From c15a698f567356cea22e79686c2883f3557bae0b Mon Sep 17 00:00:00 2001 From: Trevor Gross Date: Fri, 21 Jun 2024 14:08:49 -0500 Subject: [PATCH] Rename the `asm-comments` compiler flag to `verbose-asm` Since this codegen flag now only controls LLVM-generated comments rather than all assembly comments, make the name more accurate (and also match Clang). --- compiler/rustc_codegen_llvm/src/back/owned_target_machine.rs | 4 ++-- compiler/rustc_codegen_llvm/src/back/write.rs | 4 ++-- compiler/rustc_codegen_llvm/src/llvm/ffi.rs | 2 +- compiler/rustc_interface/src/tests.rs | 2 +- compiler/rustc_llvm/llvm-wrapper/PassWrapper.cpp | 4 ++-- compiler/rustc_session/src/options.rs | 4 ++-- 6 files changed, 10 insertions(+), 10 deletions(-) diff --git a/compiler/rustc_codegen_llvm/src/back/owned_target_machine.rs b/compiler/rustc_codegen_llvm/src/back/owned_target_machine.rs index 28a88dd2efe..b72636a6224 100644 --- a/compiler/rustc_codegen_llvm/src/back/owned_target_machine.rs +++ b/compiler/rustc_codegen_llvm/src/back/owned_target_machine.rs @@ -32,7 +32,7 @@ impl OwnedTargetMachine { unique_section_names: bool, trap_unreachable: bool, singletree: bool, - asm_comments: bool, + verbose_asm: bool, emit_stack_size_section: bool, relax_elf_relocations: bool, use_init_array: bool, @@ -64,7 +64,7 @@ impl OwnedTargetMachine { unique_section_names, trap_unreachable, singletree, - asm_comments, + verbose_asm, emit_stack_size_section, relax_elf_relocations, use_init_array, diff --git a/compiler/rustc_codegen_llvm/src/back/write.rs b/compiler/rustc_codegen_llvm/src/back/write.rs index 5e481eb98f5..2fda19bf0c9 100644 --- a/compiler/rustc_codegen_llvm/src/back/write.rs +++ b/compiler/rustc_codegen_llvm/src/back/write.rs @@ -214,7 +214,7 @@ pub fn target_machine_factory( sess.opts.unstable_opts.trap_unreachable.unwrap_or(sess.target.trap_unreachable);
