similar to: [LLVMdev] Why declaration of llvm.eh.selector differs between documentation and in .ll code written by clang++?

I accidentally ran into a JIT scenario where a call instruction, executing an external non-generated C function, executed between a llvm.eh.exception and a llvm.eh.selector instruction would clobber the register (register index __builtin_eh_return_data_regno(1)), used by the return value of llvm.eh.selector. The behavior of the call depends on the function called even though none of the

Hello, I have been doing some looking at openssl 0.9.7 and openssh3.5p1 and found a minor descrepancy. RAND_bytes() is called around line 69 of openbsd-compat/bsd-arc4random.c. It checks to see if the return is not zero. The RAND_bytes function can also return -1, too. All the code in openssl uses <=0 for the test rather than !. Best Regards, Steve Grubb

Probably, it's an obvious info, but I have not found anything in R FAQ concerning this feature/bug. The results of ks.test and wilcoxon.test (in the Mann-Whitney version, paired = 'FALSE') don't coincide with the results from the other statistical packages, e.g. Statistica, Medcalc, and (as for MW test) from the numerous online MW tests. E.g. Statistica p-value=0.0435353 Medcalc

Funny I remember that code (DwarfEHPrepare), wondering at the time why it was doing this. Thanks for your response, as I can now stop trying figure out how I am introducing this error, and more importantly now will be able to go back to DwarfEHPrepare, and understand it better knowing one of its purposes. However the result of my tests indicates that the underlying register used by the

Per subject; I went to look for a description at http://llvm.org/docs/ExceptionHandling.html , but it wasn't there. Also, apparently, __builtin_unwind_init is supposed to force callee-saved registers to be spilled, but llvm.eh.unwind.init doesn't do that. This matters because Boehm GC expects the intrinsic to do that. -Eli

Hi Garrison, > I hacked together a version of DwarfEHPrepare.cpp which tries to deal with the ordering of llvm.eh.exception and llvm.eh.selector. > The hacked is contained within the attached patch. it looks like you tried to copy the code for eh.exception. There are two problems with this: (1) the eh.exception code really needs to be rewritten to make use of the new SSAUpdator (then all

Hi Duncan, I hacked together a version of DwarfEHPrepare.cpp which tries to deal with the ordering of llvm.eh.exception and llvm.eh.selector. The hacked is contained within the attached patch. Motivation: I recently created a decent amount of hand coded IR (via the llvm C++ API). In order to help me runtime debug the code, I created automatic constructors which would trace entries into the

Aha! Although I'm not an everyday samba programmer, I have found a descrepancy between a windows code snippet running on a windows server, and on a samba (2.2.7a, but also earlier) systems. This causes the dreaded Desktop.ini problem (yay!) and probably some others too! The test code in windows: #include "stdafx.h" #include <windows.h> int main(int argc, char* argv[]) {

Hi, I do want to use the Mann-Whitney test which ranks my data and then uses those ranks rather than the actual data. Here is the R code i am using: group1<- c(1.34,1.47,1.48,1.49,1.62,1.67,1.7,1.7,1.7,1.73,1.81,1.84,1.9,1.96,2, 2,2.19,2.29,2.29,2.41,2.41,2.46,2.5,2.6,2.8,2.8,3.07,3.3) > group2<-

I all I am trying to create a matrix for a network diagram: # 1. The following produces two dataframes. The table "place" is a dataframe of all places made from "tra" a tracing table that has the source place and destination place. The table "details" is a dataframe of all source and destination properties. src=rep(c(1:3),each=5) des=c(16:30) rsk=rep(3,5)

I'm new to linux so be patient. I'm running Ubuntu Hardy and have Wine 1.1.5 installed. After installing Family Tree Maker 2009 successfully, it will not execute. The screen comes up like it is going to start and says the database needs to be compacted and then the screen fades away. I decided to run FTM 2009 from the terminal and see what is happening. Obviously a lot of things.

Hi All, Is there a way to tune the zfs prefetch on a per pool basis? I have a customer that is seeing slow performance on a pool the contains multiple tablespaces from an Oracle database, looking at the LUNs associated to that pool they are constantly at 80% - 100% busy. Looking at the output from arcstat for the miss % on data, prefetch and metadata we are getting around 5 - 10 % on data,

Hi, According to comments in file fs/ocfs2/cluster/quorum.c:70 about the self-fencing operations : /* It should instead flip the file ?* system RO and call some userspace script. */ So, I tried to add it (but i did'nt find a way to flip the fs in RO). Here is a proposal for this functionnality, based on ocfs2-1.4.7. This patch add an entry 'fence_cmd' in /sys to specify an

Hi, Could someone please tell me how to perform a Mann-Whitney U test on a dataset with 2 groups where one group has more data values than another? I have split up my 2 groups into 2 columns in my .txt file i'm using with R. Here is the code i have so far... group1 <- c(LeafArea2) group2 <- c(LeafArea1) wilcox.test(group1, group2) This code works for datasets with the same number
