83 | are represented by `struct block' objects. | |
84 | All of these objects are pointed to by the blockvector. | |
85 | ||
86 | Each block represents one name scope. | |
87 | Each lexical context has its own block. | |
88 | ||
89 | The blockvector begins with some special blocks. | |
90 | The GLOBAL_BLOCK contains all the symbols defined in this compilation | |

92 | The STATIC_BLOCK contains all the symbols whose scope is the | |
93 | entire compilation excluding other separate compilations. | |
94 | Blocks starting with the FIRST_LOCAL_BLOCK are not special. | |
95 | ||
96 | Each block records a range of core addresses for the code that | |
97 | is in the scope of the block. The STATIC_BLOCK and GLOBAL_BLOCK | |
98 | give, for the range of code, the entire range of code produced | |
99 | by the compilation that the symbol segment belongs to. | |
100 | ||
101 | The blocks appear in the blockvector | |
102 | in order of increasing starting-address, | |
103 | and, within that, in order of decreasing ending-address. | |
104 | ||
105 | This implies that within the body of one function | |
