[LLVMdev] bytecode cache
I think the way to do this is to generate a shared library which you
reload. Shared libraries already handle the problems of PIC code and
relocatable globals, so I think it would be best to leverage that.
However, there's obviously some issues here. Presumably you don't
have all the code up front, or you wouldn't be using a JIT in the
first place. I don't think you can update

[LLVMdev] folding x * 0 = 0
Hi!
> sin/cos etc should already be handled by lib/Analysis/ConstantFolding.cpp.

Thanks for the hint and it works!
Now I have a new Problem:
I have this function:
float foo(float a, float b)
{
float x = a * b * 0.0f;
return cos(0.5) * sin(0.5) * x;
};
after compiling it with clang (cpp mode) and renaming _ZSt3sinf to sin
and _ZSt3cosf to cos I get the following:

[LLVMdev] request for windows unicode support
Hi!
Of course nobody wants to implement unicode support for windows
because windows should support an utf8-locale and windows is obsolete
anyway ;-)
But there is a simple solution: use boost::filesystem::path everywhere you
use file names and paths, for example in clang::FileManager::getFile.
With version 3 opening a file is easy: std::fstream file(path.c_str()).
Internally

Is x*0 => 0 true if isnan(x)?
And cos(x)*sin(x) makes me desperately want to fold it to sin(2*x)/2,
but I suppose that's not allowed either.

But if a backend sees trunc from i8 to i1 it should know

[LLVMdev] Please add .o writer example to next release
Hi!
Is it possible that you add an example how to write a .o with llvm?
Just like examples/ModuleMaker but instead of printing to stdout
writing a .o file as starting point for the new MC functionality.

[LLVMdev] DataTypes.h for Visual C
Hi!
In DataTypes.h (generated from DataTypes.cmake) there is an extra
code path for Visual C.
This can produce macro redefinitions for INT8_MAX, INT8_MIN etc.
since other headers may also define them. Therefore please
protect the macros like INT8_C etc.
Also it would be nice if the auto-generated HAVE_STDINT_H
and HAVE_INTTYPES_H would be used also for Visual C since it
is possible to add them

[LLVMdev] constness of APFloat::toString

I wonder if llvm::APFloat::toString() can be const since
it should not modify the APFloat.

[LLVMdev] Using LLVM with clang for a homebrew kernel
Hi!
In the llvm-doc is the following:
Also, since many platforms define their ABIs in terms of C, and since
LLVM is lower-level than C, front-ends currently must emit
platform-specific IR in order to have the result conform to the platform
ABI.
Can you give an example for this except system calls (which e.g. on
windows use
a different calling convention)?

[LLVMdev] [cfe-dev] conditional operator
Hello Jochen-
Your expectation is incorrect, I'm afraid. Typically this would be expanded
to something like this:
…
%cmp = …
br i1 %cmp, label %ternary.true, label %ternary.false
ternary.true:
%truevalue = …
br label %ternary.end
ternary.false:
%falsevalue = …
br label %ternary.end
ternary.end:
%value = phi %type [%truevalue, %ternary.true], [%falsevalue,

[LLVMdev] function inlining
Hi!
I have a llvm::Module that references an external function
and a second mdoule that implements the function.
The implementation consists of only one instruction.
How can I explicitly inline this function?

[LLVMdev] vector optimization
Hi!
Is there a pass that optimizes vector operations?
If I have for examle a sequence of shufflevector instructions
that optimizes them?
