Good morning. I don't understand relation between output.log and error.log. It seems all LLVM libraries are not found on linking opt.exe. Please show us logs with command lines with make VERBOSE=1 It would be better only then to touch a few files. (eg. lib/Transforms/Scalar/GVN.cpp) The warning of --export-dynamic might be harmless, and you may add the option --enable-auto-import IIRC

Given that this is compiled with -O0, would there a way to skip the Optimization of the Type-legalized selection DAG? It's fine until it optimizes the Type-legalized selection DAG into the Optimized Type-legalized selection DAG.

Hi, If x is a local variable, it will be stored on the stack. So you need an alloca for it: %x = alloca i8 ; <i8*> Then you can just perform a store: Store i8* %x, i8 0 Cheers, James > -----Original Message----- > From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] > On Behalf Of leledumbo > Sent: 20 October 2010 14:39 > To: llvmdev at

How can I generate LLVM IR for both logical NEG (!)? For example, if I have Int32Ty a, For the bitwise NEG(~): c = ~a ; I can use the following API from LLVM: BinaryOperator *neg = BinaryOperator::CreateNeg(nbits, "bitwiseNEG", insertBefore); How, if I want to generate logical NEG: c = !a; what should I do for this?

The current btrfs support did not handled multiple stripes stored in chunk items, hence skipping the physical addresses that were needed to do the mapping. Besides, the chunk tree may contain DEV_ITEM keys which store information on all of the underlying block devices, so we must skip them instead of finishing lookup. The bug was reproduced with btrfs-progs v4.2.2. Cc: Gene Cumm <gene.cumm

Hi, Dan I add "not" instruction support in PTXInstrInfo.td as you suggested before. multiclass PTX_LOGIC_2OP<string opcstr,PatFrag opnode> { ... } Now I am trying to write test case for logic and shift operations. But I have a trouble in mapping LLVM IR to PTX IR for "not" instruction. The test case I wrote is, define ptx_device i16 @t4_u16(i16 %x) { ; CHECK:

Thanks, Bruce. So, what is the easiest way to check if there is any bit set to 1 in a <N x i1> vector type? I used bitcast instruction to cast it into "iN" first and them compare iN to 0. Do you have a better way to do it? Thanks again. On Fri, Apr 10, 2015 at 5:22 PM, Bruce Hoult <bruce at hoult.org> wrote: > LLVM doesn't have a "logical neg" (or
