1* Writing out ELF files is close to working but the following needs to 2 be examined more closely: 3 - Relocations use 2-byte / 4-byte to terminology in reference to 4 the size of the immediate value being changed. The Xilinx 5 terminology seems to be (???) 4-byte / 8-byte in reference 6 to the number of bytes of instructions that are being changed. 7 8* Code generation seems to work relatively well now but the following 9 needs to be examined more closely: 10 - The stack layout needs to be examined to make sure it meets 11 the standard, especially in regards to var arg functions. 12 - Look at the MBlazeGenFastISel.inc stuff and make use of it 13 if appropriate. 14 15* A basic assembly parser is present now and seems to parse most things. 16 There are a few things that need to be looked at: 17 - There are some instructions that are not generated by the backend 18 and have not been tested as far as the parser is concerned. 19 - The assembly parser does not use many MicroBlaze specific directives. 20 I should investigate if there are MicroBlaze specific directive and, 21 if there are, add them. 22
