If this is so, we treat the signal "in the usual way", it is, at the end we issue a "CONTINUE" instead of the needed SINGLESTEP. 2008-12-10 Juan Cespedes * summary.c: Fix "ltrace -o -c" * mkdist: rm -rf autom4te.cache * debian/control.ini: re-added armel and armeb 2008-12-10 Juan Cespedes * Release version 0.5.1 2008-12-10 Juan Cespedes * Patches from Anderson Lizardo and Riku Voipio: + Add generic support for arm targets + Save funtion arguments on arm + Add thumb instruction support + Add basic arm/eabi support + fix exec() testcase cleanup + fix memory corruption in clone() test + fix tracing child with "-p" option 2008-02-27 Luis Machado * sysdeps/linux-gnu/ppc/trace.c (arch_umovelong): New function. * sysdeps/linux-gnu/ppc/regs.c (get_instruction): New function.
