# The code used by the tests here encodes some breakpoints by using
# inline assembler. This will generate a SIGTRAP which will be caught
# by GDB. At that point the instruction pointer will point at the
# next instruction, and execution can continue without any problems.
# Some systems however (QNX Neutrino, Solaris) will adjust the
# instruction pointer to point at the breakpoint instruction instead.
# On these systems we cannot continue unless we skip it. This
# procedure takes care of that.
