== GDB == * Ongoing work on glibc patch to add ARM unwind tables to system call stubs; ran into design problems that look difficult to fix.
* As an alternative, started work on a GDB patch to recognize glibc system call assembler stubs via code-scanning; this should allow alloc unwinding in the absence of debug info for current libc code. * Analyzed bug #728216 (GDB fails to get a valid backtrace while debugging a Webkit SIGSEGV) and resolved as invalid; the fault occurs within JIT-generated code where unwinding is impossible. == Misc == * Made travel arrangements for Linaro Summit in Budapest Mit freundlichen Gruessen / Best Regards Ulrich Weigand -- Dr. Ulrich Weigand | Phone: +49-7031/16-3727 STSM, GNU compiler and toolchain for Linux on System z and Cell/B.E.
