[PATCH] PR30391: GIMPLE_MODIFY_STMT vs. middle-end

[François-Xavier Coudert]

Hi Roger,

Thanks for helping get rid of that regression that is blocking some
pretty used Fortran codes. I applied your patch today on a mainline
build on x86_64-linux, and re-built (without a full rebootstrap). I
get:

libbackend.a(tree-ssa-pre.o)(.text+0xab46): In function
`create_expression_by_pieces':
/utmp/coudert/gfortran/trunk/gcc/tree-ssa-pre.c:2637: undefined
