Just to report the result of the lang/rust testsuite on aarch64 with
commited devel/gdb :
test result: FAILED. 75 passed; 1 failed; 33 ignored; 0 measured; 0 filtered out
only one test is failing on 76 tests (so gdb works relatively well on aarch64,
thanks for that !).
rust-1.27.1/rustc-1.27.1-src/src/test/debuginfo/by-value-self-argument-in-trait-impl.rs
it tries to print self value in a Trait (extract of code source):
trait Trait {
fn method(self) -> Self;
}
impl Trait for (f64, isize, isize, f64) {
fn method(self) -> (f64, isize, isize, f64) {
zzz(); // #break
self
}
}
fn main() {
// ... others tests
let _ = (4444.5, 5555, 6666, 7777.5).method();
}
in gdb, in a break at zzz():
(gdb) print self
expected output:
$3 = (4444.5, 5555, 6666, 7777.5)
effective output:
$3 = (1.3580760565083671e-312, 3333, 274877654288,
1.3580760579708014e-312)
