From 71280b55a3406c7dd4215449bf4a3ab216e78ffd Mon Sep 17 00:00:00 2001 From: Ivan Krasin Date: Thu, 15 Sep 2011 23:13:00 +0000 Subject: use 64-bit types instead of off_t/size_t to avoid the issue when gold plugin is built with Large File Support (sizeof(off_t) == 64 on i686) and the rest of LLVM is built w/o Large File Support (sizeof(off_t) == 32 on i686) which corrupts the stack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139873 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Support/MemoryBuffer.cpp | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'lib/Support/MemoryBuffer.cpp') diff --git a/lib/Support/MemoryBuffer.cpp b/lib/Support/MemoryBuffer.cpp index d264be9ace..0771af5fee 100644 --- a/lib/Support/MemoryBuffer.cpp +++ b/lib/Support/MemoryBuffer.cpp @@ -275,16 +275,16 @@ static bool shouldUseMmap(int FD, error_code MemoryBuffer::getOpenFile(int FD, const char *Filename, OwningPtr &result, - size_t FileSize, size_t MapSize, - off_t Offset, + uint64_t FileSize, uint64_t MapSize, + int64_t Offset, bool RequiresNullTerminator) { static int PageSize = sys::Process::GetPageSize(); // Default is to map the full file. - if (MapSize == size_t(-1)) { + if (MapSize == uint64_t(-1)) { // If we don't know the file size, use fstat to find out. fstat on an open // file descriptor is cheaper than stat on a random path. - if (FileSize == size_t(-1)) { + if (FileSize == uint64_t(-1)) { struct stat FileInfo; // TODO: This should use fstat64 when available. if (fstat(FD, &FileInfo) == -1) { -- cgit v1.2.3-70-g09d2
