It appears that every version of lib/libpmc/Makefile from head -r334242 and later has some variation of the odd nesting/value combinations that has "EVENT_ARCH" examples that are impossible to select as the code is structured. (The file version prior to -r334242 is from -r298107 .) === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
Weird conditional logic in lib/libpmc/Makefile
Hey all, Below is some logic pasted from lib/libpmc/Makefile: .if ${MACHINE_ARCH} == "amd64" || ${MACHINE_ARCH} == "i386" .if ${MACHINE_ARCH} == "aarch64" EVENT_ARCH="arm64" .elif ${MACHINE_ARCH} == "amd64" || ${MACHINE_ARCH} == "i386" EVENT_ARCH="x86" .elif ${MACHINE_ARCH} == "powerpc" EVENT_ARCH="powerpc" .endif JEVENTS= ${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+= libpmc_events.c .endif 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.
