Rich Felker 0958200166 very cheap double-free checks in malloc 2011-03-23 13:24:00 -04:00
Rich Felker aa398f56fa global cleanup to use the new syscall interface 2011-03-20 00:16:43 -04:00
Rich Felker 26031da0f8 make malloc(0) return unique pointers rather than NULL 
this change is made with some reluctance, but i think it's for the
best. correct programs must handle either behavior, so there is little
advantage to having malloc(0) return NULL. and i managed to actually
make the malloc code slightly smaller with this change.

Rich Felker 598a0147cd fix simple_malloc malloc(0) behavior not to return non-unique pointers 2011-02-20 16:12:09 -05:00
Rich Felker a23baf586a fix simple_malloc size restrictions 
do not allow allocations that overflow ptrdiff_t; fix some overflow
checks that were not quite right but didn't matter due to address
layout implementation.
