[RFC] Use target vector inheritance for GNU/Linux

Daniel Jacobowitz
2004-12-05T18:46:19Z

This patch converts all GNU/Linux targets to inf-ptrace.c and target vector
inheritance. I was going to do them one at a time, but because the common
native-specific code is so large for GNU/Linux, it was too awkward.

A new function, linux_target, is added to linux-nat.c. Then any GNU/Linux
target can call it, and pass the result to add_target - after specializing
whatever methods it needs to. Sometimes it's necessary to specialize a
method between inf_ptrace_target and linux_target, so it accepts an optional
argument. This wouldn't be necessary if all target methods took a
target_ops parameter, so they could call the overridden method.

One use of deprecated_child_ops was particularly thorny, so I updated the
to_follow_fork method to take a struct target_ops and push the correct
target. I made to_follow_fork a non-inherited method, like to_xfer_partial.

This patch leaves some completely dead macros in config/nm-linux.h, and some
mostly-but-not-quite dead macros in various other nm-files. I'll be back.
I didn't want to change more than absolutely necessary, once I was committed
to doing all targets. My next step will be merging the two target vectors
in linux-nat.c.

I've tested this patch with the full testsuite on x86_64-linux and
i386-linux, partial testsuite on ia64-linux [it gets hung up in an
infinite loop in sigaltstack.exp with or without the patch], and smoke
testing on s390x [the machine I was using didn't have expect].

Comments? Proofreading? I'm going to let this sit for a couple of days,
because (while mechanical) it's very large - I think I got everything, but
since I don't have the resources to test on every single GNU/Linux native
target, I can't be sure.
