--- Comment #39 from Richard Biener <rguenth at gcc dot gnu.org> ---
For the second largest LTRANS unit we also have
tree SSA incremental : 10.89 ( 10%) 0.02 ( 3%) 10.74 ( 10%)
5030k ( 1%)
tree loop unswitching : 1.39 ( 1%) 0.00 ( 0%) 1.39 ( 1%)
8332k ( 2%)
`- tree SSA incremental : 9.58 ( 9%) 0.01 ( 1%) 9.53 ( 9%)
0 ( 0%)
showing that almost all update_ssa load is from the unswitching pass which
updates SSA form for each unswitching. One should be able to delay that
until we want to process an outer loop, should be much easier after the
pending rewrite.
