Forward `TEST_SAMPLE_INTRINSICS_PERCENTAGE`
Add intrinsics for the new AMX target features
compiler-builtins subtree update Subtree update of `compiler-builtins` to 8a3e35b. Created using https://github.com/rust-lang/josh-sync. r? `@ghost`
Update to LLVM 21.1.8 Fixes rust-lang/rust#149522.
Remove Expressions (and just use a Vec) in coerce Let's see if this has much of a perf impact - would be nice to clean this up a bit r? ghost
Prefer remapping the relative `library/` and `compiler/` directories This is done to avoid leaking the relative paths to the standard library after the overall of filenames in rust-lang/rust#149709. Noted that the paths were already leaking before, but to a lesser extent since most (but not all) the paths embedded in the distributed `rlib` were absolute. In general Cargo compiles workspace members with relative paths, so it's better anyway to remap the relative path. In addition to our tests I have manually confirmed that it also works as expected for the printed diagnostics paths. cf. https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/remapping.20of.20the.20standard.20library/near/564093571
Perf regression fix The only thing changed from the previous PR is that I removed `output_is_inhabited` from hot path, and hide it behind condition, so now it will compute it less frequent follow up on rust-lang/rust#149664
Better closure requirement propagation. Fixes rust-lang/rust#148289 Fixes rust-lang/rust#104477 Should unblock rust-lang/rust#148187 When propagating closure requirements we: - no longer try to find a post dominiting region for the list of non-local lower bounds of `longer_fr`. - we filter the list of `longer_fr-: shorter_fr+` to only these constraints between external regions which are required regardless. If no such constraint exists, we fall back to propagating all of them. See the [FCP](rust-lang/rust#148329 (comment)) for more information. r? `@lcnr`
Fix trailing newline in JUnit formatter `write_message()` expects messages to contain no newlines. Fixes rust-lang/rust#149436
…,saethlin Replace Rvalue::NullaryOp by a variant in mir::Operand. Based on rust-lang/rust#148151 This PR fully removes the MIR `Rvalue::NullaryOp`. After rust-lang/rust#148151, it was only useful for runtime checks like `ub_checks`, `contract_checks` and `overflow_checks`. These are "runtime" checks, boolean constants that may only be `true` in codegen. It depends on a rustc flag passed to codegen, so we need to represent those flags cross-crate. This PR replaces those runtime checks by special variants in MIR `ConstValue`. This allows code that expects constants to manipulate those as such, even if we may not always be able to evaluate them to actual scalars.
stdarch subtree update Subtree update of `stdarch` to rust-lang/stdarch@6111906. Created using https://github.com/rust-lang/josh-sync. r? `@sayantn` My first josh sync, it lgtm, but let me know if I missed something. I'm especially looking forward to the amd GPU module, which we want to use for the offload project.

…e-numbers, r=yotamofek Fix copy code example with line numbers Fixes rust-lang/rust#150339. Since the line numbers are now included in the actual highlighted code, we need to filter them out when we "copy" the code. r? `@yotamofek`
JumpThreading: compute place and value indices on-demand Profiling JumpThreading reveals that a large part of the runtime happens constructing the place and value `Map`. This is unfortunate, as jump-threading may end up not even doing anything. The cause for this large up-front cost is following: `Map` attempts to create a `PlaceIndex` for each place that *may* hold a relevant value. This means all places that appear in MIR, but also all places whose value is accessed by a projection of a copy of a larger place. This PR refactors the creation of `Map` to happen on-demand: place and value indices are created when threading computation happens. The up-front mode is still relevant for DataflowConstProp, so is not touched.
…Simulacrum Add `MaybeDangling` to `core` This is the library part of adding `MaybeDangling`. Note that it doesn't actually do anything described in its docs (yet), I'll make a separate PR for that. Tracking issue: rust-lang/rust#118166. r? libs cc `@RalfJung`

…emove unsafe from usages" We can't drop the `unsafe` here because it is required at the `libm` MSRV. Instead, we will need to `allow` the lint. This reverts commit 96ac362.
