I am looking for some open source tools that have specific 32 to 64 bit code. The reason is that I am writing paper on porting 32 bit applications to 64 bit. When Digital introduced the 64 bit Alpha chip in the early 1990s, it modified lint by adding a specific mode to flag many 32 to 64 bit issues (I was the lint maintainer for the Alpha when OSF1/Digital Uniux/Tru64 Unix was released). For instance, the following code fragment: long n; int i = -2; unsigned k = 1; n = i + k; On a 32 bit system, n == -1, but on a 64 bit system n == 4294967295. This is because the expression (i + k) is an unsigned int expression, and when assigned to n, the sign will not extend. I'm looking for a tool or set of tools that might be able to find anomalies like this to help programmers port their applications to 64 bits. Note that GCC will flag some issue, but not specific 32 to 64 bit issues that are legal C or C++). -- Jerry Feldman <gaf@blu.org> Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9
