Compile and Link Sequence

You can compile the file any.p with the following command-line:

hostname% pc any.p

This command actually invokes the compiler driver, which calls several programs or passes of the program, each of which processes the program. The output of each pass is the input to the next one.

After several passes, the object file any.o is created. An executable file is then generated with the default name a.out. Finally, the file any.o is removed.

pc calls:

•cpp, the C preprocessor or cppas, the preprocessor used when you use the -xloption

•pc0, the Pascal front end

•The global optimizer if you use the -Ooption

•cg, the code generator, which generates the relocatable object file

•pc3, which checks for conflicts in symbol names

•ld, the linker, which generates the executable files using any libraries necessary to resolve undefined symbols

The above is the default action of pc; some compiler options change what pc calls.
