--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Gaius Mulley <ga...@gcc.gnu.org>: https://gcc.gnu.org/g:73cc6ce1294ec35e9322b1bbc91009cfc76f732b commit r14-2725-g73cc6ce1294ec35e9322b1bbc91009cfc76f732b Author: Gaius Mulley <gaiusm...@gmail.com> Date: Sat Jul 22 10:01:02 2023 +0100 PR modula2/110631 Bugfix to FIO WriteCardinal FIO.WriteCardinal fails to write binary data. This patch fixes two bugs in FIO.mod and provides a testcase which writes and reads binary cardinals. There was an off by one error when using HIGH (a) to determine the number of bytes and the dest/src pointers were switched when calling memcpy. gcc/m2/ChangeLog: PR modula2/110631 * gm2-libs/FIO.def (ReadAny): Correct comment as HIGH (a) + 1 is number of bytes. (WriteAny): Correct comment as HIGH (a) + 1 is number of bytes. * gm2-libs/FIO.mod (ReadAny): Correct comment as HIGH (a) + 1 is number of bytes. Also pass HIGH (a) + 1 to BufferedRead. (WriteAny): Correct comment as HIGH (a) + 1 is number of bytes. Also pass HIGH (a) + 1 to BufferedWrite. (BufferedWrite): Rename parameter a to src, rename variable t to dest. Correct parameter order to memcpy. gcc/testsuite/ChangeLog: PR modula2/110631 * gm2/pimlib/run/pass/testfiobinary.mod: New test. Signed-off-by: Gaius Mulley <gaiusm...@gmail.com>
