But it still caused a few regressions on x32 branch: FAIL: gcc.target/i386/pr45670.c scan-assembler-not lea[lq] FAIL: gfortran.dg/character_array_constructor_1.f90 -O1 (internal compiler error) FAIL: gfortran.dg/character_array_constructor_1.f90 -O1 (test for excess errors) FAIL: gfortran.dg/cshift_large_1.f90 -Os (internal compiler error) FAIL: gfortran.dg/cshift_large_1.f90 -Os (test for excess errors) FAIL: gfortran.dg/eoshift_large_1.f90 -Os (internal compiler error) FAIL: gfortran.dg/eoshift_large_1.f90 -Os (test for excess errors)
