strcompact(1)  —  Unix Programmer’s Manual

NAME

strcompact − string compaction for object files

SYNOPSIS

strcompact [ object_name ... ]

DESCRIPTION

strcompact scans the symbol and string tables of an object file looking for multiple references in the symbol table to the same string.  The string offset of symbol table entries is updated to preserve only one copy of the string. 

strcompact cut the size of the kernel string table by about 25%. 

The user must have write permission to the object/executable file. 

strcompact writes to stderr the number of shared strings found. 

strcompact exits 0 if successful, and >0 if an error occurred. 

SEE ALSO

sort(1), symcompact(1), symorder(1), uniq(1)

BUGS

Execution speed leaves much to be desired - on a 11/73 it takes about 4 minutes to process the string table of the kernel.  Fortunately this is only done once when the kernel is created. 

Although strcompact may be run on .o files as well as executables but this is probably not worth the trouble since the linker will not create shared strings in the final executable.
