similar to: [LLVMdev] a strange emit of llvm-g++

Hello, guys. I just wonder if there is any way to spit out LLVM assembly without any basic block division. E.g., If I emit LLVM assembly for the following simple code: ------------------------------------------------------------ void f_loop(long* c, long sz) { long i; for (i = 0; i < sz; i++) { long offset = i * sz; long* out = c + offset; out[i] = 0; } }

Thank you for reminding me the notion of the basic block. Of course, I know all the assembly takes the form of BBs and is divided into units of BB. OK. It looks better for me to explain what I wanted to do more clear from the first. Actually, I am working on emitting out an assembly of VM by using LLVM. LLVM assembly looks similar with this VM assembly except BB. The VM assembly does not have the

Hello, guys. I am trying to construct higher-level 'for' from the low-level LLVM bitcode(ver 1.9). It's partly successful thanks to David A. Greene's advice suggested to use Control Dependence Graph(CDG). I could find which BB contributes to form which loop with CDG. For example, for this simple function: ----------------------------------------------------------- void bsloop(int

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

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:

Xi, I just installed VS2005 pro w/ SP1 for Win Vista.

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:

On the document about writing an LLVM backend, I became to wonder what the 'virtual register' is in the following statement. "You also need to define register classes to contain these registers, such as the integer register class and floating-point register class, so that you can allocate virtual registers to instructions from these sets, and let the target-independent register

Hello. I updated my LLVM with version 2.1 from 1.9. But I am curious why I still have signed integer type. I still get LLVM IR as follows: ...... ...... bb8.outer: ; preds = %bb10, %entry %i.0.0.ph = phi uint [ 0, %entry ], [ %indvar.next26, %bb10 ] ; <uint> [#uses=2] %sum.0.pn.ph = phi uint [ 0, %entry ], [ %sum.1, %bb10 ] ; <uint> [#uses=1] br label %bb8 bb3: ; preds = %bb8

Hello, LLVM guys. I've tried to emit the following simple function to LLVM assmbly. --------------------------------------------------------- void test(long s, double* a) { char h = ttt(s); *a = s; mmm(); } --------------------------------------------------------- It's spat out as follows: --------------------------------------------------------- void %test(int %s, double* %a) {

Can you recommend any good book or reference for backend implementation? I skimmed some compiler books but it seemed to be more about front-end, parsing, optimization etc. Would you mind suggesting some books containing more about backend? Thank you.

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

Hi, guys. Is there any easy way to know the leaf BB node in the CFG which is not terminated by such a 'br' instruction? E.g., for the following LLVM assembly: ----------------------------------------------------------- int %foo2(int %k) { entry: br label %bb bb: ; preds = %bb, %entry %indvar = phi uint [ 0, %entry ], [ %indvar.next, %bb ] ;

This is from 'early JIT tests' thread on comp.lang.misc. Given :- int ltst(int x) { int i, j; j=0; for(i=0; i<x; i++)j++; return(j); } This is from the online LLVM compiler. AND It does not seem to optimize it down ! ; ModuleID = '/tmp/webcompile/_24843_0.bc' target datalayout = "e-p:32:32" target endian = little target pointersize = 32 target triple =

Thank you, Bill. Seems to be better. Anyway...Is there a way I can do what you showed for me? Thanks, Seung J.

Thanks for your comment. I also tried for LLVM 2.2 but got the same compilation errors on VS2005. (I didn't modify anything before the compilation) I just wonder if I need bison and flex even just in the case of compiling them on VS2005 without changing anything because the LLVM doc says "If you plan to modify any .y or .l files, you will need to have bison and/or flex installed where

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

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
