Fix a bitwise negation assignment issue spotted by Sun Studio
Change direct and indirect assignments of the bitwise negation of 0 to
uint32_t variables to have a "U" suffix. I.e. ~0U instead of ~0. This
eliminates warnings under Sun Studio 12 Update 1:
"vcs-svn/string_pool.c", line 11: warning: initializer will be sign-extended: -1 (E_INIT_SIGN_EXTEND)
"vcs-svn/string_pool.c", line 81: warning: initializer will be sign-extended: -1 (E_INIT_SIGN_EXTEND)
"vcs-svn/repo_tree.c", line 112: warning: initializer will be sign-extended: -1 (E_INIT_SIGN_EXTEND)
"vcs-svn/repo_tree.c", line 112: warning: initializer will be sign-extended: -1 (E_INIT_SIGN_EXTEND)
"test-treap.c", line 34: warning: initializer will be sign-extended: -1 (E_INIT_SIGN_EXTEND)
The semantics are still the same as demonstrated by this program:
$ cat test.c && make test && ./test
#include <stdio.h>
#include <stdint.h>
int main(void)
{
uint32_t foo = ~0;
uint32_t bar = ~0U;
printf("foo = <%u> bar = <%u>\n", foo, bar);
return 0;
}
cc test.c -o test
"test.c", line 5: warning: initializer will be sign-extended: -1
foo = <4294967295> bar = <4294967295>
