r242278 - /branches/ARM/sve-branch/gcc/combine.c


Author: rsandifo

New Revision: 242278

Log:
Prevent invalid register mode changes in combine

This patch stops combine from changing the mode of an
existing register in-place if doing so would change the
size of the underlying register allocation size, as given
by REGMODE_NATURAL_SIZE.  Without this, many tests fail in
adjust_reg_mode after SVE is added.  One example is
gcc.c-torture/compile/20090401-1.c
