Hi, we want to use LLVM together with clang internally for preprocessing and Co. Therefor we would like to integrate it in our buildsystem. The nicest thing for us would be a local git repository mirror, to allow us to easily create own branches and Co. Is there some official git repository to clone from? I looked up the archives and seen that creating own clones of the SVN via git svn is not

I think the clang frontend could use that to allow better static analysis of integer overflows on

Hi, it seems that e.g. on Windows, where the filename encoding is not UTF-8, it is impossible to use any filenames containing e.g. german umlauts or chinese characters, because the in LLVM used encoding collides with the encoding used by the OS. There is a open bug for this http://llvm.org/bugs/show_bug.cgi?id=10348 It seems there were patches submitted to fix it, but they were never applied as

It's not *very* easy to do, but if you were to pull in the new branch, and then rebase the old branches onto the proper revisions of the new one, you *could* keep your branches. Also, any idea what is *very* soon? Are we talking this month, or maybe this year?

Hello, >From [1], trunc does not seems to have a nsw/nuw attribute. Is it possible to have that? Or do we have that and it is not up-to-date? The definition would be: If the nuw keyword is present, the result value of the trunc is a poison value if the truncated high order bits are non-zero. If the nsw keyword is present, the result value of the trunc is a poison value if the truncated high

Dear testers, 5.0.0-rc3 was just tagged. This is a release candidate in the real sense: if nothing bad comes up in testing, this is what the release is going to look like. Please build, test and upload binaries to the sftp (use the /data/testers-uploads/ directory) and let me know what issues remain. I know we're a little bit behind schedule, but hopefully we can get to 'final'

Dear all, I've got a list L <- list(L1 = list (foo = "bar" , SL = NULL ) , L2 = list ( foo = "bar" , SL = list (SSL1 = list (DF = data.frame(val = 21, foo = "bar") , DFOO = list(foo = "foo", bar = "bar") ) ,

Hi all, When writing my custom passes, I often emit log messages to llvm::errs() like so: llvm::errs() << "Could not handle instruction: " << *Inst << std::endl; where Inst is a pointer to an Instruction. I've profiled my code and found that this way of printing an Instruction takes a very long time: indeed, it is the bottleneck of my pass. Of course, I could

Hello, at our company we are using Samba 4.3.2 in conjunction with Windows 7. We use the Windows 7 machines for our nightly compiles. However, occasionally the schedules compiles stop with a Windows network error message, such as: . . .

Hello. I generated in the back end by hand (in C++ code, not with TableGen) some fancy assembly code using Inline ASM expressions and if I use 2 functions in my source code (but NOT just 1 function; I will not present the functions, but each requires me to generate an Inline ASM expression) I get this error at compilation (at scheduling): BB#0: derived from LLVM BB %entry

Hi. I want to do a cutomized points-to analysis on IR. Suppose that we have: *%91 = bitcast i8* %90 to %struct.demux_packet*, !dbg !2688* I want to store sth similar to %91 -> target of %90, which records the target of pointer named %91. How can I access the names (Here, %90 and %91)? I know that I can put the whole line for an instruction into a string, using the following code: *string str;*

Hi all, I am doing a project that requires counting the number of uses of a value only in all dominated blocks in a function. I checked the manual for llvm::User class, but only get this unsigned <http://llvm.org/test-doxygen/api/classunsigned.html> getNumUses <http://llvm.org/test-doxygen/api/classllvm_1_1Value.html#a380559e99b47632a34f74de7c1d03cc0> () const This gives me all the

Hi, I was trying to create a new *Store* instruction and inserting it to LLVM IR (.ll) file. I found the following constructor in LLVM Manual: StoreInst::StoreInst <http://llvm.org/docs/doxygen/html/classllvm_1_1StoreInst.html#aa2a72f9a51b317f5b4ab8695adf59025> (Value <http://llvm.org/docs/doxygen/html/classllvm_1_1Value.html> * Val, Value

Hi all, How can i find the instruction that uses the result of a load instruction. For example: %16 = load i32, i32* %ptr %add = add i32 4, %16 In this case, i would like to get the add instruction.
