* Reverting the commit 116986. It was breaking the build on llvm-x86_64-linux ↵Wesley Peck2010-10-211-44/+165
| | | | | | | | | | though it compiles on OS X. I'll ensure that it builds on a linux machine before committing again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116991 91177308-0d34-0410-b5e6-96231b3b80d8
* Major update of the MicroBlaze backend. The new features are:Wesley Peck2010-10-211-165/+44
| | | | | | | | | | | | | | | | | | | | | 1. A delay slot filler that searches for valid instructions to fill the delay slot with. Previously NOPs would always be inserted into delay slots. 2. Support for MC based instruction printer added. 3. Support for MC based machine code generation and ELF file generation. ELF file generation does not yet completely work as much of the ELF support infrastructure is still x86/x86-64 specific. 4. General clean up of the MBlaze backend code. Much of the tablegen code has been cleanup and simplified. Bug Fixes: 1. Removed duplicate periods from subtarget feature descriptions. 2. Many of the instructions had bad machine code information in the tablegen files. Much of this has been fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116986 91177308-0d34-0410-b5e6-96231b3b80d8

The MicroBlaze is a highly configurable 32-bit soft-microprocessor for use on Xilinx FPGAs. For more information see: http://www.xilinx.com/tools/microblaze.htm http://en.wikipedia.org/wiki/MicroBlaze The current LLVM MicroBlaze backend generates assembly which can be compiled using the an appropriate binutils assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96969 91177308-0d34-0410-b5e6-96231b3b80d8
