[LLVMdev] Dynamic Analysis
Dear John,
Now, I want to do dynamic analysis by dynamic slicing based on LLVM. I just
see that you have implemented dynamic slicing for LLVM. I also check the
Giri project, and I don't find the code. I hope I can learn something from
your code. I am very appreciated if you can tell me how to get the code or
send me one copy.
Thank you very much!

[Firefox] How to compile firefox with Clang for Linux
Hi All,
I am trying to build firefox with clang in Ubuntu 14.04 64bit. There is
always configure failed errors problem. I follow compiling firefox with
clang on linux
<https://developer.mozilla.org/en-US/docs/Compiling_Firefox_With_Clang_On_Linux>.
I add "export CC=clang export CXX=clang++" to mozconfig file.
I wonder whether you guys have built firefox with clang in Linux. Could

[PATCH] ept: Fix bug in changeset 22526:7a5ee3800417
This fixes a bug in changeset 22526:7a5ee3800417, where the wrong
value is read when deciding whether to flush the VTd tables. The
effect is minor: in situations where the p2m entry is changed but the
mfn is the same, the VTd tables will be unnecessarily flushed.
old_entry is left untouched in the second case, since having a present
old_entry will cause the an unnecessary check to be taken at

I can't find any benefit unrolling this loop.

Hi, you need to run some optimization passes first. (like -O2)

[LLVMdev] Loop-Unroll optimization
Hi,
You might want to try running -loops -loop-simplify before loop unroll.
>From loop simplify.cpp
This pass performs several transformations to transform natural loops
into a00011 // simpler form, which makes subsequent analyses and
transformations simpler and00012 // more effective.

You mean like

But still i am not able to observe any effect on bit code by running
*opt-2.8 -loop-unroll Hello.bc -o Hello_unroll.bc*

Changes since v1:
- Removed libxl vncviewer related dependencies
- The vncviewer function was modified to accept a domid instead of domspec;
- main_vncviewer was updated to reflect the new use.
- A domain_create structure is now passed to the parse_config_data where required/feasible (NULL otherwise)
- xl restore now have long options for vncviewer/vncviewer-autopass; docs updated.

1. You should run the passes in the same opt command, for passes like loops
which is an analysis pass provides results to the following passes.
2. You can pass a -debug flag to opt to see the some debugging info.
3. I tried this
opt -mem2reg -loops -loopsimplify -loop-unroll -unroll-count=3 -debug
loop.o -o tt.bc
and got this message.

Floating point semantic modes
> ... math errno ...
I wouldn't recommend to anyone that they should rely on math errno (because I don't trust libraries to correctly support it). My goal here was to incorporate our existing support for it into the rest of what I'm trying to document.
My understanding is that for clang this primarily controls whether or not we feel free to substitute intrinsics for recognized

Floating point semantic modes
Yes, you’re probably right about this. I was originally thinking of FENV_ACCESS as a fully strict mode of operation, but what you’re suggesting aligns with what Cameron suggested and even some of my own reasoning on other points. So, let me amend my previous proposal to say:
STDC FENV_ACCESS {ON|OFF}
Patch in progress. I think ON should force the following:

the items below or are some of them features that are known to be
missing in the xen release?

This error happened when I used xen-4.0.1-rc5 and kernel-2.6.31.13. Today
I update to xen-4.0.1 and kernel-2.6.32.25, it is with the same wrong.
