In an aarch32-linux chroot on an aarch64-linux system, I run into: ... (gdb) print x^M $1 = 9223372036854775807^M (gdb) FAIL: gdb.ada/verylong.exp: print x ... A passing version on aarch64-linux looks like: ... (gdb) print x^M $1 = 170141183460469231731687303715884105727^M (gdb) PASS: gdb.ada/verylong.exp: print x ... The difference is caused by the size of the type Long_Long_Long_Integer, which is: - a 128-bit signed on 64-bit targets, and - a 64-bit signed on 32-bit target. Fix this by detecting the size of the Long_Long_Long_Integer type, and handling it. Tested on aarch64-linux and aarch32-linux.
