similar to: [LLVMdev] GCC3.5 tree-ssa

why doesn't llvm transfer bytecode to RTL form? I mean the cross-platform compile in GCC. Could LLVM do that? maybe tree-ssa also create the representation with a testual format if needed. is it very difficalt? I want to know.

Does LLVM called the pthread directly? and what time do you plan to release Java front end? I'll try this. ----- Original Message ----- From: "Chris Lattner" <sabre at nondot.org> To: "yue" <qiangyue at ict.ac.cn> Cc: <llvmdev at cs.uiuc.edu> Sent: Wednesday, December 24, 2003 12:47 PM Subject: Re: [LLVMdev] GCC3.5 tree-ssa > On Wed, 24 Dec 2003,

The short version is that LLVM is more mature and stable than tree-ssa is, LLVM supports interprocedural and runtime optimization, and LLVM has a well defined intermediate representation with a textual format. On the other hand tree-ssa may be a part of GCC 3.5

we work on distribute software development, most programs are wroten in java. but the running speed of that is slowly, it requires thread library to support, you know.

I'm not sure exactly what you mean here. LLVM does not currently have a Java front-end, though there is one in development. Thread support should not be a problem, you can

Sure, it would be a realtively straight-forward (but large and hard to get right, if you're not a GCC expert), project to build an LLVM front-end for GCC. This would allow you to effectively use LLVM as a mid-level representation for

Try llvmgcc pthread.c -o pthread.ll -pthread You have to link in the pthreads library, and I believe -pthread is all you need on a redhat 9 box.

hi, I try to build hello.cpp using both llvmg++ and GNU g++, the generate llvm bytecode's size is about 960K, and the size of binary code generated by g++ is only 13K. Could anyone explain the difference between the two result?

If an operation can be written in C/C++ or some other high-level language, then it should be. It can be directly compiled to LLVM bytecode. In our case you can llvm-dis llvm-gcc/lib/libstdc++.so to see what we compile it into. > also in RISC system Data/Inst Cache

hi, In high level languge there are usually have time and sync instruction, to handle async and sync operation. I want to know how LLVM take an count of these. thanks yueqiang 2003/12/19 -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I am new to R and have a couple of questions. My data set contains the variables "Bwt" and "Hwt", which are bodyweight and heartweight, respectively, of a group of cats. With the following code, I am making two plots, both to be viewed in the same plot window in R: library(MASS) maleData <- subset(cats, Sex == "M") linreg0 <- lm(maleData$Hwt ~
