Ugly Assigned Labels
--------------------
The `-fugly-assign' option forces `g77' to use the same storage for
assigned labels as it would for a normal assignment to the same
variable.
For example, consider the following code fragment:
I = 3
ASSIGN 10 TO I
Normally, for portability and improved diagnostics, `g77' reserves
distinct storage for a "sibling" of `I', used only for `ASSIGN'
statements to that variable (along with the corresponding
assigned-`GOTO' and assigned-`FORMAT'-I/O statements that reference the
variable).
However, some code (that violates the ANSI FORTRAN 77 standard)
attempts to copy assigned labels among variables involved with `ASSIGN'
statements, as in:
ASSIGN 10 TO I
ISTATE(5) = I
...
J = ISTATE(ICUR)
GOTO J
Such code doesn't work under `g77' unless `-fugly-assign' is specified
on the command-line, ensuring that the value of `I' referenced in the
second line is whatever value `g77' uses to designate statement label
`10', so the value may be copied into the `ISTATE' array, later
retrieved into a variable of the appropriate type (`J'), and used as
the target of an assigned-`GOTO' statement.
*Note:* To avoid subtle program bugs, when `-fugly-assign' is
specified, `g77' requires the type of variables specified in
assigned-label contexts *must* be the same type returned by `%LOC()'.
On many systems, this type is effectively the same as
`INTEGER(KIND=1)', while, on others, it is effectively the same as
`INTEGER(KIND=2)'.
Do *not* depend on `g77' actually writing valid pointers to these
variables, however. While `g77' currently chooses that implementation,
it might be changed in the future.
*Note Assigned Statement Labels (ASSIGN and GOTO): Assigned
Statement Labels, for implementation details on assigned-statement
labels.

The GNU Fortran Compiler
************************
The GNU Fortran compiler, `g77', supports programs written in the
GNU Fortran language and in some other dialects of Fortran.
Some aspects of how `g77' works are universal regardless of dialect,
and yet are not properly part of the GNU Fortran language itself.
These are described below.
*Note: This portion of the documentation definitely needs a lot of
work!*

* Compiler Constants::

Compiler Limits
===============
`g77', as with GNU tools in general, imposes few arbitrary
restrictions on lengths of identifiers, number of continuation lines,
number of external symbols in a program, and so on.
For example, some other Fortran compiler have an option (such as
`-NlX') to increase the limit on the number of continuation lines.
Also, some Fortran compilation systems have an option (such as `-NxX')
to increase the limit on the number of external symbols.
`g77', `gcc', and GNU `ld' (the GNU linker) have no equivalent
options, since they do not impose arbitrary limits in these areas.
`g77' does currently limit the number of dimensions in an array to
the same degree as do the Fortran standards--seven (7). This
restriction might well be lifted in a future version.
File: g77.info, Node: Compiler Types, Next: Compiler Constants, Prev: Compiler Limits, Up: Compiler
Compiler Types
==============
Fortran implementations have a fair amount of freedom given them by
the standard as far as how much storage space is used and how much
precision and range is offered by the various types such as
`LOGICAL(KIND=1)', `INTEGER(KIND=1)', `REAL(KIND=1)', `REAL(KIND=2)',
`COMPLEX(KIND=1)', and `CHARACTER'. Further, many compilers offer
so-called `*N' notation, but the interpretation of N varies across
compilers and target architectures.
The standard requires that `LOGICAL(KIND=1)', `INTEGER(KIND=1)', and
`REAL(KIND=1)' occupy the same amount of storage space, and that
`COMPLEX(KIND=1)' and `REAL(KIND=2)' take twice as much storage space
as `REAL(KIND=1)'. Further, it requires that `COMPLEX(KIND=1)'
entities be ordered such that when a `COMPLEX(KIND=1)' variable is
storage-associated (such as via `EQUIVALENCE') with a two-element
`REAL(KIND=1)' array named `R', `R(1)' corresponds to the real element
and `R(2)' to the imaginary element of the `COMPLEX(KIND=1)' variable.
(Few requirements as to precision or ranges of any of these are
placed on the implementation, nor is the relationship of storage sizes
of these types to the `CHARACTER' type specified, by the standard.)
`g77' follows the above requirements, warning when compiling a
program requires placement of items in memory that contradict the
requirements of the target architecture. (For example, a program can
require placement of a `REAL(KIND=2)' on a boundary that is not an even
multiple of its size, but still an even multiple of the size of a
`REAL(KIND=1)' variable. On some target architectures, using the
canonical mapping of Fortran types to underlying architectural types,
such placement is prohibited by the machine definition or the
Application Binary Interface (ABI) in force for the configuration
defined for building `gcc' and `g77'. `g77' warns about such
situations when it encounters them.)
`g77' follows consistent rules for configuring the mapping between
Fortran types, including the `*N' notation, and the underlying
architectural types as accessed by a similarly-configured applicable
version of the `gcc' compiler. These rules offer a widely portable,
consistent Fortran/C environment, although they might well conflict
with the expectations of users of Fortran compilers designed and
written for particular architectures.
These rules are based on the configuration that is in force for the
version of `gcc' built in the same release as `g77' (and which was
therefore used to build both the `g77' compiler components and the
`libf2c' run-time library):
`REAL(KIND=1)'
Same as `float' type.
`REAL(KIND=2)'
Same as whatever floating-point type that is twice the size of a
`float'--usually, this is a `double'.
`INTEGER(KIND=1)'
Same as an integral type that is occupies the same amount of
memory storage as `float'--usually, this is either an `int' or a
`long int'.
`LOGICAL(KIND=1)'
Same `gcc' type as `INTEGER(KIND=1)'.
`INTEGER(KIND=2)'
Twice the size, and usually nearly twice the range, as
`INTEGER(KIND=1)'--usually, this is either a `long int' or a `long
long int'.
`LOGICAL(KIND=2)'
Same `gcc' type as `INTEGER(KIND=2)'.
`INTEGER(KIND=3)'
Same `gcc' type as signed `char'.
`LOGICAL(KIND=3)'
Same `gcc' type as `INTEGER(KIND=3)'.
`INTEGER(KIND=6)'
Twice the size, and usually nearly twice the range, as
`INTEGER(KIND=3)'--usually, this is a `short'.
`LOGICAL(KIND=6)'
Same `gcc' type as `INTEGER(KIND=6)'.
`COMPLEX(KIND=1)'
Two `REAL(KIND=1)' scalars (one for the real part followed by one
for the imaginary part).
`COMPLEX(KIND=2)'
Two `REAL(KIND=2)' scalars.
`NUMERIC-TYPE*N'
(Where NUMERIC-TYPE is any type other than `CHARACTER'.) Same as
whatever `gcc' type occupies N times the storage space of a `gcc'
`char' item.
`DOUBLE PRECISION'
Same as `REAL(KIND=2)'.
`DOUBLE COMPLEX'
Same as `COMPLEX(KIND=2)'.
Note that the above are proposed correspondences and might change in
future versions of `g77'--avoid writing code depending on them.
Other types supported by `g77' are derived from gcc types such as
`char', `short', `int', `long int', `long long int', `long double', and
so on. That is, whatever types `gcc' already supports, `g77' supports
now or probably will support in a future version. The rules for the
`NUMERIC-TYPE*N' notation apply to these types, and new values for
`NUMERIC-TYPE(KIND=N)' will be assigned in a way that encourages
clarity, consistency, and portability.
File: g77.info, Node: Compiler Constants, Next: Compiler Intrinsics, Prev: Compiler Types, Up: Compiler
Compiler Constants
==================
`g77' strictly assigns types to *all* constants not documented as
"typeless" (typeless constants including `'1'Z', for example). Many
other Fortran compilers attempt to assign types to typed constants
based on their context. This results in hard-to-find bugs, nonportable
code, and is not in the spirit (though it strictly follows the letter)
of the 77 and 90 standards.
`g77' might offer, in a future release, explicit constructs by which
a wider variety of typeless constants may be specified, and/or
user-requested warnings indicating places where `g77' might differ from
how other compilers assign types to constants.
*Note Context-Sensitive Constants::, for more information on this
issue.
File: g77.info, Node: Compiler Intrinsics, Prev: Compiler Constants, Up: Compiler
Compiler Intrinsics
===================
`g77' offers an ever-widening set of intrinsics. Currently these
all are procedures (functions and subroutines).
Some of these intrinsics are unimplemented, but their names reserved
to reduce future problems with existing code as they are implemented.
Others are implemented as part of the GNU Fortran language, while yet
others are provided for compatibility with other dialects of Fortran
but are not part of the GNU Fortran language.
To manage these distinctions, `g77' provides intrinsic *groups*, a
facility that is simply an extension of the intrinsic groups provided
by the GNU Fortran language.
* Menu:
* Intrinsic Groups:: How intrinsics are grouped for easy management.
* Other Intrinsics:: Intrinsics other than those in the GNU
Fortran language.
File: g77.info, Node: Intrinsic Groups, Next: Other Intrinsics, Up: Compiler Intrinsics
Intrinsic Groups
----------------
A given specific intrinsic belongs in one or more groups. Each
group is deleted, disabled, hidden, or enabled by default or a
command-line option. The meaning of each term follows.
Deleted
No intrinsics are recognized as belonging to that group.
Disabled
Intrinsics are recognized as belonging to the group, but
references to them (other than via the `INTRINSIC' statement) are
disallowed through that group.
Hidden
Intrinsics in that group are recognized and enabled (if
implemented) *only* if the first mention of the actual name of an
intrinsic in a program unit is in an `INTRINSIC' statement.
Enabled
Intrinsics in that group are recognized and enabled (if
implemented).
The distinction between deleting and disabling a group is illustrated
by the following example. Assume intrinsic `FOO' belongs only to group
`FGR'. If group `FGR' is deleted, the following program unit will
successfully compile, because `FOO()' will be seen as a reference to an
external function named `FOO':
PRINT *, FOO()
END
If group `FGR' is disabled, compiling the above program will produce
diagnostics, either because the `FOO' intrinsic is improperly invoked
or, if properly invoked, it is not enabled. To change the above
program so it references an external function `FOO' instead of the
disabled `FOO' intrinsic, add the following line to the top:
EXTERNAL FOO
So, deleting a group tells `g77' to pretend as though the intrinsics in
that group do not exist at all, whereas disabling it tells `g77' to
recognize them as (disabled) intrinsics in intrinsic-like contexts.
Hiding a group is like enabling it, but the intrinsic must be first
named in an `INTRINSIC' statement to be considered a reference to the
intrinsic rather than to an external procedure. This might be the
"safest" way to treat a new group of intrinsics when compiling old
code, because it allows the old code to be generally written as if
those new intrinsics never existed, but to be changed to use them by
inserting `INTRINSIC' statements in the appropriate places. However,
it should be the goal of development to use `EXTERNAL' for all names of
external procedures that might be intrinsic names.
If an intrinsic is in more than one group, it is enabled if any of
its containing groups are enabled; if not so enabled, it is hidden if
any of its containing groups are hidden; if not so hidden, it is
disabled if any of its containing groups are disabled; if not so
disabled, it is deleted. This extra complication is necessary because
some intrinsics, such as `IBITS', belong to more than one group, and
hence should be enabled if any of the groups to which they belong are
enabled, and so on.
The groups are:
`badu77'
UNIX intrinsics having inappropriate forms (usually functions that
have intended side effects).
`gnu'
Intrinsics the GNU Fortran language supports that are extensions to
the Fortran standards (77 and 90).
`f2c'
Intrinsics supported by AT&T's `f2c' converter and/or `libf2c'.
`f90'
Fortran 90 intrinsics.
`mil'
MIL-STD 1753 intrinsics (`MVBITS', `IAND', `BTEST', and so on).
`unix'
UNIX intrinsics (`IARGC', `EXIT', `ERF', and so on).
`vxt'
VAX/VMS FORTRAN (current as of v4) intrinsics.

MODE, which is given in the format of `chmod(1)'. A null character
(`CHAR(0)') marks the end of the name in NAME--otherwise, trailing
blanks in NAME are ignored. Currently, NAME must not contain the
single quote character.
Returns 0 on success or a non-zero error code otherwise.
Note that this currently works by actually invoking `/bin/chmod' (or
the `chmod' found when the library was configured) and so may fail in
some circumstances and will, anyway, be slow.
Due to the side effects performed by this intrinsic, the function
form is not recommended.

DCmplx Intrinsic
................
DCmplx(X, Y)
DCmplx: `COMPLEX(KIND=2)' function.
X: `INTEGER', `REAL', or `COMPLEX'; scalar; INTENT(IN).
Y: `INTEGER' or `REAL'; OPTIONAL (must be omitted if X is `COMPLEX');
scalar; INTENT(IN).
Intrinsic groups: `f2c', `vxt'.
Description:
If X is not type `COMPLEX', constructs a value of type
`COMPLEX(KIND=2)' from the real and imaginary values specified by X and
Y, respectively. If Y is omitted, `0D0' is assumed.
If X is type `COMPLEX', converts it to type `COMPLEX(KIND=2)'.
Although this intrinsic is not standard Fortran, it is a popular
extension offered by many compilers that support `DOUBLE COMPLEX',
since it offers the easiest way to convert to `DOUBLE COMPLEX' without
using Fortran 90 features (such as the `KIND=' argument to the
`CMPLX()' intrinsic).
(`CMPLX(0D0, 0D0)' returns a single-precision `COMPLEX' result, as
required by standard FORTRAN 77. That's why so many compilers provide
`DCMPLX()', since `DCMPLX(0D0, 0D0)' returns a `DOUBLE COMPLEX' result.
Still, `DCMPLX()' converts even `REAL*16' arguments to their `REAL*8'
equivalents in most dialects of Fortran, so neither it nor `CMPLX()'
allow easy construction of arbitrary-precision values without
potentially forcing a conversion involving extending or reducing
precision. GNU Fortran provides such an intrinsic, called `COMPLEX()'.)

Description:
Converts A to `REAL(KIND=2)'.
If A is type `COMPLEX', its real part is converted (if necessary) to
`REAL(KIND=2)', and its imaginary part is disregarded.
Although this intrinsic is not standard Fortran, it is a popular
extension offered by many compilers that support `DOUBLE COMPLEX',
since it offers the easiest way to extract the real part of a `DOUBLE
COMPLEX' value without using the Fortran 90 `REAL()' intrinsic in a way
that produces a return value inconsistent with the way many FORTRAN 77
compilers handle `REAL()' of a `DOUBLE COMPLEX' value.
