X86 new registers not being allocated
Hi all,
I have a bunch of new registers set up in X86RegisterInfo.td, the important
part being
def PR128 : RegisterClass<"X86", [i128],
128, (sequence "POI%u", 0, 7)>;
def VR128 : RegisterClass<"X86", [v4f32, v2f64, v16i8, v8i16, v4i32, v2i64],
128, (add PR128, FR32)>;

Registers for i128 data type not registered in X86
Hi,
I have a set of new registers for x86 which I defined in
X86RegisterInfo.td to be:
def POI0: X86Reg<"poi0", 0>;
def POI1: X86Reg<"poi1", 1>;
def POI2: X86Reg<"poi2", 2>;
def POI3: X86Reg<"poi3", 3>;
def POI4: X86Reg<"poi4", 4>;
def POI5: X86Reg<"poi5", 5>;
def POI6: X86Reg<"poi6",

LEAQ instruction path
Hi,
I've been trying to teach LLVM that pointers are 128-bit long, which
segfaults with some seemingly unrelated stacktrace when I try to take an
address of a variable. Since stack saving and loading seems to work fine, I
dare to assume the instruction causing problems there is leaq. Now I've
done a search for leaq of the entire LLVM codebase with no success and I'd
like to know which

Wrapper functions for standard library functions
Hi,
I would like to wrap some of the library functions such as malloc() into
for example:
malloc_wrapper(int size) {
malloc(size+4); //call the real malloc here
}
and have all uses of malloc replaced with malloc_wrapper. Is there a way to
do that?

New x86 instruction with opcode 0x0F 0x7A
Hi all,
I'm trying to simulate an extended x86 architecture on gem5 with several
new instructions. My hardware setup is done and now I'd like llvm to accept
the existence of the new instruction passed in inline assembly and output
the correct opcode and registers. I chose the two-byte opcode 0x0F 0x7A and
I would like the instruction to have the same operands and return values
as CVTPS2PI

Beginner question: extending pointer to 128 bits segfaults
Hi all,
I've been trying to extend pointer size of the X86 target to 128 bits. For
the prortype, I would like nothing more than the pointers being i128 type
with the same value as before. All I've done was changing the data layout
string to p:128:128 and when trying to run a basic program such as:
int a = 42;
int *p = &a;
it segfaults with the following stack trace:

CopyToReg node
Hi all,
I'm having some trouble with x86 generating some CopyToReg nodes with a
null 2nd operand. I've done an extensive search of the entire codebase and
found that all creation of CopyToReg nodes happens at SelectionDAG.h,
eventually, but my debug messages did not register a call to either of the
three getCopyToReg methods it provides. Is there any other place where
CopyToReg nodes get

Additional instructions created
Hi all,
I've got a few new registers and I've extended the pointer size to be 128
bits. For allocas, that is done by adding another SelectionDAG after
FrameIndex that extends it to 128 bits. That seems to work okay, except
that the final representation throws in additional instructions. For
example for a piece of code such as:
int a;
int* pointer = &a;
it returns
pushq %rbp

[PATCH libldm v3 0/2] Make libldm to parse and return volume GUID.
v2: wrap commit message, "PATCH libldm" prefix.
v3: correctly initialize and free GLib resources.
The result of this patch might be used by libguestfs to return drive
mappings for LDM volumes.
Note, that "show volume" ldmtool command already returns hint which
is a drive letter assigned by Windows to corresponding volume. But
it is not reliable source of information. More

Routing local generted packets with fwmark
Hi all,
I need to route local generated packages depending on which tcp or udp
service I need to use. To accomplish this I have configured two routing
tables:

32762: from all fwmark 0x2 lookup FirstLan
32763: from all fwmark 0x1 lookup SecondLan

AllocateTarget for ELF objects on Darwin
Hello everyone
I am linking the Clang libs into my executable for JIT compilation. In
order to enable debugging the jited code on OSX via the GDB JIT
Interface, I switched the format of the in-memory object files to ELF. I
thought this target triple should do:
Triple TT;
TT.setTriple(sys::getProcessTriple());
TT.setObjectFormat(llvm::Triple::ELF);
But Clang exits with an error:

DataMatrix barcode generator/reader
Hello,
I have an existing legacy app written in .NET that will be rewritten
with Rails. One of the key components of the App is to generate and
read datamatrix barcodes from a PDF. I''ve looked online and message
posts but haven''t see anything worthwhile for reading / generting
datamatrix barcodes. Any recommendations for this?

How can I render a template outside of a controller in Rails 3?
Hi All,
I can''t seem to render a template outside of a controller in my Rails 3
application. The googling I''ve done has been helpful, and I eventually found
some useful info at
http://www.swombat.com/rails-rendering-templates-outside-of-a-contro.
However, this seems to be broken in Rails 3. Does anyone have any ideas how
I can fix this method or perhaps know of a better
