I find some gdb.python tests fail on arm-none-eabi target, because the tests assume that memory on address 0x is inaccessible. Some tests (in gdb.base) are aware of this, so do a "x 0" check first. However, the code is copy-n-paste. This patch is to move the "x 0" check to a procedure in lib/gdb.exp, and get needed tests call it. The original code matches pattern "0x0:\[ \t\]*Error accessing memory address 0x0\r\n$gdb_prompt $", but I remove it from the new proc is_address_zero_readable, because GDB doesn't emit such message any more. gdb/testsuite: 2014-08-09 Yao Qi <yao@codesourcery.com> * gdb.base/display.exp: Invoke is_address_zero_readable. * gdb.guile/scm-value.exp (test_value_in_inferior): Likewise. * gdb.python/py-value.exp (test_value_in_inferior): Likewise. * gdb.base/hbreak-unmapped.exp: Return if is_address_zero_readable returns true. * gdb.base/signest.exp: Likewise. * gdb.base/signull.exp: Likewise. * gdb.base/sigbpt.exp: Likewise. * gdb.guile/scm-disasm.exp: Do the test if is_address_zero_readable returns false. * gdb.guile/scm-pretty-print.exp (run_lang_tests): Likewise. * gdb.python/py-arch.exp: Likewise. * gdb.python/py-prettyprint.exp (run_lang_tests): Likewise. * lib/gdb.exp (is_address_zero_readable): New proc.
