To identify the version number given an executable or object file created by the
Pascal compiler, use the following command.
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
-xl
option
•
pc0
, the Pascal front end
•
The global optimizer if you use the
-O
option
•
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.
hostname% mcs -p a.out | grep Pascal
