LLVM_DEFINITIONS used to be defined as set(LLVM_DEFINITIONS "-D__STDC_LIMIT_MACROS" "-D__STDC_CONSTANT_MACROS") Now it is defined as set(LLVM_DEFINITIONS " -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS") (note that it is no longer a cmake list but a string, and the string contains a leading space!) This causes CMake 3.1 to emit g++ -D

I made this change (not specifically changing from a list to a string, but changing from a hardcoded value to the value that was actually decided by cmake), and I checked that it works with cmake 2.8.12.2 which is the minimum version set in CMakeLists.txt. So if it doesn’t work with cmake 3.1/3.2 then that looks like something new that was introduced after 2.8.12.2. I’ll have a look at this

I noticed that runFunction (for MCJIT) is very limited. At the same time the interpreter already has a fairly generic way of calling functions from a pointer and a Function * (for description) using libffi. Would it make sense to pull that functionality out into a small support library and using it in MCJIT? As is runFunction isn't particularly usable. -- Johannes S. Mueller-Roemer, MSc Wiss.

Both Release and $CONFIG tblgen are built but the Release one is always used. At least with Visual C++ the Release tblgen is much faster than the Debug one. 2015-05-29 9:37 GMT+03:00 Mueller-Roemer, Johannes Sebastian < Johannes.Sebastian.Mueller-Roemer at igd.fraunhofer.de>: > Do they really allways put them into Release/bin or rather $<CONFIG>/bin? > > > > -- >

Hi Chris and everyone else, I just noticed that some of my builds broke due to commit 280013, as LLVM_INCLUDE_DIRS was renamed to LLVM_INCLUDE_DIR. In and of itself, not much of an issue as the fix is just to remove one character (in a couple of places). However, I would like to discuss if this rename is desirable at all. Sure, in-tree LLVM_INCLUDE_DIR is used everywhere, however not providing an

Indeed, mingw and pthreads have C++11 atomics, so building clang (with atomics) should be possible even in cross compilation. I have no idea what is the win from *not* using winpthreads, it is one small DLL file with BSD license. For context (does not matter to mingw as host for buiilding clang but matters for clang running with mingw environment), clang TLS implementation is not same as mingw so

That it’s faster is no surprise. Is the Release tblgen even built when you build in Debug mode? Otherwise this introduces the need to build Release before Debug. -- Johannes S.

I noticed some odd behavior with APFloat's convertFromString method. 1. If I pass the hex representation of the closest value to 0.1 (0x19999Ap-24), everything is fine and opOk is returned. However, if I pass the same value as a decimal string (0.10000002384185791015625), opInexact is set. 2. On the lower end of the scale, the smallest denormal 0x1p-149 returns opOk, but the

The new patch works fine, but considering the discussion on the CMake bug tracker, I'm would say that TO_NATIVE_PATH shouldn't be used at all. ________________________________________ From: Dan Liew [dan at su-root.co.uk] Sent: Wednesday, July 23, 2014 10:38 AM To: Mueller-Roemer, Johannes Sebastian Cc: llvmdev at cs.uiuc.edu Subject: Re: [LLVMdev] [patch] EXPORTED_SYMBOL_FILE using mingw

This is a problem with all floating point folding, not just with these operations.

… actually, now that I’m able double-check this, I’m quite surprised to find that we didn’t define fmax(+0,–0) in IEEE–754, which says [paraphrased]: minNum(x,y) is x if x < y, y if y < x, and the number if one is a number and the other is NaN. Otherwise, it is either x or y (this means results might differ among implementations). So I think your proposed semantics are perfectly

Hi, this is my first post to this list, so please excuse if submitting a patch without previous discussion is considered bad form or anything similar.
