This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl vv5.9.3.
-----------------------------------------------------------------
[Please enter your report here]
The interpreter structure used by ithreads is defined at line 3959(ish) in
perl.h:
#if defined(MULTIPLICITY)
/* If we have multiple interpreters define a struct
holding variables which must be per-interpreter
If we don't have threads anything that would have
be per-thread is per-interpreter.
*/
struct interpreter {
# include "thrdvar.h"
# include "intrpvar.h"
/*
* The following is a buffer where new variables must
* be defined to maintain binary compatibility with previous versions
*/
PERLVARA(object_compatibility,30, char)
};
#else
...
For blead it doesn't need to be kept in order to maintain binary compatibility
with anything. Currently it doesn't have the most space efficient ordering -
in places there are odd numbers of 'char' elements between integers or
pointers, which means that there will be padding on nearly every architecture.
It would seem a good idea to re-order this and prune the odd unused entries.
thrdvar.h has this comment:
/* Important ones in the first cache line (if alignment is done right) */
so clearly some of the current ordering is important.
