commit r16-5449-g722bd6847643ae5d3f66af2a68cc83374730bee6 Author: Xinhui Yang <[email protected]> Date: Tue Nov 11 10:19:35 2025 +0800 gcc: check if target install name equals the full driver name When a major version program suffix is specified, along with --with-gcc-major-version-only, GCC tries to install $TRIPLE-gcc-tmp into the destination BINDIR and link it to TRIPLE-gcc-SUFFIX. However this executable is installed in the previous step, thus leaving the gcc-tmp unmodified. This is because when --program-suffix=15 (any major version) and --with-gcc-major-version-only, $(version) will be the major version number, thus making FULL_DRIVER_NAME and GCC_TARGET_INSTALL_NAME identical to each other. We check if these two is identical and skip the latter step if they are. gcc/ PR bootstrap/105664 * Makefile.in (install-driver): detect name collision when installing the driver program.
