expecting an int), but the disadvantage that an I32 is not 32 bits.
Andy Dougherty August 1996
- In the future, we may perhaps want to think about something like
- #if INTSIZE == 4
- typedef I32 int;
- #else
- # if LONGSIZE == 4
- typedef I32 long;
- # else
- # if SHORTSIZE == 4
- typedef I32 short;
- # else
- typedef I32 int;
- # endif
- # endif
- #endif
- For the moment, these are mentioned here so metaconfig will
- construct Configure to figure out the various sizes.
+ There is no guarantee that there is *any* integral type with
+ exactly 32 bits. It is perfectly legal for a system to have
+ sizeof(short) == sizeof(int) == sizeof(long) == 8.
+
+ Similarly, there is no guarantee that I16 and U16 have exactly 16
+ bits.
+
+ For dealing with issues that may arise from various 32/64-bit
+ systems, we will ask Configure to check out
+ SHORTSIZE == sizeof(short)
+ INTSIZE == sizeof(int)
+ LONGSIZE == sizeof(long)
+ LONGLONGSIZE == sizeof(long long) (if HAS_LONG_LONG)
+ PTRSIZE == sizeof(void *)
+ DOUBLESIZE == sizeof(double)
+ LONG_DOUBLESIZE == sizeof(long double) (if HAS_LONG_DOUBLE).
+ Most of these are currently unused, but they are mentioned here so
+ metaconfig will include the appropriate tests in Configure and
+ we can then start to consider how best to deal with long long
+ variables.
