--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jeff Law <l...@gcc.gnu.org>: https://gcc.gnu.org/g:0cd24b06d130d99bd86e5e03a01c38047413a92e commit r15-3947-g0cd24b06d130d99bd86e5e03a01c38047413a92e Author: Mikael Pettersson <mikpeli...@gmail.com> Date: Sun Sep 29 10:15:55 2024 -0600 [PATCH] [PATCH] Avoid integer overflow in gcc.dg/cpp/charconst-3.c (PR testsuite/116806) The intermediate expression (unsigned char) '\234' * scale overflows int on int16 targets, causing the test case to fail there. Fixed by performing the arithmetic in unsigned type, as suggested by Andrew Pinski. Regression tested on x86_64-pc-linux-gnu, and on an out-of-tree 16-bit target with simulator. Manually checked the generated code for pdp11 and xstormy16. Ok for trunk? (I don't have commit rights so I'd need help committing it.) gcc/testsuite/ PR testsuite/116806 * gcc.dg/cpp/charconst-3.c: Perform arithmetic in unsigned type to avoid integer overflow.
