- Subject: Question about building hash values from pointers
Hi,
as I noticed, most hash value calculations are trying to use pointer
values for building the value and assume that a long/unsigned long scalar
is wide enough for a pointer. This is at least for w64 target not true. So
I want to know, if it would be good to introduce an gcc specific type for
those kind of casts, or to use ssize_t/size_t.?
Regards,
Kai
Btw: I noticed that while trying to debug the native w64 compiler, which
always crashes in c-common.c:6748 in field_decl_cmp (a cross-compiler
version does not crash?!).
