Hey all,
Below is some logic pasted from lib/libpmc/Makefile:
=2Eif ${MACHINE_ARCH} =3D=3D "amd64" || ${MACHINE_ARCH} =3D=3D "i386"
=2Eif ${MACHINE_ARCH} =3D=3D "aarch64"
EVENT_ARCH=3D"arm64"
=2Eelif ${MACHINE_ARCH} =3D=3D "amd64" || ${MACHINE_ARCH} =3D=3D "i386"
EVENT_ARCH=3D"x86"
=2Eelif ${MACHINE_ARCH} =3D=3D "powerpc"
EVENT_ARCH=3D"powerpc"
=2Eendif
JEVENTS=3D ${BTOOLSPATH:U.}/pmu-events/jevents
# This file is built in a subdirectory so never try to rebuild
# it here due to missing meta file.
${JEVENTS}: .NOMETA
libpmc_events.c: ${JEVENTS}
${JEVENTS} ${EVENT_ARCH} ${.CURDIR}/pmu-events/arch libpmc_events.c
SRCS+=3D libpmc_events.c
=2Eendif
Why perform the conditionals for aarch64 and powerpc when it can't be
those? "Am I missing something?
I'm looping in Matt Macy, who was the last person to touch the file.
Thanks,
