu: Bump to v0.6.0Dimitar Dimitrov2021-08-221-5/+4
| | | | | | | | | | | | Changes since v0.5.0: * Add spec files for am64x SoCs. * Require Binutils at least version 2.37. * Require pru-gcc to be installed. * Remove linker scripts. Instead set memory sizes from specs. * Activate --gc-sections linker option by default. * The "--host=pru" configure option must be used instead of "--target=pru.

* newlib-nano: Fix nano.spec based on CT_NEWLIB_NANO_INSTALL_IN_TARGETKumar Gala2021-07-301-1/+28
| | | | | | | | | The spec file was missing replacing various libs like libc, libm, etc with their nano equiv when CT_NEWLIB_NANO_INSTALL_IN_TARGET=y. Update the nano.spec file that is generated to rename libc, libm, etc if CT_NEWLIB_NANO_INSTALL_IN_TARGET=y Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

* Fix build of older Glibc using GCC >=10Nik Konyuchenko2021-06-241-0/+4
| | | | | | | | | | | | | 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 Packham2021-06-201-10/+10
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | This commit adds a new config that can be used to specify the target CXXFLAGS specific to the libstdc++ newlib-nano variant.

| * gcc: Allow setting custom target CXXFLAGSStephanos Ioannidis2021-06-071-3/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds two additional arguments (`cxxflags_for_target` and `extra_cxxflags_for_target`) for the gcc backend build function that can be used to specify custom target CXXFLAGS. By default, the target CXXFLAGS is set to the target CFLAGS. When `cxxflags_for_target` is specified however, it overrides that behaviour and allows setting different target CXXFLAGS from the target CFLAGS. The `extra_cxxflags_for_target` argument can be used to specify the extra target CXXFLAGS to be appended to the target CXXFLAGS. This is useful when it is necessary to append CXX-specific flags to the existing CFLAGS to be used as the target CXXFLAGS. A useful application of this is building full and nano versions of libstdc++ with different target CXXFLAGS as necessitated by `nano.specs`. Signed-off-by: Stephanos Ioannidis <root@stephanos.io>
| * gcc: Assume '-O2' by default for building gcc target librariesStephanos Ioannidis2021-06-071-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gcc target libraries (e.g. libstdc++) are currently built without any optimisation flag when `CT_CC_GCC_ENABLE_TARGET_OPTSPACE` is not enabled and default to `-O0` unless user explicitly specifies an optimisation flag. This commit updates the gcc build script to assume `-O2` for building target libraries unless user provides a different optimisation flag. Note also that this is the default behaviour for gcc when C[XX]FLAGS_FOR_TARGET is not overridden. Signed-off-by: Stephanos Ioannidis <root@stephanos.io>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In currently generated top-level "nano.specs" we resolve paths during toolchain building and then use those pre-defined full paths once the toolchain got built.

|/ | | | | | | | | | | | | | | | | | | | | Some really old GDB releases did have gdbserver's configure script w/o execution permissions, so there was a need in the fix. As per Yann most likely it could have been true for GDB versions in between v5.3 & 6.6. Moreover it could have been fixed on re-release of GDB tarballs done in 2011, see [1]. And given we no longer support such old GDB versions in CT-NG (as of today we have 6.8 - 9.2, moreover it's not clear which of 6.8-7.x versions are still being actively used) we'll revert that old hack for now in a hope that it won't hurt anybody. Though if somebody sees that problem again we'll be able to revert this again ;) [1] https://sourceware.org/legacy-ml/gdb/2011-09/msg00002.html Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | If existing board's .specs are used for linking of a user's application, then instead of normally used libs like libc.a & libstdc++.a might be requested their "nano"-suffixed siblings: libc_nano.a, libstdc++_nano etc. That way: ----------------------------->8--------------------------- %rename link_gcc_c_sequence myboard_link_gcc_c_sequence *myboard_libc: %{!specs=nano.specs:-lc} %{specs=nano.specs:-lc_nano} *link_gcc_c_sequence: %(myboard_link_gcc_c_sequence) --start-group %G %(myboard_libc) --end-group ----------------------------->8--------------------------- Our companion newlib-nano libs are all built optimized for size, so we'd like to use them for linking. But given linker will see "-lc_nano -lstdc++_nano" on its command line non-suffixed libs will be ignored. To solve it we create those "_nano"-suffixed libraries as simple symlinks to existing libs..

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since glibc 2.27 glob interface was changed [1] and so "glob" & "glob64" symbols require glibc 2.27+. For us that means if we build Binutils on a machine with glibc 2.27+ produced binaries won't be any longer usable on machines with older glibc. As an example [2]: build on Ubuntu 18.04 (with glibc 2.27) and try to run on CentOS 7.x (with glibc 2.17), you'll see this: ---------------------->8------------------- ldd ld ld: /lib64/libc.so.6: version `GLIBC_2.27' not found (required by ld) ---------------------->8------------------- Now given glob is not really used by Binutils itself (only needed by GDB) and we build Binutils & GDB separately let's make at least Binutils more portable. In theory we may even try to do the same hack for GDB forcing it to use imported glob implementation. But since GDB is now built strictly by C++ compiler we'll get waaay to many incompatibilities due to multiple changes of C++ ABI in between GCC 7.5 of Ubuntu 18.04 and GCC 4.8.5 of CentOS 7.x, so there's no point to even try.
