[cfe-dev] State of NaCl in monorepo?
Hi Fangrui,
As you noted we are working on helping our NaCl users transition to
WebAssembly and new web APIs that cover the functionality offered by NaCl.
In terms of actually turning down the platform features, we recently
announced a timeline at
https://blog.chromium.org/2020/01/moving-forward-from-chrome-apps.html.
In terms of LLM, I would prefer to kee...

State of NaCl in monorepo?
Hi all,
LLVM/Clang supports an OS called 'NaCl' (llvm/include/llvm/ADT/Triple.h).
It apparently hasn't had any development since 2015.
This page https://developer.chrome.com/native-client/migration
mentions that NaCl is deprecated.
Is it still used? If not, I would propose that we remove it.
I created a patch https://reviews.llvm.org/...

Row names and matrixs
...I was told my another well-versed R
programmer to use the follow script:
x<-as.matrix(test1[,-1]) ## skip column 1
rownames(x)<- test[1,]
heatmap(x, scale="none")
This was for data set up in 4 columns such as when you read the data in R it
looks like:
Loci Cont NaCl Peg
1 0231 2.1 4.2 4.1
2 1253 4.1 2.3 2.3
3 8167 5.7 1.1 3.4
Using the script above and this dataset it worked well - the Loci was used
as the row labels rather than the numbers assigned by R.
Looking at the data after this script...

Hi Jim,
This is a great question.

for the constant island pass. At this point for the NaCl platform we
disable this pass, generating instructions like movt instead (NaCl
requires at least v7 for ARM). However, as a future enhancement we'd
like to follow gcc's path and adjust the pass to coexist with
potential bundling by computing worst-case estimates for the sizes of

[LLVMdev] GSOC project on KCoFI
...to the community if I do the improvements number #1
and #3 mentioned in my previous mail to the mailing list or if i try to
port it to arm architecture?
I have decided to go ahead with the improvements #1 and #3 that are
improving the call graph and porting the KCoFI SFI methods to the ones used
in NaCl and PNaCl. It seems to me the community is more interested towards
the SFI methods.
If the course of the project permits I may also contribute to the fourth
improvement that you mentioned.
Earlier I mentioned three modifications to improve the KCoFI project.
After the valuable feedback from the me...

RFC: Removing the DataStreamer and MemoryObject interfaces
...of some refactorings I am making to BitstreamReader, I would like
to simplify it by changing it to use a memory buffer directly and then
removing the DataStreamer and MemoryObject interfaces.
My understanding that the only significant user of that interface as
designed (for network streaming) is PNaCl, however it looks like removing
this interface would not impose a significant burden on that project; they
are already maintaining a couple of forks of BitstreamReader [1] so it
would appear that the only change necessary on their side would be to also
fork the interfaces.

[LLVMdev] Building a stable bitcode format for PNaCl - based on LLVM IR
From the provided documentation I understood that in memory data
structures of a PNaCl program are incompatible to the host program
because ABIs are different (e.g. PNaCl pointers are always 32-bit even
when running on x86_64 platform).
So PNaCl program can't access any data structures of the host program
directly. The only communication way is by using syscalls, but the

Samba on Chrome OS
Chrome OS will soon be adding the chrome.fileSystemProvider[1] API,
which would enable the development of a Samba Chrome OS app when used
in conjunction with the chrome.sockets.* API or the networking APIs
provided by NaCl.
Is anyone on this list interested in porting or integrating Samba with
Chrome OS? If so, there are two routes we can take: a full JavaScript
port, or porting an existing C++ or Python implementation directly
with NaCl, which might be more performant and possibly less work.

[LLVMdev] Optimization on Atomics (and the OpenMP memory model)
Hi everyone,
The OpenMP standards committee has begun work to formalize their memory model, and define its relationship to the C/C++ memory models. A questionnaire has been put together (pasted below), and I'd like everyone's help in composing detailed answers to inform their decision-making process. While our OpenMP support is still in active development, many of these questions apply

[LLVMdev] Broken PLT on ARM from R183966
...made Fast ISel default. Unfortunately, Fast ISel is broken in terms of applying the ARMII::MO_PLT flags to calls in PIC mode (at least when emitting assembly); it never does this. The normal ISel pass handles this situation correctly so a temporary local change to disable FastISel for linux / NaCl targets is working for me right now.
I'm not very familiar with the ISel passes. I'm guessing the correct thing to do here would be to apply the attribute correctly in FastISel so it works, but I'm kind of unfamiliar with this part of the code and won't have time to dig into it ri...

[PATCH] curve25519-sha256@libssh.org key exchange proposal
...n 2006 by DJB [Curve25519]. Its main stengths are its
speed, its constant-time run time (and resistance against side-channel
attacks), and its lack of nebulous hard-coded constants.
The reference version being used in this document is the one described
in [Curve25519] as implemented in the library NaCl [NaCl].
I namespaced this method with @libssh.org since I implemented it first
in libssh and intent to release it with the next release.
In attachment, you will find a patch to openssh-6.3p1 (I think
adaptations for OpenSSH are trivial). It links to libnacl. However, my
autotools skills are lack...
