for ansi.h on netbsd.
gcc{7,8}: document same patch that already existed was upstreamed.
This patch is necessary to build GCC on NetBSD >= 9.0, since changes
to ansi.h resulted in not using the same include guards.
Fixes PR toolchain/54362
* Port from NetBSD src
Fix __stack_chk_fail_local undefined reference error
from "gcc test.c -fstack-protector-all -fPIE".
* As a result, pkgsrc/www/firefox build under NetBSD/i386 7.1 is fixed
Incorrect codegen from rdseed intrinsic use (CVE-2017-11671)
We should not expand call arguments in between flags reg setting and
flags reg using instructions, as it may expand with flags reg
clobbering insn (ADD in this case).
Attached patch moves expansion out of the link. Also, change
zero-extension to non-flags reg clobbering sequence in case we perform
zero-extension with and.

Changes, New Features, and Fixes in GCC 4.9 can be found here:
https://gcc.gnu.org/gcc-4.9/changes.html
This is based heavily on lang/gcc47 but updated for GCC 4.9.1. Tested on
SmartOS (32-bit and 64-bit) and NetBSD 6.1.4/amd64.
