Estimated hours taken: 1 Branches: main compiler/handle_options.m: scripts/final_grade_options.sh-subr.m: Remove the implication from .debug to .tr. This implication is no longer appropriate, since we now have both .tr and .trseg versions of trailing, and .trseg is the more useful one. However, since .tr is still used, replacing the implication with one from .debug to .trseg is not appropriate either. Removing the implication yields an executable size reduction of 6.8%, and speedup of 10%.

# 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.
