[LLVMbugs] LLVM Bug in HDF5 Compile

[Bill Wendling]

Here's what I get when trying to compile HDF5 with LLVM (a copy
available at
ftp://hdf.ncsa.uiuc.edu/pub/outgoing/wendling/hdf5-llvm.tar.gz)

The original message:

Please submit a full bug report.
See <URL:http://llvm.cs.uiuc.edu> for instructions.

bugpoint command:

[kubrick:src] bugpoint H5E.s -lowersetjmp -funcresolve -raiseallocs
-globaldce -prune-eh -inline -instcombine -raise -tailduplicate
-simplifycfg -scalarrepl -tailcallelim -instcombine -reassociate
-instcombine -simplifycfg -preheaders -licm -load-vn -gcse -sccp
-instcombine -preheaders -indvars -adce -simplifycfg -deadtypeelim
-constmerge

bugpoint output:

*** Attempting to perform final cleanups: Success!
Emitted bytecode to 'bugpoint-reduced-simplified.bc'
 
*** You can reproduce the problem with: opt
bugpoint-reduced-simplified.bc -instcombine

The .bc file is attached.

Cheers!
