While beginning to add vector registers to a back end I came across the following problem: as soon as I define two sets of registers that have a many-to-one mapping the live interval pass appears to double- kill the mapped-onto register. I have the following excerpts from my RegisterInfo.td. def V4R0 : R4v<0 , "V4R0 ", []>, DwarfRegNum<0>; def R0 : Rg<0 ,

At least or Mips, this line seems extraneous. I removed it and and all consequential uses of that (400 changes to MipsRegisterInfo.td) and make check for mips still works. Am running our full test sequence now. This Mips part of this was copied from the Sparc port. Similar problems in other ports. Seems this has just been copied many times to new ports.

The field Num seems to have no meaning. It is not recognized by the backend tools. It does not hurt anything but should not be there. // We have banks of 32 registers each. class MipsReg<string n> : Register<n> { field bits<5> Num; let Namespace = "Mips"; } class ARMReg<bits<4> num, string n, list<Register> subregs = []> : Register<n> {

Hi Chris, Here's the fix: Index: SparcRegisterInfo.cpp =================================================================== --- SparcRegisterInfo.cpp (revision 700) +++

People, I''m trying to run the ruby debugger against a Test::Unit::TestCase class which is a parent of a Rails class. I started my study with a simple script: # # bikle_test.rb # require ''test/unit'' class BikleTest < Test::Unit::TestCase def setup @string10 = "hello" end def test10 assert_equal @string10, "hello" end end The

Hi all, Is there a pass that computes livein information for each MachineBasicBlock? I tried to find such a pass but could not find any. I am trying to use the livein information to get dead registers to insert some instructions right before code emission but the livein information seems to be invalidated by some pass. I might need to recompute the livein information before my pass. Thanks a

While migrating my codebase from llvm-2.6 to llvm-2.7, I found a different behaviour in the register allocation. I have been able to reproduce it using the msp430 backend, with the 2.7 release as well as the svn head. For the msp430, the first four parameters of a function are passed thru registers. What I observe is that if those parameters are not used inside the function, those registers can

Hello, I have 2700 text files in a folder and need to apply the same program/procedure to each individually. I'm trying to find how to code something like: For each file in <Folder> do {<Procedure>} is there an easy way to do this? other suggestions? I have tried to list all the files names in a vector e.g. >listfiles[1:10,1] 1 H:/Rtest/AXP.txt 2 H:/Rtest/BA.txt 3

I would like to maintain the livein information for physical registers on basic blocks past register allocation, or recreate it if possible. The goal is to be able to run a late pass of DeadMachineInstrElim, which requires valid livein information. The X86 target returns false for requiresRegisterScavenging so passes like BranchFolding don't update the livein information. At that point I

Hi Guys, I am new to R and just trying to write a small script to automate a couple commands. But I run into the setwd(): cannot change working directory. I googled a little bit and tried all fixes/suggestions with no success. Basically I have a script that works from inside a directory with my data (/home/sean/Rtest/Data01). Now I want to modify the script to make it run from the upper directory

Hi, I have been developing a small package. It install under RedHat Linux 9.0 without a problem. However, I have a small problem under Windows XP. I am using R-1.8.0 on both systems and HTML Help Workshop 4.74.8702.0 on Windows XP. I created the package under Linux. When I try to install the package created under Linux in Windows XP using c:\rtest> rcmd install rtest I get the following

I'm not looking for an answer here, this is just a report of a peculiar event I've observed and can reproduce. I'm developing a g95 (20050129) compiled package on windows xp pro using R-2.1.1, and gcc-3.4.2 (mingw special). An older version of the F95 package compiled and ran without problems. The new version of the package includes extensive changes in the code. The package has a

Hi, I am working at a major financial institution and we would like to embed R in one of our front office application. The application is written in C/C++ so I started by trying to compile the examples in "tests/Embedding" of R 2.0.1. I have modified "tests/Embedding/Makefile" according https://stat.ethz.ch/pipermail/r-help/2005-February/064341.html and set

Hi Tom, I'm pretty sure this function should only ever be called once, by SelectionDAG. Do you know where the second call is coming from in your code? Cheers, Lang.

Hi, I've been trying to install the statnet package on my Solaris 10/Intel system. I've been having problems with one of the dependencies, sna. During the compile, it always fails and complains about __builtin_isnan (please see below for output). I have tried installing this using Sun Studio 12, as well as gcc4 from opencsw.org. I am thinking it may have to do with what R thinks is the

Dear Team, Maybe somebody already tried to install mpfr and gsl packages for R on SLES. Exactly I try to install Rmpfr_0.6-1.tar.gz and gsl_1.9-10.3.tar.gz on SLES11 SP4. These are the available packages from official SLES SDK media: rtest:/home/ruser # rpm -qa | grep -i gsl gsl-devel-1.11-1.30 gsl-1.11-1.30 rtest:/home/ruser # As I understand gsl is from 1.11 till 1.30 level.

This patch seems to have been lost on the llvm-commits mailing list. Would someone be able to review it?
