[LLVMdev] [llvm-commits] [PATCH] BasicBlock Autovectorization Pass
Tobias, et al.,
Attached is the my autovectorization pass. I've fixed a bug that appears
when using -bb-vectorize-aligned-only, fixed some 80-col violations,
etc., and at least on x86_64, all test cases pass except for a few; and
all of these failures look like instruction-selection bugs. For example:

an error: error in

Tobias,
I've attached the latest version of my autovectorization patch. I was
able to add support for using the ScalarEvolution analysis for
load/store pairing (thanks for your help!). This led to a modest
performance increase and a modest compile-time increase. This version
also has a cutoff as you suggested (although the default value is set
high (4000 instructions between pairs) because

AA can become a member of the BBVectorize class and it can be

[RFC][LLD][ARM] Initial ARM port for LLD
Hello everyone,
The review http://reviews.llvm.org/D20951 implements initial support
for the ARM architecture in LLD. To keep the patch size down, and to
avoid the complexities of interworking between ARM and Thumb, there
is just enough support for an ARM only Hello World to link and run on
ARM Linux [*].
My main aim is to get this functionality committed as the basis of an
ARM port and would
