Use stat, instead of strcmp, to check if the same linker script file appears multiple times for $ ld -L... -T ././/script.t -T script.t ... Although ././/script.t and script.t access the same file, but their filenames are different. strcmp won't work here. Copy gnulib/import/same-inode.h to include since the gnulib directory isn't included in the binutils tarball. include/ PR ld/24576 * same-inode.h: New file. Copied from gnulib/import/same-inode.h. ld/ PR ld/24576 * ldfile.c: Include "same-inode.h". (ldfile_find_command_file): Change the second argument from bool to enum script_open_style. Check if the same linker script file appears multiple times by using stat, instead using strcmp. (ldfile_open_command_file_1): Don't check if the same linker script file appears multiple times here. * testsuite/ld-scripts/pr24576-1.d: Adjusted. * testsuite/ld-scripts/pr24576-2.d: New. * testsuite/ld-scripts/script.exp: Run pr24576-2.
