function call replacement
Hi,
Thanks both of you for the help. I just missed that Create function had
many optional arguments... sorry for that. However my problem wasn't coming
from here (IRBuilder CreateCall function still return a pointer to CallInst
so I just added 2 times the call?). I didn't wanted to detail the all issue
previously because I knew I had a problem with my syntax. So here's my
problem:

[LLVMdev] problem with replacing an instruction
I am trying to change this

noalias %arg2) {
entrypoint:
%0 = bitcast float* %arg1 to <4 x float>*
intothis
define void @main(float* noalias %arg0, float* noalias %arg1, float*

Create new string of same length as entry in dataframe
I suspect that this is simple, but thanks in advance for any advice...
I have a dataframe, t2:
V1 V2
aaa 3
aaaa 4
aaaaaa 6
a 1
aa 2
V2 is the length of the string in V1 using nchar(as.character(t1$V1))
I'd like to create a third column, that contains a string of the length of
V2, but containing an alternate text, e.g.
V1 V2 V3

Copy Function from one LLVM IR file to another
Hello everyone,
I wanted to copy a function from one file to another. The file that I
wanted to copy the function into contains a function with the same name and
same number of instructions. I decided to just replace the instructions
with those of the other function. I am doing all of this from within a
function pass.
*1.* I created a function pass in which I extract a function using

[LLVMdev] Replacing instruction in LLVM IR by an intrinsics
Hi everyone,
I am trying to write a pass, that finds some instructions and replaces them with my intrinsics,
but I am having problem understanding, how this should be done.
Let's say I have this instruction:
%tmp14 = load i32* getelementptr ([32 x i32]* @gpregs, i32 0, i64 28)
and i need to read the load's operands and replace it by let's say:
%tmp14 = call i32

[LLVMdev] ReplaceInstWithInst appears to invalidate BB iterator?
Hello,
I have a call to ReplaceInstWithInst(Instruction *From, Instruction *To) inside of a for loop iterating through a BasicBlock::iterator. On the very next pass after I replace the instruction, the iterator appears to be invalidated. Is this supposed to happen or am I doing something silly? Is there a more appropriate way to do this? Thanks,

function call replacement
Hi everyone,
I am trying to replace the call of a certain function with a call to
another function. It would for example replace the following:
%call = tail call noalias i8* @func(i64 10)
by
%call = tail call noalias i8* @other_func(i64 10)
I managed to declare other_func correctly but I am having troubles to
understand how I should proceed to do the replacement.
I tried to use

[LLVMdev] ReplaceInstWithInst problem
Hi,
In my source code, I have the following declaration char a[30];
When I'm running the following (Assuming that I is an instruction pointer pointing to the instruction to be replaced, i.e. %a = alloca [30 x i8], align 1):
ArrayType* arr = ArrayType::get(IntegerType::get(getGlobalContext(), 8), 10);
AllocaInst* pa = new AllocaInst(arr, "blah");
BasicBlock::iterator ii(*I);

lattice x(y)lab and expression
Another question about lattice:
Is there a way to use plotmath in the labels and strips?
E.g.
xyplot(y~x|group,data=test.df,
panel=function(x,y,subscripts,df) {
llines(x,y,col="black",lwd=2)
llines(x,df[subscripts,"lowerCI"],lty=2,col="#aaaaaa")
llines(x,df[subscripts,"upperCI"],lty=2,col="#aaaaaa")
},

Samba and Password Complexity
A password set from Windows XP requires a certain level of complexity:
by default, Windows will not allow a password of "aaaaaa", but it will
allow "Johnny1". I've been experimenting with a check password script
so that both would be rejected. That worked. However, when I removed
the check password script line from smb.conf and restarted Samba,
Windows did not return to

GlusterFS, move files, Samba ACL...
[ Received no feedback, i resend it... ]
A little strange things, but i'm hitting my head on the wall...
I needed to 'enlarge' my main filesystem (XFS backed-up), that contain my
main samba share and a brick for a GFS share; i've setup a new volume (for
the VM), formatted XFS, move all the file taking care to umount and stop GFS
(so, syncing the brick, not the GFS filesystem)

[LLVMdev] Strange error using CallInst constructor
Please keep replies on the list.
Now you've missed "InputIterator must be a random-access iterator
pointing to contiguous storage (e.g. a std::vector<>::iterator).
Checks are made for random-accessness but not for contiguous storage
as that would incur runtime overhead." from CallInst's constructor
(although that comment should be on Create()). Function::arg_iterator

Orphaned rsync process on remote machine?
All,
Sometimes when I do an rsync, it times out and leaves on orphaned
process on the remote machine. I am running rsync over ssh using
public key authentication. I synchronize about twenty-five machines,
and this problem only appears on one of them. It worked until
recently on this machine. I don't know what changed or what is
different.
I run rsync with a command line like this

Not quite, it's packet "real, real, imag, real, imag, ...".
