You are, and it shows some bugs even. gimple_lcx is obviously destroyed
by expand, and I find it unlikely that no pass ever introduces a
critical edge...
But the diagram shows gimple_lcx stopping at expand but continuing its
lifetime through RTL passes (so gimple_lcx according to the diagram is
_not_ destroyed by expand). So, I am left wondering if the bug is in the
diagram or GCC.
It shows bugs in GCC's pass description, to be clear.
