Ok for trunk and releases/gcc-14? -- The test case assumes that sizeof(tree_code) >= 2. On some targets, like Cortex-M on arm-none-eabi, -fshort-enums is enabled by default and in that case, sizeof(tree_code) will be 1 and the following warning is emitted: .../pr97315-1.C:8:13: warning: width of 'tree_base::code' exceeds its type Avoid the warning by forcing -fno-short-enums. gcc/testsuite/ChangeLog: * g++.dg/opt/pr97315-1.C: Add -fno-short-enums.
