-/* Define the register numbers to be used in Dwarf debugging information.
- The SVR4 reference port C compiler uses the following register numbers
- in its Dwarf output code:
- 0 for %eax (gnu regno = 0)
- 1 for %ecx (gnu regno = 2)
- 2 for %edx (gnu regno = 1)
- 3 for %ebx (gnu regno = 3)
- 4 for %esp (gnu regno = 7)
- 5 for %ebp (gnu regno = 6)
- 6 for %esi (gnu regno = 4)
- 7 for %edi (gnu regno = 5)
- The following three DWARF register numbers are never generated by
- the SVR4 C compiler or by the GNU compilers, but SDB on x86/svr4
- believes these numbers have these meanings.
- 8 for %eip (no gnu equivalent)
- 9 for %eflags (no gnu equivalent)
- 10 for %trapno (no gnu equivalent)
- It is not at all clear how we should number the FP stack registers
- for the x86 architecture. If the version of SDB on x86/svr4 were
- a bit less brain dead with respect to floating-point then we would
- have a precedent to follow with respect to DWARF register numbers
- for x86 FP registers, but the SDB on x86/svr4 is so completely
- broken with respect to FP registers that it is hardly worth thinking
- of it as something to strive for compatibility with.
- The version of x86/svr4 SDB I have at the moment does (partially)
- seem to believe that DWARF register number 11 is associated with
- the x86 register %st(0), but that's about all. Higher DWARF
- register numbers don't seem to be associated with anything in
- particular, and even for DWARF regno 11, SDB only seems to under-
- stand that it should say that a variable lives in %st(0) (when
- asked via an `=' command) if we said it was in DWARF regno 11,
- but SDB still prints garbage when asked for the value of the
- variable in question (via a `/' command).
- (Also note that the labels SDB prints for various FP stack regs
- when doing an `x' command are all wrong.)
- Note that these problems generally don't affect the native SVR4
- C compiler because it doesn't allow the use of -O with -g and
- because when it is *not* optimizing, it allocates a memory
- location for each floating-point variable, and the memory
- location is what gets described in the DWARF AT_location
- attribute for the variable in question.
- Regardless of the severe mental illness of the x86/svr4 SDB, we
- do something sensible here and we use the following DWARF
- register numbers. Note that these are all stack-top-relative
- numbers.
- 11 for %st(0) (gnu regno = 8)
- 12 for %st(1) (gnu regno = 9)
- 13 for %st(2) (gnu regno = 10)
- 14 for %st(3) (gnu regno = 11)
- 15 for %st(4) (gnu regno = 12)
- 16 for %st(5) (gnu regno = 13)
- 17 for %st(6) (gnu regno = 14)
- 18 for %st(7) (gnu regno = 15)
