--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
The testcase is invalid since
'--wrap=SYMBOL'
Use a wrapper function for SYMBOL. Any undefined reference to
SYMBOL will be resolved to '__wrap_SYMBOL'. Any undefined
reference to '__real_SYMBOL' will be resolved to SYMBOL.
This can be used to provide a wrapper for a system function. The
wrapper function should be called '__wrap_SYMBOL'. If it wishes to
call the system function, it should call '__real_SYMBOL'.
When SYMBOL definition is compiled with LTO, LTO will resolve all SYMBOL
references to SYMBOL definition in LTO since LTO doesn't know --wrap.
