* Rename to allow_hw_breakpoint_testsTom Tromey2023-01-131-3/+1
| | | | | | | | | This changes skip_hw_breakpoint_tests to invert the sense, and renames it to allow_hw_breakpoint_tests. This also converts some tests to use "require" -- I missed this particular check in the first series.
* Update copyright year range in header of all files managed by GDBJoel Brobecker2023-01-011-1/+1
| | | | | | | This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
* Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker2022-01-011-1/+1
| | | | | | | | This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.
* gdb/testsuite: make runto_main not pass no-message to runtoSimon Marchi2021-09-301-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | As follow-up to this discussion: https://sourceware.org/pipermail/gdb-patches/2020-August/171385.html ... make runto_main not pass no-message to runto. This means that if we fail to run to main, for some reason, we'll emit a FAIL. This is the behavior we want the majority of (if not all) the time. Without this, we rely on tests logging a failure if runto_main fails, otherwise. They do so in a very inconsisteny mannet, sometimes using "fail", "unsupported" or "untested". The messages also vary widly. This patch removes all these messages as well. Also, remove a few "fail" where we call runto (and not runto_main). by default (without an explicit no-message argument), runto prints a failure already. In two places, gdb.multi/multi-re-run.exp and gdb.python/py-pp-registration.exp, remove "message" passed to runto. This removes a few PASSes that we don't care about (but FAILs will still be printed if we fail to run to where we want to). This aligns their behavior with the rest of the testsuite.

* Update copyright year range in all GDB files.Joel Brobecker2019-01-011-1/+1
| | | | | | | | | | | | | | | | This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

Test names should start with lowercase unless it starts with the name of a technology, architecture, ISA etc. This first patch addresses cases of test names output explicitly via xfail, kfail, kpass, fail, pass, unsupported, untested and also names set with the pattern "set test" and "set testname". gdb/testsuite/ChangeLog: 2016-12-01 Luis Machado <lgustavo@codesourcery.com> Fix test names

* Remove duplicated code on checking address 0x0 is accessiableYao Qi2014-08-091-7/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I find some gdb.python tests fail on arm-none-eabi target, because the tests assume that memory on address 0x is inaccessible. Some tests (in gdb.base) are aware of this, so do a "x 0" check first. However, the code is copy-n-paste. This patch is to move the "x 0" check to a procedure in lib/gdb.exp, and get needed tests call it. The original code matches pattern "0x0:\[ \t\]*Error accessing memory address 0x0\r\n$gdb_prompt $", but I remove it from the new proc is_address_zero_readable, because GDB doesn't emit such message any more. gdb/testsuite: 2014-08-09 Yao Qi <yao@codesourcery.com> * gdb.base/display.exp: Invoke is_address_zero_readable. * gdb.guile/scm-value.exp (test_value_in_inferior): Likewise. * gdb.python/py-value.exp (test_value_in_inferior): Likewise. * gdb.base/hbreak-unmapped.exp: Return if is_address_zero_readable returns true. * gdb.base/signest.exp: Likewise. * gdb.base/signull.exp: Likewise. * gdb.base/sigbpt.exp: Likewise. * gdb.guile/scm-disasm.exp: Do the test if is_address_zero_readable returns false. * gdb.guile/scm-pretty-print.exp (run_lang_tests): Likewise. * gdb.python/py-arch.exp: Likewise. * gdb.python/py-prettyprint.exp (run_lang_tests): Likewise. * lib/gdb.exp (is_address_zero_readable): New proc.

* Don't suppress errors inserting/removing hardware breakpoints in sharedPedro Alves2014-04-231-0/+72
libraries. As explained in https://sourceware.org/ml/gdb-patches/2008-08/msg00361.html, after a shared library was unloaded, we can no longer insert or remove breakpoints into/from its (no longer present) code segment. That'll fail with memory errors. However, that concern does not apply to hardware breakpoints. By definition, hardware breakpoints are implemented using a mechanism that is not dependent on being able to modify the target's memory. Usually, by setting up CPU debug registers. IOW, we should be able to set hw breakpoints in an unmapped address. We don't seem to have a test that exercises that, so this patch adds one. I noticed the error supression because of a related issue -- the target_insert_hw_breakpoint/target_remove_hw_breakpoint interfaces don't really distinguish "not supported" from "error" return, and so remote.c returns -1 in both cases. This results in hardware breakpoints set in shared libraries silently ending up pending forever even though the target doesn't actually support hw breakpoints. (gdb) set breakpoint always-inserted on (gdb) set remote Z-packet off (gdb) info breakpoints No breakpoints or watchpoints.

Warning: Cannot insert hardware breakpoint 3. Could not insert hardware breakpoints: You may have requested too many hardware breakpoints/watchpoints.

We probably should improve the insert/remove interface to return a different error code for unsupported. But I chose to fix the error supression first, as it's a deeper and wider issue. Tested on x86_64 Fedora 17, native and gdbserver. gdb/ 2014-04-23 Pedro Alves <palves@redhat.com> * breakpoint.c (insert_bp_location, remove_breakpoint_1): If the breakpoint is set in a shared library, only suppress errors for software breakpoints, not hardware breakpoints. gdb/testsuite/ 2014-04-23 Pedro Alves <palves@redhat.com> * gdb.base/hbreak-in-shr-unsupported-shr.c: New file. * gdb.base/hbreak-in-shr-unsupported.c: New file. * gdb.base/hbreak-in-shr-unsupported.exp: New file. * gdb.base/hbreak-unmapped.c: New file. * gdb.base/hbreak-unmapped.exp: New file. * gdb.trace/qtro.exp (gdb_is_target_remote): Move ... * lib/gdb.exp (gdb_is_target_remote): ... here.
