#47 fixed xpMMXreg macro (from x86-exceptions.h) not used, and appears wrong for darwin Gary Byers R. Matthew Emerson
Description

(lines 38--39 in lisp-kernel/x86-exceptions.h)

#define xpFPRvector(x) ((natural *)(&(UC_MCONTEXT(x)->__fs.__fpu_xmm0)))
#define xpMMXreg(x,n)  (xpFPRvector(x)[n])

The x87/mmx regs don't immediately follow the first xmm register in the darwin floating point state struct.

xpMMxreg appears to be unused at the moment, so it doesn't affect anything, but it seems like it ought to be corrected or deleted.

#48 fixed incremental search should wrap Gary Byers Jeremy Jones
Description

After incremental search fails, the next control-s should start searching at the beginning of the buffer.

#49 fixed meta-dot for structure accessors should work Gary Byers Jeremy Jones
Description

Currently, meta-dot on a structure accessor quietly fails. It should go to the defstruct, and ideally the cursor should be at the line that defines the slot.
