* Adding more assignment of ordering to SDNodes. This time in the "call" andBill Wendling2009-12-221-32/+66
| | | | | | generic copy functions. llvm-svn: 91872
* Fixed library dependencies between the X86 disassembler andSean Callanan2009-12-223-18/+5
| | | | | | X86 codegen that were causing circular symbol dependencies. llvm-svn: 91871

| | | | | | | | | | | | | | get things like this out of the disassembler: 0x100000ecb: callq -96 instead of: 0x100000ecb: callq 4294967200 rdar://7491123 llvm-svn: 91864
* Now add ordering to SDNodes created by the massive intrinsic lowering function.Bill Wendling2009-12-221-100/+183

* To make things interesting, I added MORE code to set the ordering ofBill Wendling2009-12-221-32/+387
| | | | | | SDNodes. This time in the load/store and limited-precision code. llvm-svn: 91860
* Changed slot index ranges for MachineBasicBlocks to be exclusive of endpoint.Lang Hames2009-12-227-34/+29
| | | | | | This fixes an in-place update bug where code inserted at the end of basic blocks may not be covered by existing intervals which were live across the entire block. It is also consistent with the way ranges are specified for live intervals. llvm-svn: 91859
* Add more plumbing to assign ordering to SDNodes. Have the "getValue" methodBill Wendling2009-12-211-59/+133
| | | | | | | assign the ordering when called. Combine some of the ordering assignments to keep things simple. llvm-svn: 91857
* Add suggested parentheses.Daniel Dunbar2009-12-211-4/+4
| | | | llvm-svn: 91853
* Add a fastpath to Load GVN to special case when we have exactly one dominatingChris Lattner2009-12-211-2/+10
| | | | | | | | | | | load to avoid even messing around with SSAUpdate at all. In this case (which is very common, we can just use the input value directly). This speeds up GVN time on gcc.c-torture/20001226-1.c from 36.4s to 16.3s, which still isn't great, but substantially better and this is a simple speedup that applies to lots of different cases. llvm-svn: 91851
* More ordering plumbing. This time for GEP. I need to remember to assignBill Wendling2009-12-211-4/+32

* Assign ordering to more instructions. Incremental check-in.Bill Wendling2009-12-211-57/+156

* - Add a bit more plumbing assigning an order to SDNodes.Bill Wendling2009-12-213-9/+35
| | | | | | - Modify the "dump" method to emit the order of an SDNode. llvm-svn: 91845
* Fix a bug in !subst where TableGen would go and resubstitute text it hadDavid Greene2009-12-212-1/+18
| | | | | | | just substituted. This could cause infinite looping in certain pathological cases. llvm-svn: 91843
* Remove uber-gross hack. The define _snprintf to snprintf is invalid due to ↵Anton Korobeynikov2009-12-211-3/+0
| | | | | | two reasons: 1. Accroding to C++ standard snprintf should be available in std namespace (and __gnu_cxx in case of GCC to). Such ifdef will change all snprintf's to _snprintf's, but won't bring snprintf to all necessary namespaces. Thus e.g. any locale-using code on mingw will yield an error (include this file + string to see the result) 2. MSVCRT's _snprintf does not comply with C99 standard. Standard one is snprintf. llvm-svn: 91842

* Remove special-case SROA optimization of variable indexes to one-element andBob Wilson2009-12-211-141/+30
| | | | | | | | two-element arrays. After restructuring the SROA code, it was not safe to do this without adding more checking. It is not clear that this special-case has really been useful, and removing this simplifies the code quite a bit. llvm-svn: 91828
* XFAIL these tests on powerpc, under the assumption that no one cares. If you ↵Daniel Dunbar2009-12-212-0/+2

* Fix setting and default setting of code model for jit. Do thisEric Christopher2009-12-215-16/+58
| | | | | | | | | | by allowing backends to override routines that will default the JIT and Static code generation to an appropriate code model for the architecture. Should fix PR 5773. llvm-svn: 91824

* fix PR5837 by having SSAUpdate reuse phi nodes for theChris Lattner2009-12-212-1/+58
| | | | | | | | | | 'GetValueInMiddleOfBlock' case, instead of inserting duplicates. A similar fix is almost certainly needed by the machine-level SSAUpdate implementation. llvm-svn: 91820

| | | | | | | | | implement some optimizations for MIN(MIN()) and MAX(MAX()) and MIN(MAX()) etc. This substantially improves the code in PR5822 but doesn't kick in much elsewhere. 2 max's were optimized in pairlocalalign and one in smg2000. llvm-svn: 91814

* enhance x-(-A) -> x+A to preserve NUW/NSW.Chris Lattner2009-12-212-11/+60
| | | | | | | | | | | Use the presence of NSW/NUW to fold "icmp (x+cst), x" to a constant in cases where it would otherwise be undefined behavior. Surprisingly (to me at least), this triggers hundreds of the times in a few benchmarks: lencode, ldecode, and 466.h264ref seem to *really* like this. llvm-svn: 91812
