CVS commit: src/sys/lib/libsa

["Rin Okuyama" <rin%netbsd.org@localhost>]

Module Name:    src
Committed By:   rin
Date:           Mon May 29 03:56:52 UTC 2023

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.
