## Test that "llvm-objdump --traceback-table" decodes the ControlledStorageInfo,
## AllocaRegister, and extension table of the traceback table.

## The above .text section data is generated using the compiler command:
## xlc -o test.o -c test.c
## We also modified the binary content of the traceback table in the object file to add vector information
## for function "foo", including ControlledStorageInfo, AllocaRegister, and ExtensionTable.
## test.c:
## int AddNum(int i,intj) {
## return i+j;
## }
## float foo(int i1,float f1,double d1,int i2, float f2) {
## return i1+f1+d1+i2+f2;
## }
