Hi guys, I am following this[1] tutorial to install clang. However, I have made a small change in the configure command, and I am running it with '--enable-optimized' option to avoid the debug build. I am getting the errors (given at the end) related to *undeclared identifiers '__NR_*'*. Can someone please provide some input about how to tackle this issue? On my other machine, I

Hello All, I build LLVM source code version 3.2 from SVN repository. After I build source code of LLVM include "compiler-rt"(Compiler-rt at revision 158057. ) and "clang" are represent an error as below. make[5]: Entering directory `/san01/home/chatsiri/workspacecpp/llvm-svn/projects/compiler-rt' COMPILE: clang_linux/asan-x86_64/x86_64:

Hello, I'm quite new to LLVM, but I'm interested in memory sanitizer. The petty thing is, that 32bit addressing on Linux is not supported. Thus I tried to take the latest version of the software and to modify it, using Ubuntu 16.04 as operating system. Given the example example.c: #include <stdio.h> #include <stdlib.h> int main(int argc, char **argv) { int *a = (int

Hi all, I experienced some test failures under Linux, probably caused by r232936: In the test SanitizerCommon-Unit :: Sanitizer-i386-Test/MemoryMappingLayout.CodeRange the temporary test file was opened write-only, but was read from, what subsequently failed: Note: Google Test filter = MemoryMappingLayout.CodeRange [==========] Running 1 test from 1 test case.

Hi, I see that ENABLE_WERROR is being set to off (the default value) in the config.log in the llvm build. However on grepping for WERROR in the compiler-rt folder I get the following output: pranav at pranav:~/smack-project/llvm-3.4/src/projects/compiler-rt$ grep -Rin WERROR * lib/asan/tests/CMakeLists.txt:38: -Werror lib/asan/asan_malloc_mac.cc:253:// This function is currently unused, and we

In the same way that llvm does not depend on clang, compiler-rt

Hi, In sanitizer code we have two notions of stack unwinders: fast and slow. [1] In the context of sanitizers, stack unwinding is most often for printing error reports that include a stack trace. I am currently trying to fix an issue that is related to some platforms (Darwin) only supporting the fast unwinder, but calling code not being aware of that possibility. My mental model was that

Hi. I'm using llvm DataFlowSanitizer. I add such code in library libtiff. dfsan_label lt_label = dfsan_create_label("buf_offset", 0); dfsan_set_label(lt_label, (unsigned char *)buf, size); But when i compile libtiff with "-fsanitize=dataflow" option, then there is an error as follows: ../libtiff/libtiff.so.5.2.5: undefined reference to `dfs$jbg_enc_init'

Dear Alexey, Yes I am sure that the llvm, clang and compiler-rt are synced to the same version. I downloaded them all from git http://llvm.org/docs/GettingStarted.html#git-mirror I think I need compiler-rt for my project but I'll verify it again to see if I can proceed without it. You are correct that compiler-rt is compiled with the just built clang. The complete command that gives an error

yes I think that is correct. I wrote a simple program to print if sizeof(uintptr_t) != sizeof(unsigned char *) and when I compile with gcc -m64 and execute it on a 64-bit host (that is different from the 32-bit laptop on which I originally compiled the program), it says the sizes are not equal.

This morning I'm seeing 4 new sanitizer failures in SanitizerCommon-Unit (compared to a couple of days ago, when I didn't see these) - perhaps related to recent library refactoring?
