Hi Wesley, I've done quite a lot of work on register allocation for stack machines. You might want to look at my papers: http://www.dcs.gla.ac.uk/~marks/euroforth.pdf http://www.dcs.gla.ac.uk/~marks/thesis.pdf Good luck, Mark. -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu on behalf of Wesley J.

Hi, Does anyone know an easy way to do same optimisations as 'opt -O2' or 'opt -O3' in the JIT. I can do the tedious way: pass_manager->add(createInstructionCombiningPass()); pass_manager->add(createGVNPass()); etc. etc. but I would rather reuse the code in 'opt' to manage the passes. Cheers, Mark. -------------- next part -------------- A non-text

Hi, When compiling this function: __attribute__((fastcall)) int f(int x, int y) { return 0; } llvm 2.3 produces the following x86 assembler (with directives removed): f: xorl %eax, %eax ret $4 Where as GCC (version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) produces: f: xorl %eax, %eax ret Note the difference in ret. Functions calling a fastcall function in llvm adjust the stack by 4 to

Hi everyone, I don't know if this is a bug or I am misunderstanding things. I couldn't find anything in the Bugzilla database. The following code: 1 @sp = external global i8** ; <i8***> 2 3 define void @test(i8* %x) { 4 entry: 5 load i8*** @sp ; <i8**>:1 6 getelementptr i8** %1, i32 1 ; <i8**>:2 7 store i8** %2, i8*** @sp, align 4 8 ret void 9 } causes llvm-as

Hi everyone, llvm is great! But there is one exception ;) llvm components are generally fast, but instruction selection is slooow. Let me explain. I am developing a toolkit for building virtual machines which can automatically generate a JIT compiler using the interpreter specification. llvm does the hard work of machine code generation. (Thanks to you all) I discovered that JIT compilation is

Dear developers, When I try to map line numbers in source code back to LLVM basicblocks, I meet some problems: there is a source file with 1500 lines of code, but when I use BasicBlockPass to collect all DbgStopPoint instructions in this file, I can only get 500 lines of code. The source code and the collected results are both attached. Is there any way to map line numbers

Hi, I hope it is ok to send questions to this list as a mere user of speex, but I couldn't find any reference to newsgroups or any reference to Delphi in past threads of this list. I would love to use speex in a Delphi application, but the plugin example provided in the speex website is missing a speex DLL and a speex Delphi unit. Does anyone know where I can find them, or how to contact

But is there any sound player for windows that plays speex in an ogg container? One more question, besides the source code found in the speex site (like speexenc.c) can you tell me where to find source code developed in C++ (using object oriented programing) that makes it easier to write ogg files with speex content?

When I use speexenc appplication to encode a wav file and then speexdec to decode it the decoded wav is bigger than the original, why this happens? Thanks.
