This commit adjusts the changes made in 159733. A wasi-libc bug was discovered in 160828 which is present in certain situations which means that the changes in 159733 expose this bug. The purpose of this PR is to get wasip1/wasip2 targets fixed again while preserving a working implementation for wasip3. This upstream bug is already fixed in wasi-libc meaning that this PR won't be necessary once wasi-sdk-34 is published and used in rust-lang/rust. Until that time, however, this effectively reverts 159733 for wasip1/wasip2. The wasip3 target is Tier 3 still and requires wasi-sdk-34 anyway which is why that's left unchanged. Closes 160828

the previous version, v0.5.0 (from 2018), does not include a Cargo lockfile which makes the test brittle as bugs and unintentional breaking changes in any new release of a dependency can make the test fail the newly chosen version, v0.7.7, includes a Cargo lockfile

This is currently not really implemented, but partial support for it is added in various places across the tree. This is a patch extracted from the wider set of work to make review easier, which wires up: * Unstable flag in rustc * Bootstrap flag to enable using wasm-proc-macros (this needs an extra std compilation, wiring into compiletest) * Partial compiletest support for the flag (mostly just CLI side of things)

Do not pass `-no-pie` on Windows The warning can be seen with a simple example: ``` ❯ cargo new /tmp/hello -q ❯ cargo rustc --target x86_64-pc-windows-gnullvm -q -- -C target-feature=+crt-static warning: linker stderr: clang: argument unused during compilation: '-no-pie' [-Wunused-command-line-argument] | = note: `#[warn(linker_messages)]` on by default ```

…oboet Arc: Remove unnecessary fmt::Display use for overflow assertion - [x] I did not use an LLM to create a change in this PR. - [ ] I used an LLM to create a change in this PR, and I have explained below how it was used. This PR removes unnecessary `fmt::Display` generated assembly because of use of formatting in the overflow check assertion(`assert!(n <= MAX_REFCOUNT, "{}", INTERNAL_OVERFLOW_ERROR);`). This reduces generated x64 assembly for counter increment(simplified) from: ```asm increase_counter: test rdi, rdi js .LBB1_2 inc rdi mov rax, rdi ret .LBB1_2: sub rsp, 24 lea rax, [rip + .Lanon.642d46026bcfa00bfed8baf8cdbf502d.2] mov qword ptr [rsp + 8], rax lea rax, [rip + <&str as core[4e7ceada952a6ea0]::fmt::Display>::fmt] mov qword ptr [rsp + 16], rax lea rdi, [rip + .Lanon.642d46026bcfa00bfed8baf8cdbf502d.0] lea rdx, [rip + .Lanon.642d46026bcfa00bfed8baf8cdbf502d.4] lea rsi, [rsp + 8] call qword ptr [rip + core[4e7ceada952a6ea0]::panicking::panic_fmt@GOTPCREL] .Lanon.642d46026bcfa00bfed8baf8cdbf502d.0: .asciz "\300" .Lanon.642d46026bcfa00bfed8baf8cdbf502d.1: .ascii "Arc counter overflow" ``` To: ```asm increase_counter: test rdi, rdi js .LBB0_2 inc rdi mov rax, rdi ret .LBB0_2: push rax lea rdi, [rip + .Lanon.642d46026bcfa00bfed8baf8cdbf502d.0] lea rdx, [rip + .Lanon.642d46026bcfa00bfed8baf8cdbf502d.2] mov esi, 41 call qword ptr [rip + core[4e7ceada952a6ea0]::panicking::panic_fmt@GOTPCREL] .Lanon.642d46026bcfa00bfed8baf8cdbf502d.0: .ascii "Arc counter overflow" ``` Godbolt link: https://godbolt.org/z/3qjxooYWM I expect bors to report a binary size reduction for all programs using Arc. There might also be performance improvements as a byproduct of CPU cache hit increase.

Miri: give the incremental session a chance to finish This helps with rust-lang/miri#5013. Reruns still aren't as fast as I'd like, but using nextest to run libcore tests shows a big difference: ``` before: Nextest run ID 56b7b355-6225-4083-96e3-aeeabbe80523 with nextest profile: default-miri Starting 10 tests across 2 binaries (2760 tests skipped) PASS [ 31.264s] coretests::coretests any::any_downcast_mut PASS [ 31.287s] coretests::coretests any::distinct_type_names PASS [ 32.747s] coretests::coretests iter::traits::iterator::test_any PASS [ 32.758s] coretests::coretests any::any_owning PASS [ 32.864s] coretests::coretests any::dyn_type_name PASS [ 32.973s] coretests::coretests any::any_downcast_ref PASS [ 33.139s] coretests::coretests any::any_unsized PASS [ 33.719s] coretests::coretests any::any_referenced PASS [ 35.786s] coretests::coretests any::any_fixed_vec PASS [ 38.951s] coretests::coretests num::dec2flt::parse::many_digits ──────────── Summary [ 38.955s] 10 tests run: 10 passed, 2760 skipped after: Nextest run ID af603971-e41e-466d-8469-0425057fa325 with nextest profile: default-miri Starting 10 tests across 2 binaries (2761 tests skipped) PASS [ 15.063s] coretests::coretests any::any_unsized PASS [ 15.176s] coretests::coretests any::distinct_type_names PASS [ 15.200s] coretests::coretests any::any_referenced PASS [ 15.550s] coretests::coretests iter::traits::iterator::test_any PASS [ 15.993s] coretests::coretests any::any_fixed_vec PASS [ 17.506s] coretests::coretests num::dec2flt::parse::many_digits PASS [ 17.902s] coretests::coretests any::any_downcast_ref PASS [ 18.188s] coretests::coretests any::any_owning PASS [ 19.270s] coretests::coretests any::dyn_type_name PASS [ 19.702s] coretests::coretests any::any_downcast_mut ──────────── Summary [ 19.705s] 10 tests run: 10 passed, 2761 skipped ``` It still seems to spend at least 10s building the crate before Miri even begins running, no idea what it is doing in that time. But it's 15s less than before so that's good. :)

…, r=bjorn3,jieyouxu Add -Zwasm-proc-macros flag This is currently not really implemented, but partial support for it is added in various places across the tree. This is a patch extracted from the wider set of work to make review easier, which wires up: * Unstable flag in rustc * Bootstrap flag to enable using wasm-proc-macros (this needs an extra std compilation, wiring into compiletest) * Partial compiletest support for the flag (mostly just CLI side of things) * I suspect this will not work across all platforms but based on success with the full patch it should be enough for Linux, I think. I'd rather get them working on at least one platform and then iterate from there, unless we have clear ideas for improvements now. cc rust-lang#160389 (tracking issue) cc rust-lang#157590 (more complete implementation) r? @bjorn3
