2004-04-14Implement a FIXME: if we're going to insert a cast, we might as well onlyChris Lattner
insert it once! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12955 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-14Remove code to adjust the iterator for llvm.readio and llvm.writeio.John Criswell
The iterator is pointing at the next instruction which should not disappear when doing the load/store replacement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12954 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-14Fix typo.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12953 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-14This is a trivial tweak to the addrec insertion code: insert the incrementChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12952 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-14Add a TargetData to the PassManager regardless of the TargetMachine.Brian Gaeke
This should unbreak the Sparc JIT again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12949 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-14Remove the return type check for llvm.readio. This check is done for allJohn Criswell
functions and is not needed here. Simplify the pointer type check per Chris's suggestions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12945 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-14Added code to verify that llvm.readio's pointer argument returns somethingJohn Criswell
that matches its return type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12944 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-14Finish adding the llvm.readio and llvm.writeio intrinsics.John Criswell
Sorry these didn't get in yesterday. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12942 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-14ADd a trivial instcombine: load null -> nullChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12940 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-14This is the real fix for Codegen/X86/2004-04-13-FPCMOV-Crash.llx which worksChris Lattner
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. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12939 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-14Temporarily hack in the intrinsics that John added. I expect him to finish ↵Chris Lattner
up their addition, but in the meantime, the build should not be broken. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12938 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-13Added support for the llvm.readio and llvm.writeio intrinsics.John Criswell
On x86, memory operations occur in-order, so these are just lowered into volatile loads and stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12936 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-13Remove spiff. Though it looked good, it was not really as spiffy as it seemedChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12927 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-13Okay, spiff is completely incapable of handling files of nontrivial size.Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12926 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-13Emit the immediate form of in/out when possible.Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12896 91177308-0d34-0410-b5e6-96231b3b80d8
