Hi, I am encountering a problem that I do not know how to debug. I would greatly appreciate any guidance on this issue. On Windows when I run Lua test cases from JITed code I am getting following error: Unhandled exception at 0x00007FFCEEEAC500 (ntdll.dll) in lua.exe: 0xC0000028: An invalid or unaligned stack was encountered during an unwind operation. This is happening when the Lua code is

Hello. I generated in the back end by hand (in C++ code, not with TableGen) some fancy assembly code using Inline ASM expressions and if I use 2 functions in my source code (but NOT just 1 function; I will not present the functions, but each requires me to generate an Inline ASM expression) I get this error at compilation (at scheduling): BB#0: derived from LLVM BB %entry

With the patch alone, the void* overload of addGarbageObject() was being used by MDNode::getTemporary(), so I had to cast the object as an MDNode*: diff --git a/lib/IR/Metadata.cpp b/lib/IR/Metadata.cpp

There aren't any leaks to be had there, since they're allocated in a custom allocator. They're

Hi there, I am starting a new thread to try and solve a problem I am having will slow network throughput to the XEN host (not to a domU). I have confirmed my problem occurs with PVOPS ''xen/master'' kernel as well using http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.31.6-pvops-dom0-xen-master-x86_64 as the .config. It also occurs with a forward ported xenified kernel

LTOCodeGenerator::addModule (which is wrapped by lto_codegen_add_module) takes an LTOModule as an argument and links the latter's llvm::Module into its own. It does not change the latter's llvm::Module. The lto_module_dispose API call destroys an LTOModule. This frees the LTOModule's llvm::Module, but also invalidates strings returned by, e.g., lto_module_get_symbol_name. I propose

Greetings, I had a quick question about lower memory usage by memdisk. I've read through the mail archives and found a couple of posted questions but unfortunately no answers. I know the documentation states: "MEMDISK simulates a disk by claiming a chunk of high memory for the disk and a (very small - 2K typical) chunk of low (DOS) memory for the driver itself, then hooking the INT 13h
