|
---|
60 | The SVR4 reference port C compiler uses the following register numbers
|
---|
61 | in its Dwarf output code:
|
---|
62 | 0 for %eax (gnu regno = 0)
|
---|
63 | 1 for %ecx (gnu regno = 2)
|
---|
64 | 2 for %edx (gnu regno = 1)
|
---|
65 | 3 for %ebx (gnu regno = 3)
|
---|
66 | 4 for %esp (gnu regno = 7)
|
---|
67 | 5 for %ebp (gnu regno = 6)
|
---|
68 | 6 for %esi (gnu regno = 4)
|
---|
69 | 7 for %edi (gnu regno = 5)
|
---|
70 | The following three DWARF register numbers are never generated by
|
---|
71 | the SVR4 C compiler or by the GNU compilers, but SDB on x86/svr4
|
---|
72 | believes these numbers have these meanings.
|
---|
73 | 8 for %eip (no gnu equivalent)
|
---|
74 | 9 for %eflags (no gnu equivalent)
|
---|
75 | 10 for %trapno (no gnu equivalent)
|
---|
76 | It is not at all clear how we should number the FP stack registers
|
---|
77 | for the x86 architecture. If the version of SDB on x86/svr4 were
|
---|
78 | a bit less brain dead with respect to floating-point then we would
|
---|
79 | have a precedent to follow with respect to DWARF register numbers
|
---|
80 | for x86 FP registers, but the SDB on x86/svr4 is so completely
|
---|
81 | broken with respect to FP registers that it is hardly worth thinking
|
---|
82 | of it as something to strive for compatibility with.
|
---|
83 | The version of x86/svr4 SDB I have at the moment does (partially)
|
---|
84 | seem to believe that DWARF register number 11 is associated with
|
---|
85 | the x86 register %st(0), but that's about all. Higher DWARF
|
---|
86 | register numbers don't seem to be associated with anything in
|
---|
87 | particular, and even for DWARF regno 11, SDB only seems to under-
|
---|
88 | stand that it should say that a variable lives in %st(0) (when
|
---|
89 | asked via an `=' command) if we said it was in DWARF regno 11,
|
---|
90 | but SDB still prints garbage when asked for the value of the
|
---|
91 | variable in question (via a `/' command).
|
---|
92 | (Also note that the labels SDB prints for various FP stack regs
|
---|
93 | when doing an `x' command are all wrong.)
|
---|
94 | Note that these problems generally don't affect the native SVR4
|
---|
95 | C compiler because it doesn't allow the use of -O with -g and
|
---|
96 | because when it is *not* optimizing, it allocates a memory
|
---|
97 | location for each floating-point variable, and the memory
|
---|
98 | location is what gets described in the DWARF AT_location
|
---|
99 | attribute for the variable in question.
|
---|
100 | Regardless of the severe mental illness of the x86/svr4 SDB, we
|
---|
101 | do something sensible here and we use the following DWARF
|
---|
102 | register numbers. Note that these are all stack-top-relative
|
---|
103 | numbers.
|
---|
104 | 11 for %st(0) (gnu regno = 8)
|
---|
105 | 12 for %st(1) (gnu regno = 9)
|
---|
106 | 13 for %st(2) (gnu regno = 10)
|
---|
107 | 14 for %st(3) (gnu regno = 11)
|
---|
108 | 15 for %st(4) (gnu regno = 12)
|
---|
109 | 16 for %st(5) (gnu regno = 13)
|
---|
110 | 17 for %st(6) (gnu regno = 14)
|
---|
111 | 18 for %st(7) (gnu regno = 15)
