68 /* Let (offset,szB) describe a reference to the guest state section
71 This function returns the corresponding guest state reference to be
72 used for the origin tag (which of course will be in the second
73 shadow area), or -1 if this piece of guest state is not to be
76 Since origin tags are 32-bits long, we expect any returned value
77 (except -1) to be a multiple of 4, between 0 and
78 sizeof(guest-state)-4 inclusive.
80 This is inherently (guest-)architecture specific. For x86 and
81 amd64 we do some somewhat tricky things to give %AH .. %DH their
82 own tags. On ppc32/64 we do some marginally tricky things to give
83 all 16 %CR components their own tags.
85 This function only deals with references to the guest state whose
86 offsets are known at translation time (that is, references arising
87 from Put and Get). References whose offset is not known until run
88 time (that is, arise from PutI and GetI) are handled by
89 MC_(get_otrack_reg_array_equiv_int_type) below.
91 Note that since some guest state arrays (eg, the x86 FP reg stack)
92 are accessed both as arrays (eg, x87 insns) and directly (eg, MMX
93 insns), the two functions must be consistent for those sections of
94 guest state -- that is, they must both say the area is shadowed, or
97 This function is dependent on the host's endianness, hence we
98 assert that the use case is supported.
