Hi,

This is v2 of the patch.

Changes since v1: Fix indentation after removal of the conditional
statements, as suggested in review.

This patch removes redundant caller-side HAS_ROWS checks before calls to
a68_low_dup.

a68_low_dup originally always performed a deep copy, so callers avoided
invoking it for values without rows by checking HAS_ROWS beforehand.

a68_low_dup now performs its own HAS_ROWS check and returns the original
expression unchanged when a deep copy is not required. Remove the
remaining caller-side HAS_ROWS checks, as they are redundant.

Thanks,
Kanishka Solanki

Subject: [PATCH] remove redundant HAS_ROWS check from caller side of

Remove the remaining caller-side HAS_ROWS checks, as they are
redundant.

gcc/algol68/ChangeLog

	* a68-low-clauses.cc (a68_lower_collateral_clause): Do not check
	for rows before calling a68_low_dup.
	* a68-low-units.cc (collect_call_arguments): Likewise.
