With test-case gdb.ada/float-bits.exp and native we get: ... (gdb) print 16llf#7FFFF7FF4054A56FA5B99019A5C8#^M $9 = 5.0e+25^M (gdb) PASS: gdb.ada/float-bits.exp: print 16llf#7FFFF7FF4054A56FA5B99019A5C8# ... but with target board unix/-m32 we have instead: ... (gdb) print 16llf#7FFFF7FF4054A56FA5B99019A5C8#^M Cannot export value 2596145952482202326224873165792712 as 96-bits \ unsigned integer (must be between 0 and 79228162514264337593543950335)^M (gdb) FAIL: gdb.ada/float-bits.exp: print 16llf#7FFFF7FF4054A56FA5B99019A5C8# ... Fix this by testing whether 16llf is supported by doing ptype long_long_float which gets us either: ... type = <16-byte float>^M ... or: ... type = <12-byte float>^M ... Tested on x86_64-linux with native and unix/-m32. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=29041
