[LLVMdev] LLVA and WCET Analysis
Hello everybody,
I'm curious whether there have been any attempts to perform
performance analysis on the LLVA level. I am interested in the
derivation of flow-facts (loop bounds etc. - what about the
value-range-propagation pass I read about on this list some time ago)
but even more I am interested in exec-time modeling (how long does it
take to execute a bunch of LLVA instructions on

If you are asking about LLVA not LLVM, see
http://llvm.org/pubs/2006-06-18-WIOSCA-LLVAOS.html
LLVA specifically is refering to a research project offshoot of llvm.
LLVM instructions do not have 1:1 mappings to native instructions
(sometimes multiple llvm instructions map to fewer native insts,
sometimes the other way around).

[LLVMdev] Would it be possible to have the LLVM be seen as an arch for the kernel to compile against?
I posted this question on the llvm channel on irc. I am new to all of
this. And I only found out about LLVA as a result of the irc. And please
forgive my erroneous terminology. So let me try this as best I can.
I want to know if the code of LLVA/LLVM can be used as a virtual
processor in configuring the linux kernel? Maybe you have already
encountered this and possibly accomplished it as

[LLVMdev] Virtual OS
Hi,
I have been away from the list for a while, so do apologize in advance if
the topic is slightly off topic here.
I have started a hobby project to create a virtual OS library (jos). The idea was to create a set of C API's for operating system specific tasks
i.e. File IO, threading and etc. For example:
typedef jos_handle jos_thread;
jos_thread jos_thread_create(...);

[LLVMdev] Problem of running data structure analysis (DSA) on Linux kernel
Hi,
I ran into a problem when running DSA on Linux kernel (the Kernel
version I used is
2.4.31). The analysis was aborted when it tried to do
DSNode::mergeTypeInfo on some data structure in the kernel. I have
filed a bug report at http://llvm.org/bugs/show_bug.cgi?id=1656.
My question is what version of Linux kernel LLVM has been tested on
successfully? To run DSA analysis, should I use the

[LLVMdev] LLVM and newlib progress
I managed to compile newlib with llvm-gcc yesterday. That
is, the machine independent part is now basically done, and
the syscall part contains no-op stubs provided by libgloss.
I haven't tested the port yet, but since newlib has already
been ported to many architectures, I would be pretty surprised
if there were any major problems.
A couple of things I noticed when configuring newlib for
