40 | /* Coverage information is held in two files. A notes file, which is | |
|
41 | generated by the compiler, and a data file, which is generated | |
|
42 | by the program under test. Both files use a similar structure. We | |
|
43 | do not attempt to make these files backwards compatible with | |
|
44 | previous versions, as you only need coverage information when | |
|
45 | developing a program. We do hold version information, so that | |
|
46 | mismatches can be detected, and we use a format that allows tools | |
|
47 | to skip information they do not understand or are not interested | |
|
48 | in. | |
|
49 | ||
|
50 | Numbers are recorded in the 32 bit unsigned binary form of the | |
|
51 | endianness of the machine generating the file. 64 bit numbers are | |
|
52 | stored as two 32 bit numbers, the low part first. Strings are | |
|
53 | padded with 1 to 4 NUL bytes, to bring the length up to a multiple | |
|
54 | of 4. The number of 4 bytes is stored, followed by the padded | |
|
55 | string. Zero length and NULL strings are simply stored as | |
|
56 | a length of zero (they have no trailing NUL or padding). | |
|

|
62 | item: int32 | int64 | string | |
|
63 | ||
|
64 | The basic format of the files is | |
|
65 | ||
|
66 | file : int32:magic int32:version int32:stamp record* | |
|
67 | ||
|
68 | The magic ident is different for the notes and the data files. The | |
|
69 | magic ident is used to determine the endianness of the file, when | |
|
70 | reading. The version is the same for both files and is derived | |
|
71 | from gcc's version number. The stamp value is used to synchronize | |
|
72 | note and data files and to synchronize merging within a data | |
|
73 | file. It need not be an absolute time stamp, merely a ticker that | |
|
74 | increments fast enough and cycles slow enough to distinguish | |
|
75 | different compile/run/compile cycles. | |
|
76 | ||
|
77 | Although the ident and version are formally 32 bit numbers, they | |
|
78 | are derived from 4 character ASCII strings. The version number | |
|
79 | consists of the single character major version number, a two | |
|
80 | character minor version number (leading zero for versions less than | |
|
81 | 10), and a single character indicating the status of the release. | |
|
82 | That will be 'e' experimental, 'p' prerelease and 'r' for release. | |
|
83 | Because, by good fortune, these are in alphabetical order, string | |
|
84 | collating can be used to compare version strings. Be aware that | |
|
85 | the 'e' designation will (naturally) be unstable and might be | |
|
86 | incompatible with itself. For gcc 3.4 experimental, it would be | |
|
87 | '304e' (0x33303465). When the major version reaches 10, the | |
|
88 | letters A-Z will be used. Assuming minor increments releases every | |
|
89 | 6 months, we have to make a major increment every 50 years. | |
|
90 | Assuming major increments releases every 5 years, we're ok for the | |
|
91 | next 155 years -- good enough for me. | |
|
92 | ||
|
93 | A record has a tag, length and variable amount of data. | |
|
94 | ||
|
95 | record: header data | |
|
96 | header: int32:tag int32:length | |
|
97 | data: item* | |
|
98 | ||
|
99 | Records are not nested, but there is a record hierarchy. Tag | |
|
100 | numbers reflect this hierarchy. Tags are unique across note and | |
|
101 | data files. Some record types have a varying amount of data. The | |
|
102 | LENGTH is the number of 4bytes that follow and is usually used to | |
|
103 | determine how much data. The tag value is split into 4 8-bit | |
|
104 | fields, one for each of four possible levels. The most significant | |
|
105 | is allocated first. Unused levels are zero. Active levels are | |
|
106 | odd-valued, so that the LSB of the level is one. A sub-level | |
|
107 | incorporates the values of its superlevels. This formatting allows | |
|
108 | you to determine the tag hierarchy, without understanding the tags | |
|
109 | themselves, and is similar to the standard section numbering used | |
|
110 | in technical documents. Level values [1..3f] are used for common | |
|
111 | tags, values [41..9f] for the notes file and [a1..ff] for the data | |
|
112 | file. | |
|
113 | ||
|
114 | The basic block graph file contains the following records | |
|
115 | note: unit function-graph* | |
|
116 | unit: header int32:checksum string:source | |
|
117 | function-graph: announce_function basic_blocks {arcs | lines}* | |
|
118 | announce_function: header int32:ident int32:checksum | |
|
119 | string:name string:source int32:lineno | |
|
120 | basic_block: header int32:flags* | |
|
121 | arcs: header int32:block_no arc* | |
|
122 | arc: int32:dest_block int32:flags | |
|
123 | lines: header int32:block_no line* | |
|
124 | int32:0 string:NULL | |
|
125 | line: int32:line_no | int32:0 string:filename | |
|
126 | ||
|
127 | The BASIC_BLOCK record holds per-bb flags. The number of blocks | |
|
128 | can be inferred from its data length. There is one ARCS record per | |
|
129 | basic block. The number of arcs from a bb is implicit from the | |
|
130 | data length. It enumerates the destination bb and per-arc flags. | |
|
131 | There is one LINES record per basic block, it enumerates the source | |
|
132 | lines which belong to that basic block. Source file names are | |
|
133 | introduced by a line number of 0, following lines are from the new | |
|
134 | source file. The initial source file for the function is NULL, but | |
|
135 | the current source file should be remembered from one LINES record | |
|
136 | to the next. The end of a block is indicated by an empty filename | |
|
137 | - this does not reset the current source file. Note there is no | |
|
138 | ordering of the ARCS and LINES records: they may be in any order, | |
|
139 | interleaved in any manner. The current filename follows the order | |
|
140 | the LINES records are stored in the file, *not* the ordering of the | |
|
141 | blocks they are for. | |
|
142 | ||
|
143 | The data file contains the following records. | |
|
144 | data: {unit function-data* summary:object summary:program*}* | |
|
145 | unit: header int32:checksum | |
|
146 | function-data: announce_function arc_counts | |
|
147 | announce_function: header int32:ident int32:checksum | |
|
148 | arc_counts: header int64:count* | |
|
149 | summary: int32:checksum {count-summary}GCOV_COUNTERS | |
|
150 | count-summary: int32:num int32:runs int64:sum | |
|
151 | int64:max int64:sum_max | |
|
152 | ||
|
153 | The ANNOUNCE_FUNCTION record is the same as that in the note file, | |
|
154 | but without the source location. The ARC_COUNTS gives the counter | |
|
155 | values for those arcs that are instrumented. The SUMMARY records | |
|
156 | give information about the whole object file and about the whole | |
|
157 | program. The checksum is used for whole program summaries, and | |
|
158 | disambiguates different programs which include the same | |
|
159 | instrumented object file. There may be several program summaries, | |
|
160 | each with a unique checksum. The object summary's checksum is zero. | |
|
161 | Note that the data file might contain information from several runs | |
|
162 | concatenated, or the data might be merged. | |
|
163 | ||
|
164 | This file is included by both the compiler, gcov tools and the | |
|
165 | runtime support library libgcov. IN_LIBGCOV and IN_GCOV are used to | |
|
166 | distinguish which case is which. If IN_LIBGCOV is nonzero, | |
|
167 | libgcov is being built. If IN_GCOV is nonzero, the gcov tools are | |
|
168 | being built. Otherwise the compiler is being built. IN_GCOV may be | |
|
169 | positive or negative. If positive, we are compiling a tool that | |
|
170 | requires additional functions (see the code for knowledge of what | |
|
171 | those functions are). */ | |
