AArch64: Set the correct ELF class for AArch64 stubs (PR/25210)
This fixes PR 25210 by specifying the the correct ELF class for AArch64 stubs.
After doing this the stub section starts behaving like a normal object file
loaded from disk. That is SEC_LINKER_CREATED causes us to have to write the
section manually.
This flag was added as a fix for PR 24753. I believe that
fix to still be correct as linker created sections don't have a size on disk
and it fixes the Arm bootstrap regression. But in this case specifying the
correct section class also makes the stub section not be considered by
compress.c.
So I'm partially revert this change so that we don't have to manage the section
manually as implied by SEC_LINKER_CREATED.

[PATCH] Adjust test gdb.ada/ptype_tagged_param.exp for when GNAT runtime does not have debug info
This test verifies that GDB correctly identifies the run-time type of
"s" as being the type "Circle". However, that can only be done
correctly if the GNAT runtime has been compiled and shipped with debug
information, so that GDB can poke in its internal data structures.
Currently the test fails when when running against a GNAT runtime
without debug info. This is the case, for example, on Arch Linux using
the distribution package.
This patch adds a helper in lib/ada.exp to check whether the GNAT
runtime has debug info or not. It then uses it in
gdb.ada/ptype_tagged_param.exp to expect a different result, depending
on whether we have debug info or not in the runtime.
At first, I made it so we would XFAIL the test, in the absence of debug
info, but then I thought that we might as well test for the output we
expect in the absence of debug info instead.

x86-64: fix Intel64 handling of branch with data16 prefix
The expectation of x86-64-branch-3 for "call" / "jmp" with an obvious
direct destination to translate to an indirect _far_ branch is plain
wrong. The operand size prefix should have no effect at all on the
interpretation of the operand. The main underlying issue here is that
the Intel64 templates of the direct branches don't include Disp16, yet
various assumptions exist that it would always be there when there's
also Disp32/Disp32S, toggled by the operand size prefix (which is
being ignored by direct branches in Intel64 mode).
Along these lines it was also wrong to base the displacement width
decision solely on the operand size prefix: REX.W cancels this effect
and hence needs taking into consideration, too.
A disassembler change is needed here as well: XBEGIN was wrongly treated
the same as direct CALL/JMP, which isn't the case - the operand size
prefix does affect displacement size there, it's merely ignored when it
comes to updating [ER]IP.
Jan Beulich [Fri, 27 Dec 2019 08:22:03 +0000 (09:22 +0100)]
x86: consolidate Disp<NN> handling a little
In memory operand addressing, which forms of displacement are permitted
besides Disp8 is pretty clearly limited
- outside of 64-bit mode, Disp16 or Disp32 only, depending on address
size (MPX being special in not allowing Disp16),
- in 64-bit mode, Disp32s or Disp64 without address size override, and
solely Disp32 with one.
Adjust assembler and i386-gen to match this, observing that templates
already get adjusted before trying to match them against input depending
on the presence of an address size prefix.
This adjustment logic gets extended to all cases, as certain DispNN
values should also be dropped when there's no such prefix. In fact
behavior of the assembler, perhaps besides the exact diagnostics wording,
should not differ between there being templates applicable to 64-bit and
non-64-bit at the same time, or there being fully separate sets of
templates, with their DispNN settings already reduced accordingly.
This adjustment logic further gets guarded such that there wouldn't be
and Disp<N> conversion based on address size prefix when this prefix
doesn't control the width of the displacement (on branches other than
absolute ones).
These adjustments then also allow folding two MOV templates, which had
been split between 64-bit and non-64-bits variants so far.
Once in this area also
- drop the bogus DispNN from JumpByte templates, leaving just the
correct Disp8 there (compensated by i386_finalize_displacement()
now setting Disp8 on their operands),
- add the missing Disp32S to XBEGIN.
Note that the changes make it necessary to temporarily mark a test as
XFAIL; this will get taken care of by a subsequent patch. The failing
parts are entirely bogus and will get replaced.

Avoid ubsan bug complaining about &p->field
I reckon it's quite OK to write &p->field in C when p might be NULL,
and lots of old C programmers probably agree with me. However, ubsan
disagrees and so do some people I respect. I suspect C++ influence is
to blame for the ubsan behaviour. See
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92634. So far no one has
educated me as to why I'm wrong to claim that there isn't anything in
the C standard to say that p->field is always (*p).field. Note 79
doesn't quite do that because it doesn't cover null pointers. If
there was such an equivalence then you could claim &p->field has a
null pointer reference when p is NULL, even though no C compiler would
ever dereference p.

Fix disabling of solib probes when LD_AUDITing
The SVR4 solib event handler determines whether an event is related to a
non-base link namespace by comparing the event's debug struct address
to the debug struct address of the initial program image. However, this
can fail when using LD_AUDIT as audit libraries are loaded before the
loader has initialised the initial program image's debug struct. When
the event handler fails to find the debug struct, the probe-based
debugger interface is disabled and a warning is flagged to the user.
This commit adds a fallback test to help determine whether an event is
for a foreign link namespace when the debug struct isn't available.

* solib-svr4.c (svr4_handle_solib_event): Add fallback link
namespace test for when the debug struct isn't available.
