...to compile mcf program can reproduce such issue all the time. Probably it is my version's problem. Because I checked out 3.3version from SVN before published. Could you tell me where Manman modified ? I cannot port to new version very quickly after changing it a lot already.

Actually, it seems our own Eli has written rather a good description of these code models: http://eli.thegreenplace.net/2012/01/03/understanding-the-x64-code-models/. Well worth the read (the default models he talks about at the

Yep. I tried it. It used a movabsq instruction instead and a static allocation. Thanks a lot. I will read it immediately.

...on in lattice package, I want to label the y-axis with customized numbers. Like this: parallel(~iris[1:4] | Species, iris,horiz=FALSE,common.scale=TRUE, scales=list(y=list(at=c(0,2,3)))) But only "Min" label in the y-axis, nothing happened. Could anyone help me? Thanks. Regards, Pengcheng Yang

Hi, What version of clang are you using? I think r174785 is the fix. Manman On Tue, Nov 5, 2013 at 11:04 AM, lipengcheng <pli at cs.rochester.edu> wrote: > What do you mean by test case please ?

...blame ext3 for it? or should I just turn off the disk write cache? it seems Windows NTFS has less such problem than ext3, and no matter it's the problem of ext3 or mis-configured hardware, this behavior is really causes lots of people to doubt the stability of Linux file system. thanks, -- Pengcheng

This is from work that Manman did. I thought she'd fixed this particular issue though. Can you file a bug with a test case please?

...c" doesn't work ? One more thing, When I compile with O0, O1, the generated code is absolute addressing. like, callq *addr. but when compiling with O2, O3, the generated code is relative addressing, callq *addr(%rip). How could I make it always absolute addressing ? Thanks, - Pengcheng

Another finding is when I use both -code-model=large and -relocation-model=pic (!!!!!note changed), it still generate the static relocation. So does it mean -relocation-model=pic does not like to work with -code-model=large ? Thanks, -Pengcheng On Nov 6, 2013, at 1:52 PM, lipengcheng <pli at cs.rochester.edu> wrote: > Yep. I tried it.

...ted into assembly codes, it will be a jump instruction with a relative address, like jmp 01. My question is can I do some modification to let the jump instruction be with the absolute address ? Are there any compiler options to control this ? Really appreciate that if you can help! Thanks, Pengcheng

...xample, when I traverse all BBs during the instrumentation phase, there are 30000. But after code generation, there are 30100 BBs. For small scale of programs, there is no such issue. Can you tell me which of the succeeding phases changes the BB number ? How can I deal with this ? Thanks, Best, Pengcheng

Hi, All, Are there any supports about array region analysis both for serial program and multi-thread programs in LLVM ? I couldn't find them. Thanks, Pengcheng

Hi all, I want to setup a RAID storage system, where i have two systems connected to it. the filesystems are mapped out to both connectors. I want the master host mount them read write, and the slave read only. in my fstab on the slave I have a line like the following: /dev/sdb1 /mount ext3 acl,noauto,user_xattr,nosuid,ro 0 0 so in man 5 fstab, it is written, that when the 6. field
