Buildbots timing out on full builds
Hi,
We've noticed that recently some of our bots (mostly
clang-cmake-armv7-a15 and clang-cmake-thumbv7-a15) started timing out
whenever someone commits a change to TableGen:

With vmul+vadd instruction pair comes extra overhead of load/store ops, as
seen in assembly generated. With -mcpu=cortex-a15 option clang performs
better, as it emits vmla instructions.

the benchmark you're tuning to, you'll never see it. It may be that the
cost is small and that we decide to pay the price, but not until we know
that the cost is.

[ANNOUNCE] Xen port to Cortex-A15 / ARMv7 with virt extensions
Hi all,
a few weeks ago I (and a few others) started hacking on a
proof-of-concept hypervisor port to Cortex-A15 which uses and requires
ARMv7 virtualization extensions. The intention of this work was to find
out how to best support ARM v7+ on Xen. See
http://old-list-archives.xen.org/archives/html/xen-arm/2011-09/msg00013.html
for more details.

[LLVMdev] ARM assembler bug on LLVM 3.5
...;t work with clang. clang reports
error on the sdiv instruction in the assembler.
The problem is this - you either compile this program with
-mcpu=cortex-a9, then clang reports error on the sdiv instruction because
cortex a9 doesn't have sdiv. Or - you compile the program with
-mcpu=cortex-a15, then clang compiles it, but it uses full cortex-a15
instruction set and the program crashes on cortex a9 and earlier cores.
Even if I use -no-integrated-as (as suggested in bug 18864), clang still
examines the string in "asm" statement and reports an error. GCC doesn't
examine th...
