Re: [PATCH][2 of 2] RTL expansion for zero sign extension elimination with VRP

[Kugan Vivekanandarajah]

Hi,

This is the updated patch for expanding gimple stmts without zer/sign
extensions when it is safe to do that. This is based on the
 latest changes to propagating value range information to SSA_NAMEs
and addresses review comments from Eric.

Bootstrapped and regtested on x86_64-unknown-linux-gnu and arm-none
linux-gnueabi. Is this OK ?

Thanks,
Kugan
