------- Comment #6 from dominiq at lps dot ens dot fr 2010-08-07 09:01 ------- It turns out that the test in comment #0 was not fixed by the patch in comment #5, but by revision 162966. However with the slight change
a(4:23:3) = a(4:22:3) a temporary is still created. The patch in comment #5 avoid temporaries in situations such as a(4:19:3) = a(7:22:3) a(4:20:3) = a(7:22:3) a(4:19:3) = a(7:23:3) nl = 4 nu = 20 a(1:16:3) = a(4:nu:3) a(1:16:3) = a(nl:20:3) but not for a(1:16:3) = a(nl:nu:3) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44235
