--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Gaius Mulley <ga...@gcc.gnu.org>: https://gcc.gnu.org/g:3e9aaa9bcb2fc64e64f4e8a2aa0f6f7395a21c52 commit r13-7622-g3e9aaa9bcb2fc64e64f4e8a2aa0f6f7395a21c52 Author: Gaius Mulley <gaiusm...@gmail.com> Date: Fri Jul 28 15:00:29 2023 +0100 PR modula2/109729 cannot use a CHAR type as a FOR loop iterator This patch introduces a new quadruple ArithAddOp which is used in the construction of FOR loop to ensure that when constant folding is applied it does not concatenate two constant char operands into a string constant. Overloading only occurs with constant operands. gcc/m2/ChangeLog: PR modula2/109729 PR modula2/110246 * gm2-compiler/M2GenGCC.mod (CodeStatement): Detect ArithAddOp and call CodeAddChecked. (ResolveConstantExpressions): Detect ArithAddOp and call FoldArithAdd. (FoldArithAdd): New procedure. (FoldAdd): Refactor to use FoldArithAdd. * gm2-compiler/M2Quads.def (QuadOperator): Add ArithAddOp. * gm2-compiler/M2Quads.mod: Remove commented imports. (QuadFrame): Changed comments to use GNU coding standards. (ArithPlusTok): New global variable. (BuildForToByDo): Use ArithPlusTok instead of PlusTok. (MakeOp): Detect ArithPlusTok and return ArithAddOp. (WriteQuad): Add ArithAddOp clause. (WriteOperator): Add ArithAddOp clause. (Init): Initialize ArithPlusTok. gcc/testsuite/ChangeLog: PR modula2/109729 * gm2/pim/run/pass/ForChar.mod: New test.
