[gdb] Fix 'not in executable format' error message
With trying to load a non-executable file into gdb, we run into PR26880: ... $ gdb -q -batch test.c "0x7ffc87bfc8d0s": not in executable format: \ file format not recognized ... The problem is caused by using %ps in combination with the error function (note that confusingly, it does work in combination with the warning function). Fix this by using plain "%s" instead. Tested on x86_64-linux. gdb/ChangeLog: 2021-08-22 Tom de Vries <tdevries@suse.de> PR gdb/26880 * gdb/exec.c (exec_file_attach): Use %s instead of %ps in call to error function. gdb/testsuite/ChangeLog: 2021-08-22 Tom de Vries <tdevries@suse.de> PR gdb/26880 * gdb.base/non-executable.exp: New file.
