* gh-109972: Enhance test_gdb (#110026) * Split test_pycfunction.py: add test_cfunction_full.py. Split the function into the following 6 functions. In verbose mode, these "pycfunction" tests now log each tested call. * test_pycfunction_noargs() * test_pycfunction_o() * test_pycfunction_varargs() * test_pycfunction_varargs_keywords() * test_pycfunction_fastcall() * test_pycfunction_fastcall_keywords() * Move get_gdb_repr() to PrettyPrintTests. * Replace DebuggerTests.get_sample_script() with SAMPLE_SCRIPT. * Rename checkout_hook_path to CHECKOUT_HOOK_PATH. * Rename gdb_version to GDB_VERSION_TEXT. * Replace (gdb_major_version, gdb_minor_version) with GDB_VERSION. * run_gdb() uses "backslashreplace" error handler instead of "replace". * Add check_gdb() function to util.py. * Enhance support.check_cflags_pgo(): check also for sysconfig PGO_PROF_USE_FLAG (if available) in compiler flags. * Move some SkipTest checks to test_gdb/__init__.py. * Elaborate why gdb cannot be tested on Windows: gdb doesn't support PDB debug symbol files. (cherry picked from commit757cbd4f29) * gh-104736: Fix test_gdb tests on ppc64le with clang (#109360) Fix test_gdb on Python built with LLVM clang 16 on Linux ppc64le (ex: Fedora 38). Search patterns in gdb "bt" command output to detect when gdb fails to retrieve the traceback. For example, skip a test if "Backtrace stopped: frame did not save the PC" is found. (cherry picked from commit44d9a71ea2) * gh-110166: Fix gdb CFunctionFullTests on ppc64le clang build (#110331) CFunctionFullTests now also runs "bt" command before "py-bt-full", similar to CFunctionTests which also runs "bt" command before "py-bt". So test_gdb can skip the test if patterns like "?? ()" are found in the gdb output. (cherry picked from commit1de9406f91)
