136 * The mne structure is a linked list of the assembler
137 * mnemonics and directives. The list of mnemonics and
138 * directives contained in the device dependent file
139 * xxxpst.c are hashed and linked into NHASH lists in
140 * module assym.c by syminit(). The structure contains
141 * the mnemonic/directive name, a subtype which directs
142 * the evaluation of this mnemonic/directive, a flag which
143 * is used to detect the end of the mnemonic/directive
144 * list in xxxpst.c, and a value which is normally
145 * associated with the assembler mnemonic base instruction
150 * struct mne *m_mp; Hash link
151 * char m_id[NCPS]; Mnemonic
152 * char m_type; Mnemonic subtype
153 * char m_flag; Mnemonic flags
154 * Addr_T m_valu; Value
157 struct mne *mnehash[NHASH];
160 * The sym structure is a linked list of symbols defined
161 * in the assembler source files. The first symbol is "."
162 * defined here. The entry 'struct tsym *s_tsym'
163 * links any temporary symbols following this symbol and
164 * preceeding the next normal symbol. The structure also
165 * contains the symbol's name, type (USER or NEW), flag
166 * (global, assigned, and multiply defined), a pointer
167 * to the area structure defining where the symbol is
168 * located, a reference number assigned by outgsd() in
169 * asout.c, and the symbols address relative to the base
170 * address of the area where the symbol is located.
174 * struct sym *s_sp; Hash link
175 * struct tsym *s_tsym; Temporary symbol link
176 * char s_id[NCPS]; Symbol
177 * char s_type; Symbol subtype
178 * char s_flag; Symbol flags
179 * struct area *s_area; Area line, 0 if absolute
180 * int s_ref; Ref. number
181 * Addr_T s_addr; Address
185 { NULL, NULL, ".", S_USER, S_END, NULL, 0, }
188 struct sym *symp; /* pointer to a symbol structure
190 struct sym *symhash[NHASH]; /* array of pointers to NHASH
191 * linked symbol lists
195 * The area structure contains the parameter values for a
196 * specific program or data section. The area structure
197 * is a linked list of areas. The initial default area
198 * is "_CODE" defined here, the next area structure
199 * will be linked to this structure through the structure
200 * element 'struct area *a_ep'. The structure contains the
201 * area name, area reference number ("_CODE" is 0) determined
202 * by the order of .area directives, area size determined
203 * from the total code and/or data in an area, area fuzz is
204 * an variable used to track pass to pass changes in the
205 * area size caused by variable length instruction formats,
206 * and area flags which specify the area's relocation type.
210 * struct area *a_ap; Area link
211 * char a_id[NCPS]; Area Name
212 * int a_ref; Reference number
213 * Addr_T a_size; Area size
214 * Addr_T a_fuzz; Area fuzz
215 * int a_flag; Area flags
