Adds support for tracking original file and line numbers for better error reporting when a high-level language is translated into CIL. This adds a field called "hll_line" to struct cil_tree_node which increases memory usage by 5%. Syntax: ;;* lm(s|x) LINENO FILENAME (CIL STATEMENTS) ;;* lme lms is used when each of the following CIL statements corresponds to a line in the original file. lmx is used when the following CIL statements are all expanded from a single high-level language line. lme ends a line mark block. Example: ;;* lms 1 foo.hll (CIL-1) (CIL-2) ;;* lme ;;* lmx 10 bar.hll (CIL-3) (CIL-4) ;;* lms 100 baz.hll (CIL-5) (CIL-6) ;;* lme (CIL-7) ;;* lme CIL-1 is from line 1 of foo.hll CIL-2 is from line 2 of foo.hll CIL-3 is from line 10 of bar.hll CIL-4 is from line 10 of bar.hll CIL-5 is from line 100 of baz.hll CIL-6 is from line 101 of baz.hll CIL-7 is from line 10 of bar.hll Based on work originally done by Yuli Khodorkovskiy of Tresys.
