gcc-runtime: Move gdb pretty printer file to auto-load location

2024-02-09T13:45:02+00:00

When debugging a C++ program on target using libcstdc++, gdb does not find the pretty printer python support, this is because the init file is installed into /usr/lib which is excluded from gdb's default list of directories to load config's from, where as defaults to load from datadir is still on, it therefore does not load this file warning: File "/usr/lib/libstdc++.so.6.0.33-gdb.py" auto-loading has been declined by your `auto-load safe-path' set to "$debugdir:$datadir/auto-load". This leaves the libstdc++ pretty-printers disabled even though added via IMAGE_INSTALL += "gcc-runtime-dbg" Comment on adding missing runtime dependency on datetime python module for the pretty printer to work/load successfully. Once the pretty-printer gdb file is moved out of libdir, it may become empty therefore delete it if its empty.

gcc: Update status of CVE-2023-4039

2024-01-26T16:06:29+00:00

This is fixed via a patch added in gcc-13.2.inc already, but still reported e.g. for libgcc as it is not defining an own source but use the shared gcc-source.

gcc-runtime: remove bashism

2023-09-03T09:34:20+00:00

Debian 12 no longer supports replacing dash with bash as default shell. Therefore to achieve compatibility with Debian 12, all bashisms need to be removed. Shell comparison via == gives an error with dash and thus the condition is always false.

gcc: Add patch to improve testsuite failures, particularly mips

2023-08-15T07:15:25+00:00

Disable loongson-mmi runtine, qemu doesn't appear to fully support them even if some of the instruction decoding is there. Also disable MSA mips runtime extensions. For some reason qemu appears to accept the test code when it shouldn't. Our selected MIPS cpu for QEMU doesn't support them. MIPS is unusual in the gcc testsuite as it uses EFFECTIVE_TARGETS and loops multiple times through the vector testsuite. In the case of the two above, we can compile/link them but not run them. Even with the runtime disabled, if the code marks it as a runtime test, it will elevate itself to that. Setting the default target to compile therefore isn't enough. Therefore add code to downgrade runtime tests to link tests if the hardware support isn't there to run them. This avoids thousands of test failures. To do this we have to hook downgrade code into the main test runner. Enable that downgrading for other cases where hardware to run vector extensions is unavailable to remove test failures on other architectures too. Also, for gcc.target tests, add checks on wheter loongson or msa code can be run before trying that, allowing downgrading of tests there to work too. Parts of the patch may be able to be split off and acceptable to upstream with discussion. Need to investigate why qemu-user passes the 'bad' instructions'. For now, this should at least remove hundreds of test failures and improve test failures on non-mips too now a root cause of some was identified.
