Jerome Guitton [Wed, 12 Feb 2014 11:08:23 +0000 (12:08 +0100)]
[Ada] Full view of tagged type with ptype

When evaluating an expression, if it is of a tagged type, GDB reads
the tag in memory and deduces the full view. At parsing time, however,
this operation is done only in the case of OP_VAR_VALUE. ptype does
not go through a full evaluation of expressions so it may return some
odd results:

 (gdb) print c.menu_name
 $1 = 0x0
 (gdb) ptype $
 type = system.strings.string_access
 (gdb) ptype c.menu_name
 type = <void>

This change removes this peculiarity by extending the tag resolution
to UNOP_IND and STRUCTOP_STRUCT. As in the case of OP_VAR_VALUE, this
implies switching from EVAL_AVOID_SIDE_EFFECTS to EVAL_NORMAL when a
tagged type is dereferenced.

Alan Modra [Sat, 8 Mar 2014 02:35:06 +0000 (13:05 +1030)]
Better overflow checking for powerpc32 relocations

Similar to the powerpc64 patch, this improves overflow checking in
elf32-ppc.c.  Many reloc "howto" entries needed fixes, some just
cosmetic.

The patch also fixes the R_PPC_VLE_SDA21 reloc application code, which
was horribly broken.  In fact, it may still be broken since Power ISA
2.07 says e_li behaves as
   RT <- EXTS(li20 1:4 || li20 5:8 || li20 0 || li20 9:19)
where li20 is a field taken from bits 17..20, 11..15, 21..31 of the
instruction.  Freescale VLEPEM says differently, and I assume
correctly, that
   RT <- EXTS(li20 0:3 || li20 4:8 || li20 9:19)
The VLE_SDA21 relocation description matches this too.

Now the VLE_SDA21 relocation specifies in the case where e_addi16 is
converted to e_li for symbols in .PPC.EMB.sdata0 or .PPC.EMB.sbss0
(no base register), that the field is restricted to 16 bits, with the
sign bit being propagated to the top 4 bits.  I don't see the sense in
restricting the value like this, so have allowed the full 20 bit
signed value.  This of course is compatible with the reloc description
in that values in the 16 bit signed range will result in exactly the
same insn field as when the reloc description is followed to the
letter.

* elf32-ppc.c (ppc_elf_howto_raw): Correct overflow check for
many relocations.  Correct bitsize and rightshift too for a number

Better overflow checking for powerpc64 relocations

R_PPC64_ADDR16 is used in three contexts:
- .short data relocation
- 16-bit signed insn fields, eg. addi
- 16-bit unsigned insn fields, eg. ori
In the first case we want to allow both signed and unsigned 16-bit
values, the latter two ought to error if the field exceeds the range
of values allowed for 16-bit signed and unsigned integers
respectively.  These conflicting requirements meant that ld had to
choose the least restrictive overflow checks, and thus it is possible
to construct testcases where an addi field overflows but is not
reported by ld.  Many relocations dealing with 16-bit insn fields have
this problem.  What's more, some relocations that are only ever used
for signed fields of instructions woodenly copied the lax overflow

In non-stop mode, or rather, breakpoints always-inserted mode, the
code cache can easily end up with stale breakpoint instructions:

All it takes is filling a cache line when breakpoints already exist in
that memory region, and then delete the breakpoint.

Vis. (from the new test):

    0x0000000000400554 <+24>:    retq
 End of assembler dump.

So far so good.  Now flush the code cache:

 (gdb) set code-cache off
 (gdb) set code-cache on

Requesting a disassembly works as expected, breakpoint shadowing is
applied:

Those breakpoint instructions are no longer installed in target memory
they're stale in the code cache.  Easily confirmed by just disabling
the code cache:

 (gdb) set code-cache off
 (gdb) disass main

I stumbled upon this when writing a patch to infrun.c, that made
handle_inferior_event & co fill in the cache before breakpoints were
removed from the target.  Recall that wait_for_inferior flushes the
dcache for every event.  So in that case, always-inserted mode was not
necessary to trigger this.  It's just a convenient way to expose the
issue.

The dcache works at the raw memory level.  We need to update it
whenever memory is written, no matter what kind of target memory
object was originally passed down by the caller.  The issue is that
the dcache update code isn't reached when a caller explicitly writes
raw memory.  Breakpoint insertion/removal is one such case --
mem-break.c uses target_write_read_memory/target_write_raw_memory.

The fix is to move the dcache update code from memory_xfer_partial_1
to raw_memory_xfer_partial so that it's always reachable.

When we do that, we can actually simplify a series of things.
memory_xfer_partial_1 no longer needs to handle writes for any kind of
memory object, and therefore dcache_xfer_memory no longer needs to
handle writes either.  So the latter (dcache_xfer_memory) and its
callees can be simplified to only care about reads.  While we're
touching dcache_xfer_memory's prototype, might as well rename it to
reflect that fact that it only handles reads, and make it follow the
new target_xfer_status/xfered_len style.  This made me notice that
dcache_xfer_memory loses the real error status if a memory read fails:
we could have failed to read due to TARGET_XFER_E_UNAVAILABLE, for
instance, but we always return TARGET_XFER_E_IO, hence the FIXME note.
I felt that fixing that fell out of the scope of this patch.

Currently dcache_xfer_memory handles the case of a write failing.  The
whole cache line is invalidated when that happens.  However,
dcache_update, the sole mechanism for handling writes that will remain
after the patch, does not presently handle that scenario.  That's a
bug.  The patch makes it handle that, by passing down the
target_xfer_status status from the caller, so that it can better
decide what to do itself.  While I was changing the function's
prototype, I constified the myaddr parameter, getting rid of the need
for the cast as seen in its existing caller.

Tested on x86_64 Fedora 17, native and gdbserver.

After this, when a probe's address is needed, it is determined by
applying offsets at the point of use.
