New Revision: 257234
URL: https://gcc.gnu.org/viewcvs?rev=257234&root=gcc&view=rev
Log:
Use pointer sized array indices.
Using pointer sized variables (e.g. size_t / ptrdiff_t) when the
variables are used as array indices allows accessing larger arrays,
and can be a slight performance improvement due to no need for sign or
zero extending, or masking.
Regtested on x86_64-pc-linux-gnu.
