similar to: Llvm pass to remove temporaries

Hi, I’d like to run clang with some optimization passes (-reassociate, -simplifycfg, -dce ) But in the end I need to dump the llvm IR (no link to assembly generation). I didn’t find any way to do that. I found out that passes are run via opt, but opt generates bc code, and I want IR. Any help will be welcome Thanks, Régis -------------- next part

hello guys: I am in trouble with get the identifies of the unnamed temporaries from the instruction of LLVM IR. for example: instruction: %4 = mul nsw i32 %1, %width unnamed temporaries: %4, %1 how to get them? I have tried several iterators(op_iterator,value_op_iterator) and getOperand(int) function,but none of them works. does anyone know how to get it? thanks very much -- View this message

I'm trying to vectorize a simple C code. My problem is that I don't quite understand the relationship between clang --target option and the cores mentioned in X86.td as well as other X86 related options (such as -mtune). Below are the command and the code that I'm trying to vectorize. The code compiles but I don't see any vectors. What am I doing wrong? Any help is appreciated.

I wonder what is the right approach to obtain the address and size of LLVM (compiler) generated temporaries? E.g. %0 = %x + %y store i32 i0, i32 %z, align 4 How can I get the address of %0 (which could be either a stack or heap variable)? Thank you Chuck

hi, Duncan: thanks for your patience. i have tried it. using instuction: errs()<<i->getOperand(0); but it prints the address: someting like 0x1139700; i checked the defination of getOperand() is Value* getOperand( unsigned int i); so is there someting i missed? -- View this message in context:

Most names in the IR are just there to make it easier to read and can safely be removed. You can't rely on instructions having names, and as you saw often they do not have a name. Even if they start off with a

Could people who are experiencing boot-time hangs in 4.9-PRERELEASE try the following patch to see if it helps? I've had one positive report so far, but it would be helpful to get more feedback to determine if this is the right fix to be committed. The problem was that interrupts were getting unmasked too early in the boot process, causing an interrupt storm that usually occurred while USB

hi, Duncan Sands: thanks for your reply old friend. the reason why I want to get the unnamed value is that I am doing some analysis based on the IR code. And IR is in the form of SSA(static single assignment). so i need to get the operands of each instructions including a lot of instructions like this (%4 = mul nsw i32 %1, %width). the unnamed values are the connection of instructions, if i

hi, Duncan, thank you for your reply; instruction "i->getOperand(0)->dump()" may print the %4 in the screen, but how can i store it in a variable like char * oprand="%4" ? -- View this message in context: http://llvm.1065342.n5.nabble.com/get-the-identifies-of-the-unnamed-temporaries-from-the-instruction-of-LLVM-IR-tp56572p56588.html Sent from the LLVM - Dev mailing

hi Sean Silva: i really appriciate for your reply. but you konw that "dump()" instruction can print "%4" in the screen and each time print the same name "%4" not "%5" or "%6" for the same unnamed value. so there must be a way to determinate it. if "dump()" instruction can print it on the screen, can i find some way to store it in a char *

hi all, I have a strange problem using the libsmbclient api.. retrieving or stating files named with percents in is for some of them impossible. Example: a file located at "smb://test/test/%7C2.txt" cannot be retrieved with my code, smbc_open fails with the code NT_STATUS_OBJECT_NAME_INVALID. I am not sure but, url encoding/decoding that would escape strings with "percent"

All: My company has an existing ESI IVX E-class system with 45 phones. I can add one more card, to expand it another 6 phones, but it's $8000, and then the system will have to be replaced. I have the Asterisk server up and running, with 2 sip lines from the local phone service. (Thanks to you guys, it is working great!). I'm pretty sure this is the way the company will move, and

Hi, I was trying to use CloneBasicBlock() (in Cloning.h) to clone basic blocks in one of my transform passes. For example, when I have a basic block like: bb1: ; preds = %bb load i32* %i, align 4 ; <i32>:11 [#uses=2] load i32* %n_addr, align 4 ; <i32>:12 [#uses=2] icmp slt i32 %11, %12 ; <i1>:13 [#uses=2] cloning it gives something like: bb1_clone: ; preds = %entry

Hello, I am developing an agent-based model to simulate the spread of infectious diseases in heterogeneous landscapes composed of habitat polygons (or clumps of connected cells). To simplify the model, I consider a habitat grid (or raster) containing the polygon ID of each cell. In addition, I have epidemiological parameters associated with each polygon ID. At each time step, the parameter values

As soon as s->tmp would "escape" f() the compiler will have to write it. I think you may

Hello, Before I get into troubles I ask here: I make a call to a C function using .C. What I would like to know is if the arguments in the .C call can also be 'temporary' objects. An example will illustrate this: # here we don't have a temporary Obj1 = 5 .C("Func", as.integer(Obj1 ), ...) # certainly works # here we do have a temporary Obj2 = 5 .C("Func",
