107 | |
108 | Currently, we only guarantee that I32 is *at least* 32 bits. |
109 | Specifically, if int is 64 bits, then so is I32. (This is the case |
110 | for the Cray.) This has the advantage of meshing nicely with |
111 | standard library calls (where we pass an I32 and the library is |
112 | expecting an int), but the disadvantage that an I32 is not 32 bits. |

115 | There is no guarantee that there is *any* integral type with |
116 | exactly 32 bits. It is perfectly legal for a system to have |
117 | sizeof(short) == sizeof(int) == sizeof(long) == 8. |
693762b4 |
118 | |

119 | Similarly, there is no guarantee that I16 and U16 have exactly 16 |
120 | bits. |

656 | * If PERL_MEM_LOG is defined, all Newx()s, Renew()s, and Safefree()s |
46c6c7e2 |
657 | * go through functions, which are handy for debugging breakpoints, but |
658 | * which more importantly get the immediate calling environment (file and |
e352bcff |
659 | * line number, and C function name if available) passed in. This info can |
660 | * then be used for logging the calls, for which one gets a sample |
661 | * implementation if PERL_MEM_LOG_STDERR is defined. |

46c6c7e2 |
663 | * Known problems: |
664 | * - all memory allocs do not get logged, only those |
665 | * that go through Newx() and derivatives (while all |
666 | * Safefrees do get logged) |
667 | * - __FILE__ and __LINE__ do not work everywhere |
668 | * - __func__ or __FUNCTION__ even less so |
669 | * - I think more goes on after the perlio frees but |
670 | * the thing is that STDERR gets closed (as do all |
671 | * the file descriptors) |
672 | * - no deeper calling stack than the caller of the Newx() |
673 | * or the kind, but do I look like a C reflection/introspection |
674 | * utility to you? |
675 | * - the function prototypes for the logging functions |
676 | * probably should maybe be somewhere else than handy.h |
677 | * - one could consider inlining (macrofying) the logging |
678 | * for speed, but I am too lazy |
679 | * - one could imagine recording the allocations in a hash, |
680 | * (keyed by the allocation address?), and maintain that |
681 | * through reallocs and frees, but how to do that without |
682 | * any News() happening...? |
