[Mesa-dev] [PATCH 2/4] glsl: make ast_node destructor virtual

[Rob Herring]

Make ast_node destructor virtual to fix the following clang warning:

src/compiler/glsl/ast.h:51:4: warning: destructor called on non-final 'ast_node' that has virtual functions but non-virtual destructor [-Wdelete-non-virtual-dtor]
