Remove -Wa,-Av9a hack from <sys.mk> and relegate it to the places that need
...
it (kernel and libc).
The current version of the gas assembler in the tree (2.11.2) already
defaults to generating object files for "-Av9 -64", supporting V9
instructions in ELF64 object format. "-Av9a" is only needed for specific
parts of the NetBSD base sources, and not for all third-party code.

> cases. Totally rework this code to fix this bug *and* make it faster.

Change isnan() and isinf() to use a union to convert from double to
...
struct ieee_double, rather than a pointer cast. This seems to enable
GCC 2.95.3 to get the instruction dependencies right (the old one fell
foul of ANSI aliasing rules), and it also generates more sensible code in
general.
If this is the correct solution, it should be applied to the other ports.
If it's not, someone should come up with one that _is_ correct.

On the 68010, don't bother with the by-8-longwords loop, instead

only 16-bit align the region and use loop mode with longwords

on odd addresses would not be properly longword aligned.

On m68000, all code is compiled softfloat, so functions

that return floats must do so in integer registers, as the
pre-SVR4 ABI code did. So in these functions we ignore
__SVR4_ABI__ if __HAVE_68881__ is not also set.

b25c2304f3
I have no idea why this syscall wrapper does some very un-unix-like
...
argument prefrobbing, in particular, it computes max(addr, __minbrk)
and uses that. The code is like this even in the ancient libc/i386 tree,
back to the earliest rev 1.2. I did not see it Lite 1, but I'm not totally
sure what the random site I found was serving up.

* However, I do know that it should use jb and not jl.
