[AArch64] Use int64_t for address offset

In AArch64 displaced stepping and fast tracepoint, GDB/GDBserver needs
to check whether the offset can fit in the range.  We are using int32_t
for offset, it is sufficient to get an offset from an instruction, but
it is not enough to get an offset from two addresses.  For example,
we have a BL in shared lib which is at 0x0000002000040774, and the
scratch pad for displaced stepping is at 0x400698.  The offset can't
fit in 28 bit imm.  However, since we are using int32_t for offset, GDB
thinks the offset can fit it, and generate the B instruction with wrong
offset.

a full 64-bit field for the index.  I went for the latter for two
reasons:

      - Doing the range checking in operand_general_constraint_met_p
        seems structurally cleaner than doing it while parsing.

      - The bitfields didn't really buy us anything.  The imm field
        of the union is already 128 bits, so we can use a full int64_t
        index without growing the structure.

The patch also adds missing range checks for the elements in a register
list index.

which removed a preparatory call to `mips16_extended_frag' previously
made from `md_estimate_size_before_relax'.  As a result the function is
never called with its `sec' parameter non-NULL and consequently all the
unsupported relocation checks within are dead and never trigger, causing
any unhandled relocations to silently resolve to 0.  Unfortunately there
was no sufficient test suite coverage back then to catch this.

Remove all dead code then, and all the associated comments.  Update the
remaining call to `mips16_extended_frag' from `mips_relax_frag' to pass
the relocation section as the `sec' parameter and use it to mark frags
which require an external relocation, as extended.  Finally handle any

8 years agoAdd support for catching system calls to native FreeBSD targets.
John Baldwin [Mon, 13 Jun 2016 04:24:42 +0000 (21:24 -0700)]
Add support for catching system calls to native FreeBSD targets.

All platforms on FreeBSD use a shared system call table, so use a
single XML file to describe the system calls available on each FreeBSD
platform.

Recent versions of FreeBSD include the identifier of the current
system call when reporting a system call entry or exit event in the
ptrace_lwpinfo structure obtained via PT_LWPINFO in fbsd_wait.  As
such, FreeBSD native targets do not use the gdbarch method to fetch
the system call code.  In addition, FreeBSD register sets fetched via
ptrace do not include an equivalent of 'orig_rax' (on amd64 for
example), so the system call code cannot be extracted from the
available registers during a system call exit.  However, GDB assumes
that system call catch points are not supported if the gdbarch method
is not present.  As a workaround, FreeBSD ABIs install a dummy gdbarch
method that throws an internal_error if it is ever invoked.

gdb/ChangeLog:

* configure.ac: Check for support for system call LWP fields on
FreeBSD.
* config.in, configure: Rebuild.

Different platforms have different meanings for auxiliary vector

fprint_target_auxv into a new default_print_auxv_entry function.
default_print_auxv_entry chooses an appropriate format and description
