Volodya, I think you may need to update your CFE and rebuild. I compiled the test using my local build and I didn't get the results you see below. I'm also very surprised to see this output. The first %tmp.11 should have been %tmp.1 .. not sure how it got corrupted. In any event, the attachment is obviously generated by code that runs quite differently because the virtual register names

Hello, when I'm compiling test/Programs/SingleSource/UnitTests/2003-05-26-Shorts.c I get LLVM assembler which looks like: int %main(int %argc, sbyte** %argv) { entry: call void %__main( ) %tmp.11 = call ulong %getL( ) ; <ulong> [#uses=16] %tmp.3 = cast ulong %tmp.11 to long ; <long> [#uses= %tmp.5 = cast ulong %tmp.11 to

When I increased COLS to the point where the loop could no longer be unrolled, the selection dag code generator generated effectively the same code as the default X86 code generator. Lots of redundant imul/movl/addl sequences. It can't clean it up either. Only unrolling all nested loops permits it to be optimized away, regardless of code generator. Jeff Cohen wrote: > I noticed

Hi, Is there a way to modify the string such as char a or char b? Could I use the way like "Replace an instruction with another Value" in Programm Manual? In fact, what I am interested in is string with visible expression, not all string, and I am trying to hide the orignal string by using simple way like XOR.. Is there a way to reorder the basic blocks? Thanks. Qiuyu C Source

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? BWT: I rebuild the cfrontend in RH linux9.0, but when I build the hello.cpp the llvmG++ reports warnings too, it shows: ----------------------------- [yue at RH9

I noticed that fourinarow is one of the programs in which LLVM is much slower than GCC, so I decided to take a look and see why that is so. The program has many loops that look like this: #define ROWS 6 #define COLS 7 void init_board(char b[COLS][ROWS+1]) { int i,j; for (i=0;i<COLS;i++) for (j=0;j<ROWS;j++) b[i][j]='.';

I have an objective-c file, bar.m, that I try to process in the following way generating the error shown below. Any help would be appreciated. I suspect the error is in the first few lines of output. thanks, Todd > cfrontend-g++ -o bar.bc bar.m > llvm2cpp -o bar.cpp bar.bc > g++ -c bar.o bar.cpp > ld -o bar bar.o -l objc -l LLVMCore -l LLVMSupport -l LLVMSystem > ./bar Global

hi, I want to know what is exact meaning in the following code. target endian-- %struct..TorRec-- %struct.TorRec-- implementation-- ;<sbyte>[#uses=1/0]-- how to explain them in details? Does anyone give me a guide? thanks yueqiang -------------------------------------------------------------- target endian = little target pointersize = 32 %struct..TorRec = type { int, void ()* }

I am creating types through this interface and I get quite a mess seen below. And this is

After looking at this problem longer, I believe that there is something wrong with the disassembler. When I run my transformation and then disassemble the output, I get bytecode that looks like: ----- int %main(int %argc, sbyte** %argv) { entry: alloca int ; <int*>:0 [#uses=3] alloca sbyte** ; <sbyte***>:0 [#uses=3] store int %argc,

I am writing a transformation that needs to add a call to a function F() at the beginning of main() with the addresses of argc and argv as parameters to F(). However, the bytecode file I'm transforming has not allocated space on the stack for argc and argv. So, I developed my transformation to change main() from: ----- int main(int %argc, sbyte** %argv){ entry: ... // some use of

I am trying to understand the hello word assember example. This is my version: %str1 = internal constant [13 x sbyte] c"Hello World\0a\00" declare int %printf(sbyte*, ...) implementation ; Functions: int %main() { %str2 = getelementptr [13 x sbyte]* %str1, long 0, long 0 call int(sbyte*, ...) *%printf(sbyte* %str2) ret int 0 } Why is getelementptr being given two "long

Hi, I'm working on a CS326 compiler project, and I'm having some problems using string functions. Some LLVM programs produced are either aborting or giving incorrect results; however, if I disassemble the LLVM bytecode and recompile with GCC, everything works fine. I encountered the following error when running lli with '-force-interpreter' option: "Tried to execute an

Hello! I get some odd behaviour using my structs: "myKernelMap" = type {int (sbyte*)*, int ()*} "Kernel" = type {"myKernelMap"*} The second member ( int()* ) is a pointer to the %getchar() function. I want to call getchar using this function: int "callmyKernelgetchar_kernel"("Kernel"* "myKernel") { "PTRMAP" =

I'm trying to figure out the unwind primitive. I've written a program which should: 1. Recursively grow the stack until it reaches a threshold 2. Then unwind and print a message Instead what happens is: 1. Recursively grow the stack until it reaches a threshold 2. Then it dies with: Abort trap Can you point me to an example using uwind that "works" ? Thanks. Here's the

Hi When I compiled sendmail v8.11.6 with LLVM 1.2, I found some variables with strange type, such as: %sys_errlist = external constant [0 x sbyte*] ; <[0 x sbyte*]*> [#uses=3] %tmp.24 = getelementptr [0 x sbyte*]* %sys_errlist, long 0, long %tmp.23 ; <sbyte**> [#uses=1] The process of getting these is: 1. entry sendmail-8.11.6 directory 2. make
