similar to: [LLVMdev] How to determine if a variable has been discarded

Thanks John, this is an easy way to achieve this goal, but I'm wondering if this is the only way? I have around 100 passes.

Eli, Thanks very much for your reply. That's what I want to know. It works for this example. But I usually have to deal with the optimized bytecode with "-O". See the example: ************** C source ************** int h (int j, int i) { int tmp; tmp = j+i+2; return tmp; } +++++++++++++++++++++++++++++++++++++ .ll file: ; ModuleID = 'simplecase.c' target

Hi, I want to get the mapping between C source's variables and bytecode variables. It seems that llvm doesn't provide this mapping, so I think a walk-around method is to get the instruction's mapping. I have to use llvm-gcc, not clang. Any advice? Thanks.

Hi all, Llvm can automatically group a list passes. I want to do some experiment to see the difference between grouping and non-grouping execution. Considering the following example, if I want to apply transformation A, B and C. The execution order is: A.doInitialization(); B.doInitialization(); C.doInitialization(); A.runOnFunction(); B.runOnFunction(); C.runOnFunction();

Hi, I want to know the variable mapping between the source and llvm bytecode. It seems that current llvm debugging information cannot provide this mapping directly. Here is my examples (llvm 2.7). In this exmaple, I want to know the mapping: tmp<--->%4. But current llvm's debugging information can only provide that the instruction "%4 = add nsw i32 %3, 2" is at line 3 in

Hi folks, I wonder how to get the statistic of which pass has been "really" applied and which one is not. For instance, I try to apply 20 llvm passes on a single C source code. But since the precondition of each pass may not be satisfied (try loop-unrolling to a source code without loop), some of these pass may not affect the final result. How to know which pass affect and

To Whomever is Interested, I have spent several days searching the web, help files, the R wiki and the archives of this mailing list for a solution to this problem, but nonetheless I apologize in advance if I have missed something obvious. The problem is this; I have a 5-column data frame with about 4.2 million rows, and want to create a new (and hopefully much smaller) data frame that

Do i always need to tell the decoder that some packets has been lost? I noticed that if i discard packets without passing NULL and advising the decoder, sometimes my system hangs and i need to reset my PDA. Since the decoder is mantaining a state, i suppose i always need to tell it a packet has been discarded through a sequence number check. Or can i just pass to speex_decode_int whatever i

Hi Duncan, But in the doc "Source Level Debugging with LLVM", it shows that llvm 2.6 could get column number. There's an example in the doc as following: http://llvm.org/docs/SourceLevelDebugging.html 1. void foo() { 2. int X = 21; 3. int Y = 22; 4. { 5. int Z = 23; 6. Z = X; 7. } 8. X = Y; 9. } Compiled to LLVM, this function would be represented

I am fairly confident that these issues are related to killing the scriptindex process ungracefully causing blocks that were queued for writing to disk to not get written. I mention to send you the file because it could be that you would see almost immediately with the situation is. Thanks > ----- Original Message ----- > From: oscaruser@programmer.net > To:

I've been using rsync for a long time, and it's very cool. For the first time, last night, I got a message I don't understand. I am using rsync 2.6.4 on Fedora (FC4) Linux to a Fedora (FC3) Linux machine. The command I am using is: rsync -av --delete-excluded --exclude="*~" --exclude="#*#" <source dir> remove_machine:<dest dir> I got the following

You need to let the know packets are missing so it can generate something meaningful instead. Otherwise, you'll also have less packets to play, which means "something" has to be inserted (zeros, clicks, the content of the kernel memory, ...) instead. As for crashing, it shouldn't happen and I wouldn't be surprised if it had more to do with a soundcard underrun occuring from

I have C++ project that builds fine with g++. But when I try to replace g++ with clang++ I get such errors (see below) during link. What might be a problem? Yuri --- errors are like this --- local symbol 1: discarded in section `.text.SomeSymbolHere1' local symbol 2: discarded in section `.text.SomeSymbolHere2' ... ...

Does the keyword/action discard work by default or is there something I have to do in the configuration to get to work... maybe I missed something on http://wiki.dovecot.org/LDA/Sieve I have the following rule: if anyof ( header :contains ["Subject"] ["Test Discard"] ) { discard; stop; } but it delivers to INBOX with or w/o the "stop;". If I change

Hi, I tried llvm-gcc -g -O0 on several cases, but the column field of meta data always shows zero in created ll code. Does llvm-gcc emit column # info ? Or I should add some option?
