File gdb-testsuite-fix-gdb.ada-literals.exp-with-aarch64.patch of Package gdb.28855
[gdb/testsuite] Fix gdb.ada/literals.exp with aarch64 On aarch64-linux, I run into: ... (gdb) print 16#ffffffffffffffff#^M $7 = 18446744073709551615^M (gdb) FAIL: gdb.ada/literals.exp: print 16#ffffffffffffffff# ... while on x86_64-linux instead, I get: ... (gdb) print 16#ffffffffffffffff#^M $7 = -1^M (gdb) PASS: gdb.ada/literals.exp: print 16#ffffffffffffffff# ... We can easily reproduce this on x86_64-linux using: ... $ gdb -q -batch -ex "set lang ada" -ex "set arch i386" \ -ex "print 16#ffffffffffffffff#" $1 = -1 $ gdb -q -batch -ex "set lang ada" -ex "set arch aarch64" \ -ex "print 16#ffffffffffffffff#" $1 = 18446744073709551615 ... With i386, we have: ... (gdb) p int_bits $3 = 32 (gdb) p long_bits $4 = 32 (gdb) p long_long_bits $5 = 64 ... and so in processInt we hit the fits-in-unsigned-long-long case where we use as type long long: ... /* Note: Interprets ULLONG_MAX as -1. */ yylval.typed_val.type = type_long_long (par_state); ... With aarch64, we have instead: ... (gdb) p int_bits $1 = 32 (gdb) p long_bits $2 = 64 (gdb) p long_long_bits $3 = 64 ... and so in processInt we hit the fits-in-unsigned-long case where we use as type unsigned long: ... yylval.typed_val.type = builtin_type (par_state->gdbarch ())->builtin_unsigned_long; ... Fix this by updating the test-case to accept 18446744073709551615 as well. Tested on x86_64-linux and aarch64-linux.
