Invocation
and
Operation
of
the
TMS34010
C
Compiler
-I<dir>
The
=del
can be omitted, in
which
case name is defined
to
the value 1 .
This
option
can be used multiple times
for
defining
mul-
tiple names
by
separating the
-D
options
by
spaces.
(Uppercase
i) Adds dir to the list
of
directories
to
be
searched for
#include files. Omitting
dir
causes
option
-I
to be ignored. This option can
be
used mUltiple times,
each one separated by a space,
to
search more directories.
3.1.3
Operation
of
GSPCPP
GSPCPP maintains and recognizes the name -
-LlNE-
-
as
the current
line number
(a
decimal integer) and the name -
-FILE-
-
as
the current
file name
(a
C string). Note
that
these names begin
with
two
underscore
characters and end
with
two
underscore characters
with
no
spaces
be-
tween
the
characters.
You can use these names in the same
way
as
any
other defined
name,
including
using them in macros.
All
GSPCPP directives begin
with
the character
#,
which
must appear in
col-
umn 1.
Any
number
of
blanks and tabs are allowed between # and the
di-
rective name. The directives are described in Appendix
C,
and additional
information can be
found
in K&R.
The error messages produced
by
the preprocessor are self-explanatory; the line
number and the filename where the error occurred are printed along
with
the
diagnostic.
3.2
The
TMS34010
Parser
(GSPCC)
The parser, GSPCC, is the second pass
of
the C compiler.
It
reads
the
output
of
GSPCPP (the preprocessor), parses
it
perfo.rms syntax checking, and writes
an
intermediate file
for
input
to
the code generator (GSPCG).
3.2.1
Invoking
the
Parser
The parser
is
invoked
with
the
command:
~
[input
filel
[output
filel
1:.ll
where:
input
file
output
file
-z
is the name
of
the
input
file. The default extension
for
the
input
file
is
.cpp
if
none
is
specified.
If
no
input
file is given,
a
prompt
appears.
is
the name
of
the
output
file. This is
the
intermediate file
used
as
input
to
the GSPCG.
If
this argument is omitted, the
intermediate file is given the same name
as
the
input
file
with
the default extension .il.
is the
option
which
retains the
.cpp
input
file. The
.cpp
file
is
deleted
if
-z
is
not
specified. This parameter can be
placed anywhere in the invocation line.
