include bsd.own.mk early on, and if !alpha or if !ELF_TOOLCHAIN,
build c++rt0.o. ELF alphas don't use the 'normal' C++ runtime startup
routines. Eventually, there should be better ways to distinguish what
toolchain and object format is in use, and the Alpha C++ startup code
changes should be merged with that used by the other ports.
for NOEXEC and NOSUID, and make sure the interpreter file is executable.
The mount point checks are done because, even though the interpreter
is not the program being 'executed', code from the interpreter is being
executed, and so the mount point's flags should be respected.
the make to not fail even if the installations failed, which is wrong.
If the installations fail (e.g. because the target directory does not
exist), the whole install should fail, so that the user knows to
create the appropriate directories.
exceptions, which puts the address of the instruction we faulted
on in a different location. Copy it and handle as we normally would,
restoring the saved PC before returning.
The FPE should probably be reworked to take advantage of the 68LC040's
precalculated effective address, at some point.
to signal that the build is happening on a machine with an ELF
toolchain. This is temporary, until a better toolchain-recognition
scheme is worked out.
(1) bsd.prog.mk already includes bsd.subdir.mk, and
(2) including bsd.subdir.mk first screws up the clean/cleandir targets
in such a way that the program's objects don't get blown away
when you make clean.
- Only pass user trace traps and breakpoints on to trap().
Gets rid of some hair in the trace/breakpoint trap cases.
- Before entering the debugger, switch to a temporary
stack so that the debugger can alter the stack pointer.
- Add glue for KGDB (still not complete).
Some other minor cleanup:
- Protect against some bad pointer derefs.
- Be more a little more verbose when a fatal trap
occurs to aid debugging.
- Only pass user trace traps and breakpoints on to trap().
- Before entering the debugger, switch to a temporary
stack so that the debugger can alter the stack pointer.
- Add glue for KGDB (still not complete).
Clearly mark the MMU enable trampoline code.
