* ptlink - parameterized type instantiation program
*
* Usage: ptlink ptrepository /usr/tmp/CC.12345 /usr/bin/CC
* /usr/tmp/CC.12345/ptincl /usr/tmp/CC.12345/ptin
* /usr/tmp/CC.12345/ptout defmap /usr/tmp/CC.12345.ptccopt
* /usr/tmp/CC.12345/ptrlistx /lib/cpp
*
* where ptrepository is the repository directory,
* /usr/tmp/CC.12345 is a temporary directory,
* /usr/bin/CC is the name of the CC command,
* /usr/tmp/CC.12345/ptincl is a file containing all of the -I options,
* /usr/tmp/CC.12345/ptin is a file that contains all of the .o and .a files
* that were found on the original link line,
* /usr/tmp/CC.12345/ptout is a file that will contain a list of all of the
* extra .o files in the repository directory that must be linked in,
* defmap is the name
* /usr/tmp/CC.12345/ptccopt is a file that contains all of the extra CC
* options that were on the original CC line,
* /usr/tmp/CC.12345/ptrlistx is a file that contains all of the auxiliary
* repository directories, and
* /lib/cpp is the name of the C preprocessor.
*
* You can also use the following options:
* -ptH".h, .H, .hxx, .HXX, .hh, .HH, .hpp" -- define the suffixes that
* ptlink will consider as a header file
* -ptS".c, .C, .cxx, .CXX, .cc, .CC, .cpp" -- define the suffixes that
* ptlink will consider as a source file
* -ptv -- be verbose (print lots of information about the various
* steps of instantiation)
* -pti -- compile the generated C files with the +i option, leaving the
* ..c files in the repository
* -pta -- change the instantiation rule to instantiate an entire template
* class at once rather that just the needed functions from a template
* class
* -ptk -- quit early if there are instantiation errors
*
*
* Functions:
* void pushstring(s) - push "char*" onto local stack "sstack"
* void popstring() - pop local stack "sstack"
* void handlesig() - print error message on SIGINT or SIGQUIT
*
* Fname* flookup(s, ftab) - look up name in hash table of file names

* linked in -- okobj() is always called before addobj()
* void addobj(nl, f, rep, on, fp) - add an object
* void fakelink(fp) - fake a link on the FILE pointed to by fp
* -- if the file is a .o file, all of the symbols are

* -- if the file is a .a file (library archive), only the
* symbols from the needed .o files are added to the
* symbol table
*

* int slp_subset(p1, p2, p3) - see if the list p1 is a subset of list p2,
* add to list p3 any members of list p1 that are not found in list p2

/* split the output of nm into fields */
/* The nm_split(buf, flds) function parses the buf argument (which is
assumed to be a line from the output of the "nm" command) and it modifies
the pointers in the array flds. The array flds should be a char* array
of at least two elements. flds[0] will point to a one-letter code
which indicates if the symbol is defined or undefined and whether it
is text, data, or common block. flds[1] will point to the symbol name.
The nm_split() function understands both System V and BSD nm formats.
(Most System V nm commands have a "Berkeley" mode (either -B or -p)
which is easier to parse and doesn't truncate very long symbols.)
There is a kludge in this function to skip over the initial "."
in a symbol name that is found in the IBM RS/6000 nm format.
The return values of nm_split() are as follows:
0 - this line defines a non-global symbol (usually ignored by the
function calling nm_split())
1 - this line defines a file (flds[0] is set to the file name)
If nm_split() is used on the nm output from an archive file, it
will find more that one file name within that output.
2 - this line defined a global symbol (flds[0] is set to the one-letter
typename for the symbol (U,D,T, or C), flds[1] is set to the symbol
name)
If nm_split() determines that the "nm" output is from a System V
nm command (heuristic: it's System V nm output if the line contains
at least one "|" character), then there will be some translation
required to get the one-letter codes for the type of each symbol.
SVR4:
We are only concerned with global symbols (field 4 == "GLOB").
If field 6 == "UNDEF", then the one-letter code is "U".
If field 6 == "COMMON", then the one-letter code is "C".
Otherwise, we look at field 3 -- if it's "FUNC", the one-letter
code is "T", otherwise it is "D".
Other System V:
We are only concerned with global symbols (field 2 == "extern").
If field 6 == ".text", then the one-letter code is "T".
If field 6 == ".data", then the one-letter code is "D".
Otherwise, we look at the address field (field 0). If it's "0",
the one-letter code is "C", otherwise it's "U".
BSD format:
We are not interested in the address field, only the type and
symbol fields. We are only concerned with global symbols
(one-letter code is a capital letter). There is a mapping of
some of the one-letter codes to simplify the rest of the software:
B, G, S --> D
E, c --> C
V --> U
Other mappings may be required for some operating systems that
have other single-letter types for external symbols in the nm
output -- this is one place where ptlink might have to be
modified in the future.

/* docomp(ptr, bbuf, ccpath, incl, ccopts, dip, prevcs, cpp)
An "instantiation file" is a .c file in the ptrepository directory
that is generated in the main loop of ptlink. Compiling the
instantiation file will generate an object file with either:
- the definitions of selected member functions of a template class, or
- the definition of a non-class template function
Some of the arguments of this function are passed along to fcomp() to
help build the correct command line.
ptr is the name of the repository
bbuf is the basename of the instantiation file
ccpath is the name of the CC command
incl is an Slist containing all of the -I options on the original command
ccopts is an Slist containing the other command line options
dip is an Slist containing the names of the member functions to instantiate
prevcs is the previous value of the checksum (used to determine whether
the compile is necessary, if you are using the CHECKSUM version of
ptlink) -- this value is normally obtained from the beginning of the
appropriate ".cs" file in the repository
cpp is the name of the C preprocessor
docomp() will write the new checksum in the appropriate ".cs" file (if
this is the CHECKSUM version of ptfilt), and it will update the list
of functions in the ".cs" file.

/* main -- the main program for ptlink has three major phases:
1. initialization
2. main loop
3. cleanup
In the initialization phase, main calls the following functions:
+-
| parse_ext() - to get the legal endings for header files and
| source files
| lock_rep() - to lock the repository
| tf_get() - to build a new "file table"
| read_mname() - to get defmap and any auxiliary map files (files that
| begin with "nmap" in the repository)
| - for each object file and library file on the link line, main calls:
| +-
| | readnm() - read all the symbols from an object file or a library
| | archive into an Obj structure. readnm() uses nm_split() to
| | parse each line of "nm" command output.
| | addfile() - add the filename to the global filename list
| | fadd() - add the basename of the file to a list of basenames
| +-
+-
In the main loop, the following functions are called:
+-
| tf_del() - clean up the file table
| tf_read() - read each of the map files
| symtab_del() - clean up the global symbol table
| fakelink() - build up the symbol table one file at a time
| fakelink() calls okobj(), addobj(), and lookup() as necessary
| getund() - builds a list of undefined template symbols
|
| - main() makes a list of template classes and functions based
| on the list generated by getund()
| - main() checks this list against a list that was saved from the
| last iteration of the loop. If they are the same, an "infinite
| loop" error message is printed and ptlink quits.
| - main() builds a new instantiation file for one of the items on
| the list
| - if the instantiation file is new, or it is different from
| the existing instantiation file for the given template class
| or function, main() overwrites the old instantiation file with
| the new instantiation file
|
| dodep() - check if the instantiation file must be recompiled.
| dodep() will call on docs() to compute checksums (in the
| CHECKSUM version) and build_cache() to build the header file
| cache files (in the non-CHECKSUM version) -- dodep() returns
| the name of a .o file to look for or build in a repository
| directory (in its "obuf" argument).
| add_lnobj() - add the name of the.o file that will be generated
| for the instantiation file to the list of objects to be linked
| docomp() [optional] - if dodep() determined that recompilation was
| required, docomp() will do it. docomp() will call on fcomp() to
| format the compile command line
| readnm(), addfile(), and fadd() - create a new Obj record for the
| new .o file and put the appropriate entry in the global Flist
+-
In the cleanup phase, main calls the following functions:
+-
| symtab_del() - clean up the global symbol table
| unlock_rep() - unlock the main repository
+-
