similar to: lit conditional compilation/checking?

As of Visual Studio 2015, natvis files can be included as part of individual projects <http://blogs.msdn.com/b/vcblog/archive/2015/09/28/debug-visualizers-in-visual-c-2015.aspx>, a much better method than manually copying the file to an specific directory in %USERPROFILE%. I think it should be included in one of the CMakeLists.txt files, does anybody know how I can add it? Sincerely,

That makes sense. Someone should stick it in the coding standards? it's just thankless work Absolutely, but since slow compile times (can) nuke my productivity, I may move some code out of headers. Sincerely, Alexander Riccio -- "Change the world or go home." about.me/ariccio <http://about.me/ariccio> If left to my own devices, I will build more. ⁂ On Wed, Feb 10, 2016

While investigating compile times, I noticed that there's no information in the LLVM coding standards about code in headers. Many LLVM/Clang headers have lots of complex code in headers - I'm specifically looking at the Static Analyzer projects (seemingly slowest compile times, biggest hinderance to my productivity) - that probably doesn't need to be there. Nobody likes slow compile

llvm::sys::fs::make_absolute converts its first parameter (const Twine &current_directory) to StringRef p(path.data(), path.size()), and then passes that StringRef to several functions (path::has_root_directory, path::has_root_name, and path::append) that accept Twines as parameters. Since llvm::StringRef can implicitly convert to an llvm::Twine, p converts to a bunch of Twine temporaries. In

Not sure that works.  I had that initially: auto cf = IRB.CreateICmpULT(Incr, ConstantInt::get(Int8Ty, 1)); auto carry = IRB.CreateZExt(cf, Int8Ty); Incr = IRB.CreateAdd(Incr, carry); it makes no difference to the generated assembly

My 2c: I don’t think that we can agree to abstract code guidelines without knowing what it means in practice for the codebase. If you’re interested in this, please include a diff

Hello, I have an optimisation issue in an llvm IR pass - the issue being that unnecessary instructions are generated in the final assembly (with -O3). I want to create the following assembly snippet: mov dl,BYTE PTR [rsi+rdi*1] add dl,0x1 adc dl,0x0 mov BYTE PTR [rsi+rdi*1],dl however what is created is (variant #1): mov dl,BYTE PTR [rsi+rdx*1] add dl,0x1 cmp

So I manage to get clang's colored output through ninja simply by force (CMAKE_CXX_FLAGS=-fcolor-diagnostics), which isn't ideal (if I were to pipe ninja's output to a file it'd still have color escapes, etc) but it works. But I haven't found a similar solution for FileCheck & I'm wondering has anyone already solved this problem for themselves - if so, how? if not,

I just want to update test/Transforms/LowerSwitch/feature.ll that already uses grep. It uses grep + count, probably due to shorter construction. -Stepan.

Is there a way to do this with llvm-lit, i.e., use the equivalent of backticks? foo takes a single argument, but doesn't read from stdin. // RUN foo some_arg > %t; FileCheck %s < %t // RUN foo `cat %t` | FileCheck --check-prefix=INVERSE // CHECK: {{^[0-9]+$}} // INVERSE: some_arg thanks... don -------------- next part -------------- An HTML attachment was scrubbed...

llvm-lit is already put into <output-tree>/bin by CMake. There is a CMake target called `llvm-lit` that will generate the <output-dir>/bin/llvm-lit script. If you built only a few specific llvm targets such as FileCheck, etc then you may need to run this lit target manually. If you just run "ninja" for example, or "ninja check-llvm", it's automatically

Hi all, I've got https://reviews.llvm.org/D37756 up for review currently which simplifies a lot of the logic in our lit config files. For most people, this will be completely transparent and "just work", but it breaks one workflow that people should be aware of. Problem: If you run lit by putting llvm-config in your path and then running <source-root>/utils/lit/lit.py

Hi all, quite a few tests use the pattern "2>&1 | FileCheck %s". AFAIK how stdout and stderr are merged into a single character stream is undefined and depends e.g. on whether stdout is buffered. I think we are often saved by the fact that standard output is written only at the end of the program and stderr is unbuffered, i.e. always written before stdout. A lot of tests disable

Hi all, Can anybody give a tutorial about how to use llvm-lit tool? I copy and revise Makefile and lit.cfg etc from clang to my project. However, when I run make test it always seem unable to find the FileCheck tool correctly. How can I fix it? Can anybody add test feature to llvm/project/sample?

Use of 'grep' in tests is an endless source of problems, and we are

Hi, I am observing a deadlock with llvm-lit on windows 7. When I attached a debugger, the communicate() call is blocked. In file utils/lit/lit/TestRunner.py > # FIXME: There is probably still deadlock potential here. Yawn. > procData = [None] * len(procs) > procData[-1] = procs[-1].communicate() I am invoking python directly on windows to run the unit tests.

Hi, I have a project which uses llvm, but is (at least not yet) a contribution / not in the source tree of llvm. Is it a good idea (e.g. instead of using boost test framework) to use the llvm testsuite related tools in this case? Alex

Hi all. I found that if you want to use grep with escape characters in lit, you should pass it within the double slash (\\). Since the first one is captured by python scripts and the second one by grep. E.g. if you want to capture "grep icmp ule" you should pass "grep icmp\\ ule" So I'm going to commit the test with strings like this. How stable this feature in lit?

I'm trying to put together some tests for the optimization bisecting feature I'm working on and I've come across a stumbling block trying to accomplish something in a lit test. I've got an IR file with some simple functions, one of which includes a call to another function that will be inlined during optimization. I can use this to manually test my new OptBisect class by invoking
