From 3f22cc1df64a6dd6a3ecc5e7e261f15af083f806 Mon Sep 17 00:00:00 2001 From: David Majnemer Date: Wed, 25 Sep 2013 10:47:21 +0000 Subject: MC: Add support for treating $ as a reference to the PC The binutils assembler supports a mode called DOLLAR_DOT which treats the dollar sign token as a reference to the current program counter if the dollar sign doesn't precede a constant or identifier. This commit adds a new MCAsmInfo flag stating whether or not a given target supports this interpretation of the dollar sign token; by default, this flag is not enabled. Further, enable this flag for PPC. The system assembler for AIX and binutils both support using the dollar sign in this manner. This fixes PR17353. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191368 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/MC/MCAsmInfo.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'include/llvm/MC') diff --git a/include/llvm/MC/MCAsmInfo.h b/include/llvm/MC/MCAsmInfo.h index f5acd17..3734d7e 100644 --- a/include/llvm/MC/MCAsmInfo.h +++ b/include/llvm/MC/MCAsmInfo.h @@ -93,6 +93,10 @@ namespace llvm { /// this value.
