Hi Dear All, This is a function which contains Covariance Ratio and Likelihood Distance values (CVRi, LDi). i want to compute the all row's values, that is run this function for nrow(X) times. The X and Y matrices are; X<-matrix(c(1125,920,835,1000,1150,990,840,650,640,583,570,570,510,555,460,275,510,165,244,79,232,268,271,237,192,202,184,200,180,165,151,171,243,147,286,198,196,210,327,334,7160...

Hi, Compiling for both x86 and ARM with llc aborts after this pass. I have a simple helloworld.c program. I am attaching the .ll file created by: *clang -O3 -g -emit-llvm hello.c -c -o hello.bc* *llvm-dis hello.bc* Thanks again for the response!

I noticed the following this week. No idea how long its been happening because I have not tested deleting folders hardly at all. Steps to reproduce: 1. Create a folder "NewFolder", click on it in thunderbird so an index dir is created: ls -ldi Maildir/.NewFolder/ 1504062 drwx------ 5 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/.NewFolder/ ls -ldi Maildir/dovecot/boomhauer/private/indexes/.NewFolder/ 4198832 drwx------ 2 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/dovecot/boomhauer/private/indexes/.NewFolder/ ls -li Maildir/doveco...

...There are different instructions which require different fixups to be applied depending on whether pointers are located in data space or program space. Take the ICALL instruction - it performs an indirect call to the pointer stored in the Z register. We must first load the pointer into Z via the ‘ldi’ instruction. If the pointer is actually a pointer to a symbol, we need to emit a AVR_LO8_LDI_GS relocation, otherwise we emit a AVR_LO8_LDI relocation. There are a few other cases, but they’re irrelevant for this discussion. We can quite easily look at the GlobalValue* that corresponds to the poi...

Sean, Thank your valuable opinion. I am doing the revision history now. I also review my book and find I made a mistake in LDI instruction. According cpu0, this instruction is move immediate value (for example, 5) to register, not add immediate value to register. I need to fix this for reader's feeling. I am an experienced programmer and I am less-experienced book writer. Please correct me if you find anything wrong....
