Hi All, I would like to know if there is an API/method that I can use to get the name of the file being processed in a dynamically loaded function pass. In other words, if I invoke a pass as follows opt -load pass.so -hello src.bc -o src.hello.bc where pass.so is a functionpass, I would like to get the filename "src.bc", in the doInitialization/doFinalization method. My intent is to

Hi All, I am using llvm-3.0 release version for compiling some files. I have a cpp file on which I did a few custom passes. After that I used llc to convert the *.bc file to *.s file at -O1 optimization level. llc took ~2630 seconds to perform this conversion. I timed llc and these are the top three passes that is taking most of the time. ---User Time--- --System Time-- --User+System--

Hi All, I am creating an instrumentation pass using LLVM libraries. I am using clang++ (version 2.9) to compile cpp code into LLVM bit code. When I generate the llvm bit code using clang++ using -O3, I get many instances of instructions that look like the following. br i1 icmp ne (i8* bitcast (i32 (i32)* @pthread_cancel to i8*), i8* null), label %bb23, label %bb25 Here three LLVM instructions

Hi All, I have a question on ConstantExpressions and llvm intrinsic memcpy/memset/memmove. I am using llvm-2.8 release. In one of the C programs that I am compiling using clang frontend, the call to memcpy instrinsic looks like the following call void @llvm.memcpy.p0i8.p0i8.i64(i8* %tmp2, i8* bitcast (%struct.ta* @tret to i8*), i64 4, i32 4, i1 false), !dbg !19 The second argument to memcpy is

Nick, Unfortunately this doesn't answer my question I don't think. It seems that -instnamer, as you mention, names the instructions but still does not name the local variables. So there really is no way to do this shy of creating (or basically copying) the API from AsmWriter (seems very dedundant to me)? This seems like a large failing?

Nick, Is there a clean way to tell the difference between dst and src operands in operations without assignment "=" (ie, store)?

Hi, I've been upgrading some custom LLVM passes to work with LLVM 2.6 instead of LLVM 2.5. I've noticed that in 2.6, some functions seem to have several local values with no name (where getName() returns an empty string). I never saw this in 2.5. Is this a known change in behaviour? Is there some handy way to get unique, deterministic names assigned to all values in a function? Thanks,

When AsmWriter prints "%y = add i32 %x, 1", the name of that add instruction is "y" and

Hi Bill, With the latest llvm version I'm getting the following error: opt -instnamer < core-device.c.bc > core-device.o.bc Attribute 'nobuiltin' only applies to functions! void (%struct.fw_csr_iterator*, i32*)* @fw_csr_iterator_init Broken module found, compilation aborted! 0 opt 0x0000000001914bf1 llvm::sys::PrintStackTrace(_IO_FILE*) + 38 1 opt

Hello, I'm having a little problem with passes that use LoopInfo. Their statistics aren't the same when I execute the same pass multiple times in the same program. After some investigation, I've found out that LoopInfo is the root of the problem. I wrote a little pass that counts the loop headers (number of basic blocks for which LoopInfo.isLoopHeader(BB) is true). I've picked

Can anyone tell how to get the result name or instruction name of all instruction? For example if the instruction is "x=add y,z", here i need "x". Using getName(), i am getting some instructions result name, but llvm produces some instruction like "%0=add i32 tmp, 1", here getName() shows empty string as result name. So please help.

It looks like the AsmWriter is generating the local variables (SlotNum)s on the fly in that file (AsmWriter.cpp), so is there any way at all to get this information from the operation itself, via Instruction, Value or Type? -------------- next part -------------- An HTML attachment was scrubbed...
