Date:   Fri Jul 28 22:23:05 UTC 2017

Modified Files:
src/external/gpl3/gcc/dist/gcc/config/i386: i386.c

Log Message:
Apply upstream patch:
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.

Log Message:
If -march=native is specified, only enable AVX if the processor supports
  it and the OS has enabled XGETBV for application use.
It might need to also check XCR0[2] (having executed XGETBV) to check that
  the kernel actually supports saving the YMM registers, but I suspect the
  kernel might defer setting that until the first fault.
See vol 1 section 13.5 of the Intel SDM (intel_x86_325462.pdf).

PR 46978: ICE on spilling MMX registers

GCC/i386 has code to lower the required alignment for long long to 32bit
as the CPU doesn't need more. It is also using the same mode for setting
up the MMX registers and in turn, the stack slots reserved for spilling
require 32bit alignment. The actual vector types used keep the original
64bit alignment, so when the compiler wants to spill a MMX register, it
hits an assertion. Fix this by using the vector type as raw type for MMX
registers.

netbsd64.h

Log Message:
Fix GCC to correctly implement the i386 psABI on NetBSD.
This consists of two parts:
- for NetBSD/i386 and NetBSD/AMD64 with -m32, use a default stack
  alignment of 23bit as specified by the ABI
- ensure that double and long long variables on the stack are by default
  only aligned to 32bit, if there is nothing else in the function
  needing a larger stack alignment

The combination ensures that SSE variables on the stack trigger the
realignment logic, but just using double or long long doesn't.
