1635 The SVR4 reference port C compiler uses the following register numbers
1636 in its Dwarf output code:
1637 0 for %eax (gcc regno = 0)
1638 1 for %ecx (gcc regno = 2)
1639 2 for %edx (gcc regno = 1)
1640 3 for %ebx (gcc regno = 3)
1641 4 for %esp (gcc regno = 7)
1642 5 for %ebp (gcc regno = 6)
1643 6 for %esi (gcc regno = 4)
1644 7 for %edi (gcc regno = 5)
1645 The following three DWARF register numbers are never generated by
1646 the SVR4 C compiler or by the GNU compilers, but SDB on x86/svr4
1647 believes these numbers have these meanings.
1648 8 for %eip (no gcc equivalent)
1649 9 for %eflags (gcc regno = 17)
1650 10 for %trapno (no gcc equivalent)
1651 It is not at all clear how we should number the FP stack registers
1652 for the x86 architecture. If the version of SDB on x86/svr4 were
1653 a bit less brain dead with respect to floating-point then we would
1654 have a precedent to follow with respect to DWARF register numbers
1655 for x86 FP registers, but the SDB on x86/svr4 is so completely
1656 broken with respect to FP registers that it is hardly worth thinking
1657 of it as something to strive for compatibility with.
1658 The version of x86/svr4 SDB I have at the moment does (partially)
1659 seem to believe that DWARF register number 11 is associated with
1660 the x86 register %st(0), but that's about all. Higher DWARF
1661 register numbers don't seem to be associated with anything in
1662 particular, and even for DWARF regno 11, SDB only seems to under-
1663 stand that it should say that a variable lives in %st(0) (when
1664 asked via an `=' command) if we said it was in DWARF regno 11,
1665 but SDB still prints garbage when asked for the value of the
1666 variable in question (via a `/' command).
1667 (Also note that the labels SDB prints for various FP stack regs
1668 when doing an `x' command are all wrong.)
1669 Note that these problems generally don't affect the native SVR4
1670 C compiler because it doesn't allow the use of -O with -g and
1671 because when it is *not* optimizing, it allocates a memory
1672 location for each floating-point variable, and the memory
1673 location is what gets described in the DWARF AT_location
1674 attribute for the variable in question.
1675 Regardless of the severe mental illness of the x86/svr4 SDB, we
1676 do something sensible here and we use the following DWARF
1677 register numbers. Note that these are all stack-top-relative
1679 11 for %st(0) (gcc regno = 8)
1680 12 for %st(1) (gcc regno = 9)
1681 13 for %st(2) (gcc regno = 10)
1682 14 for %st(3) (gcc regno = 11)
1683 15 for %st(4) (gcc regno = 12)
1684 16 for %st(5) (gcc regno = 13)
1685 17 for %st(6) (gcc regno = 14)

29983 version is skipped - this incurs a misprediction cost (because the
29984 vectorized version is expected to be the fall-through). So we subtract
29985 the latency of a mispredicted branch from the costs that are incured
29986 when the vectorized version is executed.
29988 TODO: The values in individual target tables have to be tuned or new
29989 fields may be needed. For eg. on K8, the default branch path is the
29990 not-taken path. If the taken path is predicted correctly, the minimum
29991 penalty of going down the taken-path is 1 cycle. If the taken-path is
29992 not predicted correctly, then the minimum penalty is 10 cycles. */
