The format requires the + field to be NUL-padded, but not necessarily NUL-terminated, so + the longest section names permitted are a full eight characters. + + The Microsoft PE variants of the Coff object file format add + an extension to support the use of long section names. This + extension is defined in section 4 of the Microsoft PE/COFF + specification (rev 8.1). If a section name is too long to fit + into the section header's @code{s_name} field, it is instead + placed into the string table, and the @code{s_name} field is + filled with a slash ("/") followed by the ASCII decimal + representation of the offset of the full name relative to the + string table base. + + Note that this implies that the extension can only be used in object + files, as executables do not contain a string table. The standard + specifies that long section names from objects emitted into executable + images are to be truncated. + + However, as a GNU extension, BFD can generate executable images + that contain a string table and long section names. This + would appear to be technically valid, as the standard only says + that Coff debugging information is deprecated, not forbidden, + and in practice it works, although some tools that parse PE files + expecting the MS standard format may become confused; @file{PEview} is + one known example. + + The functionality is supported in BFD by code implemented under + the control of the macro @code{COFF_LONG_SECTION_NAMES}.

The flag controls the generation of long section names + in output BFDs at runtime; if it is false, as it will be by default + when generating an executable image, long section names are truncated; + if true, the long section names extension is employed. The hook + points to a function that allows the value of the flag to be altered + at runtime, on formats that support long section names at all; on + other formats it points to a stub that returns an error indication. + + If @code{COFF_LONG_SECTION_NAMES} is simply defined (blank), or is + defined to the value "1", then long section names are enabled by + default; if it is defined to the value zero, they are disabled by + default (but still accepted in input BFDs).
