[PATCH] Fix libmudflap.c++/pass57-frag.cxx

[Jakub Jelinek]

Hi!

Richard changed 4 days ago TARGET_MEM_REF representation, the offset
now uses some pointer type for offsets on the constants instead of
sizetype.
The following patch makes sure we don't create invalid
PLUS_EXPR with sizetype first operand and result, but pointer type
INTEGER_CST as second argument.

Bootstrapped/regtested on x86_64-linux and i686-linux, committing as
obvious.
