2020-05-14gdb/infrun: enable/disable thread events of all targets in stop_all_threadsTankut Baris Aktemur5-7/+32
In stop_all_threads, the thread events of the current top target are enabled at the beginning of the function and then disabled at the end (at scope exit time). Because there may be multiple targets whose thread lists will be updated and whose threads are stopped, enable/disable thread events for all targets. This update caused a change in the annotations. In particular, a "frames-invalid" annotation is printed one more time due to switching the current inferior. Hence, gdb.base/annota1.exp and gdb.cp/annota2.exp tests are also updated. Regression-tested on X86_64 Linux using the default board file and the native-extended-gdbserver board file. gdb/ChangeLog: 2020-05-14 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * infrun.c (stop_all_threads): Enable/disable thread events of all targets. Move a debug message denoting the end of the function into the SCOPED_EXIT block. gdb/testsuite/ChangeLog: 2020-05-14 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * gdb.base/annota1.exp: Update the expected output. * gdb.cp/annota2.exp: Ditto.
2020-05-14gdb: introduce 'all_non_exited_process_targets' and 'switch_to_target_no_thread'Tankut Baris Aktemur3-0/+43
Introduce two new convenience functions: 1. all_non_exited_process_targets: returns a collection of all process stratum targets that have non-exited inferiors on them. Useful for iterating targets. 2. switch_to_target_no_thread: switch the context to the first inferior of the given target, and to no selected thread. gdb/ChangeLog: 2020-05-14 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * process-stratum-target.h: Include <set>.

2020-05-14gdb/infrun: extract out a code piece into 'mark_non_executing_threads' functionTankut Baris Aktemur2-35/+48
This is a refactoring. The extracted function is placed deliberately before 'stop_all_threads' because the function will be re-used there in a subsequent patch for handling an exit status kind received from a thread that GDB attempted to stop. gdb/ChangeLog: 2020-05-14 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * infrun.c (handle_inferior_event): Extract out a piece of code into...

2020-05-14gdb/infrun: move a 'regcache_read_pc' call down to first useTankut Baris Aktemur2-1/+7
In infrun.c's resume_1 function, move the definition of the local variable PC down to its first use. This is useful if the thread we want to resume is already gone with a pending exit event, because we avoid the error we would see otherwise when trying to read the PC. gdb/ChangeLog: 2020-05-14 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * infrun.c (resume_1): Move a 'regcache_read_pc' call down to first use.
2020-05-14gdb: protect some 'regcache_read_pc' callsTankut Baris Aktemur5-3/+41
It possible that a thread whose PC we attempt to read is already dead. In this case, 'regcache_read_pc' errors out. This impacts the "proceed" execution flow, where GDB quits early before having a chance to check if there exists a pending event. To remedy, keep going with a 0 value for the PC if 'regcache_read_pc' fails. Because the value of PC before resuming a thread is mostly used for storing and checking the next time the thread stops, this tolerance is expected to be harmless for a dead thread/process. gdb/ChangeLog: 2020-05-14 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * regcache.c (regcache_read_pc_protected): New function implementation that returns 0 if the PC cannot read via 'regcache_read_pc'. * infrun.c (proceed): Call 'regcache_read_pc_protected' instead of 'regcache_read_pc'. (keep_going_pass_signal): Ditto. gdbsupport/ChangeLog: 2020-05-14 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * common-regcache.h (regcache_read_pc_protected): New function declaration.

2020-05-12gdb/testsuite: Disable path and duplicate checks when parallel testingAndrew Burgess2-0/+25
This commit disables the recently added checking for paths in test names, and for duplicate test names, when the gdb tests are run in parallel. When running the gdb tests in parallel the extra result count lines produced cause the dg-extract-results scripts to exit with an error. The patches for the dg-extract-results scripts have been posted to the gcc-patches mailing list here: https://gcc.gnu.org/pipermail/gcc-patches/2020-May/545562.html Once they are merged there then these changes can be merged over to binutils-gdb, and this commit can be reverted. gdb/testsuite/ChangeLog: * lib/check-test-names.exp: Disable when testing is being run in parallel.

Splits ELF related symbols into a separate jit-elf-util.h header and enhances it with a few more. Intention is to make adding new JIT tests possible without repeating most of the common boilerplate.

2020-05-11gdb/testsuite: Detect and warn about duplicate test namesAndrew Burgess2-6/+48
Building on the previous commit, this patch detects when two tests have the same test name and causes Dejagnu to print a new result type '# of duplicate test names' in the result summary. A line starting with 'DUPLICATE: ' is also added to the gdb.sum and gdb.log files. The DUPLICATE markers will be printed the second time a duplicate test name is seen, and every time after that. So you might see: PASS: gdb.base/sometest.exp: foo PASS: gdb.base/sometest.exp: bar PASS: gdb.base/sometest.exp: foo DUPLICATE: gdb.base/sometest.exp: foo PASS: gdb.base/sometest.exp: baz PASS: gdb.base/sometest.exp: foo DUPLICATE: gdb.base/sometest.exp: foo However, the results will report a duplicate count of 1, indicating that just one test name (foo) was duplicated. Currently if the tests are run in parallel mode the new result type is not merged into the combined summary file so users will need to run in non-parallel mode to check this result. Similarly, the 'DUPLICATE: ' markers will not be merged into the final gdb.sum file. A later commit will fix this. gdb/testsuite/ChangeLog: * lib/check-test-names.exp (all_test_names): New module variable. (counts): Add 'duplicates' field. (_check_duplicates): New procedure. (check): Also check for duplicates. (do_log_summary): Print duplicates count. (do_reset_vars): Reset counter for duplicate test names, and discard all know test names.
2020-05-11gdb/testsuite: Detect and warn if paths are used in test namesAndrew Burgess3-0/+148
A new library is introduced that hooks into the core of Dejagnu and detects when a test's name includes either the source or build paths. If any offending test names are detected then Dejagnu will print a new result type, '# of paths in test names'. Users should treat this result type just like other bad results types, and aim not to increase this number. As well as displaying the total number of offending tests as part of the final results, a new marker is included in both the gdb.log and gdb.sum files, this marker starts with 'PATH: ', so an offending test would be expected to appear like this: PASS: gdb.base/sometest.exp: Loaded /path/to/build/testsuite/foo.exe PATH: gdb.base/sometest.exp: Loaded /path/to/build/testsuite/foo.exe This should make it easier to track down offending tests. Currently for a local run on my machine, I don't see any offending test names, but it is possible that different targets, or different configurations, might currently be breaking the no paths rule. In order to get this working I have needed to wrap two core Dejagnu functions, log_summary, and reset_vars. Relying on core functions that are not part of any API is always going to be risky, given the relatively slow rate of Dejagnu change this is probably OK for now, and we can possibly upstream some changes to Dejagnu that would allow this functionality to be supported in a more official way later on. Currently if the tests are run in parallel mode the new result type is not merged into the combined summary file so users will need to run in non-parallel mode to check this result. Similarly, the 'PATH: ' markers will not be merged into the combined summary file. A later commit will fix this. gdb/testsuite/ChangeLog: * lib/gdb.exp: Include check-test-names.exp library. * lib/check-test-names.exp: New file.
2020-05-11Fix Ada value printing on PPC64Tom Tromey4-5/+15
The val_print removal patches introduced an Ada regression on PPC64 (probably any big-endian system). The issue comes because value_field does not understand that Ada wrapper fields can be bitfields that wrap a non-scalar type. In this case the value is already left-justified, so the justification done there does the wrong thing. Perhaps it would be good, eventually, to change value_field to understand this case. In the meantime this implements an Ada-specific solution. gdb/ChangeLog 2020-05-11 Tom Tromey <tromey@adacore.com> * ada-lang.c (ada_value_primitive_field): Now public. * ada-lang.h (ada_value_primitive_field): Declare. * ada-valprint.c (print_field_values): Use ada_value_primitive_field for wrapper fields.

2020-05-11[gdb/testsuite] Fix gdb.cp/cpexprs-debug-types.exp inclusionTom de Vries4-748/+772
When running tests using RUNTESTFLAGS="cpexprs.exp cpexprs-debug-types.exp", we have: ... Running src/gdb/testsuite/gdb.cp/cpexprs-debug-types.exp ... Running src/gdb/testsuite/gdb.cp/cpexprs.exp ... ... In the first test-case, we have -fdebug-types-section as expected: ... Running src/gdb/testsuite/gdb.cp/cpexprs-debug-types.exp ... g++ -fno-stack-protector -fdiagnostics-color=never \ -fdebug-types-section \ -c -g \ -o outputs/gdb.cp/cpexprs-debug-types/cpexprs-debug-types0.o \ src/gdb/testsuite/gdb.cp/cpexprs.cc ... but in the second test-case, we have also have -fdebug-types-section: ... Running src/gdb/testsuite/gdb.cp/cpexprs.exp ... g++ -fno-stack-protector -fdiagnostics-color=never \ -fdebug-types-section \ -c -g -g \ -o outputs/gdb.cp/cpexprs/cpexprs0.o \ src/gdb/testsuite/gdb.cp/cpexprs.cc ... This is due to using a global variable flags, which is set in cpexprs-debug-types.exp and tested for existence in cpexprs.exp. Fix this by using a more robust inclusion mechanism, that is: - move the bulk of the test-case cpexprs.exp to cpexprs.exp.in, - include it from cpexprs.exp and cpexprs-debug-types.exp, and - set flags in both .exp files gdb/testsuite/ChangeLog: 2020-05-11 Tom de Vries <tdevries@suse.de> * gdb.cp/cpexprs.exp: Move everything except flags setting ... * gdb.cp/cpexprs.exp.in: .. here. * gdb.cp/cpexprs-debug-types.exp: Include cpexprs.exp.in instead of cpexprs.exp.
2020-05-11Clean-up gdb.ada test namesKeith Seitz16-47/+86
This patch fixes all duplicate and tail parentheses test names. These can really hinder automated test analysis such as used by the buildbot. Before: $ cat testsuite/gdb.sum | egrep "^(PASS|FAIL|XPASS|XFAIL|KPASS|KFAIL)" \ | sort | uniq -c | sort -n | grep -v " 1 " 2 PASS: gdb.ada/attr_ref_and_charlit.exp: print s'last 2 PASS: gdb.ada/bp_on_var.exp: set breakpoint pending off 2 PASS: gdb.ada/complete.exp: complete p pck.inne 2 PASS: gdb.ada/fun_overload_menu.exp: multiple matches for f (f (1, null)) 2 PASS: gdb.ada/type_coercion.exp: p q 2 PASS: gdb.ada/unc_arr_ptr_in_var_rec.exp: print My_P_Object.Ptr when no longer null 3 PASS: gdb.ada/fun_overload_menu.exp: 1 After: <empty> For parentheses, I've audited all occurrences of trailing parentheses. Most offenders are of the form: gdb_test "p func (..)" $expected_result I've either added a unique test name or simply removed the whitespace between the function name and the argument list. gdb/testsuite/ChangeLog 2020-05-11 Keith Seitz <keiths@redhat.com> * gdb.ada/arrayparam.exp: Resolve duplicate and tail parentheses test names. * gdb.ada/arrayptr.exp: Likewise. * gdb.ada/assign_arr.exp: Likewise. * gdb.ada/attr_ref_and_charlit.exp: Likewise. * gdb.ada/bp_on_var.exp: Likewise. * gdb.ada/call_pn.exp: Likewise. * gdb.ada/complete.exp: Likewise. * gdb.ada/fun_overload_menu.exp: Likewise. * gdb.ada/funcall_param.exp: Likewise. * gdb.ada/funcall_ref.exp: Likewise. * gdb.ada/packed_array_assign.exp: Likewise. * gdb.ada/same_component_name.exp: Likewise. * gdb.ada/type_coercion.exp: Likewise. * gdb.ada/unc_arr_ptr_in_var_rec.exp: Likewise. * gdb.ada/variant_record_packed_array.exp: Likewise.
2020-05-11[gdb/symtab] Save modules in .debug_namesTom de Vries2-0/+7
When running test-case gdb.fortran/info-modules.exp with target board debug-names, I run into: ... FAIL: gdb.fortran/info-modules.exp: info modules: check for entry \ 'info-types-2.f90', '18', 'mod2' ... In more detail, comparing the behaviour of the executable without and with .debug_names section, we have: ... -$ gdb -batch info-modules -ex "info modules" +$ gdb -batch info-modules.debugnames -ex "info modules" All defined modules: -File /data/gdb_versions/devel/src/gdb/testsuite/gdb.fortran/info-types-2.f90: -18: mod2 - File /data/gdb_versions/devel/src/gdb/testsuite/gdb.fortran/info-types.f90: 16: mod1 ... This is due to the fact that the .debug_names section does not contain DW_TAG_module entries. Fix this in debug_names::psymbol_tag. Build and tested on x86_64-linux with target board debug-names. gdb/ChangeLog: 2020-05-11 Tom de Vries <tdevries@suse.de> * dwarf2/index-write.c (debug_names::psymbol_tag): Handle MODULE_DOMAIN.
2020-05-11[gdb/symtab] Fix incomplete CU list assert in .debug_namesTom de Vries8-108/+260
Consider the following two-file test-case: ... $ cat main.c extern int foo (void); int main (void) { int sum, a, b; sum = a + b + foo (); return sum; } $ cat foo.c int foo (void) { return 3; } ... Compiled like this: ... $ clang-10 -gdwarf-5 -gpubnames -c main.c $ clang-10 -gdwarf-5 -c foo.c $ clang-10 -gdwarf-5 -gpubnames main.o foo.o ... When loading this exec into gdb, we run into this assert: ... $ gdb a.out Reading symbols from a.out... warning: Section .debug_aranges in a.out entry at offset 0 \ debug_info_offset 0 does not exists, ignoring .debug_aranges. src/gdb/dwarf2/read.c:6949: \ internal-error: cutu_reader::cutu_reader(dwarf2_per_cu_data*, \ abbrev_table*, int, bool): \ Assertion `this_cu->length == cu->header.get_length ()' failed. ... The problem is that the determined length of the CU: ... (gdb) p /x this_cu->length $4 = 0x26a ... does not match the actual length: ... (gdb) p /x cu->header.get_length () $5 = 0x59 ... The length of the CU is determined in create_cus_from_debug_names_list, and set based on this list in the .debug_names section: ... Compilation Unit offsets [ CU[0]: 0x000000c7 ] ... and it is assumed that this is a complete list, so the size of the CU is calculated using the end of the .debug_section at 0x331, making it 0x331 - 0xc7 == 0x26a. However, the CU list is not complete: ... $ llvm-dwarfdump -debug-info a.out \ | grep "Compile Unit" \ | sed 's/Compile Unit.*//' 0x00000000: 0x0000002e: 0x000000a5: 0x000000c7: 0x00000120: 0x00000157: 0x0000030f: ... In particular, because the CU for foo.c is there at 0x120 (the rest of the CUs is due to openSUSE having debug info for various linked in objects). Fix the assert by not assuming to know the length of CUs in create_cus_from_debug_names_list (if the .debug_names is not produced by GDB), and setting it to 0, and setting it later to the actual length. Note that this does not fix the .debug_aranges warning, that's PR25969.
