2010-02-24Added for disassembly VST1 (multiple single elements) which stores elements toJohnny Chen
memory from three or four registers and VST2 (multiple two-element structures) which stores to memory from two double-spaced registers. A8.6.391 & A8.6.393 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97018 91177308-0d34-0410-b5e6-96231b3b80d8

Machine instruction selection is much happier when operands are in virtual registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97012 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Re-apply 96540 and 96556 with fixes.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97011 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Add an argument to PHITranslateValue to specify the DominatorTree. If thisBob Wilson
argument is non-null, pass it along to PHITranslateSubExpr so that it can prefer using existing values that dominate the PredBB, instead of just blindly picking the first equivalent value that it finds on a uselist. Also when the DominatorTree is specified, have PHITranslateValue filter out any result that does not dominate the PredBB. This is basically just refactoring the check that used to be in GetAvailablePHITranslatedSubExpr and also in GVN. Despite my initial expectations, this change does not affect the results of GVN for any testcases that I could find, but it should help compile time. Before this change, if PHITranslateSubExpr picked a value that does not dominate, PHITranslateWithInsertion would then insert a new value, which GVN would later determine to be redundant and would replace. By picking a good value to begin with, we save GVN the extra work of inserting and then replacing a new value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97010 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96995 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23Keep track of phi join registers explicitly in LiveVariables.Jakob Stoklund Olesen
Previously, LiveIntervalAnalysis would infer phi joins by looking for multiply defined registers. That doesn't work if the phi join is implicitly defined in all but one of the predecessors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96994 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23This is the second patch to allow x86 code to be aligned with optimal nops.Kevin Enderby
With the compiler changed to use EmitCodeAlignment() it does change the functionality. But X86 assembly code assembled with llvm-mc does not change its output. For that we will eventually change the assembler frontend to detect a '.align x, 0x90' when used in a section that 'hasInstructions' and use EmitCodeAlignment, but will wait until we have better target hooks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96988 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23Added for disassembly VLD1 (multiple single elements) which loads memory intoJohnny Chen
three or four registers and VLD2 (multiple two-element structures) which loads memory into two double-spaced registers. A8.6.307 & A8.6.310 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96980 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23no need to override IsLegalToFold, the base implementationChris Lattner

2010-02-23fix a bug in findNonImmUse (used by IsLegalToFold) where nodes withChris Lattner
no id's would cause early exit allowing IsLegalToFold to return true instead of false, producing a cyclic dag. This was striking the new isel because it isn't using SelectNodeTo yet, which theoretically is just an optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96972 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23Adding the MicroBlaze backend.Wesley Peck
The MicroBlaze is a highly configurable 32-bit soft-microprocessor for use on Xilinx FPGAs. For more information see: http://www.xilinx.com/tools/microblaze.htm http://en.wikipedia.org/wiki/MicroBlaze The current LLVM MicroBlaze backend generates assembly which can be compiled using the an appropriate binutils assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96969 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23This is the first patch to put the needed bits in place to eventually allow codeKevin Enderby
to be aligned with optimal nops. This patch does not change any functionality and when the compiler is changed to use EmitCodeAlignment() it should also not change the resulting output. Once the compiler change is made and everything looks good the next patch with the table of optimal X86 nops will be added to WriteNopData() changing the output. There are many FIXMEs in this patch which will be removed when we have better target hooks (coming soon I hear). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96963 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23Remove the code which constant-folded ptrtoint(inttoptr(x)+c) toDan Gohman
getelementptr. Despite only doing so in the case where x is a known array object and c can be converted to an index within range, this could still be invalid if c is actually the address of an object allocated outside of LLVM. Also, SCEVExpander, the original motivation for this code, has since been improved to avoid inttoptr+ptroint in more cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96950 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23Modified examples Makefile to only build the ExceptionDemo example for Garrison Venn
x86 and x86_64 on UNIX systems. Only OS X 10.6.2 (x86_64) and 32bit CentOS 5.2 with gcc 4.1.2 were tested. ARM UNIX build triggered failure motivating this modification, as it seems that the ARM ABI does not support _Unwind_GetIP(...), _Unwind_SetGR(...), and _Unwind_SetIP(...). From doing a quick browse of: http://infocenter.arm.com/help/topic/com.arm.doc.ihi0038a/IHI0038A_ehabi.pdf, it seems as if all other exception related apis are supported. Looks like the port can be done to ARM.

2010-02-23Initial configure support for using Clang as the LLVM capable compiler.Daniel Dunbar
Comes in two parts: 1. Use --with-clang=path/to/clang/compiler to select an installed clang, or --with-built-clang to have the makefiles use the clang which will be built as the LLVM capable compiler. If neither is given, --with-built-clang will be used if the Clang sources are checked out into the standard location (tools/clang). 2. Use --with-llvmcc={llvm-gcc,clang,none} to specify which LLVM capable compiler to use. If not given, then llvm-gcc will be used if available, otherwise Clang. Makefile support still to come. Eric, Doug, Chris, seem reasonable? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96934 91177308-0d34-0410-b5e6-96231b3b80d8
