* Submit the basic port of the rest of ARM constant islands code to Mips. Reed Kotler2013-11-04
| | | | | | | | | | | | | | | | | | | Two test cases are added which reflect the next level of functionality: constants getting moved to water areas that are out of range from the initial placement at the end of the function and basic blocks being split to create water when none exists that can be used. There is a bunch of this code that is not complete and has been marked with IN_PROGRESS. I will finish cleaning this all up during the next week or two and submit the rest of the test cases. I have elminated some code for dealing with inline assembly because to me it unecessarily complicates things and some of the newer features of llvm like function attributies and builtin assembler give me better tools to solve the alignment issues created there. Also, for Mips16 I even have the option of not doing constant islands in the present of inline assembler if I chose. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194019 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | normal IR (i.e. not intrinsics) Also corrected the definition of the intrinsics for these instructions (the result register is also the first operand), and added intrinsics for bsel and bseli to clang (they already existed in the backend). These four operations are mostly equivalent to bsel, and bseli (the difference is which operand is tied to the result). As a result some of the tests changed as described below. bitwise.ll: - bsel.v test adapted so that the mask is unknown at compile-time. This stops it emitting bmnzi.b instead of the intended bsel.v. - The bseli.b test now tests the right thing. Namely the case when one of the values is an uimm8, rather than when the condition is a uimm8 (which is covered by bmnzi.b) compare.ll: - bsel.v tests now (correctly) emits bmnz.v instead of bsel.v because this is the same operation (see MSA.txt). i8.ll - CHECK-DAG-ized test. - bmzi.b test now (correctly) emits equivalent bmnzi.b with swapped operands because this is the same operation (see MSA.txt). - bseli.b still emits bseli.b though because the immediate makes it distinguishable from bmnzi.b. vec.ll: - CHECK-DAG-ized test. - bmz.v tests now (correctly) emits bmnz.v with swapped operands (see MSA.txt). - bsel.v tests now (correctly) emits bmnz.v with swapped operands (see MSA.txt). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193693 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | not intrinsics) This required correcting the definition of the bins[lr]i intrinsics because the result is also the first operand. It also required removing the (arbitrary) check for 32-bit immediates in MipsSEDAGToDAGISel::selectVSplat(). Currently using binsli.d with 2 bits set in the mask doesn't select binsli.d because the constant is legalized into a ConstantPool. Similar things can happen with binsri.d with more than 10 bits set in the mask. The resulting code when this happens is correct but not optimal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193687 91177308-0d34-0410-b5e6-96231b3b80d8
* [mips][msa] Combine binsri-like DAG of AND and OR into equivalent VSELECTDaniel Sanders2013-10-30
| | | | | | | | | | | | | | | | | (or (and $a, $mask), (and $b, $inverse_mask)) => (vselect $mask, $a, $b). where $mask is a constant splat. This allows bitwise operations to make use of bsel. It's also a stepping stone towards matching bins[lr], and bins[lr]i from normal IR. Two sets of similar tests have been added in this commit. The bsel_* functions test the case where binsri cannot be used. The binsr_*_i functions will start to use the binsri instruction in the next commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193682 91177308-0d34-0410-b5e6-96231b3b80d8

* Make first substantial checkin of my port of ARM constant islands code to Mips.Reed Kotler2013-10-27
| | | | | | | | | | | | | | Before I just ported the shell of the pass. I've tried to keep everything nearly identical to the ARM version. I think it will be very easy to eventually merge these two and create a new more general pass that other targets can use. I have some improvements I would like to make to allow pools to be shared across functions and some other things. When I'm all done we can think about making a more general pass. More to be ported but the basic mechanism works now almost as good as gcc mips16. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193509 91177308-0d34-0410-b5e6-96231b3b80d8
