I've found a problem: use of %ld notation which is not an
invariant match to off_t and the like across FreeBSD
platforms: off_t is 64 bits across FreeBSD platoforms
but long is not (and so %ld is not):
+ xo_emit("=>{t:start/%*jd} {t:sectors/%*jd} {t:name/%*s} {:scheme} ({h:size/%ld}){t:state}\n",
. . .
+ xo_emit(" {t:start/%*jd} {t:sectors/%*jd} {P:/%*s} {ne:free}- free - ({h:size/%ld})\n",
. . .
+ xo_emit(" ({h:size/%ld})\n", pp->lg_mediasize);
. . .
+ xo_emit(" {t:start/%*jd} {t:sectors/%*jd} {P:/%*s} {ne:free}- free - ({h:size/%ld})\n",
%ld is for long but:
. . .
Architecture long void * long double time_t
aarch64 8 8 16 8
aarch64c 8 16 16 8
amd64 8 8 16 8
armv7 4 4 8 8
i386 4 4 12 4
. . .
The code would be broken in this way for i386 as well.
