* ARM: implement allowTruncateForTailCallTim Northover2013-08-063-0/+129

* LLVM Interpreter: fixed bug 16694Elena Demikhovsky2013-08-061-52/+137
| | | | | | | | | | | | | | fix for: Bug 16694 - ExecutionEngine/test-interp-vec-loadstore.ll failing on powerpc-darwin8 (http://llvm.org/bugs/show_bug.cgi?id=16694) The ExecutionEngine/test-interp-vec-loadstore.ll test has been failing on powerpc-darwin8 (on other platforms it passed) the reason of fail was wrong output by printf. this output is checked by FileCheck, but on little-endian powerpc the output numeric data were printed inside out and FileCheck reported fail. the printfs have been replaced by checking data inside test and numeric output has been replaced by the text output like : "int test passed, float test passed". The text output is checked by FileCheck. the dependency on data layout has been removed. done by Yuri Veselov (Intel) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187791 91177308-0d34-0410-b5e6-96231b3b80d8

* Refactor isInTailCallPosition handlingTim Northover2013-08-069-134/+484
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change came about primarily because of two issues in the existing code. Niether of: define i64 @test1(i64 %val) { %in = trunc i64 %val to i32 tail call i32 @ret32(i32 returned %in) ret i64 %val } define i64 @test2(i64 %val) { tail call i32 @ret32(i32 returned undef) ret i32 42 } should be tail calls, and the function sameNoopInput is responsible. The main problem is that it is completely symmetric in the "tail call" and "ret" value, but in reality different things are allowed on each side. For these cases: 1. Any truncation should lead to a larger value being generated by "tail call" than needed by "ret". 2. Undef should only be allowed as a source for ret, not as a result of the call. Along the way I noticed that a mismatch between what this function treats as a valid truncation and what the backends see can lead to invalid calls as well (see x86-32 test case). This patch refactors the code so that instead of being based primarily on values which it recurses into when necessary, it starts by inspecting the type and considers each fundamental slot that the backend will see in turn. For example, given a pathological function that returned {{}, {{}, i32, {}}, i32} we would consider each "real" i32 in turn, and ask if it passes through unchanged. This is much closer to what the backend sees as a result of ComputeValueVTs. Aside from the bug fixes, this eliminates the recursion that's going on and, I believe, makes the bulk of the code significantly easier to understand. The trade-off is the nasty iterators needed to find the real types inside a returned value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187787 91177308-0d34-0410-b5e6-96231b3b80d8

* R600: Implement TargetLowering::getVectorIdxTy()Tom Stellard2013-08-053-5/+14
| | | | | | | We use MVT::i32 for the vector index type, because we use 32-bit operations to caculate offsets when dynamically indexing vectors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187749 91177308-0d34-0410-b5e6-96231b3b80d8
* TargetLowering: Add getVectorIdxTy() function v2Tom Stellard2013-08-059-77/+105
| | | | | | | | | | | | | | | | | | | | | This virtual function can be implemented by targets to specify the type to use for the index operand of INSERT_VECTOR_ELT, EXTRACT_VECTOR_ELT, INSERT_SUBVECTOR, EXTRACT_SUBVECTOR. The default implementation returns the result from TargetLowering::getPointerTy() The previous code was using TargetLowering::getPointerTy() for vector indices, because this is guaranteed to be legal on all targets. However, using TargetLowering::getPointerTy() can be a problem for targets with pointer sizes that differ across address spaces. On such targets, when vectors need to be loaded or stored to an address space other than the default 'zero' address space (which is the address space assumed by TargetLowering::getPointerTy()), having an index that is a different size than the pointer can lead to inefficient pointer calculations, (e.g. 64-bit adds for a 32-bit address space). There is no intended functionality change with this patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187748 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce an optimisation for special case lists with large numbers of ↵Peter Collingbourne2013-08-052-14/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | literal entries. Our internal regex implementation does not cope with large numbers of anchors very efficiently. Given a ~3600-entry special case list, regex compilation can take on the order of seconds. This patch solves the problem for the special case of patterns matching literal global names (i.e. patterns with no regex metacharacters). Rather than forming regexes from literal global name patterns, add them to a StringSet which is checked before matching against the regex. This reduces regex compilation time by an order of roughly thousands when reading the aforementioned special case list, according to a completely unscientific study. No test cases. I figure that any new tests for this code should check that regex metacharacters are properly recognised. However, I could not find any documentation which documents the fact that the syntax of global names in special case lists is based on regexes. The extent to which regex syntax is supported in special case lists should probably be decided on/documented before writing tests.

* [SystemZ] Use BRCT and BRCTG to eliminate add-&-compare sequencesRichard Sandiford2013-08-058-18/+419
| | | | | | | | | | | | | | | | | This patch just uses a peephole test for "add; compare; branch" sequences within a single block. The IR optimizers already convert loops to decrement-and-branch-on-nonzero form in some cases, so even this simplistic test triggers many times during a clang bootstrap and projects/test-suite run. It looks like there are still cases where we need to more strongly prefer branches on nonzero though. E.g. I saw a case where a loop that started out with a check for 0 ended up with a check for -1. I'll try to look at that sometime. I ended up adding the Reference class because MachineInstr::readsRegister() doesn't check for subregisters (by design, as far as I could tell). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187723 91177308-0d34-0410-b5e6-96231b3b80d8
