2020-03-13Auto merge of #67502 - Mark-Simulacrum:opt-catch, r=Mark-Simulacrumbors-1/+0
Optimize catch_unwind to match C++ try/catch This refactors the implementation of catching unwinds to allow LLVM to inline the "try" closure directly into the happy path, avoiding indirection. This means that the catch_unwind implementation is (after this PR) zero-cost unless a panic is thrown. https://rust.godbolt.org/z/cZcUSB is an example of the current codegen in a simple case. Notably, the codegen is *exactly the same* if `-Cpanic=abort` is passed, which is clearly not great. This PR, on the other hand, generates the following assembly: ```asm # -Cpanic=unwind: push rbx mov ebx,0x2a call QWORD PTR [rip+0x1c53c] # <happy> mov eax,ebx pop rbx ret mov rdi,rax call QWORD PTR [rip+0x1c537] # cleanup function call call QWORD PTR [rip+0x1c539] # <unfortunate> mov ebx,0xd mov eax,ebx pop rbx ret # -Cpanic=abort: push rax call QWORD PTR [rip+0x20a1] # <happy> mov eax,0x2a pop rcx ret ``` Fixes #64224, and resolves #64222.

rustc, rustc_passes: reduce deps on rustc_expand Part of #65324. r? @petrochenkov
2019-10-27Always use consteval to codegen caller_location.Adam Perry-2/+0
2019-10-27Panicking infra uses &core::panic::Location.Adam Perry-9/+0
This allows us to remove `static_panic_msg` from the SSA<->LLVM boundary, along with its fat pointer representation for &str. Also changes the signature of PanicInfo::internal_contructor to avoid copying. Closes #65856.
2019-10-27Implement core::intrinsics::caller_location.Adam Perry-0/+4
Returns a `&core::panic::Location` corresponding to where it was called, also making `Location` a lang item.
2019-10-27rustc, rustc_passes: don't depend on syntax_expand.Mazdak Farrokhzad-1/+1
This is done by moving some data definitions to syntax::expand.
2019-10-21Use `Symbol` for codegen unit names.Nicholas Nethercote-2/+2
This is a straightforward replacement except for two places where we have to convert to `LocalInternedString` to get a stable sort.

2019-10-10Auto merge of #59546 - sfanxiang:interminable-ub, r=nagisabors-0/+1
Add llvm.sideeffect to potential infinite loops and recursions LLVM assumes that a thread will eventually cause side effect. This is not true in Rust if a loop or recursion does nothing in its body, causing undefined behavior even in common cases like `loop {}`. Inserting llvm.sideeffect fixes the undefined behavior. As a micro-optimization, only insert llvm.sideeffect when jumping back in blocks or calling a function. A patch for LLVM is expected to allow empty non-terminate code by default and fix this issue from LLVM side. https://github.com/rust-lang/rust/issues/28728 **UPDATE:** [Mentoring instructions here](https://github.com/rust-lang/rust/pull/59546#issuecomment-515072429) to unstall this PR

2019-09-26Rollup merge of #64772 - Mark-Simulacrum:no-tyctxt-tx, r=eddybMazdak Farrokhzad-1/+7
Remove tx_to_llvm_workers from TyCtxt This can be kept within the codegen backend crates entirely -- there's no reason for us to create it outside and attempt to hold it in the (global) context. Changes here aren't really too easily reviewable I suspect -- not sure if they can be cleaned up by splitting into more commits though, it's just hard to reason about `Box<Any>` in general. If there are thoughts though I'd be happy to hear them. The primary goal of this PR is to get rid of the field on `rustc_interface::Queries`.
