From a70e3fca1a0e1df2fccacaed3ea0fb91510363ff Mon Sep 17 00:00:00 2001 From: Lang Hames Date: Tue, 11 Feb 2014 05:28:24 +0000 Subject: In RuntimeDyldImpl::emitSection, make Allocate (section size to be allocated) a uintptr_t. An unsigned could overflow for large sections. No test case - anything big enough to overflow an unsigned is going to take an appreciable time to zero when the test passes. The choice of uintptr_t was made to match the RTDyldMemoryManager APIs, but these should probably be hardcoded to uint64_ts: It is legitimate to JIT for 64-bit targets from a 32-bit host/compiler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201127 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/ExecutionEngine/RuntimeDyld/RuntimeDyld.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/ExecutionEngine/RuntimeDyld/RuntimeDyld.cpp') diff --git a/lib/ExecutionEngine/RuntimeDyld/RuntimeDyld.cpp b/lib/ExecutionEngine/RuntimeDyld/RuntimeDyld.cpp index b858965b5c..7a1c4d7690 100644 --- a/lib/ExecutionEngine/RuntimeDyld/RuntimeDyld.cpp +++ b/lib/ExecutionEngine/RuntimeDyld/RuntimeDyld.cpp @@ -298,7 +298,7 @@ unsigned RuntimeDyldImpl::emitSection(ObjectImage &Obj, if (Name == ".eh_frame") PaddingSize = 4; - unsigned Allocate; + uintptr_t Allocate; unsigned SectionID = Sections.size(); uint8_t *Addr; const char *pData = 0; -- cgit v1.2.3
