If you use llvm-gcc3, you can make an unoptimized like this: llvm-gcc -S hello.c -o hello.s Seung J.

Using llvm-gcc -emit-llvm -O0 -S blah.c will give you blah.s that is unoptimized. I guess passing that to llvm-as would get you an unoptimized .bc. llvm-as -debug-pass=Arguments blah.ll says it is only doing Pass Arguments: -domtree -etforest -verify scott On 5/29/07, omiga <omiga at ustc.edu> wrote: > > Hi everyone, > > Llvm-gcc compiles the programs into bytecodes with

Hi everyone, Llvm-gcc compiles the programs into bytecodes with some optimizations. How can I get unoptimized bytecodes? Thanks.

Hello. My name is Seung Jae Lee. I'd like to ask you onething about converting to ARM assembly code. I saved the simplest C code shown in your LLVM webpage as 'hello.c' And I made 'hello.bc' by "$ llvm-gcc hello.c -o hello". In order to make ARM assembly code, I typed "llc -march=arm hello.bc -o hello.arm" But, I met this error. llc: ARMISelDAGToDAG.cpp:73:

Ok, here are a few suggestions and comments: 1) LLVM has the capabilities to do everything that you are trying to re-implement. 2) Have you looked at the C backend? It recreates loops. It may not create "for" loops but you can hack on it to do that. 3) The way you are converting out of SSA is wrong. You will suffer from lost copies. You should look at using demotePHI(). see

Hello. I am Seung Jae Lee making a LLVM backend for a new architecture XCC. I found that the instructions use variable names which actually used in the source coding for operands unlike most architectures which use usually register names or addresses as operands. LLVM backend examples such as ARM, SPARC seem to use register names or addresses for operands. How can I implement this on my backend?

Dear Prof.Adve and Bill, I deeply appreciate your comments and concerns. (Please forgive my late response. I've tried some more cases to make this issue) As Prof.Adve mentioned, I need to explain exactly what my problem is, but I have no good ability that I can explain it in this plain text space. For this reason, I made a .pdf file and linked it as follows:

Hello. Nice to meet you. My name is Seung Jae Lee, a graduate student in UIUC CEE, who is working in NCSA for the present. Nowadays I am trying to develop LLVM backend to spit out CHiMPS assembly code. In the process, I installed LLVM codes on my home directory in the host computer. But I don't think it was installed properly. While bootstrapping the LLVM C/C++ Front-End, I met several

Hi all, When connect to a remote rsync server, ofter it will give some site- specified messages, say, the following one: ------------ _______________________________________________________________ | University of Science and Technology of China | | Open Source Mirror (mirrors.ustc.edu.cn) | |===============================================================| |

Basically, I''m trying to crop multiple images out of a remote/original scene.. Think flickr ''tagging'', only, the pixs in the tagged boxes become their own unique images.. by way of simulating an upload from the controller using attachment fu.. can''t quite figure out the specific method in fu that would allow me to do this.. I''m so near the edge right

Hi all, I'm using Debian, I want to make a local repository which can let me install packages more conveniently. Considering that the rsync tool is the Debian official proposed tool for syncing the files among its different rsync server sites, I use the rsync client to downloading the deb packages from the different rsync servers distributed around the world-wide for good loadbalancing and

I use VS2005/Vista, which works well...

I can see there is a MIPS implementation in LLVM repository but it looks like uncomplete (that is, I'm not even sure it can compile any source). What I hope is to have a complete MIPS implementation so I can adapt

Hello, guys. I just tested -reg2mem pass to see how it changes my bitcode. E.g., for the following simple C code: ------------------------------------------------------------- int foo() { int i,j; int sum = 0; for (i=0; i<10; i++) { sum += i; for (j=0; j<3; j++) sum += 2; } return sum; } ------------------------------------------------------------- I could get the

Bill, Depending on what Seung's problem is, converting *out* of SSA form may actually be the wrong thing to do.
