* Tidy up spacing in some tablegen outputs.Craig Topper2012-04-032-11/+9
| | | | llvm-svn: 153937
* Add support for AVX enhanced comparison predicates. Patch from Kay Tiong Khoo.Craig Topper2012-04-032-0/+3
| | | | llvm-svn: 153935
* As Eric pointed out, even a Debug build should be equal. Leave the flag that ↵Bill Wendling2012-04-031-10/+8
| | | | | | can turn off comparisons though. llvm-svn: 153927
* Cleanup set_union usage. The same thing but a bit cleaner now.Andrew Trick2012-04-031-1/+1
| | | | llvm-svn: 153922
* Use std::set_union instead of nasty custom code.Andrew Trick2012-04-031-13/+3
| | | | | | | I just noticed Jakob's examples of the proper application of std::set... routines. llvm-svn: 153918
* Compare the .o files only for release builds. Add an option to bypass the ↵Bill Wendling2012-04-021-16/+26
| | | | | | comparison altogether. llvm-svn: 153909
* Second part for the 153874 oneSilviu Baranga2012-04-021-3/+3
| | | | llvm-svn: 153875
* Emit the asm writer's mnemonic table with SequenceToOffsetTable.Benjamin Kramer2012-04-021-6/+21
| | | | | | This way we can get AVX v-prefixed instructions tail merged with the normal insns. llvm-svn: 153869
* Reorder fields in MatchEntry and OperandMatchEntry to reduce padding. A bit ↵Craig Topper2012-04-021-24/+25
| | | | | | tricky due to the target specific sizes for some of the fields so the ordering is only optimal for the targets in the tree. llvm-svn: 153865
* Remove getInstructionName from MCInstPrinter implementations in favor of ↵Craig Topper2012-04-022-50/+0
| | | | | | using the instruction name table from MCInstrInfo. Reduces static data in the InstPrinter implementations. llvm-svn: 153863
* Use SequenceToOffsetTable to generate instruction name table for AsmWriter.Craig Topper2012-04-021-25/+27
| | | | llvm-svn: 153857
* Use SequenceToOffsetTable to create instruction name table. Saves space ↵Craig Topper2012-04-011-9/+16
| | | | | | particularly on X86 where AVX instructions just add a 'v' to the front of other instructions. llvm-svn: 153841
* Emit the LLVM<->DWARF register mapping as a sorted table and use binary ↵Benjamin Kramer2012-04-012-43/+146
| | | | | | | | | | | | | | | search to do the lookup. This also avoids emitting the information twice, which led to code bloat. On i386-linux-Release+Asserts with all targets built this change shaves a whopping 1.3 MB off clang. The number is probably exaggerated by recent inliner changes but the methods were already enormous with the old inline cost computation. The DWARF reg -> LLVM reg mapping doesn't seem to have holes in it, so it could be a simple lookup table. I didn't implement that optimization yet to avoid potentially changing functionality. There is still some duplication both in tablegen and the generated code that should be cleaned up eventually. llvm-svn: 153837

* Introduce Register Units: Give each leaf register a number.Andrew Trick2012-03-312-0/+60
| | | | | | | | First small step toward modeling multi-register multi-pressure. In the future, register units can also be used to model liveness and aliasing. llvm-svn: 153794
* Rip out emission of the regIsInRegClass function for the asm printer.Benjamin Kramer2012-03-302-68/+3
| | | | | | It's slow, bloated and completely redundant with MCRegisterClass::contains. llvm-svn: 153782
* Use SequenceToOffsetTable in emitRegisterNameString.Jakob Stoklund Olesen2012-03-302-8/+28
| | | | | | This allows suffix sharing in register names. (AX is a suffix of EAX). llvm-svn: 153777
* Reapply 153764 and 153761 with a fix.Jakob Stoklund Olesen2012-03-302-103/+80
| | | | | | | | | Use an explicit comparator instead of the default. The sets are sorted, but not using the default comparator. Hopefully, this will unbreak the Linux builders. llvm-svn: 153772
* Revert 153764 and 153761. They broke a --enable-optimized --enable-assertionsRafael Espindola2012-03-302-79/+103
| | | | | | --enable-expensive-checks build. llvm-svn: 153771
* Compress SimpleValueType lists by sharing.Jakob Stoklund Olesen2012-03-302-22/+17
| | | | | | Many register classes have the same value types. Share the table space. llvm-svn: 153764
* Compress register lists by sharing suffixes.Jakob Stoklund Olesen2012-03-301-81/+62
| | | | | | | | TableGen emits lists of sub-registers, super-registers, and overlaps. Put them all in a single table and use a SequenceToOffsetTable to share suffixes. llvm-svn: 153761
* Add a SequenceToOffsetTable to TableGen.Jakob Stoklund Olesen2012-03-301-0/+123
| | | | | | | | This is similar to the StringToOffsetTable we use to produce string tables, but it can be used for other sequences than strings, and it eliminates entries for suffixes. llvm-svn: 153760
* Add more constness to CodeGenRegisters.Jakob Stoklund Olesen2012-03-293-7/+7
| | | | llvm-svn: 153667
* Spill DPair registers, not just QPR.Jakob Stoklund Olesen2012-03-281-0/+1
| | | | | | | | | The arm_neon intrinsics can create virtual registers from the DPair register class which allows both even-odd and odd-even D-register pairs. This fixes PR12389. llvm-svn: 153603
* fix a failure path to print the right thing, part of PR12357Chris Lattner2012-03-261-1/+1

* Fix lit failure on cmake-clang-x64_64-linux bot, apparently due to its havingEli Bendersky2012-03-251-1/+4
| | | | | | a very (*very*) old version of Python (2.4?) llvm-svn: 153409
* Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnuEli Bendersky2012-03-251-0/+6
| | | | | | | | | | | | | | * Removed test/lib/llvm.exp - it is no longer needed * Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files left in the test suite so this code is no longer required. test/lit.cfg is now much shorter and clearer * Removed a lot of duplicate code in lit.local.cfg files that need access to the root configuration, by adding a "root" attribute to the TestingConfig object. This attribute is dynamically computed to provide the same information as was previously provided by the custom getRoot functions. * Documented the config.root attribute in docs/CommandGuide/lit.pod llvm-svn: 153408
* Include cstdio in a few place that depended on getting it transitively ↵Benjamin Kramer2012-03-232-1/+3

* Remove the C backend.Eric Christopher2012-03-233-4/+2
| | | | llvm-svn: 153307
* Add a ${pathsep} variable to lit that expands to : (or ; on win32).Nico Weber2012-03-211-0/+1
| | | | | | | | This is in braces so that it doesn't conflict with the existing %p. It uses braces instead of parens because parens would have to be regex-escaped. llvm-svn: 153213
* lit/TestRunner.py: [Win32] Rework WinWaitReleased() again! "win32file" from ↵NAKAMURA Takumi2012-03-211-28/+41
| | | | | | | | | | | Python Win32 Extensions. We can simply confirm the handle released to open it with EXCLUSIVE. Attempting renaming was bad. Disable win32file at ImportError. Thanks to Francois to let me know. FIXME: Could we report warning or notification if win32file were not found? llvm-svn: 153172
* Reserve number of MI operands to accom,odate complex patterns.Evan Cheng2012-03-201-1/+4
| | | | llvm-svn: 153125
* Revert r152915. Chapuni's WinWaitReleased refactoring: It doesn't work for meFrancois Pichet2012-03-161-12/+19
| | | | llvm-svn: 152958
* lit/TestRunner.py: [Win32] Check all opened_files[] released, rather than ↵NAKAMURA Takumi2012-03-161-9/+8
| | | | | | | | | | | | | (obsoleted) written_files[]. In previous case, RUN: foo -o %t RUN: FileCheck < %t RUN: bar -o %t 2nd read handle might prevent manipulation of 3rd %t in bar, to remove and rename. llvm-svn: 152916

* More const-correcting of FixedLenDecoderEmitter.Craig Topper2012-03-161-13/+17

* Const-correct the FixedLenDecoderEmitter. Pass a few things by const ↵Craig Topper2012-03-162-57/+62

* Remove unused field NumVariable from Filter class. Even it was needed the ↵Craig Topper2012-03-161-9/+3

* Make MnemonicTable const again. That part of r152202 was OK.Jakob Stoklund Olesen2012-03-151-4/+4
| | | | llvm-svn: 152840
* Don't assume all mnemonics fit in 64k.Jakob Stoklund Olesen2012-03-151-2/+2
| | | | | | | We currently assume that all targets have less than 64k opcodes. We shouldn't limit it further. llvm-svn: 152833
* Revert r152202: "Use uint16_t to store InstrNameIndices in MCInstrInfo."Jakob Stoklund Olesen2012-03-154-28/+16
| | | | | | | | We cannot limit the concatenated instruction names to 64K. ARM is already at 32K, and it is easy to imagine a target with more instructions. llvm-svn: 152817
* Revert r152105: "Use uint16_t to store indices into string table"Jakob Stoklund Olesen2012-03-151-5/+5
| | | | | | | | | | | This patch limited the concatenated register names to 64K which meant that the total number of registers was many times less than 64K. If any compilers actually enforce the 64K limit on string literals, and it turns out to be a problem, we should fix that problem by not using long string literals. llvm-svn: 152816
