scripts/final_grade_options.sh-subr: Print an error and exit with a non-zero exit status for various invalid grade component combinations. Implicitly disable the .par component for the non-C backends. This doesn't affect the support for threads in grades that use these backends.

# final_grade_options.sh-subr:
|
|
# An `sh' subroutine for handling implications between grade-related
|
|
# options. Used by the `ml', `mgnuc' and `c2init' scripts.
|
|
#
|
|
# The code here should be inserted after a script's option-parsing
|
|
# loop.
|
|
#
|
|
# IMPORTANT: any changes to the handling of grades here may also require
|
|
# changes to compiler/handle_options.m.

# This file should only use the shell variables initialized by

# init_grade_options.sh-subr.
