Subject: [PATCH] cvexpr.c: Don't let linker delete unused globals
Date: Thu, 18 Apr 2002 06:23:00 -0000 [thread overview]
Message-ID: <1020418132243.ZM6877@localhost.localdomain> (raw)
On AIX, I was seeing lots of failures in gdb.base/code-expr.exp and
gdb.base/cvexpr.exp due to the fact that the linker deletes unused
symbols. The patch below fixes these failures.
Committed as obvious.
* gdb.base/cvexpr.c (use): New function.
(main): Invoke use() on all global variables to prevent
some linkers from deleting these otherwise unused symbols.
