Chris Lattner d420fe63ea Implement a FIXME: if we're going to insert a cast, we might as well only 
insert it once!

John Criswell e3e2c91997 Remove code to adjust the iterator for llvm.readio and llvm.writeio. 
The iterator is pointing at the next instruction which should not disappear
when doing the load/store replacement.

Brian Gaeke 0174347d9a Fix typo.

Chris Lattner 8a9fd94cfe This is a trivial tweak to the addrec insertion code: insert the increment 
at the bottom of the loop instead of the top.  This reduces the number of
overlapping live ranges a lot, for example, eliminating a spill in an important
loop in 183.equake with linear scan.

I still need to make the exit comparison of the loop use the post-incremented
version of this variable, but this is an easy first step.

Brian Gaeke aec2bcd63b Add a TargetData to the PassManager regardless of the TargetMachine. 
This should unbreak the Sparc JIT again.

John Criswell c4e72c9a0a Remove the return type check for llvm.readio. This check is done for all 
functions and is not needed here.
Simplify the pointer type check per Chris's suggestions.

llvm-svn: 12945
 2004-04-14 15:06:48 +00:00
John Criswell 0c654c6a4e Added code to verify that llvm.readio's pointer argument returns something 
that matches its return type.

Sorry these didn't get in yesterday.

Chris Lattner 0dc099c2b5 This is the real fix for Codegen/X86/2004-04-13-FPCMOV-Crash.llx which works 
even when the "optimization" I added before is turned off.  It generates this
extremely pointless code:

test:
        fld QWORD PTR [%ESP + 4]
        mov %AL, 0
        test %AL, %AL
        fcmove %ST(0), %ST(0)
        ret

Good thing the optimizer will have removed this before code generation
anyway.  :)

Chris Lattner 52acdaacc7 Temporarily hack in the intrinsics that John added. I expect him to finish up their addition, but in the meantime, the build should not be broken.

 2004-04-14 02:22:54 +00:00
John Criswell beded72a08 Added support for the llvm.readio and llvm.writeio intrinsics. 
On x86, memory operations occur in-order, so these are just lowered into
volatile loads and stores.

llvm-svn: 12936
 2004-04-13 22:13:14 +00:00
Chris Lattner 9042e381d8 Implement a small optimization, which papers over the problem in 
X86/2004-04-13-FPCMOV-Crash.llx

A more robust fix is to follow.

Chris Lattner e542c1c422 Remove spiff. Though it looked good, it was not really as spiffy as it seemed 
llvm-svn: 12927
 2004-04-13 20:58:42 +00:00
Chris Lattner 5613bcc258 Okay, spiff is completely incapable of handling files of nontrivial size. 
Here is a simple minimal program that does what we want.  Instead of taking
minutes to compare mesa's output, and crashing on binary files (like spiff
does), this take < .02s in the common case and doesn't crash.

Brian Gaeke 6f6e4b9f59 I don't think we have to have 4 extra allocated (but unused) bytes on the stack.

Chris Lattner c71b096672 Emit the immediate form of in/out when possible. 
Fix several bugs in the intrinsics:
  1. Make sure to copy the input registers before the instructions that use them
  2. Make sure to copy the value returned by 'in' out of EAX into the register
     it is supposed to be in.

This fixes assertions when using in/out and linear scan.
