[PATCH] Fix bootstrap failure (with g++ 4.8.5) in tree-if-conv.cc.

[Roger Sayle]

 

This patch fixes the bootstrap failure I'm seeing using gcc 4.8.5 as

the host compiler.  Ok for mainline?  [I might be missing something]

        * tree-if-conv.cc (predicate_scalar_phi): Make the arguments

        to the std::sort comparison lambda function const.

 

 

Cheers,

Roger
