A notes file, which is + generated by the compiler, and a data file, which is generated by + the program under test. Both files use a similar structure. We do + not attempt to make these files backwards compatible with previous + versions, as you only need coverage information when developing a + program. We do hold version information, so that mismatches can be + detected, and we use a format that allows tools to skip information + they do not understand or are not interested in. + + Numbers are recorded in the 32 bit unsigned binary form of the + endianness of the machine generating the file. 64 bit numbers are + stored as two 32 bit numbers, the low part first. Strings are + padded with 1 to 4 NUL bytes, to bring the length up to a multiple + of 4. The number of 4 bytes is stored, followed by the padded + string. Zero length and NULL strings are simply stored as a length + of zero (they have no trailing NUL or padding). + + int32: byte3 byte2 byte1 byte0 | byte0 byte1 byte2 byte3 + int64: int32:low int32:high + string: int32:0 | int32:length char* char:0 padding + padding: | char:0 | char:0 char:0 | char:0 char:0 char:0 + item: int32 | int64 | string + + The basic format of the files is + + file : int32:magic int32:version int32:stamp record* + + The magic ident is different for the notes and the data files. The + magic ident is used to determine the endianness of the file, when + reading. The version is the same for both files and is derived + from gcc's version number. The stamp value is used to synchronize + note and data files and to synchronize merging within a data + file. It need not be an absolute time stamp, merely a ticker that + increments fast enough and cycles slow enough to distinguish + different compile/run/compile cycles. + + Although the ident and version are formally 32 bit numbers, they + are derived from 4 character ASCII strings. The version number + consists of a two character major version number + (first digit starts from 'A' letter to not to clash with the older + numbering scheme), the single character minor version number, + and a single character indicating the status of the release. + That will be 'e' experimental, 'p' prerelease and 'r' for release. + Because, by good fortune, these are in alphabetical order, string + collating can be used to compare version strings. Be aware that + the 'e' designation will (naturally) be unstable and might be + incompatible with itself. For gcc 17.0 experimental, it would be + 'B70e' (0x42373065). As we currently do not release more than 5 minor + releases, the single character should be always fine. Major number + is currently changed roughly every year, which gives us space + for next 250 years (maximum allowed number would be 259.9). + + A record has a tag, length and variable amount of data. + + record: header data + header: int32:tag int32:length + data: item* + + Records are not nested, but there is a record hierarchy. Tag + numbers reflect this hierarchy. Tags are unique across note and + data files. Some record types have a varying amount of data. The + LENGTH is the number of 4bytes that follow and is usually used to + determine how much data. The tag value is split into 4 8-bit + fields, one for each of four possible levels. The most significant + is allocated first. Unused levels are zero. Active levels are + odd-valued, so that the LSB of the level is one. A sub-level + incorporates the values of its superlevels. This formatting allows + you to determine the tag hierarchy, without understanding the tags + themselves, and is similar to the standard section numbering used + in technical documents.
