similar to: [LLVMdev] annotations preventing optimizations/cleanup?

This is how clang implements annotations on local variables, that's all.

Hi Asit, thanks for the reply. But I guess I was not clear in my question. Actually, i dont want to use __ATTRIBUTE__((ANNOTATE("MOVIATTR"))), since in documentation it is stated that "This intrinsic allows annotation of local variables with arbitrary strings. This can be useful for special purpose optimizations that want to look for these annotations. These have no other

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

Hi, I have: ... @.str1 = private unnamed_addr constant [21 x i8] c"Now f is a function\0A\00", align 1 ; Function Attrs: ssp uwtable define i32 @_Z1fv() #2 { entry: %call = call i32 (i8*, ...)* @printf(i8* getelementptr inbounds ([21 x i8]* @.str1, i32 0, i32 0)) ret i32 0 } Then I get after trying to erase the function from the module: 511

Hi John, I have looked into the EmitAutoVarAlloca() in CGDecl.cpp. However, I could not figure out how to employ my custom attribute for code generation. For example, my custom attribute is visible in CGDecl.cpp but how can I generate based on my custom attribute if (D.hasAttr<myCustomAttri>()) { //What to do here? } What I wan in IR is something like below. Without Custom Attribute:

If I use a simple dtrace script such as this: fbt::somefunc:entry{self->trace=1;} fbt::somefunc:return{self->trace=0;} fbt:::entry{} fbt:::return{printf("%lx", arg1);} then it will descend to whatever depth is necessary If I want to limit it to say 3 functions deep, how can I do that? The quick answer I want to use is to do "self->depth++" on each entry and then

What''s the difference between these two?

Dear list, I have a data frame of survey respondents, a little like this: set.seed(20081215) n <- 100 dat <- data.frame(id=1:100, addr1=sample(LETTERS, n, replace=TRUE), addr2=sample(LETTERS, n, replace=TRUE), addr3=sample(LETTERS, n, replace=TRUE)) head(dat) id addr1 addr2 addr3 1 1 R H Q 2 2 H C K 3 3

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:

Hi, suppose I do: b <- matrix(1:9,3,3) bname <- "b" now dim(b) returns [1] 3 3 and dim(bname) returns NULL is there a function to pass bname to such that dim returns the dimensions of b? like dim(somefunc(bname)) returns [1] 3 3 does 'somefunc' exist? daver +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |David Richmond It

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, I have migrated an LLVM front-end from LLVM 3.5 to 3.8 and now to 3.9 and ORC, and there is a concept which I could not transfer. Consider: extern "C" { void somefunc() {} } … auto llvmfunc = llvm::Function::Create(type, llvmFunction::PrivateLinkage, "bla", module)); executionengine.addGlobalMapping(llvmfunc, &somefunc); // now I have llvmfunc to work with and

I am sure some of you can give me an insight into this. This is more towards the database design for the scenario below: Say for example, I have a person table and this person can have different address types. One could be Home and the other could be say Office. Should be model this Table people id fname lname Table addresses id person_id addr1 addr2 .... or Table people id fname lname

I see that the following test fails if reverse iteration of SmallPtrSet is enabled: /clang/test/SemaCXX/warn-loop-analysis.cpp/ This is because in SemaStmt.cpp we iterate SmallPtrSet and output warnings about the variables not used in the loop. Expected output: /warning: variables 'i', 'j', and 'k' used in loop condition not modified/ Output with reverse iteration:

Hi, I have a question about redirecting message to a multiple addresses. I have an user script like following: require ["copy"]; redirect :copy "addr1 at dom.ain"; redirect :copy "addr2 at dom.ain"; All works fine, but if addr1 at ... has exceeded quota, this script seems stop working and addr2 at ... doesn't receive this message too. Is this correct

All, Currently, the Win32::API.new method will search for the function name, then the ''A'' (ANSI) name, and finally the ''W'' (Wide) name. The code looks something like this: fProc = GetProcAddress(hLibrary, TEXT(RSTRING(v_proc)->ptr)); if(!fProc){ VALUE v_ascii = rb_str_new3(v_proc); v_ascii = rb_str_cat(v_ascii, "A", 1); fProc =
