symcompact
symcompact(1) General Commands Manual symcompact(1)
NAME
symcompact - string compaction for object files
SYNOPSIS
symcompact [ object_name ... ]
DESCRIPTION
symcompact reduces the symbol table size of an executable file. This is done by removing unnecessary overlay transfer vectors (text sym-
bols beginning with a tilde). In a nonoverlaid program there is no need for both the underscore (_foo) and tilde (~foo) text symbol and
only the underscore form is kept. For overlaid programs if the symbol is in the base segment the tilde form is not needed and again only
the underscore form is preserved. Running symcompact typically reduces the kernel symbol table size by 250 or so symbols.
It is possible to run both symcompact and strcompact to achieve an even higher degree of symbol and string table compaction. The normal
sequence is to run symcompact first followed by strcompact. If symcompact runs out of memory it will be necessary to reverse the order and
run symcompact a second time - see the BUGS note below.
The user must have write permission to the object/executable file.
symcompact writes to stderr the count of symbols removed from the symbol table.
symcompact exits 0 if successful, and >0 if an error occurred.
SEE ALSO
symcompact(1), symorder(1)
BUGS
This program can partially negate the benefits of strcompact because multiple references to identical strings cause additional strings to
be placed in the string table. Running strcompact again after running this program fixes this problem.
The register local symbol type is removed from the executable/object file. Since the debugger really doesn't know how to deal with those
symbols this is not much of a loss and saves quite a bit of space both in the symbol table and the string table.
symcompact should not be run on .o files that will be passed to the linker. The linker will need the tilde form of the symbol if an over-
laid executable is being created.
