Manman Ren [Tue, 29 Oct 2013 22:57:10 +0000 (22:57 +0000)]
Debug Info: support for DW_FORM_ref_addr.

To support ref_addr, we calculate the section offset of a DIE (i.e. offset
of a DIE from beginning of the debug info section). The Offset field in DIE
is currently CU-relative. To calculate the section offset, we add a
DebugInfoOffset field in CompileUnit to store the offset of a CU from beginning
of the debug info section. We set the value in DwarfUnits::computeSizeAndOffset
for each CompileUnit.

A helper function DIE::getCompileUnit is added to return the CU DIE that
the input DIE belongs to. We also add a map CUDieMap in DwarfDebug to help
finding the CU for a given CU DIE.

For a cross-referenced DIE, we first find the CU DIE it belongs to with
getCompileUnit, then we use CUDieMap to get the corresponding CU for the CU DIE.
Adding the section offset of the CU with the CU-relative offset of a DIE gives
us the seciton offset of the DIE.

We correctly emit ref_addr with relocation using EmitLabelPlusOffset when
doesDwarfUseRelocationsAcrossSections is true.

This commit handles the emission of DW_FORM_ref_addr when we have an attribute
with FORM_ref_addr. A follow-on patch will start using ref_addr when adding a
DIEEntry. This commit will be tested and verified in the follow-on patch.

Matt Arsenault [Tue, 29 Oct 2013 20:59:29 +0000 (20:59 +0000)]
Workaround MSVC 32-bit miscompile of getCondCodeAction.

Use 32-bit types for the array instead of 64. This should
generally be better anyway.

In optimized + assert builds, I saw a failure when a
cond code / type combination that is never set was loading
a non-zero value and hitting the != Promote assert.

It turns out when loading the 64-bit value to do the shift,
the assembly loads the 2 32-bit halves from non-consecutive
addresses. The address the second half of the loaded uint64_t
doesn't include the offset of the array in the struct. Instead
of being offset + 4, it's just + 4.

I'm not entirely sure why this wasn't observed before.
setCondCodeAction isn't heavily used by the in-tree targets,
and not with the higher valued vector SimpleValueTypes. Only
PPC is using one of the > 32 valued types, and that is probably
never used by anyone on a 32-bit MSVC compiled host.

I ran into this when upgrading LLVM versions, so I guess the
value loaded from the nonsense address happened to work out
before.

No test since I'm not really sure if / how it can be reproduced
with the current in tree targets, and it's not supposed to change
anything.
