From 4160a54dc5751d08dd23c7e5b0dc6cbc0889ce32 Mon Sep 17 00:00:00 2001 From: Josh Stone Date: Thu, 26 Sep 2024 20:33:26 -0700 Subject: [PATCH] Use `&raw` in the compiler Like #130865 did for the standard library, we can use `&raw` in the compiler now that stage0 supports it. Also like the other issue, I did not make any doc or test changes at this time. --- compiler/rustc_codegen_llvm/src/back/archive.rs | 2 +- compiler/rustc_codegen_llvm/src/lib.rs | 4 ++-- compiler/rustc_codegen_llvm/src/llvm_util.rs | 2 +- compiler/rustc_data_structures/src/sync.rs | 2 +- compiler/rustc_middle/src/query/on_disk_cache.rs | 4 ++-- compiler/rustc_middle/src/ty/list.rs | 10 +++++----- compiler/stable_mir/src/compiler_interface.rs | 2 +- 7 files changed, 13 insertions(+), 13 deletions(-) diff --git a/compiler/rustc_codegen_llvm/src/back/archive.rs b/compiler/rustc_codegen_llvm/src/back/archive.rs index 1b4f6682af0..33a956e552f 100644 --- a/compiler/rustc_codegen_llvm/src/back/archive.rs +++ b/compiler/rustc_codegen_llvm/src/back/archive.rs @@ -123,7 +123,7 @@ fn get_llvm_object_symbols( llvm::LLVMRustGetSymbols( buf.as_ptr(), buf.len(), - std::ptr::addr_of_mut!(*state) as *mut c_void, + (&raw mut *state) as *mut c_void, callback, error_callback, ) diff --git a/compiler/rustc_codegen_llvm/src/lib.rs b/compiler/rustc_codegen_llvm/src/lib.rs index bdfc0f626f8..b85d28a2f1f 100644 --- a/compiler/rustc_codegen_llvm/src/lib.rs +++ b/compiler/rustc_codegen_llvm/src/lib.rs @@ -167,7 +167,7 @@ impl WriteBackendMethods for LlvmCodegenBackend { fn print_pass_timings(&self) { unsafe { let mut size = 0; - let cstr = llvm::LLVMRustPrintPassTimings(std::ptr::addr_of_mut!(size)); + let cstr = llvm::LLVMRustPrintPassTimings(&raw mut size); if cstr.is_null() { println!("failed to get pass timings"); } else { @@ -180,7 +180,7 @@ impl WriteBackendMethods for LlvmCodegenBackend { fn print_statistics(&self) { unsafe { let mut size = 0; - let cstr = llvm::LLVMRustPrintStatistics(std::ptr::addr_of_mut!(size)); + let cstr = llvm::LLVMRustPrintStatistics(&raw mut size); if cstr.is_null() { println!("failed to get pass stats"); } else { diff --git a/compiler/rustc_codegen_llvm/src/llvm_util.rs b/compiler/rustc_codegen_llvm/src/llvm_util.rs index 71fd7afb148..a2a5499597c 100644 --- a/compiler/rustc_codegen_llvm/src/llvm_util.rs +++ b/compiler/rustc_codegen_llvm/src/llvm_util.rs @@ -478,7 +478,7 @@ pub(crate) fn print(req: &PrintRequest, mut out: &mut String, sess: &Session) { &tm, cpu_cstring.as_ptr(), callback, - std::ptr::addr_of_mut!(out) as *mut c_void, + (&raw mut out) as *mut c_void, ); } } diff --git a/compiler/rustc_data_structures/src/sync.rs b/compiler/rustc_data_structures/src/sync.rs index 6df94bc0e94..a3491dbfec7 100644 --- a/compiler/rustc_data_structures/src/sync.rs +++ b/compiler/rustc_data_structures/src/sync.rs @@ -437,7 +437,7 @@ impl RwLock { #[inline(always)] pub fn leak(&self) -> &T { let guard = self.read(); - let ret = unsafe { &*std::ptr::addr_of!(*guard) }; + let ret = unsafe { &*(&raw const *guard) }; std::mem::forget(guard); ret } diff --git a/compiler/rustc_middle/src/query/on_disk_cache.rs b/compiler/rustc_middle/src/query/on_disk_cache.rs index 06c9ebc87b5..35a16684615 100644 --- a/compiler/rustc_middle/src/query/on_disk_cache.rs +++ b/compiler/rustc_middle/src/query/on_disk_cache.rs @@ -233,7 +233,7 @@ impl<'sess> OnDiskCache<'sess> { for (index, file) in files.iter().enumerate() { let index = SourceFileIndex(index as u32); - let file_ptr: *const SourceFile = std::ptr::addr_of!(**file); + let file_ptr: *const SourceFile = &raw const **file; file_to_file_index.insert(file_ptr, index); let source_file_id = EncodedSourceFileId::new(tcx, file); file_index_to_stable_id.insert(index, source_file_id); @@ -827,7 +827,7 @@ pub struct CacheEncoder<'a, 'tcx> { impl<'a, 'tcx> CacheEncoder<'a, 'tcx> { #[inline] fn source_file_index(&mut self, source_file: Lrc) -> SourceFileIndex { - self.file_to_file_index[&std::ptr::addr_of!(*source_file)] + self.file_to_file_index[&(&raw const *source_file)] } /// Encode something with additional information that allows to do some diff --git a/compiler/rustc_middle/src/ty/list.rs b/compiler/rustc_middle/src/ty/list.rs index ec9ca65dbda..ea07cd3a1b9 100644 --- a/compiler/rustc_middle/src/ty/list.rs +++ b/compiler/rustc_middle/src/ty/list.rs @@ -103,13 +103,13 @@ impl RawList { let mem = arena.dropless.alloc_raw(layout) as *mut RawList; unsafe { // Write the header - ptr::addr_of_mut!((*mem).skel.header).write(header); + (&raw mut (*mem).skel.header).write(header); // Write the length - ptr::addr_of_mut!((*mem).skel.len).write(slice.len()); + (&raw mut (*mem).skel.len).write(slice.len()); // Write the elements - ptr::addr_of_mut!((*mem).skel.data) + (&raw mut (*mem).skel.data) .cast::() .copy_from_nonoverlapping(slice.as_ptr(), slice.len()); @@ -160,7 +160,7 @@ macro_rules!
