Subject: fix gdb.base/access-mem-running.exp for clang testing
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=96ca89d245e262578ef565247c1d68dff493d8a3;p=binutils-gdb.git

fix gdb.base/access-mem-running.exp for clang testing

Clang was optimizing global_var away because it was not being used
anywhere. this commit fixes that by adding the attribute used it.
