Modified Files:
src/sys/lib/libsa: subr_prf.c
Log Message:
libsa/printf: Do not fetch long va_arg as long long.
This does real harm iff all of the following conditions are satisfied:
(1) On ILP32 architectures.
(2) Both LIBSA_PRINTF_LONGLONG_SUPPORT and LIBSA_PRINTF_WIDTH_SUPPORT
compile-time options are enabled.
(3) Width field is used with 'l' modifier.
This is an implicit-fallthrough bug, but unfortunately, GCC 10.4 cannot
find this out somehow...
XXX
Pull up to netbsd-10 and netbsd-9. netbsd-8 is not affected.
