similar to: [LLVMdev] An alternate implementation of exceptions

Hi Mikael, the idea of modifying functions so they return two parameters (the usual one and an exception pointer or some kind of exception flag) is well known. The LLVM vmkit project actually uses a variant of this: rather than returning the exception pointer in a register, it sticks it in a global thread local variable. I only took a quick look at your paper, but it seems to me that it has a

Hi Duncan, I agree on the problem about linking with code - I actually do mention this in the paper. I propose adding a new calling convention called "excall". The central point of my paper is that only one parameter is needed as the return value (because of the use of the flag): the EAX register can safely be used for both the exception instance and the return value as these never

That's not the cmake documentation, that's the LLVM cmake documentation: a short document that tries to explain everything you need to know about cmake to build LLVM.

Thank you so much for your hard work! LLVM/Clang is in need of motivated Windows developers willing to put in the time to make the LLVM/Clang experience better on Windows :) Quick note on the reST: instead of using a construct like: **Notice:** If you only want to build 32-bit programs, you do **not** need to install MinGW64. Prefer to use the reStructuredText "admonitions" <

Yes, sorry, the LLVM CMake documentation :-) I don't think I am duplicating a large chunk; I am continuously trying to shave off extraneous and redundant stuff off my Windows-specific document. I just managed to shave off about six lines or so because I don't like the huge introduction and explanation of what MinGW is. Now that the document covers Ninja, there's even more reason for

Hi, I stumbled across three warnings in LLVM when building with MS Visual Studio 2010. It has been my experience that different compilers detect different things, so I thought I'd pass them on to you (in case your compiler does not warn about these things): warning C4805: '==' : unsafe mix of type 'bool' and type 'unsigned int' in operation

We should make LLD to be able to build with GCC even if GCC is a bit buggy. So you wrote that it's no longer build because of the recent change of makeArrayRef removal? I think it's my change (r196475). Can you confirm that you can build if you revert that change? If it has caused the build with GCC to break, we should roll it back.

The website is at http://llvm.org/viewvc/llvm-project/www/trunk/ . The llvm docs are in llvm/docs. Which actually makes me wonder if the LLVM-project FAQ (in reference to Chandler's post in

I tried this command to undo the change (which should revert to the change just before the one you mentioned): svn update -rr196474 Then I built from scratch. This time it built, so I suppose it is revision 196475 that is the problem. -- Mikael 2013/12/9 Rui Ueyama <ruiu at google.com> > We should make LLD to be able to build with GCC even if GCC is a bit > buggy.

I'll use a redirection to the new article then. Did you try out the .htaccess thingy we talked about on LLVM.org? It should work, without any webmaster's assistance. 2013/11/21 Sean Silva <chisophugis at gmail.com> > > > > On Wed, Nov 20, 2013 at 6:11 PM, Mikael Lyngvig <mikael at lyngvig.org>wrote: > >> Hi Renato, >> >> My XU is on build

Now I can't make CMake use "MSYS Makefiles". I get an error about GNU v4.7.0 being broken as it can't build a simple test program. Using "MinGW Makefiles", everything works out of the box. And I am trying to give the user the most Windowsy experience (to avoid Cygwin, GnuWin32, and MSYS, if I can). So I think I'll stick to my current angle - which is to let the

StackOverflows says two things: 1. An example is: <meta http-equiv="refresh" content="0; url= http://example.com/" />. 2. This apparently discouraged by the WWW Consortium who recommends server redirects. It seems that LLVM.org is served by Apache 2.2.22 running on Ubuntu. In that case, the .htaccess file should make it possible to do server redirects:
