[LLVMdev] clang and static functions
Ah ok. Sorry. :)
I think that argument "-femit-all-decls" will help you.

[LLVMdev] clang and static functions
Hi,
Sorry for not being specific. I just wanted to know if there is any
way at all to force clang to generate intermediate code for static
functions when they are not being called anywhere inside the current
module. Other compilers seem to generate intermediate code (lcc, for
instance).
Thanks for your reply..Olivier.
Sincerely

[LLVMdev] clang and static functions
Hi Arvind,
you need to use it effectively :
static int add(int a, int b) {
return a+b;
}
int use() {
return add(4,5);
}
==>
; ModuleID = '<stdin>'
target datalayout =
"e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64-f80:32:32"
target triple = "i386-pc-linux-gnu"

[LLVMdev] clang and static functions
Hi,
I am trying to compile a single module (dgemm.c) using clang and
generate dgemm.ll.
Command: clang -emit-llvm dgemm.c -S -o dgemm.ll
Some of the functions are declared as static and clang ignores these functions:
One of the functions is:
static void innerloop(double a, const double* b, double* c, double beta)
{
*b = a*beta;
return;
}
Is there any way to make clang generate llvm code

[LLVMdev] Trying to access the user defined variable name
Hi Devang,
Thanks for your reply. You mentioned
" First parameter is the compiler generated temp. and 3rd parameter
provides info about the variable, including its name 'u'."
I did manage to get this far. But, I am finding it difficult to access
this info using LLVM APIs. The third parameter is of type "metadata".
So I was able to access it by casting it to MDNode.

[LLVMdev] source code information in LLVM IR
Hi,
I am generating llvm IR code for C source code using clang as the
front end. I am wondering if there is any way of mapping an llvm IR
line number back to its C source code line number.
Thanks
Sincerely
Arvind

[LLVMdev] regarding getelementptr
Hi,
I got the "getelementptr" issue solved...John Criswell helped
me...Thanks, Duncan, for your reply.
I have another query though. When I try to pass a structure into a
function in my C program, if there are less than four scalars in the
structure, the clang tool creates llvm code where the structure is
passed as sequence of scalars. If there are more than (or equal to)
four scalars,

[LLVMdev] Qualitative comparisons between Open64 and llvm
Hi, Arvind Sudarsanam:
I know some of Open64. Above all, Open64 is designed for a high
performance compiler. It is now supported by AMD, HP, ICT Chinese
Academy of Science, etc. and has been ported to X86, Itanium, Loongson
CPU etc.
And to your questions
1, Open64 already have some main optimization phases, Inline for
aggressive inline opt. LNO for loop opt, WOPT for machine independent

[LLVMdev] Qualitative comparisons between Open64 and llvm
Hi,
I have been working towards developing compiler optimization tools
targeting multi core processors while using LLVM IR as the starting
point and building on top of the analysis and optimization passes
available in the llvm source.
Recently, I looked into Open64 and its intermediate representation
WHIRL. Documentation for developers to use Open64 seems to be inadequate

[LLVMdev] argpromotion not working
Hi all,
I have the following C code.
static int addp(int *c, int a,int b)
{
int x = *c + a + b;
return(x);
}
I want to replace *c with a scalar. So I tried the -argpromotion pass.
However, it fails to do anything to the resulting llvm file.
List of commands:
clang add.c -c -o add.bc
clang add.c -S -o add.ll
opt -argpromotion -stats add.bc -o add_a.bc
llvm-dis < add_a.bc > add_a.ll

[LLVMdev] Operand, instruction
Can you tell how to use vector globally? I mean, i am able to add entries to
a vector in a basicblock, but whenever a basicblock function call is
returned, the vector becomes empty. So how to use data structures globally?
And one thing, where is main ( or same kind of) function in llvm?
Thanks for you reply.

[LLVMdev] LLVM build freezes in scratchbox, ARM target

I am new to LLVM and have been trying to get it working on

I think you are using an old llc version. VarArg support was
implemented a long time ago.

[LLVMdev] llc fails to generate code for arm
Hi
Sorry for the late reply..
I managed to build the latest release of llvm.
Now I get the following error when I try creating the bitcode file:
llvm-gcc: --emit-llvm is not supported in this configuration.
The configure options were :
