NAME

       nmcoll - find name collisions in object files (2BSD)

SYNOPSIS

       nmcoll file ...

DESCRIPTION

       Nmcoll scans a set of object files as produced by the assembler (typically ending with .o) and produces a listing of suspicious name dupli-
       cations.  Nmcoll is useful when porting programs that were developed with compilers that support flex (long) names to  2.11BSD  which  only
       supports seven significant characters in external names.

NOTES

       Nmcoll is a carryover from the era before longer symbol names were supported in object files.

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 cre-
       ate shared strings in the final executable.
