Summary: "LLVM ERROR: unsupported relocation of variable" from
llc as of @131140
Product: new-bugs
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: new bugs

As of a recent update to dev TOT, I'm seeing this error whenever I try to
generate debugging information with my compiler. Attached is a test case that
reproduces when run through llc. (It is possible that I have a bug in how I
generate debugging metadata that is only being exposed by recent changes to
LLVM, but
the debug info I generated previously seemed to generally work correctly.)
I've attached a test case, that if run through llc to generate a native object
file, gives this error:
% llc bugpoint-reduced-simplified.ll -o a.o -filetype=obj
LLVM ERROR: unsupported relocation of variable 'Ltmp7'
%
I've searched through recent checkins and it seems that this was introduced by
the changes in 131140:

Use .cfi_sections to put the unwind info in .debug_frame when possible.
With
this clang will use .debug_frame in, for example,
clang -g -c -m32 test.c
This matches gcc's behaviour. It looks like .debug_frame is a bit bigger
than .eh_frame, but has the big advantage of not being allocated.
