|
|
|
This format is destined to change in the future, but for now a readable
|
|
form is more desirable than a compact form.
|
|
|
|
NOTES ABOUT THE P1 FORMAT
|
|
----------------------------------------------------------------------
|
|
|
|
P1_COMMENT: The comment string (in <data>) may be at most
|
|
COMMENT_BUFFER_SIZE bytes long. It must contain no newlines
|
|
or null characters. A side effect of the way comments are
|
|
read in lex.c is that no '\377' chars may be in a
|
|
comment either.
|
|
|
|
P1_SET_LINE: <data> holds the line number in the current source file.
|
|
|
|
P1_INC_LINE: Increment the source line number; <data> is empty.
|
|
|
|
P1_NAME_POINTER: <data> holds the integer representation of a
|
|
pointer into a hash table entry.
|
|
|
|
P1_CONST: the first field in <data> is a type tag (one of the
|
|
TYxxxx macros), the next field holds the constant
|
|
value
|
|
|
|
P1_EXPR: <data> holds the opcode number of the expression,
|
|
followed by the type of the expression (required for
|
|
OPCONV). Next is the value of vleng.
|
|
The type of operation represented by the
|
|
opcode determines how many of the following data items
|
|
are part of this expression.
|
|
|
|
P1_IDENT: <data> holds the type, then storage, then the
|
|
char string identifier in the addrp->user field.
|
|
|
|
P1_EXTERN: <data> holds an offset into the external symbol
|
|
table entry
|
|
|
|
P1_HEAD: the first field in <data> is the procedure class, the
|
|
second is the name of the procedure
|
|
|
|
P1_LIST: the first field in <data> is the tag, the second the
|
|
type of the list, the third the number of elements in
|
|
the list
|
|
|
|
P1_LITERAL: <data> holds the litnum of a value in the
|
|
literal pool.
|
|
|
|
P1_LABEL: <data> holds the statement number of the current
|
|
line
|
|
|
|
P1_ASGOTO: <data> holds the hash table pointer of the variable
|
|
|
|
P1_GOTO: <data> holds the statement number to jump to
|
|
|
|
P1_IF: <data> is empty, the following expression is the IF
|
|
condition.
|
|
|
|
P1_ELSE: <data> is empty.
|
|
|
|
P1_ELIF: <data> is empty, the following expression is the IF
|
|
condition.
|
|
|
|
P1_ENDIF: <data> is empty.
|
|
|
|
P1_ENDELSE: <data> is empty.
|
|
|
|
P1_ADDR: <data> holds a direct copy of the structure. The
|
|
next expression is a copy of vleng, and the next a
|
|
copy of memoffset.
|
|
|
|
P1_SUBR_RET: The next token is an expression for the return value.
|
|
|
|
P1_COMP_GOTO: The next token is an integer expression, the
|
|
following one a list of labels.
|
|
|
|
P1_FOR: The next three expressions are the Init, Test, and
|
|
Increment expressions of a C FOR loop.
|
|
|
|
P1_ENDFOR: Marks the end of the body of a FOR loop
|
