gcc/ChangeLog: 2019-08-13 Jozef Lawrynowicz <jozef.l@mittosystems.com> * config/msp430/driver-msp430.c (msp430_set_driver_var): New. * config/msp430/msp430-devices.c (canonicalize_path_dirsep): New. (msp430_check_path_for_devices): New. (parse_devices_csv_1): New. (parse_devices_csv): New. (msp430_extract_mcu_data): Try to find devices.csv and search for the MCU data in devices.csv before using the hard-coded data. Warn if devices.csv isn't found and the MCU wasn't found in the hard-coded data either. * config/msp430/msp430.h (DRIVER_SELF_SPECS): Call msp430_set_driver_var for -mno-warn-devices-csv and -mdevices-csv-loc. Search for devices.csv on -I and -L paths. (EXTRA_SPEC_FUNCTIONS): Add msp430_check_path_for_devices and msp430_set_driver_var. * config/msp430/msp430.opt: Add -mwarn-devices-csv and -mdevices-csv-loc=. * doc/invoke.texi (-mmcu): Document that -I and -L paths are searched for devices.csv. (mwarn-devices-csv): Document option. gcc/testsuite/ChangeLog: 2019-08-13 Jozef Lawrynowicz <jozef.l@mittosystems.com> * gcc.target/msp430/msp430.exp (msp430_device_permutations_runtest): Handle csv-* and bad-devices-* tests. * gcc.target/msp430/devices/README: Document how bad-devices-* tests work. * gcc.target/msp430/devices/bad-devices-1.c: New test. * gcc.target/msp430/devices/bad-devices-2.c: Likewise. * gcc.target/msp430/devices/bad-devices-3.c: Likewise. * gcc.target/msp430/devices/bad-devices-4.c: Likewise. * gcc.target/msp430/devices/bad-devices-5.c: Likewise. * gcc.target/msp430/devices/bad-devices-6.c: Likewise. * gcc.target/msp430/devices/csv-device-order.c: Likewise. * gcc.target/msp430/devices/csv-msp430_00.c: Likewise. * gcc.target/msp430/devices/csv-msp430_01.c: Likewise. * gcc.target/msp430/devices/csv-msp430_02.c: Likewise. * gcc.target/msp430/devices/csv-msp430_04.c: Likewise. * gcc.target/msp430/devices/csv-msp430_08.c: Likewise. * gcc.target/msp430/devices/csv-msp430_10.c: Likewise. * gcc.target/msp430/devices/csv-msp430_11.c: Likewise. * gcc.target/msp430/devices/csv-msp430_12.c: Likewise. * gcc.target/msp430/devices/csv-msp430_14.c: Likewise. * gcc.target/msp430/devices/csv-msp430_18.c: Likewise. * gcc.target/msp430/devices/csv-msp430_20.c: Likewise. * gcc.target/msp430/devices/csv-msp430_21.c: Likewise. * gcc.target/msp430/devices/csv-msp430_22.c: Likewise. * gcc.target/msp430/devices/csv-msp430_24.c: Likewise. * gcc.target/msp430/devices/csv-msp430_28.c: Likewise. * gcc.target/msp430/devices/csv-msp430fr5969.c: Likewise. * gcc.target/msp430/devices/hard-foo.c: Likewise. * gcc.target/msp430/devices/bad-devices-1.csv: New test support file. * gcc.target/msp430/devices/bad-devices-2.csv: Likewise. * gcc.target/msp430/devices/bad-devices-3.csv: Likewise. * gcc.target/msp430/devices/bad-devices-4.csv: Likewise. * gcc.target/msp430/devices/bad-devices-5.csv: Likewise. * gcc.target/msp430/devices/bad-devices-6.csv: Likewise. * gcc.target/msp430/devices/devices.csv: Likewise.
