From 9e6d2da83dcc7fe58c0352d61d20b42f09182c63 Mon Sep 17 00:00:00 2001 From: bjorn3 <17426603+bjorn3@users.noreply.github.com> Date: Sun, 3 Nov 2024 18:26:01 +0000 Subject: Reduce dependence on the target name The target name can be anything with custom target specs. Matching on fields inside the target spec is much more robust than matching on the target name. --- compiler/rustc_codegen_llvm/src/back/write.rs | 29 +++++++++------------------ 1 file changed, 9 insertions(+), 20 deletions(-) (limited to 'compiler/rustc_codegen_llvm/src/back/write.rs') diff --git a/compiler/rustc_codegen_llvm/src/back/write.rs b/compiler/rustc_codegen_llvm/src/back/write.rs index 647e9e13fbc..a65ae4df1e3 100644 --- a/compiler/rustc_codegen_llvm/src/back/write.rs +++ b/compiler/rustc_codegen_llvm/src/back/write.rs @@ -945,23 +945,10 @@ fn create_section_with_flags_asm(section_name: &str, section_flags: &str, data: asm } -fn target_is_apple(cgcx: &CodegenContext) -> bool { - let triple = cgcx.opts.target_triple.tuple(); - triple.contains("-ios") - || triple.contains("-darwin") - || triple.contains("-tvos") - || triple.contains("-watchos") - || triple.contains("-visionos") -} - -fn target_is_aix(cgcx: &CodegenContext) -> bool { - cgcx.opts.target_triple.tuple().contains("-aix") -} - pub(crate) fn bitcode_section_name(cgcx: &CodegenContext) -> &'static CStr { - if target_is_apple(cgcx) { + if cgcx.target_is_like_osx { c"__LLVM,__bitcode" - } else if target_is_aix(cgcx) { + } else if cgcx.target_is_like_aix { c".ipa" } else { c".llvmbc" @@ -1028,10 +1015,12 @@ unsafe fn embed_bitcode( // Unfortunately, LLVM provides no way to set custom section flags.
