Dear friends, I have been using the SUIF Machine infrastructure for sometime. Some optimizations are available without using a target machine, i.e. at the SUIFvm level. At this level you have "infinite" registers. Other optimizations, including analyses as for profiling require the use of a target library, a complete backend...

...tectures is described in the "A Generalized Algorithm for Graph-Coloring Register Allocation" by Michael D. Smith, Norman Ramsey and Glenn Holloway: http://www.eecs.harvard.edu/~nr/pubs/gcra-abstract.html There exists also an implementation of the algorithm described in the paper for the SUIF compiler suite. I was planning to port it to LLVM, but a bit later. At the moment I'm working on the implementation of a linear scan register allocator based on the Wimmer's paper "Linear Scan Register Allocation for the Java HotSpot Client Compiler": http://www.ssw.uni-linz.ac...

i don't know the status of nci, but suif/suif2 development and publication is very active. it's will be great if there are tools to transform llvm ir and suif ir to each other. acutally, i didn't use suif but llvm just because suif cannot be compiled by visual studio.net (but visual studio 6).

national compiler infrastructure - http://www.cs.virginia.edu/nci/ is there any on-going efforts to integrate llvm with other nci projects?

Hi All, I wanted to know if LLVM is capable to do source code analysis as SUIF does. What I am looking for is parsing the entire program and classifying each line into memory access, assignment statement,etc. SUIF has an implementation where we can pass through the entire source code and look for such statement for our analysis. Could you please send me a link if this possib...

Hi All, I think , I was unclear in my last post. I am looking for source code analysis of a program, something similar to what SUIF does. Consider a simple example of Matrix addition A[i][j]+=B[i][j]; I want to know how matrix A is accessed, like whether it is A[i][j] in this case or A[j][i]. Is there anyway in llvm to write a pass to identify this? Can someone give pointers to it? Regards, Kamal

...:-) > > -bw Hi Bill i would like to have a look to your register allocator. Is it on LLVM SVN? Or is it something standalone? BTW, my time is limited right now (writing up my Ph.D. as well as a processor soft core) but i will dedicate some time (after all i do this for polishing my Machine-SUIF passes, and there is no help there). LLVM has a community, really working on advancing the compiler. Nikolaos Kavvadias
