Hi,
We're currently trying to retarget LCC to a toy CPU of our own devising.
I'm sure the book would be extremely useful here, but as useful as it
might be, it's also extremely difficult to get hold of now it would
seem. My work place (a university) doesn't have a copy, and neither does
my local public library (although they've put out a request for an inter-
library loan, that could take weeks.)
Is there any publicly available documentation on the back end?
We've worked out quite a bit, such as the large table of DAGs to
assembler to emit, and how they relate, and how you can chain them.
However, the function entry points seem to have very little in the way of
documentation, and most of the efforts we've found seem to just tweak an
existing back-end until it does what they want - none of the ones we
found target a CPU that's similar enough to what we're doing that we're
happy with that.
An explanation of what is contained in the (tersely-named) members of
structures that these functions manipulate would be a great help, along
with any other insights people might have.
Thanks in advance.
B.
