[LLVMdev] Loop localize global variables
Hi Sundeep,
I am also interested in the load-store lifting transformation.
For static globals as-in your example, the transformation in general
would rely on a better static global aliasing information that is
currently in review http://reviews.llvm.org/D10059
For non-static globals, one problem with loop-based analysis alone is
that in a popular embedded benchmark suite, you get serious gains

[LLVMdev] Floating point ordered and unordered comparisons
Hi All,
I noticed LLVM target independent side is converting an ordered less than
"setolt" into unordered greater than "setuge" operation. There are no
target hooks to control going from the ordered mode into unordered.
I am trying to figure out the best way to support unordered operation on
Hexagon. We don't have a single instruction to do unordered operation. So

Recent -Os code size regressions
Hello LLVM,
Does the community have bots or humans tracking code size for -Os
builds? I've noticed troubling regressions lately. Sometime near Nov
5, the EEMBC bitmnp01 benchmark grew by 25% for ARMv7m and 35% for
i586. That's ghastly. This week, the EEMBC matrix01 workload grew by
5% for ARMv7m and 3% for i586.
Regards,
-steve

[LLVMdev] Post increment and register pressure
Hi all,
I am analyzing auto inc/dec optimization on ARM. On some loops, I noticed
aggressive post increment is resulting in poor code due to increased
register pressure.
I was wondering if there is a way to estimate register pressure during DAG
Combiner. I am trying to come up with some heuristic based on # of DAG
nodes, # of live ins and live outs, # of machine registers etc. Any
suggestions?

[LLVMdev] LLVM / CLANG Test Infrastructure Question
Hi All,
I am working on a bug in clang. I already have a fix for it and I am going
through the "LLVM Testing Infrastructure Guide" to make sure I haven't
broken anything else. I have few questions regarding the test suite
infrastructure that I hope someone can answer.

Recent -Os code size regressions
Maybe adjust this to be different for –Os, -Oz than for –O2?

[LLVMdev] Proposal: AArch64/ARM64 merge from EuroLLVM
Hi folks,
As Tim pointed out, we recently had the opportunity to collect 64-bit benchmark performance data for GCC 4.9, AArch64 and ARM64 compilers on a real hardware. It is a cortex-a53 device. Due to proprietary reasons we cannot share the full hardware configuration.
The preliminary results were shared at the hackers lab at EuroLLVM yesterday. For those who could not make it, below is

[LLVMdev] Contributing the Apple ARM64 compiler backend
Hi all,
Firstly thanks so much to Apple for open sourcing this and Tim for going
through the effort of committing it!
Along with Bradley I've been looking at this today from a perspective of
working out how best to get this merge completed. The one sentence summary
is "I think we should use ARM64 as a base".
My view on the backends is that the ARM64 backend is more performant but

[LLVMdev] Target backend not converting char* to struct properly.
I'm having trouble getting my backend to properly treat the situation where
a char* is converted into a struct, i.e. something like:
char* pointer_representation = ...;
MyStruct* my_struct = (MyStruct*) pointer_representation;
my_struct->an_int_field = 5;
When this occurs, LLVM seems to fold the struct and char* into one assembly
'object', which is perfectly fine. However, it also

HI James,
Thanks for your reply and hints on what can be done for the Aarch64 backend
optimization for llvm
We have SPEC license and v8 hardware. So I will start looking into it
