This changes many tests to use 'require' when checking target_info. In a few spots, the require is hoisted to the top of the file, to avoid doing any extra work when the test is going to be skipped anyway.

# After PowerPC Linux kernel commit:

# commit: 0138ba5783ae0dcc799ad401a1e8ac8333790df9
|
|
# powerpc/64/signal: Balance return predictor
|
|
# stack in signal trampoline.
|
|
#
|
|
# The kernel places an additional brctl instruction
|
|
# in the vdso to call the user handler.
|
|
#
|
|
# And then this commit:
|
|
#
|
|
# commit 24321ac668e452a4942598533d267805f291fdc9
|
|
# powerpc/64/signal: Fix regression in
|
|
# __kernel_sigtramp_rt64() semantics
|
|
#
|
|
# updates the semantics of __kernel_sigtramp_rt64().
|
|
# It added a new symbol to serve as a jump target from
|
|
# the kernel to the trampoline.
|
|
#
|
|
# The net result of these changes is that gdb stops
|
|
# at __kernel_start_sigtramp_rt64. Need to do one
|
|
# more stepi to reach the expected location in the user
|
|
# signal handler.
