Subtarget Initialization in <ARCH>TargetMachine constructor
...an MCSubtargetInfo rather than a subclass of Subtarget.
The following is what I observed:
Both Subtarget constructor and initAsmInfo will eventually create
a MCSubtargetInfo, which calls InitMCProcessorInfo.
void MCSubtargetInfo::InitMCProcessorInfo(StringRef CPU, StringRef FS) {
FeatureBits = getFeatures(CPU, FS, ProcDesc, ProcFeatures);
if (!CPU.empty())
CPUSchedModel = &getSchedModelForCPU(CPU);
else
CPUSchedModel = &MCSchedModel::GetDefaultSchedModel();
}

Performance degradation on ARMv7 (cortex-a9)
...e
ProcA9 features appear in /ARMFeatureKV/ table:
/{ "a9", "Cortex-A9 ARM processors", { ARM::ProcA9 }, {
*ARM::FeatureFP16* } },
/With your change, the features for ProcA9 in the above entry are
empty.//This ARMFeatureKV table is then read in MC/MCSubtargetInfo.cpp
in the getFeatures() function.
Thanks,

Re: [nut-commits] svn commit r801 - in branches/megatec-usb: . drivers
Hi Alexander,
thanks for your good work on the megatec_usb driver. I have made a few
more (cosmetic) changes.
Is the driver now working stably for your device? In particular, do
the instant commands (and particularly "upsdrvctl -k") work properly?
In this case, we could hopefully mark the device as "supported" and
merge the driver to the main branch.
There is still the

Subtarget Initialization in <ARCH>TargetMachine constructor
Hi,
I found some different discrepancy on how Subtarget is created
between some arch specific TargetMachine constructor.
For example, for BPF/Lanai:

StringRef CPU, StringRef FS,
const TargetOptions &Options,

architecture-specific stuff in xend
Hi Ewan, I''m almost ready to integrate some PPC-specific stuff into
xend, and I was wondering if you had a plan for how that should work.
First example: the device tree data structure we talked about a few
weeks ago. We will need to pass the config data to PPC code, probably in
XendDomainInfo.initDomain(), and then pass the resulting data structure
into libxc''s xc_linux_load()

Performance degradation on ARMv7 (cortex-a9)
Hi Bradley,
I was doing some performance analysis for ARMv7 (cortex-a9) and I
noticed that one of my benchmarks degraded by 93%. I have tracked the
regression down to the following commit by you:

[PATCH nbdkit UNFINISHED] Add the ability to write plugins in golang.
Sorry Dan, but I really do dislike golang with a passion :-)
Here is a patch that allows you to write nbdkit plugins in golang. As
with C, OCaml and Rust, you can write a plugin in Go which compiles
directly to a .so file that can be loaded into golang, so in that
sense it works completely differently from scripting language plugins
like Perl and Python where there's an
