Hello, Is there a script to update those test cases? I see mention of a sed script in the commit message but when I try it (see attached) on sed I get the following error: sed: file script line 2: invalid reference \3 on `s' command's RHS Did I lose something in a copy-paste? Is it not really a sed script? How do I run it? On Fri, Jan 19, 2018 at 9:15 AM, Daniel Neilson via

Hi Alexandre, The script uses extended-sed syntax, so you need to run sed with the -E option. For example, when preparing the patch I created a file ( script.sed ) containing all of the lines that I copied into the commit message. Then, I ran this bash one-liner from the test directory: for f in $(find . -name '*.ll'); do sed -E -i ‘.sedbak' -f script.sed $f; done When I was happy

Thanks, that worked like a charm except for the following: llvm generate: call void @llvm.memcpy.p3i8.p1i8.i64(i8 addrspace(3)* align 1 bitcast ([512 x float] addrspace(3)* @a_scratchpad to i8 addrspace(3)*), i8 addrspace(1)* align 1 %0, i64 2048, i1 false) And we expected: call void @llvm.memcpy.p3i8.p1i8.i64(i8 addrspace(3)* bitcast ([512 x float] addrspace(3)* [[SPM0]] to i8

Yes, all that is correct. My question is more a long term question: why do the .ll printer specify the alignment if it is equivalent to the default one? That is, it seems the sed script expect the printer to not specify it (this would match the load/store behavior), but the ll-printer does specify it, which either means the printer is not ideal on this case and I should fix it, or in this case

Hi Alexandre, Before the change you would have been expecting one of the following, correct? a) call void @llvm.memcpy.p3i8.p1i8.i64(i8 addrspace(3)* bitcast ([512 x float] addrspace(3)* [[SPM0]] to i8 addrspace(3)*), i8 addrspace(1)* [[APTR]], i64 2048, i32 0, i1 false) b) call void @llvm.memcpy.p3i8.p1i8.i64(i8 addrspace(3)* bitcast ([512 x float] addrspace(3)* [[SPM0]] to i8 addrspace(3)*), i8

Good question. AFAIK, the IR-printer doesn’t understand the semantics of parameter attributes. In this case, it only knows that there is an attribute on the parameter that is integer valued (with value 1) and that has the name “align”, so it prints it out. If we don’t want it printing out ‘align 1’ then it’s up to us to not set the alignment parameter attribute to a value if that value would be 1.

Hi Geoff, Nothing in that backtrace leaps out at me. Based on the stack trace and description my first guess would be a clang misconfiguration rather than a JIT bug. How is that clang invocation being made? Is it from inside a callback from ORC, or is it before you add your module to the JIT? -- Lang.

Greetings, Lang and other JITters, Last week I moved our Orc v2-based app from top-of-tree to the new 11.x branch, and it no longer handles C++ code containing OpenMP directives correctly. More specifically, if I JIT compile a function containing OpenMP parallel/for pragmas, using a release version of LLVM, the code compiles and seems to work, but if I try to write the module's bitcode to

Hi, That patch was from an ongoing effort to consolidate OpenMP generation in clang. If memory serves the implementation there is still a little incomplete. It's supposed to use types from OMPConstants rather than ones it defined itself and the methods used to create the functions shouldn't need to be static. However attempting this caused a lot of errors so there might be an underlying

Thanks, Joseph and Johannes. I have not merged in anything, I am using the code from the repository as is. What is this -debug-only option, and to whom would I pass it? I am running our own JIT application, which uses clang to compile modules on the fly via clang::CompilerInstance::ExecuteAction(). Working on the assumption that there is a mismatch in the declared type of an OpenMP runtime

As part of our automated testing, I'm running make check-all to watch for failures. One of my builds uses the --enable-optimized option to configure. When I build the latest trunk, I'm now seeing 18 failing tests: Clang :: Preprocessor/macro_paste_c_block_comment.c LLVM :: CodeGen/ARM/2011-05-04-MultipleLandingPadSuccs.ll LLVM :: CodeGen/ARM/2011-11-14-EarlyClobber.ll LLVM

Yep, it happens three times, then crashes afterwards, since I removed the assert... arg 0: expected %struct.ident_t* got %struct.ident_t.21* value @0 = private unnamed_addr global %struct.ident_t.21 { i32 0, i32 514, i32 0, i32 0, i8* getelementptr inbounds ([23 x i8], [23 x i8]* @.str, i32 0, i32 0) }, align 8 arg 0: expected %struct.ident_t* got %struct.ident_t.21* value @1 = private

Yeah, I remember encountering that error before when getting it to pass the libomp test suite. If you have a struct named "ident_t" somewhere the compiler will rename it because of the conflict with the runtime declaration. This should be solved by casting the usage to the function type found in the definition (i.e. bitcasting a struct.ident_t.21 to struct.ident_t) which solved the

Hi, Some random sample of VS warning: Lot of 64 bits conversions: AsmPrinter.cpp ..\..\lib\CodeGen\AsmPrinter.cpp(277) : warning C4244: 'initializing' : conversion from 'uint64_t' to 'unsigned int', possible loss of data ..\..\lib\CodeGen\AsmPrinter.cpp(614) : warning C4244: 'argument' : conversion from 'uint64_t' to 'int', possible loss of data

Greetings, I am having trouble getting the Kaleidoscope example to build from tutorial #3 on Mac OS X 10.6.2. I didn't have too much trouble getting llvm-2.6 and llvm-gcc-frontend to build. Thanks for the help. Here are the steps I followed: Environment variables for build export LLVMOBJDIR=/opt/llvm export TARGETOPTIONS='--with-arch=nocona --with-tune=generic' export

So, when performing expression evaluation, lldb trips over an assert in clang/lib/AST/RecordLayoutBuilder because ExternalFieldOffsets doesn't contain a FieldDecl that updateExternalFieldOffset expected. I found that the assert occurs when both static and non-static member variables are present. For instance, with the following, the lldb command 'expr my_test.length()' does not

There are LLVM 2.9 RC1 pre-release tarballs source available. You can find them here: http://llvm.org/pre-releases/2.9/ Please download them, build them, and compile things to your heart's content. And most importantly file a bunch of bug reports. :-) Share and enjoy! -bw

Hi, I've bootstrapped llvm/clang from svn-trunk on powerpc-darwin8 (g++-4.0.1), and have the following test results to share. Summary below, full log at: http://www.csl.cornell.edu/~fang/sw/llvm/r146586-powerpc-darwin8-results.txt The only edits required were those I posted to llvm-commits yesterday (re: "some missing clang libs"). And I also edited LitConfig.py to point to

FYI, this turned out to be an error of omission in LLDB in SymbolFileDWARF, because the case of a non-defining external (i.e. a static member variable) wasn't being handled with a variable lookup to dig up the location.
