...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.

Hi Timothy, Appreciate the comprehensive code review. The biggest issue I see is the peak stack usage.... rest looks like fairly straight forward cleanup. Is the peak stack usage a complete blocker in current form? If it is indeed a blocker, would it be acceptable if we can reduce additional buffer requirement from 2 buffers (current) to 1, possibly by moving scaling inside

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

Dear All, I have a question How could I use WhileStmt class in Stmt.h http://clang.llvm.org/doxygen/Stmt_8h_source.html to implement while loop like while(i==1){} that is required to be inserted For example, Convert x++; y++; to x++; while(i=1){} y++; from the class's constructor: WhileStmt(ASTContext &C, VarDecl *Var, Expr *cond, Stmt *body,SourceLocation WL);//I know C -->

Hi Mark, I don't know anything about Clang's annotations or attributes, but from what you describe it sounds like you want to attach metadata to Values? Try searching for "metadata" instead, that should get you more results :) Cheers, James From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Mark Brown Sent: 22 September 2011 07:46 To:

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?

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

Gents, I am getting the following compile error on V11.1 "declaration may not appear after executable statement in block". This occurs in two places in celt.c. ============================================================================ ==================== #ifdef FIXED_POINT #ifndef DISABLE_FLOAT_API CELT_STATIC int celt_encode_with_ec_float(CELTEncoder * restrict st, const

No, I need to use it in LLVM pass. Could it work?

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? This works: clang -fplugin=C:/Users/User/llvm-project/build/Release/bin/PrintFunctionNames.dll -Xclang -plugin -Xclang print-fns test.c This

Hi Jean-Marc, Hi Jim, I have also seen some problems with the 1.1.8 release on the C55x. So far I have boiled down the issues to the following: 1) We need our own "fixed_xx.h" header file. I don't know why, and haven't had time to investigate, but there is a definite improvement when I use the attached fixed_c55x.h file which has turned all the maths into inline functions.

Hi All, I need your guidance about a custom attribute. I have defined one for variables. It is accepted in the source code (without any warnings from clang), for example in following snippet. #define NEWATTR __attribute__((moviAttr(1))) int main() { NEWATTR volatile unsigned int a = 5; volatile unsigned int *p; p = &a; return (a+*p); } and actually when I Dump the declaration, after
