2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess1-1/+1
This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.
2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker1-1/+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.
2022-10-21gdb/reverse: Fix stepping over recursive functionsBruno Larsen1-1/+18
Currently, when using GDB to do reverse debugging, if we try to use the command "reverse next" to skip a recursive function, instead of skipping all of the recursive calls and stopping in the previous line, we stop at the second to last recursive call, and need to manually step backwards until we leave the first call. This is well documented in PR gdb/16678. This bug happens because when GDB notices that a reverse step has entered into a function, GDB will add a step_resume_breakpoint at the start of the function, then single step out of the prologue once that breakpoint is hit. The problem was happening because GDB wouldn't give that step_resume_breakpoint a frame-id, so the first time the breakpoint was hit, the inferior would be stopped. This is fixed by giving the current frame-id to the breakpoint. This commit also changes gdb.reverse/step-reverse.c to contain a recursive function and attempt to both, skip it altogether, and to skip the second call from inside the first call, as this setup broke a previous version of the patch.

2020-07-21[gdb/testsuite] Fix step-reverse.c with gcc-10Tom de Vries1-1/+1
The file gdb.reverse/step-reverse.c is used in test-cases: - gdb.reverse/step-reverse.exp - gdb.reverse/next-reverse-bkpt-over-sr.exp - gdb.reverse/step-precsave.exp With gcc-7, there are only PASSes (apart from one KFAIL), but with gcc-10, we have the following FAILs: ... FAIL: gdb.reverse/step-reverse.exp: reverse stepi from a function call \ (start statement) FAIL: gdb.reverse/step-reverse.exp: simple reverse stepi FAIL: gdb.reverse/step-reverse.exp: reverse step out of called fn FAIL: gdb.reverse/step-reverse.exp: reverse next over call FAIL: gdb.reverse/step-reverse.exp: reverse step test 1 FAIL: gdb.reverse/step-reverse.exp: reverse next test 1 FAIL: gdb.reverse/step-reverse.exp: reverse step test 2 FAIL: gdb.reverse/step-reverse.exp: reverse next test 2 FAIL: gdb.reverse/step-precsave.exp: reverse stepi from a function call \ (start statement) FAIL: gdb.reverse/step-precsave.exp: simple reverse stepi FAIL: gdb.reverse/step-precsave.exp: reverse step out of called fn FAIL: gdb.reverse/step-precsave.exp: reverse next over call FAIL: gdb.reverse/step-precsave.exp: reverse step test 1 FAIL: gdb.reverse/step-precsave.exp: reverse next test 1 FAIL: gdb.reverse/step-precsave.exp: reverse step test 2 FAIL: gdb.reverse/step-precsave.exp: reverse next test 2 ... Looking at the first step-precsave.exp FAIL, we have: ... (gdb) stepi^M 26 myglob++; return 0; /* ARRIVED IN CALLEE */^M (gdb) PASS: gdb.reverse/step-precsave.exp: reverse stepi thru function return stepi^M 0x000000000040055f 26 myglob++; return 0; /* ARRIVED IN CALLEE */^M (gdb) FAIL: gdb.reverse/step-precsave.exp: reverse stepi from a function call \ (start statement) ... There's a difference in line info for callee: ... 25 int callee() { /* ENTER CALLEE */ 26 myglob++; return 0; /* ARRIVED IN CALLEE */ 27 } /* RETURN FROM CALLEE */ ... between gcc-7: ... Line number Starting address View Stmt 25 0x400557 x 26 0x40055b x 27 0x40056f x ... and gcc-10: ... 25 0x400552 x 26 0x400556 x 26 0x400565 x 27 0x40056a x ... The two "recommend breakpoint location" entries at line 26 are for the two statements ("myglob++" and "return 0"), but the test-case expects to hit line 26 only once. Fix this by rewriting the two statements into a single statement: ... - myglob++; return 0; /* ARRIVED IN CALLEE */ + return myglob++; /* ARRIVED IN CALLEE */ ... Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2020-07-21 Tom de Vries <tdevries@suse.de> * gdb.reverse/step-reverse.c (callee): Merge statements.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+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.
