2016-04-28	ftrace tests: Use gdb_load_shlib result to lookup IPA in info sharedlibrary	Simon Marchi	1	-2/+2
	Some fast tracepoints tests make sure that the in-process agent library is properly loaded, by searching for the library name in "info sharedlibrary". Originally, it would search for the full path. Since patch "Make ftrace tests work with remote targets" [1], the "runtime" location of the IPA, in the standard output directory, is not the same as the original location, in the gdbserver build directory. Therefore, the patch changed the checks: gdb_test "info sharedlibrary" ".${libipa}." "IPA loaded" to gdb_test "info sharedlibrary" ".[file tail ${libipa}]." "IPA loaded" so that only the "libinproctrace.so" part would be searched for. Antoine (in CC) pointed out that I missed some, so I have to update them. In the mean time, I noticed that I missed a few test failures: adding the SONAME to the IPA makes it possible for the test executable to erroneously pick up libinproctrace.so from /usr/lib if the test harness failed to put the libinproctrace.so we want to test in the right place. To mitigate that kind of error in the future, we can use the return value of gdb_load_shlib (the path of the "runtime" version of the library) and use that to search in the output of info sharedlibrary. When testing locally, gdb_load_shlib returns the full normalized path of the destination library, which the test executable should use e.g.: /path/to/gdb/testsuite/outputs/gdb.trace/thetest/libinproctrace.so My testing showed that it was the same path that gdb displayed in info sharedlibrary. If the test executable picks up another libinproctrace.so, the test will fail. When testing remotely, gdb_load_shlib/gdb_remote_download only returns us "libinproctrace.so", so the situation doesn't really change. If there is a rogue libinproctrace.so in /usr/lib on the target and we fail to download ours, it might cover up a test failure. But that situation is probably still better than the original one, where it wasn't possible to test remotely using the IPA at all.

2015-09-21	Add a gdb.trace test for instruction relocation	Pierre Langlois	1	-0/+114
	This test case makes sure that relocating PC relative instructions does not change their behaviors. All PC relative AArch64 instructions are covered. While call and jump (32 bit relative) instructions are covered on x86. The test case creates a static array of function pointers for each supported architecture. Each function in this array tests a specific instruction using inline assembly. They all need to contain a symbol in the form of 'set_point\[0-9\]+' and finish by either calling pass or fail. The number of 'set_pointN' needs to go from 0 to (ARRAY_SIZE - 1). The test will: - look up the number of function pointers in the static array. - set fast tracepoints on each 'set_point\[0-9\]+' symbol, one in each functions from 0 to (ARRAY_SIZE - 1). - run the trace experiment and make sure the pass function is called for every function. gdb/testsuite/ChangeLog: * gdb.arch/insn-reloc.c: New file. * gdb.arch/ftrace-insn-reloc.exp: New file.
