Hi,
This patch restarts the series for introducing Pointer Bounds Checker
instrumentation and supporting Intel Memory Protection Extension (MPX)
technology. Detailed description is on GCC Wiki page:
http://gcc.gnu.org/wiki/Intel%20MPX%20support%20in%20the%20GCC%20compiler.
The first patch introduces pointer bounds type and mode. It was approved
earlier for 4.9 and had no significant changes since then. I'll assume patch
is OK if no objections arise.
Patch was bootstrapped and tested for linux-x86_64.
Thanks,
Ilya
