## Test how we dump SHT_LLVM_CALL_GRAPH_PROFILE sections for 32 and 64-bit targets.

## Test we use the "Entries" property when it is possible to dump values correctly.

Sections:
## Case 1: Content is empty.
  - Name: .empty
    Type: SHT_LLVM_CALL_GRAPH_PROFILE
## Case 2: Check that we use the "Entries" property to dump the data when it
##         has a size that is a multiple of 16 and is valid (it is possible to match
##         symbol indexes to symbols), but fallback to dumping the whole section
##         using the "Content" property otherwise.
## TODO: Teach yaml2obj to accept 'Size' key for SHT_LLVM_CALL_GRAPH_PROFILE
##       sections and use Entries for cases below.
  - Name: .multiple.8.valid

##         is not a symbol table.
