Subject: change underlying type of clock_t to be uniform and match ABI
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=5e642b5a2395893873affa2a121a694943b3f4e0;hp=5e642b5a2395893873affa2a121a694943b3f4e0

change underlying type of clock_t to be uniform and match ABI

previously we were using an unsigned type on 32-bit systems so that
subtraction would be well-defined when it wrapped, but since wrapping
is non-conforming anyway (when clock() overflows, it has to return -1)
the only use of unsigned would be to buy a little bit more time before
overflow. this does not seem worth having the type vary per-arch
(which leads to more arch-specific bugs) or disagree with the ABI musl
(mostly) follows.
