2010-03-26Add N2RegVShLFrm and N2RegVShRFrm formats so that the disassembler can easilyJohnny Chen
dispatch to the appropriate routines to handle the different interpretations of the shift amount encoded in the imm6 field. The Vd, Vm fields are interpreted the same between the two, though. See, for example, A8.6.367 VQSHL, VQSHLU (immediate) for N2RegVShLFrm format and A8.6.368 VQSHRN, VQSHRUN for N2RegVShRFrm format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99590 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25llvm-mc: Add a -mc-relax-all option, which relaxes every fixup. We always needDaniel Dunbar
exactly two passes in that case, and don't ever need to recompute any layout, so this is a nice baseline for relaxation performance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99563 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25MC: Stop restarting layout on every relaxation.Daniel Dunbar
- Still O(N^2), just a faster form, and now its the MCAsmLayout's fault. On the .s I am tuning against (combine.s from 403.gcc): -- ddunbar@lordcrumb:MC$ diff stats-before.txt stats-after.txt 5,10c5,10 < 1728 assembler - Number of assembler layout and relaxation steps < 7707 assembler - Number of emitted assembler fragments < 120588 assembler - Number of emitted object file bytes < 2233448 assembler - Number of evaluated fixups < 1727 assembler - Number of relaxed instructions < 6723845 mcexpr - Number of MCExpr evaluations --- > 3 assembler - Number of assembler layout and relaxation steps > 7707 assembler - Number of emitted assembler fragments > 120588 assembler - Number of emitted object file bytes > 14796 assembler - Number of evaluated fixups > 1727 assembler - Number of relaxed instructions > 67889 mcexpr - Number of MCExpr evaluations -- Feel free to LOL at the -before numbers, if you like. I am a little surprised we make more than 2 relaxation passes. It's pretty trivial for us to do relaxation out-of-order if that would give a speedup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99543 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25Teach TableGen to understand X.Y notation in the TSFlagsFields strings.Jakob Stoklund Olesen
Remove much horribleness from X86InstrFormats as a result. Similar simplifications are probably possible for other targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99539 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-25fix a valgrind error on copy-constructor-synthesis.cpp, which is caused whenChris Lattner
the custom insertion hook deletes the instruction, then we try to set dead flags on it. Neither the code that I added nor the code that was there before was safe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99538 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain ↵Jakob Stoklund Olesen
crossings. On Nehalem and newer CPUs there is a 2 cycle latency penalty on using a register in a different domain than where it was defined. Some instructions have equvivalents for different domains, like por/orps/orpd. The SSEDomainFix pass tries to minimize the number of domain crossings by changing between equvivalent opcodes where possible. This is a work in progress, in particular the pass doesn't do anything yet. SSE instructions are tagged with their execution domain in TableGen using the last two bits of TSFlags. Note that not all instructions are tagged correctly. Life just isn't that simple. The SSE execution domain issue is very similar to the ARM NEON/VFP pipeline issue handled by NEONMoveFixPass. This pass may become target independent to handle both. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99524 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-25Added a new instruction class NVDupLane to be inherited by VDUPLND and VDUPLNQ,Johnny Chen
instead of the current N2V. Format of NVDupLane instances are set to NEONFrm currently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99518 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25Fixed spurious warning problem noticed by Daniel Dunbar. The configure scriptJohn Criswell
now configures prerequisite projects individually but also ignores them in the big project switch statement to avoid the incorrect warning. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99506 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25Change tblgen to emit FOOISD opcode names as twoChris Lattner
bytes instead of one byte. This is important because we're running up to too many opcodes to fit in a byte and it is aggrevated by FIRST_TARGET_MEMORY_OPCODE making the numbering sparse. This just bites the bullet and bloats out the table. In practice, this increases the size of the x86 isel table from 74.5K to 76K. I think we'll cope :) This fixes rdar://7791648 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99494 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25Fix evil TableGen bug in template parameters with defaults.Jakob Stoklund Olesen
If a TableGen class has an initializer expression containing an X.Y subexpression, AND X depends on template parameters, AND those template parameters have defaults, AND some parameters with defaults are beyond position 1, THEN parts of the initializer expression are evaluated prematurely with the default values when the first explicit template parameter is substituted, before the remaining explicit template parameters have been substituted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99492 91177308-0d34-0410-b5e6-96231b3b80d8
