Hi, As far as encapsulation is concerned, that's your decision (and sticking the Symtab in a separate class is a good idea). I was more checking that this symbol analysis is being done *on* your AST - so at the AST phase of compilation.

Maybe this is not LLVM specific, but more or less related. The language I'm implementing allows the programmer to define complex data structure like Pascal records. How am I suppose to design the symbol table? What should be recorded there? Just the type name or each of the record element must be stored? -- View this message in context:

leledumbo, from what you say, I assume you have some kind of representation (AST or a lower-level intermediate representation) from which you generate LLVM assembly. Is this representation in SSA form? If it is, you might want to do a "copy propagation" transformation that replaces the uses of all variables that are assigned a constant value by their definitions. Example: x = 5 y =

I have an AST, and I walk it to generate llvm-IR. For function definitions, I need to be able to generate functions : vector<datatypes> foo (param_list) i.e. my return value is a vector of different datatype.s, similar to the param list. My question is, what do i put my elelment type in the vector? It can be a vector of any of the element types.. i.e. the first value can be a float, the

Hi! I have some problems with build current CVS version LLVM using GCC 4.1.0 (GCC CVS mainline version). 1) Build terminate with error: llvm[3]: Compiling SparcV8CodeEmitter.cpp for Debug build /usr/home/wanderer/pkg/build/llvm/obj/lib/Target/SparcV8/SparcV8GenCodeEmitter.inc:11: error: definition of 'unsigned int

Hello all! I am currently trying to sort a data frame in a particular way, but I am having some difficulties with this. Specifically I want to sort the below dataset in such a way that there is only one line per ProteinID and if there are multiple GeneID or GeneName entries for a single proteinID, that they be concatenated with a comma separating them. The way I have done it earlier worked fine

Hi, I'm working on a project to generate native code for a domain specific langauge where the user defines functions in the complex plane. This implies that I need to support complex numbers as a datatype with LLVM. Its fairly straightforward to create a struct of two floats (or doubles, etc.) and do the simple operations like add, subtract, multiply, divide, etc. However, things get

hi guys, i use clang to compile a program with datatype uint, but i get errors saying " use of undeclared identifier 'uint'; did you mean 'int'? ". it really doesn't support it? if true, how can i add a datatype? -- View this message in context: http://llvm.1065342.n5.nabble.com/donot-support-uint-datatype-tp52523.html Sent from the LLVM - Dev mailing list archive

Dieter Menne pointed out that the (small) xml attachment didn't make it. Here is an in-line version (see end of message). Let's hope it works this time. I'm struggling with interpreting XML files created by ADODB as data.frames and I'm looking for advice. Note: This xlm contains a result set which comes from a rectangular data array. I've been trying to play with

I have tables with double as their field''s datatype. When I ran db:schema:dump, Rails changed all of these double to float. I would like to know why, and if there is anyway I could preserve the datatype.

I have a project I want to do based on Libfuzzer. Is there a separate list for it or should I bring up any ideas for it here? What I have in mind is to fuzz Postgres. Trying to fuzz the SQL interpreter in general is not very productive because traditional fuzzers try to execute the entire program repeatedly and it has a fairly high startup and shutdown cost. Also the instrumentation-guided

Hi, If x is a local variable, it will be stored on the stack. So you need an alloca for it: %x = alloca i8 ; <i8*> Then you can just perform a store: Store i8* %x, i8 0 Cheers, James > -----Original Message----- > From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] > On Behalf Of leledumbo > Sent: 20 October 2010 14:39 > To: llvmdev at

Hi there, I have a Java process that writes HDF5 files with the following approximate structure: group "xxx" { group "yyy" { dataset {} dataset {} } group "zzz" { dataset {} dataset {} } } where dataset is a rank one dataspace having a compound datatype defined as: H5T_UNIX_TIME, float, float, float, float I

Hi, ? To get the memory address of where the value of variable "x" (of datatype "numeric") is stored one does the following in R (in 32 bit): ? ??? ? library(pryr) ? ?? ?x <- 1024 ?? ?? addr <- as.numeric(address(x)) +?24?? ?# 24 is needed to jump the variable info and point to the data itself (i.e. 1024) ? The question now is what is the value of the jump?so that one

I would like to convert a dataframe to an array of lists, one for every record. A natural choide is apply as.list to the rows. However, as it seems, as.list() automatically converts all list elements to the same datatype. Eg: myData <- data.frame(a="foo",b=as.logical(rbinom(10,1,.5))); apply(myData,1,as.list); In this output, all boolean values have been converted to character
