> FAIL: gcc.dg/tree-ssa/pr88367.c
REGRESSION: Andrew
RVRP is deleting a call to bar() inside of foo() and causing a
regression.
Apparently objects can live at address 0 and there is some new
code to avoid deleting NULL pointer checks with
-fno-delete-null-pointer-checks. I think the ranger must be
taught this. I already ported Jakub's VRP code to range-ops,
but there is some vr-values stuff that I think must
analogously done in the ranger.
See patch at:

> FAIL: gcc.dg/uninit-pred-6_c.c
Expected. Long-standing regression in our branch. Jeff has
mentioned he has a work-in-progress to fix this.

The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
