similar to: [LLVMdev] Creating an LLVM backend for a very small stack machine

Hi Wesley, I've done quite a lot of work on register allocation for stack machines. You might want to look at my papers: http://www.dcs.gla.ac.uk/~marks/euroforth.pdf http://www.dcs.gla.ac.uk/~marks/thesis.pdf Good luck, Mark. -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu on behalf of Wesley J.

What problems did you have? Haven't done that, and I don't think there are any existing backends like this. It should be feasible, though; the backend code is pretty flexible. > * What

Wesley, Regarding access to the source code; I would send you the code, but I might be stepping on a few toes. The person to speak to is Chris Bailey at the University of York (in the UK). However it is written for the lcc tree-based IR, rather than the SSA-based IR of LLVM, so I don't think it will be that much use. A lot of the analysis it does is to find information that is explicit in

Since the Kalescope tutorial is so amazingly easy to work through that it makes me jealous for a similar tutorial on the backend. But I'm definitely not complaining. =) > If you're targeting a stack machine, I'd

Hi. Le duodi 2 frimaire, an CCXIV, Wesley J. Landaker a ?crit?: > speexenc always crashes on amd64; here is an example, and lots of info: I tracked this bug a bit further than you. Here is the origin of the crash: op.packet = (unsigned char *)speex_header_to_packet(&header, (int*)&(op.bytes)); (from speexenc.c) op.bytes is a long, not an int, it is wrong to pass it as an int,

Hi All, I am busy using R to do some regression modelling and have been using plot(x,y,"") to visualise my variables. I would now like to label my points using data stored in the data.frame used for the regression analysis. For example each of my data points is made up of a field measured forest volume value and a remotely sensed vegetation estimate (NDVI). Each point is an enumeration

Hi, All, Suppose I have a CSV file, there is data in it. * Column 1 Column2 Column 3 Column 4 Row1 a b c Row2 a2 b2 c2* You know, the column 4 is no data Now, I would like to insert data to Column 4, after save, the CSV file will be: * Column 1

I have an OpenLDAP backend, Samba knows how to talk to it, my Samba users are stored in LDAP and file shares work fine authenticating to the LDAP server. I tried executing smbldap-useradd -w server02 on the command-line and got the following error: failed to perform search; Can't contact LDAP server at /usr/lib/perl5/vendor_perl/5.8.7/smbldap_tools.pm line 362, <DATA> line 283.

Dear All I want to store matrix in an array Suppose s<-array(0,4) for(i in 1:4) s[i] <- read_matrix(a,2,2) But the error - number of items to replace is not a multiple of replacement length. Can you suggest me any alternative method for storing a matrix in an array. Thanks In advance. Kind Regards Wesley C Mathew [[alternative HTML version deleted]]

Is it possible to specify aliases for the username, so that a user can choose any 1 of several names to log in with? Like let's say we have my name as a username, "Wesley". But what I if I want to be very lazy and only sign in with "wes"? And I would like to have the option of using either. And if I change any attribute of one alias, it's all stored in the same place,

Dear All Subject : Multiple Lines in Graph Could you please help me to draw two lines in a graph. plot(f1, t1, type ="b") and plot(f2,t2, type="b") where t1, t2, f1,and f2 are single dimensional matrix. I have these two graph. How can I draw these two lines in a single window? Thanks in advance Kind Regards Wesley C Mathew [[alternative HTML version deleted]]

Dear All I was trying to install R-2.10.0-2.fc11.X86 in Fedora-13-i386 but it makes error. Could you please tell me which is the exact version of R for Fedora 13. Thanks in advance Kind Regards Wesley [[alternative HTML version deleted]]

Right now you can use either Pens/Balance/Pound to put in front of some Mongrels and it works really good (easy to setup too!). I got to thinking, would it be possible to mimic what Pens/Balance/Pound does in pure Ruby (yeah, I know the answer is yes)? I guess I''m looking for a starting point. Does one simply write an HTTP listener that then redirects the calls to Mongrel? Is

Is it kosher to include vim mode line comments inside of LLVM source files? I would like to do this inside of the MicroBlaze backend to ensure that tabs are expanded into exactly two spaces. I see that right now the following files have these vim mode line comments: include/llvm/ADT/SetVector.h lib/Archive/ArchiveInternals.h lib/Linker/LinkModules.cpp lib/Transforms/IPO/DeadTypeElimination.cpp
