This needs to be applied as well.

Hello, In one of the loop transformations I am developing, I need to convert eq and neq loop latch condition into less than or greater than depending on the control flow. The problem is that CmpInst::ICMP_EQ and CmpInst::ICMP_NE are neither signed nor unsigned in LLVM. Also, I did not find a way to find out if the integer operands of the CmpInst are signed or unsigned. Apparently, LLVM does

Let's come back to this. The attached patch decouples InstSimplify from the alias analysis and provides the conservative logic for when pointers are not

Hello , I have build llvm from release_38 branch ( only llvm and clang ) and install it. My DYLD_LIBRARY_PATH points to installation-directory/lib.

Hello, I'm working on integrating the MachinePipeliner.cpp pass into our VLIW backend, and so far we've managed to get it working with some nice speedups. Unlike Hexagon however, our backend doesn't generate hardware loop instructions and so all our loops are a combination of induction variables, comparisons and branches. So when it came to implementing reduceLoopCount for our

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

That patch had to be removed as it broke SPEC. I've since updated the patch, and am ready to break spec again. ;-) This patch adds constant folding of multidimensional arrays even when the index to those

How do you determine if a shift is signed or not? ashr = always signed? lshr = always unsigned? shl = always signed? The CmpInst has the "isSigned()" function, but it appears that every other Instruction I've looked at doesn't seem to have this. -------------- next part -------------- An HTML attachment was scrubbed...

Hi all, I am having some some trouble with LLVM 3.8... I built it with GCC 4.8.2 with cmake and no special CXX/C flags. That means in case of GCC that RTTI is switched on, I believe.

Hello Asteriskers, :-) We're trying to set up an outbound notification calling for system alerts with Asterisk 1.4.0. We generate a call file in /var/spool/asterisk/outgoing and the outbound call is originated through Zap/1 (Sangoma A200D to a Canadian POTS line). The problem is that Asterisk does not wait for the other side to answer before it starts playing the message. So the
