This prevents codegenning unnecessary double-traps in some situations.

This commit has some changes to allow users to enable emutls: 1. add `-Zhas-thread-local` flag to specify that std uses `#[thread_local]` instead of pthread key. 2. when using emutls, decorate symbol names to find thread local symbol correctly. 3. change `-Zforce-emulated-tls` to `-Ztls-model=emulated` to explicitly specify whether to generate emutls. 2023-12-01T21:45:18+00:00 bors bors@rust-lang.org 2023-12-01T21:45:18+00:00 urn:sha1:8c2b57721728233e074db69d93517614de338055 Restore `#![no_builtins]` crates participation in LTO. After #113716, we can make `#![no_builtins]` crates participate in LTO again. `#![no_builtins]` with LTO does not result in undefined references to the error. I believe this type of issue won't happen again. Fixes #72140. Fixes #112245. Fixes #110606. Fixes #105734. Fixes #96486. Fixes #108853. Fixes #108893. Fixes #78744. Fixes #91158. Fixes https://github.com/rust-lang/cargo/issues/10118. Fixes https://github.com/rust-lang/compiler-builtins/issues/347. The `nightly-2023-07-20` version does not always reproduce problems due to changes in compiler-builtins, core, and user code. That's why this issue recurs and disappears. Some issues were not tested due to the difficulty of reproducing them. r? pnkfelix cc `@bjorn3` `@japaric` `@alexcrichton` `@Amanieu` 2023-11-27T21:54:03+00:00 bors bors@rust-lang.org 2023-11-27T21:54:03+00:00 urn:sha1:49b3924bd4a34d3cf9c37b74120fba78d9712ab8 Update the minimum external LLVM to 16.
