...used in loop condition not/ I would like the community's opinion on whether this is something worth fixing? In this case, should the output always be the same irrespective of the iteration order? If yes, then we have 2 alternatives: 1. Change SmallPtrSet to SmallVector for the container (VarDecls) being iterated - this may have a compile time impact (need to measure). 2. Sort the container (VarDecls) before iteration. We can sort based on decl source location and decl name. Not sure if these guaranteed to be unique?

With recent work a plugin can now Annotate a VarDecl at the AST level, how can this be used in a Pass at the IR level? What classes are responsible for their manipulation? I assumed it would be part of Value, or something common like it, but I do not see any mentions of Annotation or Attribute. Thank you -------------- next part -------------- An HT...

...ective. Phil, Below are 2 main things we need to change from NE10 Library side. Can you please make these changes on NE10 side? 1. Remove usage of _t in ne10_fft_cfg_float32_t and ne10_fft_cpx_float32_t -------from comment---- ne10_fft_cfg_float32_t cfg = (ne10_fft_cfg_float32_t)st->priv; + VARDECL(ne10_fft_cpx_float32_t, temp); + VARDECL(ne10_fft_cpx_float32_t, tempin); Just another note on API design... the _t suffix is reserved by POSIX, and should never be used by user code. It's unlikely to cause issues with these long type names, but I have certainly seen it cause issues elsewher...

Tim, et al, I have run into several problems with V0.8.0. I will address them seperately. 1. My compiler is complaining about the following code in celt.c which seems to define metric first as celt_word32, then as celt_word16. Am I mis-interpreting something? ?? VARDECL(celt_word32, metric); ?? ALLOC(metric, len, celt_word16); Thx MikeH -------------- next part -------------- An HTML attachment was scrubbed...

I created a plugin to add simple Annotations to VarDecls and FieldDecls, and write this modified AST out to a file. I notice that when I use clang to compile this file I get different code then when I use the source directly. In both cases I'm compiling with -O4. Can anyone explain this?

...() is used only in nb_celp.c, and sb_celp.c re-uses the stack from the nb en/de-coder. But the echo-canceller and preprocessor don't use it. I suppose they also have some scratch buffers. (comments in SpeexEchoState_ structure mdf.c) But you allocate them with speex_alloc instead of using the VARDECL/ALLOC macros. Converting the code to the stack_alloc mechanism could result in better performance with a scratch buffer in SRAM. I think I can do it for mdf.c, but I would need information for preprocess.c. -- St?phane LESAGE ATEIS International

Hi, In case it is of any help, to compile a static library for the iPhone, I had to add the following 2 lines in plc.c file : #include "arch.h" #include "stack_alloc.h" otherwise "celt_word16..." type are not defined and "VARDECL...." also not. Best Regards St?phane Letz

Hi all, This is Linfeng Zhang from Google. I'll work on ARM NEON optimization in the next few months. I'm submitting 2 patches in the following couple of emails, which have the new created celt_fir_neon(). I revised celt_fir_c() to not pass in argument "mem" in Patch 1. If there are concerns to this change, please let me know. Many thanks to your comments. Linfeng Zhang

Hi LLVM Devs, I am in the process of building my own plugin for Clang/LLVM in Windows on Visual Studio. I am having difficulty generating the .dll shared file to use at compile time. How have the .dlls corresponding to the example plugins been built?
