   section.
2) When creating a fragment in a .zdebug_* section, make it a compressed

3) When computing the size of a compressed section, compress the data

Rafael Espindola [Thu, 27 Mar 2014 15:26:56 +0000 (15:26 +0000)]
Prevent alias from pointing to weak aliases.

This adds back r204781.

Original message:

Aliases are just another name for a position in a file. As such, the
regular symbol resolutions are not applied. For example, given

define void @my_func() {
  ret void
}
@my_alias = alias weak void ()* @my_func
@my_alias2 = alias void ()* @my_alias

We produce without this patch:

        .weak   my_alias
my_alias = my_func
        .globl  my_alias2
my_alias2 = my_alias

That is, in the resulting ELF file my_alias, my_func and my_alias are
just 3 names pointing to offset 0 of .text. That is *not* the
semantics of IR linking. For example, linking in a

@my_alias = alias void ()* @other_func

would require the strong my_alias to override the weak one and
my_alias2 would end up pointing to other_func.

There is no way to represent that with aliases being just another
name, so the best solution seems to be to just disallow it, converting
a miscompile into an error.

10 years agoFix a problem with the ARM assembler incorrectly matching a
Kevin Enderby [Wed, 26 Mar 2014 21:54:11 +0000 (21:54 +0000)]
Fix a problem with the ARM assembler incorrectly matching a
vector list parameter that is using all lanes "{d0[], d2[]}" but can
match and instruction with a ”{d0, d2}" parameter.

I’m finishing up a fix for proper checking of the unsupported
alignments on vld/vst instructions and ran into this.  Thus I don’t
have a test case at this time.  And adding all code that will
demonstrate the bug would obscure the very simple one line fix.
So if you would indulge me on not having a test case at this
time I’ll instead offer up a detailed explanation of what is
going on in this commit message.

This instruction:

vld2.8  {d0[], d2[]}, [r4:64]

is not legal as the alignment can only be 16 when the size is 8.
Per this documentation:

A8.8.325 VLD2 (single 2-element structure to all lanes)
 <align> The alignment. It can be one of:
16 2-byte alignment, available only if <size> is 8, encoded as a = 1.
32 4-byte alignment, available only if <size> is 16, encoded as a = 1.
64 8-byte alignment, available only if <size> is 32, encoded as a = 1.
omitted Standard alignment, see Unaligned data access on page A3-108.

So when code is added to the llvm integrated assembler to not match
that instruction because of the alignment it then goes on to try to match
other instructions and comes across this:

vld2.8  {d0, d2}, [r4:64]

and and matches it. This is because of the method
ARMOperand::isVecListDPairSpaced() is missing the check of the Kind.
In this case the Kind is k_VectorListAllLanes . While the name of the method
may suggest that this is OK it really should check that the Kind is
k_VectorList.

As the method ARMOperand::isDoubleSpacedVectorAllLanes() is what was
used to match {d0[], d2[]}  and correctly checks the Kind:

  bool isDoubleSpacedVectorAllLanes() const {
    return Kind == k_VectorListAllLanes && VectorList.isDoubleSpaced;
  }

where the original ARMOperand::isVecListDPairSpaced() does not check
the Kind:

  bool isVecListDPairSpaced() const {
    if (isSingleSpacedVectorList()) return false;
    return (ARMMCRegisterClasses[ARM::DPairSpcRegClassID]
              .contains(VectorList.RegNum));
  }

Jim Grosbach has reviewed the change and said:  Yep, that sounds right. …
And by "right" I mean, "wow, that's a nasty latent bug I'm really, really
glad to see fixed." :)

Fix for incorrect address sinking in the presence of potential overflows.

In some cases it is possible for CGP to attempt to reuse a base address from
another basic block. In those cases we have to be sure that all the address
math was either done at the same bit width, or that none of it overflowed

This didn't work. I was ending up with code like this:

  lea     edi,[esi+38h]
  mov     ecx,0Fh
  mov     edx,esi
  mov     esi,ebx
  rep movs dword ptr es:[edi],dword ptr [esi]
  lea     ecx,[esi+74h] <-- Ooops, we're now using esi before restoring it from edx.
  add     ebx,3Ch
  mov     esi,edx

I guess if we want to do this we need stronger glue or something, or doing the expansion
much later.
