From ba1ee2bab7a4cdc0975686e5099461c0b12c5345 Mon Sep 17 00:00:00 2001 From: Nikita Popov Date: Fri, 18 Oct 2024 09:23:24 +0200 Subject: [PATCH] [APInt] Enable APInt ctor assertion by default (#112670) This enables the assertion introduced in https://github.com/llvm/llvm-project/pull/106524, which checks that the value passed to the APInt constructor is indeed a valid N-bit signed or unsigned integer. Places that previously violated the assertion were updated in advance, e.g. in https://github.com/llvm/llvm-project/pull/80309. It is possible to opt-out of the check and restore the previous behavior by setting implicitTrunc=true. --- llvm/include/llvm/ADT/APInt.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/llvm/include/llvm/ADT/APInt.h b/llvm/include/llvm/ADT/APInt.h index 63a138527b32e1..953b2a27b71526 100644 --- a/llvm/include/llvm/ADT/APInt.h +++ b/llvm/include/llvm/ADT/APInt.h @@ -109,7 +109,7 @@ class [[nodiscard]] APInt { /// \param implicitTrunc allow implicit truncation of non-zero/sign bits of /// val beyond the range of numBits APInt(unsigned numBits, uint64_t val, bool isSigned = false, - bool implicitTrunc = true) + bool implicitTrunc = false) : BitWidth(numBits) { if (!implicitTrunc) { if (isSigned) {
