From 343da2e255623080f61f93c3363a9a028bb62119 Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Wed, 11 Dec 2013 22:18:44 +0000 Subject: On ELF and COFF treat linker_private like private. The linkers on these systems don't have anything special to do with these symbols. Since the intent is for them to be absent from the final object, just treat them as private. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197080 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/MC/MCAsmInfo.h | 17 ++++++++++++----- 1 file changed, 12 insertions(+), 5 deletions(-) (limited to 'include') diff --git a/include/llvm/MC/MCAsmInfo.h b/include/llvm/MC/MCAsmInfo.h index f09428d28c..5bd42e90f5 100644 --- a/include/llvm/MC/MCAsmInfo.h +++ b/include/llvm/MC/MCAsmInfo.h @@ -124,10 +124,12 @@ namespace llvm { /// file. const char *PrivateGlobalPrefix; // Defaults to "L" - /// LinkerPrivateGlobalPrefix - This prefix is used for symbols that should - /// be passed through the assembler but be removed by the linker.
