| stekern | hmm, the target specific code, especially in the toolchain support is really, really messy in clang | 06:48 |
|---|---|---|
| stekern | everything is just hardcoded with if-elses for different archs and other corner cases | 06:49 |
| stekern | I'm a bit reluctant smacking on even more or1k specific stuff there to get 'or1k-linux-clang hello_world.c -o hello_world' work out of the box | 06:52 |
| stekern | (using gcc as a shell for as and ld of course works, but it would be nice to not have the gcc dependency) | 06:59 |
| TarekEldeeb | hello all, I've compiled the or32-elf-sim and toolchain, tried a simple test program .. the simulator cannot decode most of the instructions | 15:36 |
| TarekEldeeb | 00002070: e4832000 <invalid> (executed) [cycle 149, #130] 00002074: 13fffffe l.bf -2 (next insn) | 15:36 |
| TarekEldeeb | What did I miss that caused this behavior ? | 15:37 |

| juliusb | mmm, odd stuff from Tarek there | 18:08 |
| juliusb | stekern: so currently how does LLVM work, though? It relies on GCC's frontend? | 18:10 |
| juliusb | or rather, the work you're doing? | 18:10 |
| stekern | juliusb: no, it "relies" on using gcc as a shell for binutils (as and ld) | 20:33 |
| stekern | i.e. you pass gcc the assembly and let it pass it on to gas and ld with the right commandline options | 20:34 |
| stekern | you could of course just do that manually (and it's done manually in many projects) | 20:34 |
| stekern | or you could define a toolchain in clang (that's what I'm looking at now) | 20:35 |
| stekern | or actually, there is a "Linux" toolchain already defined, but that's not really suitable for us, so I think I'll just create my own "or1klinux" class and set it up like it's set up in gcc | 20:36 |
