From c74798d5cfbb7ae62e7e430e3b7097397faac848 Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Sat, 5 Nov 2011 11:52:44 +0000 Subject: Add an option to pad an uleb128 to MCObjectWriter and remove the uleb128 encoding from the DWARF asm printer. As a side effect we now print dwarf ulebs with .ascii directives. llvm-svn: 143809 --- llvm/lib/MC/MCObjectWriter.cpp | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'llvm/lib/MC/MCObjectWriter.cpp') diff --git a/llvm/lib/MC/MCObjectWriter.cpp b/llvm/lib/MC/MCObjectWriter.cpp index efe9f68ee22..18887397ab6 100644 --- a/llvm/lib/MC/MCObjectWriter.cpp +++ b/llvm/lib/MC/MCObjectWriter.cpp @@ -33,14 +33,22 @@ void MCObjectWriter::EncodeSLEB128(int64_t Value, raw_ostream &OS) { } /// Utility function to encode a ULEB128 value. -void MCObjectWriter::EncodeULEB128(uint64_t Value, raw_ostream &OS) { +void MCObjectWriter::EncodeULEB128(uint64_t Value, raw_ostream &OS, + unsigned Padding) { do { uint8_t Byte = Value & 0x7f; Value >>= 7; - if (Value != 0) + if (Value != 0 || Padding != 0) Byte |= 0x80; // Mark this byte that that more bytes will follow.
