/* Usage suggestions:
Programs that use <stdbool.h> should be aware of some limitations
and standards compliance issues.
Standards compliance:
- <stdbool.h> must be #included before 'bool', 'false', 'true'
can be used.
- You cannot assume that sizeof (bool) == 1.
- Programs should not undefine the macros bool, true, and false,
as C99 lists that as an "obsolescent feature".
Limitations of this substitute, when used in a C89 environment:
- <stdbool.h> must be #included before the '_Bool' type can be used.
- You cannot assume that _Bool is a typedef; it might be a macro.
- Bit-fields of type 'bool' are not supported. Portable code
should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
- In C99, casts and automatic conversions to '_Bool' or 'bool' are
performed in such a way that every nonzero value gets converted
to 'true', and zero gets converted to 'false'. This doesn't work
with this substitute. With this substitute, only the values 0 and 1
give the expected result when converted to _Bool' or 'bool'.
Also, it is suggested that programs use 'bool' rather than '_Bool';
this isn't required, but 'bool' is more common. */

It is tempting to write
typedef enum { false = 0, true = 1 } _Bool;
so that gdb prints values of type 'bool' symbolically. But if we do
this, values of type '_Bool' may promote to 'int' or 'unsigned int'
(see ISO C 99 6.7.2.2.(4)); however, '_Bool' must promote to 'int'
(see ISO C 99 6.3.1.1.(2)). So we add a negative value to the
enum; this ensures that '_Bool' promotes to 'int'. */

So we override the _Bool type.
If !@HAVE__BOOL@:
Need to define _Bool ourselves. As 'signed char' or as an enum type?
Use of a typedef, with SunPRO C, leads to a stupid
"warning: _Bool is a keyword in ISO C99".
Use of an enum type, with IRIX cc, leads to a stupid
"warning(1185): enumerated type mixed with another type".
Even the existence of an enum type, without a typedef,
"Invalid enumerator. (badenum)" with HP-UX cc on Tru64.
The only benefit of the enum, debuggability, is not important
with these compilers. So use 'signed char' and no enum. */

#ifndef VERIFY_H
# define VERIFY_H 1
/* Each of these macros verifies that its argument R is nonzero. To
be portable, R should be an integer constant expression. Unlike
assert (R), there is no run-time overhead.
There are two macros, since no single macro can be used in all
contexts in C. verify_true (R) is for scalar contexts, including
integer constant expression contexts. verify (R) is for declaration
contexts, e.g., the top level.
Symbols ending in "__" are private to this header.
The code below uses several ideas.
* The first step is ((R) ? 1 : -1). Given an expression R, of
integral or boolean or floating-point type, this yields an
expression of integral type, whose value is later verified to be
constant and nonnegative.
* Next this expression W is wrapped in a type
struct verify_type__ { unsigned int verify_error_if_negative_size__: W; }.
If W is negative, this yields a compile-time error. No compiler can
deal with a bit-field of negative size.
One might think that an array size check would have the same
effect, that is, that the type struct { unsigned int dummy[W]; }
would work as well. However, inside a function, some compilers
(such as C++ compilers and GNU C) allow local parameters and
variables inside array size expressions. With these compilers,
an array size check would not properly diagnose this misuse of
the verify macro:
void function (int n) { verify (n < 0); }
* For the verify macro, the struct verify_type__ will need to
somehow be embedded into a declaration. To be portable, this
declaration must declare an object, a constant, a function, or a
typedef name. If the declared entity uses the type directly,
such as in
struct dummy {...};
typedef struct {...} dummy;
extern struct {...} *dummy;
extern void dummy (struct {...} *);
extern struct {...} *dummy (void);
two uses of the verify macro would yield colliding declarations
if the entity names are not disambiguated. A workaround is to
attach the current line number to the entity name:
#define GL_CONCAT0(x, y) x##y
#define GL_CONCAT(x, y) GL_CONCAT0 (x, y)
extern struct {...} * GL_CONCAT(dummy,__LINE__);
But this has the problem that two invocations of verify from
within the same macro would collide, since the __LINE__ value
would be the same for both invocations.
A solution is to use the sizeof operator. It yields a number,
getting rid of the identity of the type. Declarations like
extern int dummy [sizeof (struct {...})];
extern void dummy (int [sizeof (struct {...})]);
extern int (*dummy (void)) [sizeof (struct {...})];
can be repeated.
* Should the implementation use a named struct or an unnamed struct?
Which of the following alternatives can be used?
extern int dummy [sizeof (struct {...})];
extern int dummy [sizeof (struct verify_type__ {...})];
extern void dummy (int [sizeof (struct {...})]);
extern void dummy (int [sizeof (struct verify_type__ {...})]);
extern int (*dummy (void)) [sizeof (struct {...})];
extern int (*dummy (void)) [sizeof (struct verify_type__ {...})];
In the second and sixth case, the struct type is exported to the
outer scope; two such declarations therefore collide. GCC warns
about the first, third, and fourth cases. So the only remaining
possibility is the fifth case:
extern int (*dummy (void)) [sizeof (struct {...})];
* This implementation exploits the fact that GCC does not warn about
the last declaration mentioned above. If a future version of GCC
introduces a warning for this, the problem could be worked around
by using code specialized to GCC, e.g.,:
#if 4 <= __GNUC__
# define verify(R) \
extern int (* verify_function__ (void)) \
[__builtin_constant_p (R) && (R) ? 1 : -1]
#endif
* In C++, any struct definition inside sizeof is invalid.
Use a template type to work around the problem. */
