Subject: Add query to determine whether a name was declared at this scope
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ac4fdc255ba82b96cc867f084f6b781d6e95136b;p=mesa.git

Add query to determine whether a name was declared at this scope

This will be used to prevent a variable and a function with the same
name from being declared.  As a side effect, the calls to
add_{type,name,function} should never fail.
