Fix ui constant tests for big-endian platforms

2022-12-27T14:23:15+00:00

A number of tests under ui/const-ptr and ui/consts are currently failing on big-endian platforms as the binary encoding of some constants is hard-coded in the stderr test files. Fix this by providing a normalize-stderr-test rule that strips out the raw bytes hex dump, so the comparison can be done in an endianness-independent manner. Note that in most cases, this means the tests are now also independent of word size, so the 32bit and 64bit cases can be re-unified. To keep tests that verify the details of those raw bytes dumps, a new test case raw-bytes.rs performs the tests where the hex dumps were stripped out a second time, but only on little- endian platforms. In addition, src/test/ui/const-ptr/forbidden_slices.rs exposes an endian-specific difference in this diagnostic output: constructing invalid value at .[0]: encountered 0x11, but expected a boolean depending on which byte of D0 is not a boolean value (0 or 1). Fixed this by choosing a value of D0 that differs from 0 or 1 in all bytes. Fixes part of https://github.com/rust-lang/rust/issues/105383.

Make non-power-of-two alignments a validity error in `Layout`

2022-04-09T03:17:38+00:00

Inspired by the zulip conversation about how `Layout` should better enforce `size < isize::MAX as usize`, this uses an N-variant enum on N-bit platforms to require at the validity level that the existing invariant of "must be a power of two" is upheld. This was MIRI can catch it, and means there's a more-specific type for `Layout` to store than just `NonZeroUsize`.

Rename stderr->64bit.stderr where needed.
