Thank you for suggestions. I've prepared few patches:
ElfXX_Chdr-build-fixup.diff - tinfl is moved to m_debuginfo, checking for Elf32/64_Chdr structs is placed into "configure" and line endings in tinfl.c are converted to Unix style. Elf32/64_Chdr, SHF_COMPRESSED and ELFCOMPRESS_ZLIB come from libc (<elf.h>) and exist only in newer versions of libc. These structures/constants are not present in Kernel, so I didn't move them to vki. We can place them to separate header or pub_tool_libcbase.h, if you think it's more appropriate. zdebug-support.diff - support for .zdebug sections is added to readelf.c. Three kinds of compressed debug sections are supported by Binutils 2.26 (zlib, zlib-gnu and zlib-gabi) and I have tested Valgrind with all of them on MIPS/X86 Linux. According to the manual (https://gcc.gnu.org/onlinedocs/gcc/Debugging- Options.html), GCC should support -gz=zlib and -gz=zlib-gnu options for generating compressed debug sections, but I haven't succeeded to set up the environment in which it works. I've written two simple Memchek tests (compressed_sections_test.diff) which use these options, but they are not tested properly. The order of applying patches (after applying compressed-dwarf- support.diff and tinfl-modifications.diff) : patch -p1 < ElfXX_Chdr-build-fixup.diff patch -p1 < zdebug-support.diff patch -p1 < compressed_sections_test.diff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1567219 Title: Valgrind does not support compressed debug info To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1567219/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
