I believe https://reviews.llvm.org/D44449 <https://reviews.llvm.org/D44449> should fix this issue.

Hi, While dogfooding our lldb based IDE on Linux, I am seeing a lot of variable evaluation errors related to DW_TAG_member which prevents us from release the IDE. Can anyone help to confirm if they are known issues? If not, any information you need to troubleshoot this issue? Here is one example: (lldb) fr v *error: biggrep_master_server_async 0x10b9a91a: DW_TAG_member '_M_pod_data'

If you're going to use clang built binaries with lldb, you'll want to pass -fstandalone-debug - this is the default on platforms where lldb is the primary debugger (Darwin and freebsd) Not sure if that is the problem you are seeing, but will be a problem sooner or later On Mar 26, 2016 4:16 PM, "Jeffrey Tan via llvm-dev" <llvm-dev at lists.llvm.org> wrote: > Hi, >

Thanks David. I meant to send to lldb maillist, but glad to hear response here. Our binary is built from gcc: String dump of section '.comment': [ 1] GCC: (GNU) 4.9.x-google 20150123 (prerelease) Is there any similar flags we should use? By doing "strings -a [binary] | grep -i gcc", I found the following flags being used: GNU C++ 4.9.x-google 20150123 (prerelease)

'-DCMAKE_CXX_FLAGS=-fno-omit-frame-pointer -Wno-maybe-uninitialized -fPIC -fPIE' -- The C compiler identification is GNU 4.8.1 -- The CXX compiler identification is GNU 4.8.1 -- Check for working C compiler: /home/engshare/third-party2/gcc/4.8.1/centos6-native/cc6c9dc/bin/gcc -- Check for working C compiler: /home/engshare/third-party2/gcc/4.8.1/centos6-native/cc6c9dc/bin/gcc -- works --

Hey Pete, I also tried CMAKE_CXX_FLAGS_RELEASE with the same effect. On Mon, Jul 20, 2015, at 09:34 AM, Pete Cooper wrote: > Hi Adrian > > I’m not sure if the CMAKE_CXX_FLAGS is used in LLVM.

I regularly use '-DCMAKE_CXX_FLAGS' when configuring CLang/LLVM to distinguish my builds (Alpha/Beta/Final) or to build custom versions, usually by adding additional '-D' flags, but I discovered I had to add the ':STRING' qualifier to it when invoking 'cmake'. With 'gmake' this is equivalent to '--with-extra-options="whatever flags":

This is just for compiler-rt. The reason for having -fno-omit-frame-pointer is that tools like https://perf.wiki.kernel.org/index.php/Main_Page would work on ASAN binaries.

Hi, I have a case that for pointer with address space attribute, pointer arithmetic is not work. For example, -bash-4.4$ cat test.c #define __user __attribute__((address_space(1))) void __user * test(void __user *arg) { #ifdef ADD return arg + 4; #else return arg; #endif } -bash-4.4$ -bash-4.4$ clang -g -c test.c -bash-4.4$ clang -g -c -DADD test.c clang-10: ../lib/IR/Instructions.cpp:2749:

I forgot the -DADD flag earlier but the result did not change: https://godbolt.org/z/NPcn22 ________________________________________ From: llvm-dev <llvm-dev-bounces at lists.llvm.org> on behalf of Doerfert, Johannes via llvm-dev <llvm-dev at lists.llvm.org> Sent: Wednesday, October 30, 2019 20:18 To: LLVM Developers Mailing List; Y Song Cc: Alexei Starovoitov Subject: Re: [llvm-dev]

Thanks for the detailed info! The problem was that I tried without assertions and didn't inspect the IR closely as it contained this, for now, illegal instruction: %6 = bitcast i8* %5 to i8 addrspace(1)* This is clearly a clang error. I suggest opening a bug report, or sending the reproducer to cfe-dev at llvm.lists.org so someone will take a look that has more clang experience. @Matt Do

Hi everyone, TL;DR: With current pending patches applied in compiler-rt and llvm, and trunk clang, you can build your application with XRay tracing enabled on Linux with tracing enabled before main starts, and logging stops when the main thread exits. Just a quick update, I have some patches under review that when applied cleanly to LLVM and compiler-rt allows for building applications with XRay

Dear R Experts, I am having some trouble creating a variable in R. I have data on self-placement of voters, their placement of parties, and which party they feel closest to. The data is structured like this: Party_Close lrplaceself lrplaceParty1 lrplaceParty2 ... party1 2 4 5 party2 5 6 4 party1 6 2 1 etc... I want to format the data set so it looks like this: Party_Close

Attached please find unified diffs against Samba 2.0.6. I'm hoping that others will find it useful and that it may even find its way into Samba 2.0.7 This patch does two things: - Modifies the handling of the 'netbios name' parameter so that standard_sub_basic() is run on its value when the 'netbios name' parameter is processed. This has to be done this way because

Thanks Teresa Yes it is astar, happen to send a tar of the sources but they are just copies from the spec distribution The ld command is: GNU ld (GNU Binutils) 2.29.1 Thanks for the guidance on path names. The prefix-replace just effects the string written to the object files right? So we could post-process that file with other tools as well, correct? Thanks again --david From: Teresa Johnson

Here is a bunch of small patches to make fish/ build with most warnings enabled: [1/9] edit.c: avoid warning about signed/unsigned comparison [2/9] fish.c: avoid warnings [3/9] tilde.c: avoid a warning [4/9] fish.c: avoid "assignment discards qualifiers..." warning [5/9] fish.c: avoid signed/unsigned-comparison warning [6/9] fish.c: don't perform arithmetic on void*

These patches first make src/ warning free, and then turn on the strict warning options. 75 0001-build-suppress-an-ignored-write-return-value-warning.patch 38 0002-build-suppress-an-ignored-dup-return-value-warning.patch 27 0003-generator.ml-suppress-signed-unsigned-compare-warnin.patch 48 0004-build-don-t-perform-arithmetic-on-void-pointers.patch 30
