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> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
