From cb993c584c8ef91f5352ec9aa97d26fd76cfd643 Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Thu, 29 Sep 2011 20:25:46 -0700 Subject: Port --enable-checking=all to Fedora 14 x86. * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE): Move to lisp.h. (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc) (overrun_check_realloc, overrun_check_free): Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t). That way, xmalloc returns a properly-aligned pointer even if XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened to align OK on typical 64-bit hosts, but not on Fedora 14 x86. * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD into account when calculating the initial malloc maximum. * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE): Move here from alloc.c, so that charset.c can use it too. Properly align; the old code wasn't right for common 32-bit hosts when configured with --enable-checking=all. (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT) (XMALLOC_OVERRUN_SIZE_SIZE): New macros. --- src/ChangeLog | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) (limited to 'src/ChangeLog') diff --git a/src/ChangeLog b/src/ChangeLog index dcbeffac1b4..d6e5390c84f 100644 --- a/src/ChangeLog +++ b/src/ChangeLog @@ -1,3 +1,23 @@ +2011-09-30 Paul Eggert + + Port --enable-checking=all to Fedora 14 x86. + * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE): + Move to lisp.h. + (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc) + (overrun_check_realloc, overrun_check_free): + Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t). + That way, xmalloc returns a properly-aligned pointer even if + XMALLOC_OVERRUN_CHECK is defined.
