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.
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
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.
