Log:
  Pull in r219512 from upstream llvm trunk (by Hal Finkel):

[MiSched] Fix a logic error in tryPressure()

Fixes a logic error in the MachineScheduler found by Steve Montgomery
(and confirmed by Andy). This has gone unfixed for months because the
fix has been found to introduce some small performance regressions.
However, Andy has recommended that, at this point, we fix this to
avoid further dependence on the incorrect behavior (and then
follow-up separately on any regressions), and I agree.

Fixes PR18883.

  This fixes a possible "ran out of registers" error when compiling
  www/firefox 45.0 on i386.

  Direct commit to stable/9, because head already has this fix since the
  llvm/clang 3.6.0 import.

  PR:   207837

Changes:
  stable/9/contrib/llvm/lib/CodeGen/MachineScheduler.cpp

OPTIMIZED_CFLAGS is enabled by default. It doesn't pass just -O3 but also
--enable-optimize which lets vendor decide whether to pass -fomit-frame-pointer
and (in later versions) rust -O.

Strangely, I tried building www/firefox on stable/10, from before r410973 was
applied, and it builds just fine for me, even the problematic
Unified_cpp_protocol_websocket0.cpp file.  I'm unsure what is different in my
environment from the original submitter, though.  This is on pretty plain
stable/10 r294049, as of 2016-01-21.

$ make config -C /usr/ports/www/firefox


I'll add a workaround later via USES=compiler:c++14-lang.

I tried adding OPTIMIZED_CFLAGS=on to the make.conf for the poudriere jail

---Begin make.conf---
MACHINE=i386
MACHINE_ARCH=i386
ARCH=${MACHINE_ARCH}
USE_PACKAGE_DEPENDS=yes
BATCH=yes
WRKDIRPREFIX=/wrkdirs
PORTSDIR=/usr/ports
PACKAGES=/packages
DISTDIR=/distfiles
 /usr/local/etc/poudriere.d/RELENG_10_2_i386-make.conf 
WITH_PKGNG=yes
WITH_GALLIUM="yes"
DEFAULT_VERSIONS=apache=2.2 php=5.6
OPTIMIZED_CFLAGS=on

still fails

full log:
