gdb: Add OpenRISC or1k and or1knd target support This patch prepares the current GDB port of the OpenRISC processor from https://github.com/openrisc/binutils-gdb for upstream merging. Testing has been done with a cgen sim provided in a separate patch. This has been tested with 2 toolchains. GCC [1] 5.4.0 from the OpenRISC project with Newlib [2] and GCC 5.4.0 with Musl [3] 1.1.4. It supports or1knd (no delay slot target). The default target is or1k (with delay slot). You can change the target arch with: (gdb) set architecture or1knd The target architecture is assumed to be or1knd [1] https://github.com/openrisc/or1k-gcc [2] https://github.com/openrisc/newlib [3] https://github.com/openrisc/musl-cross gdb/doc/ChangeLog: 2017-12-12 Stafford Horne <shorne@gmail.com> Stefan Wallentowitz <stefan@wallentowitz.de> Franck Jullien <franck.jullien@gmail.com> Jeremy Bennett <jeremy.bennett@embecosm.com> * gdb.texinfo: Add OpenRISC documentation. gdb/ChangeLog: 2017-12-12 Stafford Horne <shorne@gmail.com> Stefan Wallentowitz <stefan@wallentowitz.de> Stefan Kristiansson <stefan.kristiansson@saunalahti.fi> Franck Jullien <franck.jullien@gmail.com> Jeremy Bennett <jeremy.bennett@embecosm.com> * configure.tgt: Add targets for or1k and or1knd. * or1k-tdep.c: New file. * or1k-tdep.h: New file. * features/Makefile: Add or1k.xml to build. * features/or1k.xml: New file. * features/or1k-core.xml: New file. * features/or1k.c: Generated.
