--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Robert Dubner <[email protected]>: https://gcc.gnu.org/g:435346eafadece9d045874ba000cb4a53f625f0c commit r16-7853-g435346eafadece9d045874ba000cb4a53f625f0c Author: Robert Dubner <[email protected]> Date: Mon Mar 2 15:36:40 2026 -0500 cobol: Improved efficiency of code generated for MOVE "A" TO VAR(1:1). [119456] This PR rightly noted that COBOL source code which obviously could result in simple machine language did not. These changes take advantage of the compiler knowing, at compile time, the values of literal offsets and lengths, and uses that knowledge to generate much more efficient GENERIC for those cases. gcc/cobol/ChangeLog: PR cobol/119456 * genapi.cc (mh_source_is_literalA): Don't set refmod_e attribute unless it is necessary. (have_common_parent): Helper routine that determines whether two COBOL variables are members of the same data description. (mh_alpha_to_alpha): Modified for greater efficiency when table subscripts and reference modification parameters are numeric literals. * genutil.cc (get_data_offset): Recognizes when table subscripts and refmod offsets are numeric literals. (refer_size): Recognizes when refmod offsets are numeric literals. (refer_size_source): Recognizes when table subscripts are numeric literals.
