OpenEmbedded/Yocto Project extensively uses gcc to cross compile in many different and interesting places. On the most part we're very happy, thanks! We do have a small collection of patches and I believe it would be beneficial to share some of them.
I've picked some of the simpler ones and have tried to start that with this series. I did send the first four once already but have reworked the first patch as advised (it became clear we had further related fixes too which I've merged in). It may also be interesting for gcc developers to know that Yocto Project is running the gcc test suite for each of the major architectures we target under qemu (some in system, some in user mode) and collecting test results with a view to trying to ensure we don't regress over time. As time permits, we hope to track down failures and improve the pass rates too. A report from our recent release is here: http://downloads.yoctoproject.org/releases/yocto/yocto-3.4/testreport.txt but is large so I placed some examples here: ========================================================================= qemuppc PTest Result Summary ========================================================================= ------------------------------------------------------------------------- Recipe | Passed | Failed | Skipped ------------------------------------------------------------------------- binutils | 221 | 2 | 13 binutils-gas | 343 | 2 | 3 binutils-ld | 1386 | 7 | 352 gcc-g++-user | 195119 | 37 | 9389 gcc-libatomic-user | 44 | 0 | 5 gcc-libgomp-user | 2788 | 2 | 370 gcc-libitm-user | 46 | 0 | 2 gcc-libstdc++-v3-user | 14152 | 7 | 723 gcc-user | 134355 | 200 | 4104 glibc-user | 3869 | 210 | 76 ------------------------------------------------------------------------- ========================================================================= qemux86 PTest Result Summary ========================================================================= ------------------------------------------------------------------------- Recipe | Passed | Failed | Skipped ------------------------------------------------------------------------- binutils | 230 | 2 | 13 binutils-gas | 1485 | 0 | 1 binutils-ld | 1641 | 7 | 354 gcc | 124619 | 132 | 26160 gcc-g++ | 186472 | 56 | 19103 gcc-libatomic | 22 | 1 | 27 gcc-libgomp | 1427 | 2 | 1671 gcc-libitm | 24 | 1 | 24 gcc-libstdc++-v3 | 9102 | 33 | 5216 glibc | 4230 | 203 | 40 Cheers, Richard Richard Purdie (5): Makefile.in: Ensure build CPP/CPPFLAGS is used for build targets gcc: Fix "argument list too long" from install-plugins gcc: Add --nostdlib++ option gcc/nios2: Define the musl linker gcc: Pass sysroot options to cpp for preprocessed source Makefile.in | 6 ++++++ Makefile.tpl | 6 ++++++ configure | 4 ++++ configure.ac | 4 ++++ gcc/Makefile.in | 2 +- gcc/c-family/c.opt | 4 ++++ gcc/config/nios2/linux.h | 1 + gcc/configure | 2 +- gcc/configure.ac | 2 +- gcc/cp/g++spec.c | 1 + gcc/cp/lang-specs.h | 2 +- gcc/doc/invoke.texi | 8 +++++++- gcc/gcc.c | 3 ++- 13 files changed, 39 insertions(+), 6 deletions(-) -- 2.25.1
