From 0c58bc64a4bd40561ae044527c4e1f8190f435f7 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. llvm-svn: 191368 --- llvm/lib/Target/PowerPC/MCTargetDesc/PPCMCAsmInfo.cpp | 2 ++ 1 file changed, 2 insertions(+) (limited to 'llvm/lib/Target/PowerPC/MCTargetDesc/PPCMCAsmInfo.cpp') diff --git a/llvm/lib/Target/PowerPC/MCTargetDesc/PPCMCAsmInfo.cpp b/llvm/lib/Target/PowerPC/MCTargetDesc/PPCMCAsmInfo.cpp index 1f3e5b49a64..91578a9b504 100644 --- a/llvm/lib/Target/PowerPC/MCTargetDesc/PPCMCAsmInfo.cpp +++ b/llvm/lib/Target/PowerPC/MCTargetDesc/PPCMCAsmInfo.cpp @@ -54,6 +54,8 @@ PPCLinuxMCAsmInfo::PPCLinuxMCAsmInfo(bool is64Bit) { // Debug Information SupportsDebugInformation = true; + DollarIsPC = true; + // Set up DWARF directives HasLEB128 = true; // Target asm supports leb128 directives (little-endian) MinInstAlignment = 4; -- cgit v1.2.3
