Hi, all right, no fixed point type in LLVM :-( May I ask then, what could one expect from various optimizations when using intrinsics to support the fixed point type? LTO, Value optimizations, mem ?? Are you saying it is feasible to add intrinsics and some extra optimizers for these, then? Best regards, Jonas > Subject: Re: [LLVMdev] fixed point types > From: clattner at apple.com >

<retitling to be useful> LLVM shouldn't have a fixed point type class. You should just use standard integer types. Supporting fixed point and saturation should by done by adding new operations to llvm IR. If you're interested in this, I'd suggest starting by implementing these as intrinsics. If it makes sense over time we can change them to primitive instructions if there is

Hi, thanks a lot for the answer. By mem, I meant optimizations that involves load/store intrinsics, eg llvm.fixPload(). What would the consequences of this be? I ask then, is there any interest at all in the LLVM community for fixed point support in the future? Are there even any local successful projects that you know of? Did you mean that fixed point support in terms of intrinsics and code

You probably meant to send this to LLVMdev as well.

Hi, [Re-cc'ing list - please hit "reply to all"! :) ] You can't just use your system C and maths libraries when cross-compiling. The C and especially math libraries make lots of assumptions about the underlying system - ABI, endianness and most importantly the assembly language for inline assembly. You will need to cross-compile a C or math library. Cheers, James From:

LTO, Value optimizations, mem ?? You'd have to implement explicit support for the new intrinsics in various places. For

Hi, is it possible to reduce link time by excluding unused target backends? I would like to type tools/llc make -target=... , and just build it for one backend. /Jonas -------------- next part -------------- An HTML attachment was scrubbed...

If you build with configure && make, use the configure option --enable-targets. If you build with cmake && make, pass

To: Andrew Trick Hi, I write you directly as you are the commiter of the code I am having problems with for my target - see below. I wonder what you think about this?

Yes, I'm saying that the implicit-def operand that was added in this case ended up as #4, out of 6, when the operands list was reallocated in addOperand(). If addOperand was rewritten, I think it's best not to add my fix for ProcessUses(), as I wrote earlier.

I have a few pass managers, but only one of them has been initialized with addPassesToEmitCode, how do I find how many passes are added to a function pass manager ?

Hi Anshu, Would there be any interest in extending this algorithm to handling more extensive models, such as VLIW scheduling based on FU's and bundle space... ie handle multiple stages ? I might do it and commit, if there is acceptance and guidance...

I see, thanks. I used to work with GCC, which has an SSA-property verification run after each pass. It is surprising to find that LLVM does not check this!
