320 The SVR4 reference port C compiler uses the following register numbers
321 in its Dwarf output code:
322 0 for %eax (gnu regno = 0)
323 1 for %ecx (gnu regno = 2)
324 2 for %edx (gnu regno = 1)
325 3 for %ebx (gnu regno = 3)
326 4 for %esp (gnu regno = 7)
327 5 for %ebp (gnu regno = 6)
328 6 for %esi (gnu regno = 4)
329 7 for %edi (gnu regno = 5)
330 The following three DWARF register numbers are never generated by
331 the SVR4 C compiler or by the GNU compilers, but SDB on x86/svr4
332 believes these numbers have these meanings.
333 8 for %eip (no gnu equivalent)
334 9 for %eflags (no gnu equivalent)
335 10 for %trapno (no gnu equivalent)
336 It is not at all clear how we should number the FP stack registers
337 for the x86 architecture. If the version of SDB on x86/svr4 were
338 a bit less brain dead with respect to floating-point then we would
339 have a precedent to follow with respect to DWARF register numbers
340 for x86 FP registers, but the SDB on x86/svr4 is so completely
341 broken with respect to FP registers that it is hardly worth thinking
342 of it as something to strive for compatibility with.
343 The version of x86/svr4 SDB I have at the moment does (partially)
344 seem to believe that DWARF register number 11 is associated with
345 the x86 register %st(0), but that's about all. Higher DWARF
346 register numbers don't seem to be associated with anything in
347 particular, and even for DWARF regno 11, SDB only seems to under-
348 stand that it should say that a variable lives in %st(0) (when
349 asked via an `=' command) if we said it was in DWARF regno 11,
350 but SDB still prints garbage when asked for the value of the
351 variable in question (via a `/' command).
352 (Also note that the labels SDB prints for various FP stack regs
353 when doing an `x' command are all wrong.)
354 Note that these problems generally don't affect the native SVR4
355 C compiler because it doesn't allow the use of -O with -g and
356 because when it is *not* optimizing, it allocates a memory
357 location for each floating-point variable, and the memory
358 location is what gets described in the DWARF AT_location
359 attribute for the variable in question.
360 Regardless of the severe mental illness of the x86/svr4 SDB, we
361 do something sensible here and we use the following DWARF
362 register numbers. Note that these are all stack-top-relative
363 numbers.
