Why do constant SD nodes not set the IROrder?
Specifically I would like to understand why ConstantSDNode and ConstantFPSDNode do not set the IR ordering like most other SDNode-s. These constant SD nodes also previously did not set the debugloc, but that got enabled (here: http://llvm.org/viewvc/llvm-project?view=revision&revision=237237).
These constant SD nodes hard-code the order to 0. Is this intentional, or just something that has

Matching ConstantFPSDNode tablegen
I'm trying to match a ConstantFPSDNode == 0 in dag pattern for tablegen but
am having some issues.
So LLVM doesn't seem to accept a floating point constant literal match like:
%v = call <4 x float> @foo(i32 15, float %s, float 0.0, <8 x i32> %rsrc, <4
x i32> %samp, i1 0, i32 0, i32 0)

[LLVMdev] Query Regarding instruction ordering of passive nodes
Hi All,
I'm trying to compile the attached code(gdb11531.c) with latest clang with -O0 on ARM.
Clang seems to be reordering the instructions in case of constant nodes(for ARM) even when O0 is specified resulting in few wrong information when debugging through GDB.
I had few queries,would be great if someone could clarify the same -
In the given assembly code, the instructions where constant

Question about identifier name mangling in LLVM manual
The Identifiers section in the LLVM language manual states:
"The "\01" prefix can be used on global variables to suppress mangling."
Is this for global variables only, or global values in general, such as functions also? In implementation LLVM seems to have this behavior of suppressing mangling even for functions and aliases.
Thanks,
Gautam

In your case, Eric's suggestion was effectively "start implementing fast-isel". Which is not a bad idea if you want to reduce compile

Xen in a Box Proposal
Hi,
Regarding my gsoc proposal (xen in a box), I have developed a set of
scripts to create a custom CentOS ISO which delivers Xen 4.4 stack on
CentOS 6.6 with libvirt and fully bridge network settings. I have used xen
scripts for networking settings.
Waiting for feedback.

[LLVMdev] [PATCH] Propagate DAG node ordering during legalization and instruction selection
Hi,
We've recently encountered a problem in our compiler where the line number in debug info jumps back and force even at O0. This is caused by DAG node ordering not being properly kept during legalization and instruction selection. There are still uncaught cases after applying the patch mentioned here.
So I have decided to implement the approach suggested by Andy as below. i.e. maintain the

it worked, I was able to build all the packages for xenserver on CentOS 6.6
final version.
Here is the package list:

I was wondering what packages would be necessary to use Xen with xapi, I
already have xen with xl installed. Could we have a package like

[LLVMdev] Proposal: Add a target lowering hook to state that target supports floating point exception behavior.
Hello All,
the patch below adds a target lowering hook to state that the target supports (or not) floating point exception behavior. The patch is small and contains one possible use for the hook (folding potentially exception raising fp operations).
Any comments?
Thanks

I assume you meant to ask for ports that *don’t* support floating point exceptions. To my knowledge, neither R600 nor NVPTX support floating point exceptions.

[LLVMdev] Bikeshedding a name for new directive: CHECK-LABEL vs. CHECK-BOUNDARY vs. something else.
Hi,
I would like to add a new directive to FileCheck called CHECK-FOO
(where FOO is a name under discussion right now) which is used to
improve error messages. The idea is that you would use CHECK-FOO on
any line that contains a unique identifier (typically labels, function
definitions, etc.) that is guaranteed to only occur once in the file;
FileCheck will then conceptually break the break the
