1566 The SVR4 reference port C compiler uses the following register numbers
1567 in its Dwarf output code:
1568 0 for %eax (gcc regno = 0)
1569 1 for %ecx (gcc regno = 2)
1570 2 for %edx (gcc regno = 1)
1571 3 for %ebx (gcc regno = 3)
1572 4 for %esp (gcc regno = 7)
1573 5 for %ebp (gcc regno = 6)
1574 6 for %esi (gcc regno = 4)
1575 7 for %edi (gcc regno = 5)
1576 The following three DWARF register numbers are never generated by
1577 the SVR4 C compiler or by the GNU compilers, but SDB on x86/svr4
1578 believes these numbers have these meanings.
1579 8 for %eip (no gcc equivalent)
1580 9 for %eflags (gcc regno = 17)
1581 10 for %trapno (no gcc equivalent)
1582 It is not at all clear how we should number the FP stack registers
1583 for the x86 architecture. If the version of SDB on x86/svr4 were
1584 a bit less brain dead with respect to floating-point then we would
1585 have a precedent to follow with respect to DWARF register numbers
1586 for x86 FP registers, but the SDB on x86/svr4 is so completely
1587 broken with respect to FP registers that it is hardly worth thinking
1588 of it as something to strive for compatibility with.
1589 The version of x86/svr4 SDB I have at the moment does (partially)
1590 seem to believe that DWARF register number 11 is associated with
1591 the x86 register %st(0), but that's about all. Higher DWARF
1592 register numbers don't seem to be associated with anything in
1593 particular, and even for DWARF regno 11, SDB only seems to under-
1594 stand that it should say that a variable lives in %st(0) (when
1595 asked via an `=' command) if we said it was in DWARF regno 11,
1596 but SDB still prints garbage when asked for the value of the
1597 variable in question (via a `/' command).
1598 (Also note that the labels SDB prints for various FP stack regs
1599 when doing an `x' command are all wrong.)
1600 Note that these problems generally don't affect the native SVR4
1601 C compiler because it doesn't allow the use of -O with -g and
1602 because when it is *not* optimizing, it allocates a memory
1603 location for each floating-point variable, and the memory
1604 location is what gets described in the DWARF AT_location
1605 attribute for the variable in question.
1606 Regardless of the severe mental illness of the x86/svr4 SDB, we
1607 do something sensible here and we use the following DWARF
1608 register numbers. Note that these are all stack-top-relative
1610 11 for %st(0) (gcc regno = 8)
1611 12 for %st(1) (gcc regno = 9)
1612 13 for %st(2) (gcc regno = 10)
1613 14 for %st(3) (gcc regno = 11)
1614 15 for %st(4) (gcc regno = 12)
1615 16 for %st(5) (gcc regno = 13)
1616 17 for %st(6) (gcc regno = 14)
