* [docs] [tblgen] clarify that code fragments are just string literalsSean Silva2014-02-09
| | | | | | | | Fun fact: looking at the TableGen code (around TGParser.cpp:1166), the only difference in handling is that adjacent regular string literals are concatenated in the parser. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201035 91177308-0d34-0410-b5e6-96231b3b80d8
* [docs] [tblgen] There is no "code" type.Sean Silva2014-02-09

* [docs] TableGen easter egg: Multiline string literalsSean Silva2014-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | They're called code fragments, but they are really multiline string literals. Just spotted this usage in a patch by Aaron using "code fragments" for holding documentation text. I remember someone bemoaning the lack of multiline string literals in TableGen, so I'm explicitly documenting that code fragments are multiline string literals. Let it be known that any use case needing multiline string literals in TableGen (such as descriptions of options, or whatnot) can use use code fragments (instead of C-style string concatenation or exceedingly long lines). E.g. class Bar<int n>; class Baz<int n>; class Doc<string desc> { string Desc = desc; } def Foo : Bar<1>, Baz<3>, Doc<[{ This Foo is a Bar, and also a Baz. It can take 3 values: * Qux * Quux * Quuux }]>; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201033 91177308-0d34-0410-b5e6-96231b3b80d8

* LoopVectorizer: Keep track of conditional store basic blocksArnold Schwaighofer2014-02-08
| | | | | | | | | | | | | Before conditional store vectorization/unrolling we had only one vectorized/unrolled basic block. After adding support for conditional store vectorization this will not only be one block but multiple basic blocks. The last block would have the back-edge. I updated the code to use a vector of basic blocks instead of a single basic block and fixed the users to use the last entry in this vector. But, I forgot to add the basic blocks to this vector!

* LLVM-1163: AAPCS-VFP violation when CPRC allocated to stackOliver Stannard2014-02-07
| | | | | | | | | | | | | | According to the AAPCS, when a CPRC is allocated to the stack, all other VFP registers should be marked as unavailable. I have also modified the rules for allocating non-CPRCs to the stack, to make it more explicit that all GPRs must be made unavailable. I cannot think of a case where the old version would produce incorrect answers, so there is no test for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200970 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | mode. Basically the idea is to transform code like this: %idx = add nsw i32 %a, 1 %sextidx = sext i32 %idx to i64 %gep = gep i8* %myArray, i64 %sextidx load i8* %gep Into: %sexta = sext i32 %a to i64 %idx = add nsw i64 %sexta, 1 %gep = gep i8* %myArray, i64 %idx load i8* %gep That way the computation can be folded into the addressing mode. This transformation is done as part of the addressing mode matcher. If the matching fails (not profitable, addressing mode not legal, etc.), the matcher will revert the related promotions. <rdar://problem/15519855> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200947 91177308-0d34-0410-b5e6-96231b3b80d8
* Track register pressure a bit more carefully (weird corner case).Andrew Trick2014-02-06
| | | | | | | | | | | | | | | | This solves a problem where a def machine operand has no uses but has not been marked dead. In this case, the initial RP analysis was being extra precise and determining from LiveIntervals the the register was actually dead. This caused us to omit the register from the RP tracker's block live out. That's all good, but the per-instruction summary still accounted for it as a valid def. This could cause an assertion in the tracker later when we underflow pressure. This is from a bug report on an out-of-tree target. It is not reproducible on well-behaved targets. I'm just making an obvious fix without unit test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200941 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove const_cast for STI when parsing inline asmDavid Peixotto2014-02-06
| | | | | | | | | | | | | | | | | | | | | | In a previous commit (r199818) we added a const_cast to an existing subtarget info instead of creating a new one so that we could reuse it when creating the TargetAsmParser for parsing inline assembly. This cast was necessary because we needed to reuse the existing STI to avoid generating incorrect code when the inline asm contained mode-switching directives (e.g. .code 16). The root cause of the failure was that there was an implicit sharing of the STI between the parser and the MCCodeEmitter. To fix a different but related issue, we now explicitly pass the STI to the MCCodeEmitter (see commits r200345-r200351). The const_cast is no longer necessary and we can now create a fresh STI for the inline asm parser to use.

* X86: add costs for 64-bit vector ext/trunc & rebalanceTim Northover2014-02-06
| | | | | | | | | | | | | | | | | | | | The most important part of this is probably adding any cost at all for operations like zext <8 x i8> to <8 x i32>. Before they were being recorded as extremely costly (24, I believe) which made LLVM fall back on a 4-wide vectorisation of a loop. It also rebalances the values for sext, zext and trunc. Lacking any other sane metric that might work across CPU microarchitectures I went for instructions. This seems to be in reasonable accord with the rest of the table (sitofp, ...) though no doubt at least one value is sub-optimal for some bizarre reason. Finally, separate AVX and AVX2 values are provided where appropriate. The CodeGen is quite different in many cases. rdar://problem/15981990 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200928 91177308-0d34-0410-b5e6-96231b3b80d8
