Thank you! But I have one more issue on the clang normal build (without LTO) now. I find the small code model + "-fpie" build option will let clang generate some R_X86_64_GOTPCREL

Does R have a comparison operator similar to the Like function, for example: a<-"Is a Fish" b<-"Fish" if(b in a){c<-TRUE} Michael R Howard Micron Technology Inc. Boise ID. Fab C Engineering Software (FCES) Software Engineer

Hi, Multifractal Model of Asset Return (MMAR) is a relatively new model for financial time series this work was done by Benoit Mandelbrot, Adlai Fisher and Laurent Calvet. For those interested in the model you can find papers @ http://www.stern.nyu.edu/~afisher/papers.html (papers number 1164:1166) I'm new to R and I was wondering if anyone of you had tried to implement this model in R before I made any attempt by myself? In the event that no one as done it then I'd like to know if someone would like to work at it? My goal is to implement the mo...

OK, I get it. Adding "-pie" link option can force 64bits relocation address (e.g. EM_X86_64), instead of the 32bits one (e.g. R_X86_64_32S). I only used -fpic and -fpie in clang LTO compile option, and forgot add the "-pie" link option in ld. So my clang + ld LTO executable was still not position independent. Thank you all!

Andrew, That is not a clang issue. I think, in practice, {rcx, rdx, r8, r9} might not need to be spilled to "home area" in that case, because va_arg would not touch former 4 args. Lemme know if you had issues. I know it must be suboptimal, "home area" would be vacant in any cases afaik. It would be better to 4 args were spilled into the home area. To work on this, it might
