* Change the linkage of these global values to 'internal'.Bill Wendling2013-08-062-6/+9
| | | | | | | | | | | | | | | | | | | The globals being generated here were given the 'private' linkage type. However, this caused them to end up in different sections with the wrong prefix. E.g., they would be in the __TEXT,__const section with an 'L' prefix instead of an 'l' (lowercase ell) prefix. The problem is that the linker will eat a literal label with 'L'. If a weak symbol is then placed into the __TEXT,__const section near that literal, then it cannot distinguish between the literal and the weak symbol. Part of the problems here was introduced because the address sanitizer converted some C strings into constant initializers with trailing nuls. (Thus putting them in the __const section with the wrong prefix.) The others were variables that the address sanitizer created but simply had the wrong linkage type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187827 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info Finder|Verifier: handle DbgLoc attached to instructions.Manman Ren2013-08-0617-50/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also remove checking of llvm.dbg.sp since it is not used in generating dwarf. Current state of Finder: DebugInfoFinder tries to list all debug info MDNodes used in a module. To list debug info MDNodes used by an instruction, DebugInfoFinder provides processDeclare, processValue and processLocation to handle DbgDeclareInst, DbgValueInst and DbgLoc attached to instructions. processModule will go through all DICompileUnits in llvm.dbg.cu and list debug info MDNodes used by the CUs. TODO: 1> Finder has a list of CUs, SPs, Types, Scopes and global variables. We need to add a list of variables that are used by DbgDeclareInst and DbgValueInst. 2> MDString fields should be null or isa<MDString> and MDNode fields should be null or isa<MDNode>. We currently use empty string or int 0 to represent null. 3> Go though Verify functions and make sure that they check field types. 4> Clean up existing testing cases to remove llvm.dbg.sp and make sure each testing case has a llvm.dbg.cu. Re-apply r187609 with fix to pass ocaml binding. vmcore.ml generates a debug location with scope being metadata !{}, in verifier we treat this as a null scope. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187812 91177308-0d34-0410-b5e6-96231b3b80d8

* 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

* 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
