Visual Studio reports C4334 "was 64-bit shift intended" size mismatch warning because of size miss-match. Promote unity to the matching type to fit with the `&` operator. Signed-off-by: Philip Oakley <philipoakley@iee.email> --- This is the same fix that René Scharfe provided in 42c456ff81 (mergesort: avoid left shift overflow, 2021-11-16) Use size_t to match n when building the bitmask for checking whether a rank is occupied, instead of the default signed int. --- mergesort.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mergesort.c b/mergesort.c index 6216835566..bd9c6ef8ee 100644 --- a/mergesort.c +++ b/mergesort.c @@ -63,7 +63,7 @@ void *llist_mergesort(void *list, void *next = get_next_fn(list); if (next) set_next_fn(list, NULL); - for (i = 0; n & (1 << i); i++) + for (i = 0; n & ((size_t)1 << i); i++) list = llist_merge(ranks[i], list, get_next_fn, set_next_fn, compare_fn); n++; -- 2.34.0.rc1.windows.1.4.ga126985b17
