similar to: accessing stack frame after returning from the function

Let in a program a variable 'x' is tainted. There is an assignment 'y=x' where y is untainted. How to check the taintflow in the output or data flow graph ? Any suggestions? Thank you. Have a great day. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20190912/5bb3655c/attachment.html>

hello, I am trying to build LLVM with default options. I am getting the following error message after make.

Hello, I have studied register allocation in theoretical aspects and exploring the same in the implementation level. I need a minimal testcase for register spilling to analyze spilling procedure in llvm. I tried with a testcase taking 20 variables but all the 20 variables are getting stored in the stack using %rbp. Maybe my live variable analysis is wrong. Please help me with a minimal testcase

Various options for reducing memory usage when building LLVM: * Don't use bfd-ld, at least use gold, probably use lld if you have it available * With Ninja and/or CMake there's some way to specify the maximum number of concurrent linkactions - lower this to fit in your available memory * If you're building with debug info: Use Split DWARF On Thu, Jan 2, 2020 at 5:21 AM Kókai Péter

The last time this came up, we agreed something should be done to fix the defaults, but nobody picked it up and ran with it. I think there was consensus, it just needs legwork now.

But if you think it helps, I can compile gcc 4.1 and give it a shot. >> Compile flags: >> DEFINES +=

Hi Ralph, Thanks very much - I will try your suggestions and let you know wether that helped or not Peter Am 15.10.2023 um 14:33 schrieb Ralph Boehme: > On 10/14/23 23:43, Peter Koch via samba wrote: >> It must be possible to tell the build-system that smbscardd needs >> -lcrypto >> Please let me know how. > > ./source3/wscript:???

Hi , I would like to know if there is any way to reorder functions in the object file in order to improve code locality by implementing subsections .text.hot. GCC controls this behavior with '-f(no)-reorder-functions' flag, is there any way to do so in clang? Regards, Priyanka -------------- next part -------------- An HTML attachment was scrubbed... URL:

I used libguestfs for transferring files from host OS to guest VM. It worked successfully. But since the tool being very huge and has many more functionalities, which my project doesn't need. I just want to use the functionality provided by virt-copy-in. Can you please tell where will I get the code which virt-copy-in uses internally? I have libguestfs folder. In that which files are used for

Hi, I build llvm+clang+lldb 3.7 successfully on centos7, and lldb -p PID works pretty well. However when I tried lldb -c corefile executable_bin, lldb itself core dumpped. Attached the following core info which is debugged by gdb: [root at dn-cn-controller-4fbd4 data1]# lldb -c a.corefile /usr/local/myproject/bin/cnode *(lldb) target create "/usr/local/myproject/bin/cnode" --core

I want to transfer files between host and guest. What are the ways to transfer these files? Is libguestfs the only way to transfer files between host and guest? Regards, Priyanka Naik

Hello, I've migrated successfully samba3 to samba4 by using samba-tool.

Hi, Is it possible to add a spill code (a pair of store /load ) to the machinecode in a pass before the instruction emitter? If so, how can I calculate the address (offset to the sp) for the spill store/load instructions? Thanks -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all, Sorry to bother those not interested. I am a newbie to LLVM. I have a problem on allocating additional stack slot for checkpointing. However, I have no idea on how to allocate redundant stack slot in llvm. Any suggestions? Thanks, Ray -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello Richard, One more question, you mentioned that "hot plugging" is supported from *CentOS 7 *and gave me a link. That link says "In libguestfs ≥ 1.20, you may add drives and remove after calling "guestfs_launch" <http://libguestfs.org/guestfs.3.html#guestfs_launch>. There are some restrictions, see below. This is called*hotplugging*." When I executed

Dear all, I don't get how llvm handles functions with __attribute__((noreturn)). It seems that LR register is backed up on the stack whilst it will never be used to return from a 'noreturn' function. I have this problem with a home-made backend but it seems that ARM flavour of clang has same behaviour. By the way, SP is also saved, I don't understand why. Is there a syntax error
