Re: Value range propagation pass in 4.0.1 RC1 (or not)

[nkavv at physics dot auth dot gr]

Dear Diego,

is the newest version of your pass (including the June 01 modifications at
gcc-patches) applicable to all statements in a basic block and not only to the
conditionals?

I mean, i saw the gcc-4.0.0 release version (VRP in tree-ssa-dom.c). In this
version two things happen:

a. -fdump-tree-vrp not applicable
b. VRP applied only to variables in conditional statements
