At some point, I had thought to use this code to handle equality
comparisons for the `IfEq` verify bounds; at that point, we might not
have had an infcx to talk about. But we wound up doing "SCC
representatives" instead, so that's fine.
clarify pointer add/sub function safety concerns
Ralf Jung made the same changes to the offset functions' documentation
in commit fb089156. As add/sub just call offset, the same limitation
applies here, as well.
I did not copy the whole explanation ("In particular, the resulting pointer may *not* be used to access a different allocated object [...]") because I'd consider that as being too repetitive. The documentation of add/sub already refers to the offset function, so people interested in the details can look it up, there.
But changing 'an object' to 'the same object' is a small change which improves clarity a lot.
Add missing lifetime fragment specifier to error message.
A very minor issue, `lifetime` was missing from the error list.
I left `literal` in the list, even though it is unstable. It looks like it may stabilize soon anyways.
Cleanup rustc/session
- improve allocations
- improve common patterns
- use `to_owned` when no string conversion is needed
- move `const`s up to improve readability
- whitespace & formatting improvements
second round of refactorings for universes
A second round of (what I believe to be) "no functional change" refactorings, taken from my universes branch.
r? @scalexm
Instead, we talk about:
- creating the "next" universe
- universes "extending" one another
- and `u1.can_name(u2)`, meaning that `u1` contains all names from `u2`

If the user's cookie/persistent storage setting forbid access to localStorage,
catch the exception and abort the access.
Currently, attempting to use the expand/contract links at the top of the page
for structs/consts/etc. fails due to an unhandled error while accessing
localStorage, if such access is forbidden, as the exception from the failed
access propagates all the way out, interrupting the expand/contract. Instead, I
would like to degrade gracefully; the access won't happen (the collapse/expand
state won't get persisted) but the actual expanding/contracting of the item
will go on to succeed.
Fixes#55079
update miri
This pulls in the changes in miri to actually enable validation. So, the rustc test suite will let us know if anything we cover regresses in that regard. :)

rustc: Allow targets to specify SIMD args are by-val
The upcoming SIMD support in the wasm target is unique from the other
platforms where it's either unconditionally available or not available,
there's no halfway where a subsection of the program can use it but no
other parts of the program can use it. In this world it's valid for wasm
SIMD args to always be passed by value and there's no need to pass them
by reference.
This commit adds a new custom target specification option
`simd_types_indirect` which defaults to `true`, but the wasm backend
disables this and sets it to `false`.
