Bug ID: 94928
Summary: Doc comments in gcov-io.h do not show cwd and unexec
blocks in the Notes file format
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: myron.walker at gmail dot com
CC: marxin at gcc dot gnu.org
Target Milestone: ---
The documentation of the notes file format below do not show the cwd or
unexec_blocks data items.
note: unit function-graph*
unit: header int32:checksum string:source
function-graph: announce_function basic_blocks {arcs | lines}*
announce_function: header int32:ident
int32:lineno_checksum int32:cfg_checksum
string:name string:source int32:start_lineno int32:start_column
int32:end_lineno
basic_block: header int32:flags*
arcs: header int32:block_no arc*
arc: int32:dest_block int32:flags
lines: header int32:block_no line*
int32:0 string:NULL
line: int32:line_no | int32:0 string:filename
When you look at the gcov.c file, you can see that at the beginning of the
notes file right after the stamp, there is an item for cwd and unexec blocks.
bbg_stamp = gcov_read_unsigned();
bbg_cwd = xstrdup(gcov_read_string()); <<<<< Not documented
bbg_supports_has_unexecuted_blocks = gcov_read_unsigned(); <<<<<< Not
documented
There also is a missing int32:artificial that should be between the function
name and function source file.
function_name = xstrdup(gcov_read_string());
unsigned artificial = gcov_read_unsigned(); <<<< Not documented
unsigned src_idx = find_source(gcov_read_string());
