similar to: [LLVMdev] llc c backend can produce code that doesn't compile on gcc 4.x

The C backend can currently (recent head) produce code with such patterns: /* Global Declarations */ /* Structure forward decls */ struct l_structtype_s; /* Typedefs */ typedef struct l_structtype_s l_fixarray_array3[3]; /* problematic declaration */ typedef struct l_structtype_s l_structtype_s; /* Structure contents */ struct l_structtype_s { int field0; }; gcc 4.0.1 will reject this with

The structure contents are defined right afterwards, but I assume that

It seems very similar to http://llvm.org/bugs/show_bug.cgi?id=737 . You might want to check if it's the same problem. If not, then please create a new bug report. -bw On 9/20/06, Samuele Pedroni <pedronis at strakt.com> wrote: > The C backend can currently (recent head) produce code with such patterns: > > /* Global Declarations */ > /* Structure forward decls */ >

Hello, Simply put, I'm trying to call a function "testme" with value "age=NA". I wish to use "dotlist<-list(...)" inside the function and have dotlist become: $age [1] NA I'm modifying existing code and need to minimize changing that code so it's easiest to conform how I call the existing function. My sample code fragment, results, and R.version

To all. I need your help. The big question is: How do I make an R library with Fortran 95 files? You may assume that I am a pretty decent programmer in both R and Fortran. I lay out a scenario and need your help! I know how to make an ordinary R package and have dabbled with R + Fortran 95 *.dll linking. I do not have a great handle on the whole Makevars file and whatever else I might need

You are right, the machine I am on is a AMD Opteron. I could probably generate working code for x86, but I am testing the implications of using 64 bits integers. The four weeks is not really important, it's just that it would be nice to have really fast code to showcase. Something related to this: to test the effect of 64 bits integers I replace all reference of int by long in my .ll file.

Hi, For the PyPy project ( http://codespeak.net/pypy ) I am working on the x64-64 support. I would like to use llc -march=ia64 to generate the assembly but that is not supported at the moment. As a workaround I let llc generate C code that gets compiled, but this unfortunately is not a good way to show the power of llvm. A understood this ia64 support will be worked on soon. First week of july

Can you use exported virtual resources with custom definitions? As an example, with the following definition: define vr-tester() { file { "/tmp/vr-success.txt": content => ''foobar''; } } this code is working for me: class testme { @vr-tester { "foobar": ; } Vr-tester <||> } but this is not: class testme {

hello everyone, I few days ago I had some code (for the PyPy project) that llc - march=c converted to a switch statement and gcc compiled that nicely to a jumptable in the .s file. Now I try to reproduce when directly going from a .ll to a .s file. But I now see a long list of compare and jumps instead of the jumptable. Is there a transformation that does this if->switch(ing) or is

Hello. I've got a problem logging in to a Sparc Solaris 10 machine with public key authentication. I searched, and found a similar problem report at <http://thread.gmane.org/gmane.network.openssh.devel/12694>. For that guy, the problem had to do with LDAP. My user accounts are also stored in LDAP, an OpenLDAP server, to be exact. That server runs on the same machine as the machine

Hi there, The IA64 architecture, which had its 'official' name changed to the "Itanium Processor Architecture", *is* supported by llc. I am pretty sure you are talking about the x86-64 architecture, which has also had its share of unfortunate name changes and is also known as "AMD64", "EM64T" and all sorts of things in between. x86-64 is *not* currently

I'm trying to write a formula method for canonical correlation analysis, that could be called similarly to lm() for a multivariate response: cancor(cbind(y1,y2,y3) ~ x1+x2+x3+x4, data=, ...) or perhaps more naturally, cancor(cbind(y1,y2,y3) ~ cbind(x1,x2,x3,x4), data=, ...) I've adapted the code from lm() to my case, but in this situation, it doesn't make sense to include an
