similar to: [LLVMdev] signed integer types still in LLVM 2.1

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, 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

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:

Following the instructions here: http://llvm.cs.uiuc.edu/docs/TestingGuide.html#run I get an error running configure in the llvm-test directory. ./configure --with-llvmgccdir=/localhome/tbrethou/cfrontend/sparc/llvm-gcc/ --with-f2c=/home/vadve/shared/localtools/sparc --with-llvmsrc=/localhome/tbrethou/llvm --with-llvmobj=/localhome/tbrethou/llvm Error: [cut lots of config output] checking

Thank you for this comment, Mike. So... your suggestion is to make a valid transform for each loop like: >for (;C;) { > S >} > >is to transform: > >top: >if (!C) goto end; > S >goto top; >end: For now, my code is incomplete so not ready to present for audit yet but I hope it asap. In fact, I couldn't understand what you said: >The cost of the .pdf

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

It's no surprise 486 code would perform much worse than i686 code. These compilers need to target the same architecture. Ideally the Makefile would include

Dear Wojciech Matyjewicz: Thank you for your advice. I could follow what you had suggested upto opt -analyze -loops bsloop-opt.bc Therefore, I could get the prints you had showed me as follows: -------------------------------------------------------- Printing analysis 'Natural Loop Construction' for function 'bsloop': Loop Containing: %bb16, %bb13, %bb8, %bb1 Loop

Hi all, I am a newbie to LLVM and tried experimenting compile a small C program with it. This is what I did: 1. Wrote a simple C program with some dead code. 2. compiled it with llvm-gcc. [$ llvm-gcc -emit-llvm -S deadc.c] 3. Fetched it to assembler. [$ llvm-as deadc.s] 4. [$ opt -analyze -ade deadc.s.bc] [Ran without -analyze switch also: $opt -o final_opt -verify-each -globaldce -f deadc.s]

MetaSplit is an anlysis I just finished writing. It doesn't alter anything, all it does is build a set of "program instructions". For some reason even though if I run it with any other combination of passes I've found, anytime I run it with mem2reg I get a seg fault in dyn_cast! Here's output: Starting program: /mounts/zion/disks/0/localhome/pmeredit/llvm/tools/Debug/opt

Hi everyone, I have replayed the "unix benchmark v3.6 dhrystone 2" test. You can find the archive of the test here : http://www.phoronix-test-suite.com/benchmark-files/byte-benchmark-1.tar.gz To play the test on gcc : make ./Run dhry2 To play the test on llvm-gcc : Replace in Makefile : CC=gcc by CC=llvm-gcc in Run : CC=gcc by CC=llvm-gcc make ./Run dhry2 Some information on the test

Hi All, I need to write as text files 1000 ish variation of the same data frame, once I permute a row. I would like to use the function write.table() to write the files, and use a loop to do it: for (i in 1:1000){ bb8[2,] = sample(bb8[2,]) write.table(bb8, quote = F, sep = '\t', row.names = F, col.names = F, file = 'whatever?????.txt') } so all the files are called

Hi, Found CloneBasicBlock utility only does the cloning without any remapping. Consider below example: Input block: sw.epilog: ; preds = %sw.bb20, %sw.bb15, %sw.bb10, %sw.bb6, %sw.bb2, %sw.bb, %while.body, %if.end29 %no_final.1 = phi i32 [ %no_final.055, %while.body ], [ 1, %if.end29 ], [ %no_final.055, %sw.bb20 ], [ %no_final.055, %sw.bb15 ], [
