From bf387df302096597626293d01ea06fd1ccdeeac1 Mon Sep 17 00:00:00 2001 From: Jim Grosbach Date: Wed, 8 Aug 2012 23:56:06 +0000 Subject: Move [SU]LEB128 encoding to a utility header. These functions are very generic. There's no reason for them to be tied to MCObjectWriter. llvm-svn: 161545 --- llvm/lib/MC/MCObjectWriter.cpp | 34 ---------------------------------- 1 file changed, 34 deletions(-) (limited to 'llvm/lib/MC/MCObjectWriter.cpp') diff --git a/llvm/lib/MC/MCObjectWriter.cpp b/llvm/lib/MC/MCObjectWriter.cpp index 030f24793c5..94d7cd6fd4f 100644 --- a/llvm/lib/MC/MCObjectWriter.cpp +++ b/llvm/lib/MC/MCObjectWriter.cpp @@ -17,40 +17,6 @@ using namespace llvm; MCObjectWriter::~MCObjectWriter() { } -/// Utility function to encode a SLEB128 value. -void MCObjectWriter::EncodeSLEB128(int64_t Value, raw_ostream &OS) { - bool More; - do { - uint8_t Byte = Value & 0x7f; - // NOTE: this assumes that this signed shift is an arithmetic right shift. - Value >>= 7; - More = !((((Value == 0 ) && ((Byte & 0x40) == 0)) || - ((Value == -1) && ((Byte & 0x40) != 0)))); - if (More) - Byte |= 0x80; // Mark this byte that that more bytes will follow. - OS << char(Byte); - } while (More); -} - -/// Utility function to encode a ULEB128 value. -void MCObjectWriter::EncodeULEB128(uint64_t Value, raw_ostream &OS, - unsigned Padding) { - do { - uint8_t Byte = Value & 0x7f; - Value >>= 7; - if (Value != 0 || Padding != 0) - Byte |= 0x80; // Mark this byte that that more bytes will follow. - OS << char(Byte); - } while (Value != 0); - - // Pad with 0x80 and emit a null byte at the end. - if (Padding != 0) { - for (; Padding != 1; --Padding) - OS << '\x80'; - OS << '\x00'; - } -} - bool MCObjectWriter::IsSymbolRefDifferenceFullyResolved(const MCAssembler &Asm, const MCSymbolRefExpr *A, -- cgit v1.2.3
