Valgrind log

Valgrind is reporting memory leaks, some of which are triggered by the
ARM backend. One of the leaks is due to frame indexes being lost, but
the code suggests that these should be managed by the LLVM
infrastructure.

Test case: llvm/test/CodeGen/ARM/2009-02-27-SpillerBug.ll
Run
 valgrind --leak-check=full bin/llc -regalloc=local -march=arm
2009-02-27-SpillerBug.ll

Log file is attached.
