/* 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)
