* Add __ashrdi3 and remove link to libgccFranck Jullien2012-09-141-4/+0
| | | | | | | | | In a previous patch, Sascha needed to add __ashrdi3 and then linked to libgcc. This patch add the ashrdi3 function in the arch/openrisc/lib directory and remove the libgcc dependency.

* openrisc: link to libgccSascha Hauer2012-06-281-0/+4
| | | | | | | | | | | To get symbols like __ashrdi3. Franck started generating these symbols from gcc assembly, which seems to be the cleaner approach. The simpler approach for now to get additional symbols is to link in libgcc, which is the same as the kernel does.

OpenRISC is the original flagship project of the OpenCores community. This project aims to develop a series of general purpose open source RISC CPU architectures. A team from OpenCores provided the first implementation, the OpenRISC 1200, written in the Verilog hardware description language. Even though I should have created an mach-or1200 directory, it is not necessary for now. The OpenRISC 1200 CPU is the only one available and it will be for some time.
