Hello, This patch fixes PR2218. However, I'm not pretty sure that this optimization should be in MemCpyOpt. I think that GVN is good place as well.

Hello, I fixed my patch as you asked. Sorry for the delay, I'd been working on my SSU patch (http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-August/025347.html ) I hope that everything is fine now. -Jakub -------------- next part -------------- A non-text attachment was scrubbed...

Hey Jakub, Thanks for working on this again, one more round :) Please merge the three testcases into one

Hello, Sorry for my stupid mistakes. I hope that everything is fine now. This patch fixes PR2218. There are no loads in example, however "instcombine" changes memcpy() into store/load.

Help pages for stop/warning reference the option "warning.length", e.g. from ?stop: Errors will be truncated to getOption("warning.length") characters, default > 1000. Essentially the same is in ?warning. Neither of these mention the hard-coded limits on the acceptable values of this option in options.c

Hello All, I want to ask about CentOS and money. Please do not start some kind of shitstorm over this, it isn't productive. I have just been looking at archive.org to see when the paypal option went missing from the donate menu at centos.org. I can't pin it down, but it was there on October 16, 2010 and isn't now, so that's the information I have on that point. There was a

Hello, I have an ESRI ArGis geo database directory which I would like to convert to geojson or a shape file (or anything else that I can read into R). Unfortunately that does not work out of the box with rgdal, because it does not come with the fileGDB or openfileGDB driver. I could successfully install gdal and the fileGDB...

Hi Tim, I may be missing something but using CCPassByVal is moving the pointer onto the stack - not what I'm after. I need to add an operation to the function prolog that actually makes a copy of the pointed to data. It is the responsibility of the callee to make the copy, not the caller - hence my trouble. (currently the callee can corrupt the original data viz pass-by-reference!) This

Rather then implementing kafs in MIT Kerberos, I would like to suggest an alternative which has advantages to all parties. The OpenSSH sshd needs to do two things: (1) sets a PAG in the kernel, (2) obtains an AFS token storing it in the kernel. It can use the Kerberos credentials either obtained via GSSAPI delegation, PAM or other kerberos login code in the sshd. The above two

Hi Tim, Thank you for the input. I think I follow you. I believe the LowerCall is doing what it needs to do - passing pointer either on the stack or in register as per ABI. The LowerFormalArguments() is where I am stuck. LowerFormalArguments () calls CCInfo.AnalyzeFormalArguments(Ins, CC_XCore), which calls the CC_XCore(). This is where I placed the CCIfByVal<CCPassByVal<0,4>> which

R gurus, Every so often(*) someone asks how to suppress scientific notation in printing, so I thought I'd give it a shot, but I need some help. The formatting decision is made(**) on line 286 of src/main/format.c : if (mF <= *m) { /* IFF it needs less space : "F" (Fixpoint) format */ where mF is the number of characters for "normal" printing and *m is the number

The main limitation of the shapefiles package that I put together is that it does not create shapefiles from R objects - rather it only writes shapefiles that have been read into R and manipulated within the constraints of the existing file structure. By this I mean that for example you can change the coordinates of points and write them back out. Or you can add a bunch of blank columns in the
