Chris Lattner 2c14b32e2b New testcase. If one side of and/or is known to be 0/-1, it doesn't matter 
if the other side is overdefined.

Chris Lattner 8d0b1b2a82 Check in the file I forgot last night, to solve all of the crashes in every 
test in the suite.  :(

Brian Gaeke 72daaa46eb JIT should print LLVM each function before selecting instructions for it.

Chris Lattner 7bf2e54dc2 New feature 
llvm-svn: 18797
 2004-12-11 06:10:52 +00:00
Chris Lattner 2f687fd9d6 Two bug fixes: 
1. Actually increment the Statistic for the GV elim optzn
 2. When resolving undef branches, only resolve branches in executable blocks,
    avoiding marking a bunch of completely dead blocks live.  This has a big
    impact on the quality of the generated code.

With this patch, we positively rip up vortex, compiling Ut_MoveBytes to a
single memcpy call. In vortex we get this:

     12 ipsccp           - Number of globals found to be constant
    986 ipsccp           - Number of arguments constant propagated
   1378 ipsccp           - Number of basic blocks unreachable
   8919 ipsccp           - Number of instructions removed

Brian Gaeke b3095dd88f Bools are *also* not ints. Sigh. Furthermore, most of the TargetMachine 
ctor parameters can be defaulted.

Print the transformed llvm code input to the instruction selector
when -print-machineinstrs is on, just like V9.

Brian Gaeke ba5e9f107c Look for many more moves to fold (previously, we only 
*or g0, x      add g0, x          recognized * as a move)
 or  x, g0     add  x, g0
 or  0, x      add  0, x
 or  x, 0      add  x, 0

Brian Gaeke 52a9ed63b5 Make GEPs not suck so much: 
* Don't emit the Index * ElementSize multiply if Index is a constant.
* Use a shift, not a multiply, if ElementSize is 1/2/4/8.
* If ElementSize fits in the immediate field of SMUL, then put it there.

Fix a bug where struct offsets might be truncated (ConstantSInt::get is
now used instead of ConstantInt::get).

Chris Lattner 99e1295645 Fix a bug where we could delete dead invoke instructions with uses. 
In functions where we fully constant prop the return value, replace all
ret instructions with 'ret undef'.

Chris Lattner 9e8141fb3e New testcase that SCCP miscompiles. Luckily this is extremely unlikely to 
happen in practice, but IP-SCCP can trigger it.

them yet.

Chris Lattner 4a03a2d433 Turn on ipsccp by default instead of simple IPCP 
llvm-svn: 18753
 2004-12-10 08:03:43 +00:00
Chris Lattner b439464c61 This is the initial implementation of IPSCCP, as requested by Brian. 
This implements SCCP/ipsccp-basic.ll, rips apart Olden/mst (as described in
PR415), and does other nice things.

There is still more to come with this, but it's a start.
