2016-10-06Remove Java supportTom Tromey1-2/+2
This patch removes the Java support from gdb. gcj has not seen much development or use for years now, and was recently removed from GCC. This patch changes gdb to follow; in the unlikely event that there are still users using gcj, they can continue to use an older gdb to debug. Or, they can debug in C++ mode.

2016-01-13Per-inferior/Inferior-qualified thread IDsPedro Alves1-5/+6
This commit changes GDB to track thread numbers per-inferior. Then, if you're debugging multiple inferiors, GDB displays "inferior-num.thread-num" instead of just "thread-num" whenever it needs to display a thread: (gdb) info inferiors Num Description Executable 1 process 6022 /home/pedro/gdb/tests/threads * 2 process 6037 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame 1.1 Thread 0x7ffff7fc2740 (LWP 6022) "threads" (running) 1.2 Thread 0x7ffff77c0700 (LWP 6028) "threads" (running) 1.3 Thread 0x7ffff7fc2740 (LWP 6032) "threads" (running) 2.1 Thread 0x7ffff7fc1700 (LWP 6037) "threads" (running) 2.2 Thread 0x7ffff77c0700 (LWP 6038) "threads" (running) * 2.3 Thread 0x7ffff7fc2740 (LWP 6039) "threads" (running) (gdb) ... (gdb) thread 1.1 [Switching to thread 1.1 (Thread 0x7ffff7fc2740 (LWP 8155))] (gdb) ... etc. You can still use "thread NUM", in which case GDB infers you're referring to thread NUM of the current inferior. The $_thread convenience var and Python's InferiorThread.num attribute are remapped to the new per-inferior thread number. It's a backward compatibility break, but since it only matters when debugging multiple inferiors, I think it's worth doing. Because MI thread IDs need to be a single integer, we keep giving threads a global identifier, _in addition_ to the per-inferior number, and make MI always refer to the global thread IDs. IOW, nothing changes from a MI frontend's perspective. Similarly, since Python's Breakpoint.thread and Guile's breakpoint-thread/set-breakpoint-thread breakpoint methods need to work with integers, those are adjusted to work with global thread IDs too. Follow up patches will provide convenient means to access threads' global IDs. To avoid potencially confusing users (which also avoids updating much of the testsuite), if there's only one inferior and its ID is "1", IOW, the user hasn't done anything multi-process/inferior related, then the "INF." part of thread IDs is not shown. E.g,.: (gdb) info inferiors Num Description Executable * 1 process 15275 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame * 1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) add-inferior Added inferior 2 (gdb) info threads Id Target Id Frame * 1.1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) No regressions on x86_64 Fedora 20. gdb/ChangeLog: 2016-01-13 Pedro Alves <palves@redhat.com> * NEWS: Mention that thread IDs are now per inferior and global thread IDs. * Makefile.in (SFILES): Add tid-parse.c.

2014-05-30Add a TRY_CATCH to get_prev_frame_always to better manage errors during unwind.Andrew Burgess1-0/+3
https://sourceware.org/ml/gdb-patches/2014-05/msg00737.html Currently a MEMORY_ERROR raised during unwinding a frame will cause the unwind to stop with an error message, for example: (gdb) bt #0 breakpt () at amd64-invalid-stack-middle.c:27 #1 0x00000000004008f0 in func5 () at amd64-invalid-stack-middle.c:32 #2 0x0000000000400900 in func4 () at amd64-invalid-stack-middle.c:38 #3 0x0000000000400910 in func3 () at amd64-invalid-stack-middle.c:44 #4 0x0000000000400928 in func2 () at amd64-invalid-stack-middle.c:50 Cannot access memory at address 0x2aaaaaab0000 However, frame #4 is marked as being the end of the stack unwind, so a subsequent request for the backtrace looses the error message, such as: (gdb) bt #0 breakpt () at amd64-invalid-stack-middle.c:27 #1 0x00000000004008f0 in func5 () at amd64-invalid-stack-middle.c:32 #2 0x0000000000400900 in func4 () at amd64-invalid-stack-middle.c:38 #3 0x0000000000400910 in func3 () at amd64-invalid-stack-middle.c:44 #4 0x0000000000400928 in func2 () at amd64-invalid-stack-middle.c:50 When fetching the backtrace, or requesting the stack depth using the MI interface the situation is even worse, the first time a request is made we encounter the memory error and so the MI returns an error instead of the correct result, for example: (gdb) -stack-info-depth ^error,msg="Cannot access memory at address 0x2aaaaaab0000" Or, (gdb) -stack-list-frames ^error,msg="Cannot access memory at address 0x2aaaaaab0000" However, once one of these commands has been used gdb has, internally, walked the stack and figured that out that frame #4 is the bottom of the stack, so the second time an MI command is tried you'll get the "expected" result: (gdb) -stack-info-depth ^done,depth="5" Or, (gdb) -stack-list-frames ^done,stack=[frame={level="0", .. snip lots .. }] After this patch the MEMORY_ERROR encountered during the frame unwind is attached to frame #4 as the stop reason, and is displayed in the CLI each time the backtrace is requested. In the MI, catching the error means that the "expected" result is returned the first time the MI command is issued. So, from the CLI the results of the backtrace will be: (gdb) bt #0 breakpt () at amd64-invalid-stack-middle.c:27 #1 0x00000000004008f0 in func5 () at amd64-invalid-stack-middle.c:32 #2 0x0000000000400900 in func4 () at amd64-invalid-stack-middle.c:38 #3 0x0000000000400910 in func3 () at amd64-invalid-stack-middle.c:44 #4 0x0000000000400928 in func2 () at amd64-invalid-stack-middle.c:50 Backtrace stopped: Cannot access memory at address 0x2aaaaaab0000 Each and every time that the backtrace is requested, while the MI output will similarly be consistently: (gdb) -stack-info-depth ^done,depth="5" Or, (gdb) -stack-list-frames ^done,stack=[frame={level="0", .. snip lots .. }] gdb/ChangeLog: * frame.c (struct frame_info): Add stop_string field.
