From 7a16288157efc5fb85fbe3b8b4c37071da7609a6 Mon Sep 17 00:00:00 2001 From: Jeffrey Yasskin Date: Mon, 18 Jul 2011 21:45:40 +0000 Subject: Add APInt(numBits, ArrayRef bigVal) constructor to prevent future ambiguity errors like the one corrected by r135261. Migrate all LLVM callers of the old constructor to the new one. llvm-svn: 135431 --- llvm/lib/Support/APInt.cpp | 20 ++++++++++++++------ 1 file changed, 14 insertions(+), 6 deletions(-) (limited to 'llvm/lib/Support/APInt.cpp') diff --git a/llvm/lib/Support/APInt.cpp b/llvm/lib/Support/APInt.cpp index 76265d4..0b25360 100644 --- a/llvm/lib/Support/APInt.cpp +++ b/llvm/lib/Support/APInt.cpp @@ -83,25 +83,33 @@ void APInt::initSlowCase(const APInt& that) { memcpy(pVal, that.pVal, getNumWords() * APINT_WORD_SIZE); } - -APInt::APInt(unsigned numBits, unsigned numWords, const uint64_t bigVal[]) - : BitWidth(numBits), VAL(0) { +void APInt::initFromArray(ArrayRef bigVal) { assert(BitWidth && "Bitwidth too small"); - assert(bigVal && "Null pointer detected!"); + assert(bigVal.data() && "Null pointer detected!"); if (isSingleWord()) VAL = bigVal[0]; else { // Get memory, cleared to 0 pVal = getClearedMemory(getNumWords()); // Calculate the number of words to copy - unsigned words = std::min(numWords, getNumWords()); + unsigned words = std::min(bigVal.size(), getNumWords()); // Copy the words from bigVal to pVal - memcpy(pVal, bigVal, words * APINT_WORD_SIZE); + memcpy(pVal, bigVal.data(), words * APINT_WORD_SIZE); } // Make sure unused high bits are cleared clearUnusedBits(); } +APInt::APInt(unsigned numBits, ArrayRef bigVal) + : BitWidth(numBits), VAL(0) { + initFromArray(bigVal); +} + +APInt::APInt(unsigned numBits, unsigned numWords, const uint64_t bigVal[]) + : BitWidth(numBits), VAL(0) { + initFromArray(makeArrayRef(bigVal, numWords)); +} + APInt::APInt(unsigned numbits, StringRef Str, uint8_t radix) : BitWidth(numbits), VAL(0) { assert(BitWidth && "Bitwidth too small"); -- cgit v1.1
