what is official way to determine if we are running lto 2nd stage?
Hi,
Imagine that your backend has valid asm instruction written like this:
"%x mnem %y, %z"
And user puts it as inline assembler:
__asm__ ("%x mnem %y, %z");
It can not be parsed with current llvm asm parser, because it starts
with % (moreover it has mnemonic in second place)
Say you written pass, that makes it "mnem %x, %y, %z".
Now this guy can be parsed, but

what is official way to determine if we are running lto 2nd stage?
Hi,
This is really basic block level pass. It is no difference what is
level, problem is the same.
After fixing for asm parser, assembler syntax is no more valid for
backend, without processing with asm parser.
May be it will be solution to process inline asm on insn printer level
to remove syntax fixes. But just switch it off without lto will make
compiler do less job
P.S. sorry for dup,

IceCast Android MediaPlayer support
Thanks.
In http://developer.android.com/about/versions/android-2.2-highlights.html-
there is a support for HTTP progressive streaming. Does this mean that
IceCast is only Android-ready from 2.2?
I've tried some hours ago on Android 2.1 tablet and the app crashes at
start (couldn't find the reason yet). The same app works in 2.3.5.
Thanks, I can extract tags by IcyStreamMeta class.

[llvm dev] do we have allocator hook to use maximum different registers?
Hi,
Default register allocator tries to reuse the same registers over and
over again even if register file have a plenty of registers to use.
This creates parasite false dependencies and makes scheduling less
effective.
How to instruct allocator (may be override some virtual function in
mine backend?) that it is profitable to use maximum number of
available registers with minimal dependencies?

what is official way to determine if we are running lto 2nd stage?
Hi,
In LTO we have AsmParser that process inline assembler instructions to
MCInst and I want to fix some inline assembler in order to conform its
rules (do not start with non-identifier and so on) because asm syntax
of our backend allows some incompatible patterns. In order to do this
I am adding IR-level target-specific pass. But those fixes shall not
be applied when there is no AsmParser later

[GlobalISel] Extended inline assembler support
Hi!
So far, GlobalISel only supports very basic inline assembler constructs
(no input/output operands, only simple memory clobbers).
In [0], I'm adding support for generic register, immediate, memory and
clobber constraints.
The code is more or less a direct port from the handling in
SelectionDAGBuilder.
Before moving on with target specific constraints, I'd like to discuss

Memory scope proposal
Hi,
I have updated the review here:
https://reviews.llvm.org/D21723
As Sameer pointed out, the motivation is:
In OpenCL 2.x, two atomic operations on the same atomic object need to have the same scope to prevent a data race. This derives from the definition of "inclusive scope" in OpenCL 2.x. Encoding OpenCL 2.x scope as metadata in LLVM IR would be a problem because there cannot be a

Memory scope proposal
We believe that it would be best that this is added to the LLVM IR atomic memory instruction as fields on atomic instructions rather than using meta data.
The reasoning is that this information is similar to other information that is represented as instruction fields. For example, the indication that memory operations are atomic rather than non-atomic, the memory ordering of atomics, and whether

nullfs changes MFC
Hi,
I am going to merge latest batch of the nullfs improvements into
stable/9. This will bring up significant performance enchancements due
to use of the shared locks for lookups if the lower layer supports it,
much better caching on the nullfs layer, and proper handling of the text
segments on the nullfs. Also, it should improve the error recovery and
some corner cases with locking.

[LLVMdev] Bad permissions for mapped region
Hi List,
I'm trying to upgrade our llvm-c based compiler from JIT to MCJIT.
While trying to do so I encountered several problems. Looks like C
API does not have proper functions to intialize LLVM with MCJIT.
I ended up wrapping the following functions in my own init routine.
LLVMInitializeX86TargetInfo();
LLVMInitializeX86Target();
LLVMInitializeX86TargetMC();
LLVMInitializeX86AsmPrinter();

while you might think so, try it the other way round. Also, by doing
make VERBOSE=1
you can see which compiler is really being used.
