2013-09-02server.c:gdb_read_memory: Fix error return.Pedro Alves2-1/+6
When I added gdb_read_memory, with bits factored out from elsewhere, I missed adjusting this error return. gdb_read_memory has an interface similar to Like GDB's xfer_partial: > /* Read trace frame or inferior memory. Returns the number of bytes > actually read, zero when no further transfer is possible, and -1 on > error. Return of a positive value smaller than LEN does not > indicate there's no more to be read, only the end of the transfer. Returning EIO, a positive value, is obviously bogus, for the caller will confuse it with a successful partial transfer. Found by inspection. Tested on x86_64 Fedora 17. gdb/gdbserver/ 2013-09-02 Pedro Alves <palves@redhat.com> * server.c (gdb_read_memory): Return -1 on traceframe memory read error instead of EIO.

2013-08-30MI -trace-find, print frame with LOC_AND_ADDRESS instead of SRC_AND_LOC.Pedro Alves2-1/+6
When I looked for print_stack_frame calls in MI, I wondered why this one passing down SRC_AND_LOC. print_stack_frame does: /* For mi, alway print location and address. */ if (ui_out_is_mi_like_p (current_uiout)) print_what = LOC_AND_ADDRESS; So it really doesn't matter which value is passed down, but, to avoid confusion in readers, it's better to use the MI standard here. There's another SRC_AND_LOC in mi-interp.c, but that one makes sense. gdb/ 2013-08-30 Pedro Alves <palves@redhat.com> * mi/mi-main.c (mi_cmd_trace_find): Use LOC_AND_ADDRESS instead of SRC_AND_LOC.
2013-08-30restore_selected_frame: tweak warning.Pedro Alves2-2/+7
I noticed SRC_LINE has special handling within print_stack_frame (mid statement handling), so I audited all uses, and noticed the one in restore_selected_frame. I actually added this warning myself back in 2008, but reading back, I think we can do better. "reparsed frame" is probably confusing to users. Old: warning: Couldn't restore frame #2 in current thread, at reparsed frame #0 45 w = 0; (gdb) New: warning: Couldn't restore frame #2 in current thread. Bottom (innermost) frame selected: #0 foo () at foo.c:45 45 w = 0; (gdb) Tested on x86_64 Fedora 17. gdb/ 2013-08-30 Pedro Alves <palves@redhat.com> * thread.c (restore_selected_frame): Use SRC_AND_LOC, and change warning text.
2013-08-30bsd-kvm.c: Fix arguments to print_stack_frame.Pedro Alves2-3/+8
1 is SRC_AND_LOC. Then, this is passing -1 as print_level argument to print_stack_frame. -1 is not a valid print_level value (it's a regular boolean). But, it used to be, before <https://sourceware.org/ml/gdb-patches/2004-04/msg00585.html>. What happened is that bsd-kvm.c did not exist at the time of that patch, but went into the tree about a month after, without being adjusted to the new interface. Fixed now, exactly as e.g., ocd.c had been adjusted: > --- ocd.c 18 Jan 2004 19:26:51 -0000 1.28 > +++ ocd.c 23 Apr 2004 14:29:12 -0000 > @@ -225,7 +225,7 @@ > flush_cached_frames (); > registers_changed (); > stop_pc = read_pc (); > - print_stack_frame (get_selected_frame (), -1, 1); > + print_stack_frame (get_selected_frame (), 0, SRC_AND_LOC); gdb/ 2013-08-30 Pedro Alves <palves@redhat.com> * bsd-kvm.c (bsd_kvm_open, bsd_kvm_proc_cmd, bsd_kvm_pcb_cmd): Adjust arguments to print_stack_frame.

2013-08-29thread support broken on ppc-aix.Joel Brobecker2-1/+6
Thread support got broken when adding 64bit support on ppc-aix. Upon digging further, I found that the following patch... | * gdb_ptrace.h: Use ptrace64 instead of ptrace if HAVE_PTRACE64 | is defined. | * rs6000-nat.c: Check for __ld_info64_ if compiling 64 BIT gdb. | (rs6000_ptrace32): Call ptrace64 instead of ptrace if present. | (rs6000_ptrace64): Call ptace64 instead of ptracex if present. | * configure.ac: Check for ptrace64. | * configure, config.in: Regenerate. ... is responsible for this regression: (gdb) x /x &__n_pthreads 0xf06a8258 <__n_pthreads>: Cannot access memory at address 0xf06a8258 Prior to the patch, we have: (gdb) x /x &__n_pthreads 0xf06a8258 <__n_pthreads>: 0x00000003 The problem occurs inside rs6000_ptrace32, while calling ptrace64. The address is given to rs6000_ptrace32 as an "int *", while ptrace64 takes a "long long". The cast causes the address to be sign-extended, which results in GDB trying to read the wrong address. This patch fixes the issue by casting the address to a "uintptr_t" instead, and letting the compiler do the implicit conversion to "long long" in the function call. gdb/ChangeLog: * rs6000-nat.c (rs6000_ptrace32): Cast "addr" to "uintptr_t" instead of "long long" in call to ptrace64.
