tools/make_optimization_options:
Instead of generating a file to be manually copied into the middle
of compiler/options.m, do that update automatically.
compiler/options.m:
Mark both ends of the region whose contents are controlled by
tools/make_optimization_options.

# This script constructs (or reconstructs) the contents of
|

# compiler/optimization_options.m. The initial and final parts
|
|
# are hand_written, in make_optimization_options_{start,end}
|
|
# respectively, while the middle is generated by
|
|
# make_optimization_options_middle from make_optimization_options_db.

|
#
|
|
# make_optimization_options_middle also reconstructs the contents of
|

# compiler/options.m. Specifically, it rewrites the part between two markers,
|
|
# INCLUDE_HANDLER_FILE_START and INCLUDE_HANDLER_FILE_END, which contains
|
|
# the code handling the bool_special, int_special etc optimization options.
