Subject: Add test case for symbol menu for local enumerators
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=acd6125f01dc9ba76423b7062c26ca16562943cf;p=binutils-gdb.git

Add test case for symbol menu for local enumerators

Ada will normally present a menu to the user to allow manual
disambiguation of symbols.  The AdaCore internal GDB had a bug that
prevented this from happening.  Although this bug is not in the FSF
GDB, it seemed worthwhile to write a test case to ensure this.
