> * gdb.base/shreloc1.c (fn_1): Reference variable static_var_1.
> * gdb.base/shreloc2.c (fn_2): Reference variable static_var_2.

Hi Daniel,
Thanks for pointing out these errors for me. Followed is the re-worked
patch.

Wu Zhou <woodzltc@cn.ibm.com>
* gdb.base/shreloc.exp: Use gdb_compile_shlib. Add support for
IBM's xlc compiler.
* gdb.base/shreloc1.c (fn_1): Reference variable static_var_1.
* gdb.base/shreloc2.c (fn_2): Reference variable static_var_2.
