Estimated hours taken: 0.25 Branches: main compiler/handle_options.m: scripts/final_grade_options.sh-subr: Make `--target il' imply `--high-level-data'. This is needed to ensure that the `--il' and `--target il' options select the `il' grade, which uses high-level data, rather than the `ilc' grade, which uses low-level data and which is no longer documented because it is not useful; high-level data is better for both efficiency and interoperability and for IL there are no advantages to low-level data.

# 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.
