# This Awk script takes passes.def and writes pass-instances.def,
|
|
# counting the instances of each kind of pass, adding an instance number
|
|
# to everywhere that NEXT_PASS is used.
|
|
#
|
|
# For example, the single-instanced pass:
|
|
# NEXT_PASS (pass_warn_unused_result);
|
|
# becomes this in the output:
|
|
# NEXT_PASS (pass_warn_unused_result, 1);
|
|
#
|
|
# The various instances of
|
|
# NEXT_PASS (pass_copy_prop);
|
|
# become:
|
|
# NEXT_PASS (pass_copy_prop, 1);
|
|
# through:
|
|
# NEXT_PASS (pass_copy_prop, 8);
|
|
# (currently there are 8 instances of that pass)
|
|
|
|
# Usage: awk -f gen-pass-instances.awk passes.def
