Hi, I see the fail in gdb.dwarf2/implptr-optimized-out.exp in thumb mode (gdb) p p->f^M No symbol "p" in current context.^M (gdb) FAIL: gdb.dwarf2/implptr-optimized-out.exp: p p->f and the crash on powerpc64 (gdb) continue^M Continuing.^M ^M Program received signal SIGSEGV, Segmentation fault.^M 0x7d82100810000828 in ?? () The cause of both is that we incorrectly set attribute low_pc, since main isn't resolved to function start address on these targets. In this patch, we replace attributes name, low_pc and high_pc with MACRO_AT_func. The fail on thumb mode is fixed, and crash on powerpc64 is fixed too. gdb/testsuite: 2014-11-14 Yao Qi <yao@codesourcery.com> * gdb.dwarf2/implptr-optimized-out.exp (Dwarf::assemble): Replace name, low_pc and high_pc with MACRO_AT_func.
