From 92b50800f6ebd5354e8e2e8b876855265d10625c Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Mon, 5 Feb 2007 23:51:43 +0000 Subject: [PATCH] Although targets are not required to support integers > 64bits, TargetData must in order for backends that do want to support large integer types to be able to function. Consequently, don't assert if the bitwidth > 64 bits when computing the size and alignment. Instead, compute the size by rounding up to the next even number of bytes for the size. Compute the alignment as the same as the LongABIAlignment. These provide reasonable defaults that the target can override. llvm-svn: 33943 --- llvm/lib/Target/TargetData.cpp | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/llvm/lib/Target/TargetData.cpp b/llvm/lib/Target/TargetData.cpp index 559f4d049040..aa32530d4b53 100644 --- a/llvm/lib/Target/TargetData.cpp +++ b/llvm/lib/Target/TargetData.cpp @@ -295,8 +295,10 @@ static inline void getTypeInfoABI(const Type *Ty, const TargetData *TD, Size = 4; Alignment = TD->getIntABIAlignment(); } else if (BitWidth <= 64) { Size = 8; Alignment = TD->getLongABIAlignment(); - } else - assert(0 && "Integer types > 64 bits not supported."); + } else { + Size = ((BitWidth + 7) / 8) & ~1; + Alignment = TD->getLongABIAlignment(); + } return; } case Type::VoidTyID: Size = 1; Alignment = TD->getByteABIAlignment(); return;
