39: DESCRIPTION
40: Each port of BFD to a different machine requires the creation
41: of a target back end. All the back end provides to the root
42: part of BFD is a structure containing pointers to functions
43: which perform certain low level operations on files. BFD
44: translates the applications's requests through a pointer into
45: calls to the back end routines.
46:
47: When a file is opened with <<bfd_openr>>, its format and
48: target are unknown. BFD uses various mechanisms to determine
49: how to interpret the file. The operations performed are:
50:
51: o Create a BFD by calling the internal routine
52: <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the
53: target string supplied to <<bfd_openr>> and the new BFD pointer.
54:
55: o If a null target string was provided to <<bfd_find_target>>,
56: look up the environment variable <<GNUTARGET>> and use
57: that as the target string.
58:
59: o If the target string is still <<NULL>>, or the target string is
60: <<default>>, then use the first item in the target vector
61: as the target type, and set <<target_defaulted>> in the BFD to
62: cause <<bfd_check_format>> to loop through all the targets.
63: @xref{bfd_target}. @xref{Formats}.
64:
65: o Otherwise, inspect the elements in the target vector
66: one by one, until a match on target name is found. When found,
67: use it.
68:
69: o Otherwise return the error <<bfd_error_invalid_target>> to
70: <<bfd_openr>>.
71:
72: o <<bfd_openr>> attempts to open the file using
73: <<bfd_open_file>>, and returns the BFD.
74:
75: Once the BFD has been opened and the target selected, the file
76: format may be determined. This is done by calling
77: <<bfd_check_format>> on the BFD with a suggested format.
78: If <<target_defaulted>> has been set, each possible target
79: type is tried to see if it recognizes the specified format.
80: <<bfd_check_format>> returns <<TRUE>> when the caller guesses right.

94: DESCRIPTION
95: This structure contains everything that BFD knows about a
96: target. It includes things like its byte order, name, and which
97: routines to call to do various operations.
98:
99: Every BFD points to a target structure with its <<xvec>>
100: member.
101:
102: The macros below are used to dispatch to functions through the
103: <<bfd_target>> vector. They are used in a number of macros further
104: down in @file{bfd.h}, and are also used when calling various
105: routines by hand inside the BFD implementation. The @var{arglist}
106: argument must be parenthesized; it contains all the arguments
107: to the called function.
108:
109: They make the documentation (more) unpleasant to read, so if
110: someone wants to fix this and not break the above, please do.
111:
112: .#define BFD_SEND(bfd, message, arglist) \
113: . ((*((bfd)->xvec->message)) arglist)
114: .
115: .#ifdef DEBUG_BFD_SEND
116: .#undef BFD_SEND
117: .#define BFD_SEND(bfd, message, arglist) \
118: . (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
119: . ((*((bfd)->xvec->message)) arglist) : \
120: . (bfd_assert (__FILE__,__LINE__), NULL))
121: .#endif
122:
123: For operations which index on the BFD format:
124:
125: .#define BFD_SEND_FMT(bfd, message, arglist) \
126: . (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
127: .

129: .#undef BFD_SEND_FMT
130: .#define BFD_SEND_FMT(bfd, message, arglist) \
131: . (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
132: . (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
133: . (bfd_assert (__FILE__,__LINE__), NULL))
134: .#endif
135: .
136: This is the structure which defines the type of BFD this is. The
137: <<xvec>> member of the struct <<bfd>> itself points here. Each
138: module that implements access to a different target under BFD,
139: defines one of these.
140:
141: FIXME, these names should be rationalised with the names of
142: the entry points which call them. Too bad we can't have one
143: macro to define them both!

1703: that is null or not defined, then choose the first entry in the
1704: target list. Passing in the string "default" or setting the

1706: the target list to be returned, and "target_defaulted" will be
1707: set in the BFD if @var{abfd} isn't <<NULL>>. This causes
1708: <<bfd_check_format>> to loop over all the targets to find the
1709: one that matches the file being read.
1710: If @var{is_bigendian} is not <<NULL>>, then set this value to target's
1711: endian mode. True for big-endian, FALSE for little-endian or for
1712: invalid target.
1713: If @var{underscoring} is not <<NULL>>, then set this value to target's
1714: underscoring mode. Zero for none-underscoring, -1 for invalid target,
1715: else the value of target vector's symbol underscoring.
1716: If @var{def_target_arch} is not <<NULL>>, then set it to the architecture
1717: string specified by the target_name.
