We need none on 64-bit, and only 16 bytes on 32-bit. - Ali...

...operate on the serial port. To me, the most sensible approach would be to port newlib to the LLVM virtual machine, and use LLVM intrinsic functions as placeholders for the actual system calls. The back end would then emit target specific code for the intrinsics. What I don't quite see is how crt0 fits in the picture. Am I right in assuming that when llvm-gcc emits LLVM byte code, there is no crt0 involved? I haven't checked how the other back ends do it, but I assume that they rely on the host libc and crt0. In my case, I envision libc being linked in at the bytecode level, and crt0 bei...

We are going to use LLVM in a compiler project for transport triggered processors. See Wikipedia for more on transport triggering: <http://en.wikipedia.org/wiki/Transport_Triggered_Architectures>. One thing we need is some sort of libc. We are targeting embedded systems, and I have been looking at things like newlib. Are there people out there doing something similar? Or any advice or

After a couple of very late nights I actually have a VERY preliminary test of the rewritten SYSLINUX available for preview. However; don't expect it to do anything miraculous yet; the testing it has gotten can best be described as infinitesimal. In theory, though, it should now support EDD and FAT32, as well as FAT filesystems with very large clusters (up to 64K). NOTE: The Win32
