Chris Lattner d61b13c6e2 Disable strict alias analysis in the backend c compiler, as the code we 
generate is not TBAA safe.

Chris Lattner a182f5bf48 Revert previous patch, I'm a moron :)

Chris Lattner 177fe8d82f Right, we break strict aliasing requirements. Make sure to disable strict 
aliasing in the C compiler.

Chris Lattner 4d25c86b52 Remove the "really gross hacks" that are there to deal with recursive functions. 
Now we collect all of the call sites we are interested in inlining, then inline
them.  This entirely avoids issues with trying to inline a call site we got by
inlining another call site.  This also eliminates iterator invalidation issues.

Brian Gaeke 6d62df5422 First version of code to handle loads. Stub function for handling stores. 
llvm-svn: 12758
 2004-04-07 17:29:37 +00:00
Brian Gaeke 989c04ab58 Support loading arguments from %I0...%I5 into virtual registers in 
function prologues, and fix an off-by-one in visitCallInst that was
putting call args into the wrong registers.

llvm-svn: 12757
 2004-04-07 17:04:09 +00:00
Brian Gaeke 7985e56cf9 It's setting up the call args right now, but on the callee side, it's 
trying to get incoming args off the stack, instead of the %i0...%i6 regs,
which is wrong.

Fix a typo.
Add a project I've always thought would be cool.

Chris Lattner d93de7a754 New file that can be useful for hand inspection of assembly required for certain 
kinds of instructions.

llvm-svn: 12746
 2004-04-07 05:06:39 +00:00
Chris Lattner bd58b3fbe9 This is a start on handling setcc instructions. As the comment notes, we 
have no good way of handling this until the code generator is improved.
We should probably just emit V9 instructions in the meantime.

llvm-svn: 12733
 2004-04-07 04:01:00 +00:00
Brian Gaeke cfbfb8ac57 Preliminary support for getting 64-bit integer constants into registers. 
Preliminary support for division. It's gross because you have to initialize
the "Y" register, which is the top 32 bits of the thing you're dividing.

Brian Gaeke 3915ad7c02 First attempt at special-casing printing of [%reg + offset] for 
ld/st instructions - doesn't seem to work yet, but I think it's
just a typo or something somewhere.

Brian Gaeke 2e91a3d650 Deal with call return values. 
Don't put NOPs in delay slots at all. We'll have a fix-up pass later.
