* AArch64: add llc-based tests for previous commit.Tim Northover2013-07-252-2/+15
| | | | | | Better to have tests run even on non-AArch64 platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187128 91177308-0d34-0410-b5e6-96231b3b80d8
* AArch64: fix even more JIT failuresTim Northover2013-07-252-4/+4
| | | | | | | The last patch corrected some issues, but constant-pool entries had actual codegen bugs in the large memory model (which MCJIT uses). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187126 91177308-0d34-0410-b5e6-96231b3b80d8

* AArch64: don't mask off shift bits when processing JIT relocations.Tim Northover2013-07-251-4/+4
| | | | | | | This should actually make the MCJIT tests pass again on AArch64. I don't know how I missed their failure before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187120 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a bug in TableGen where the intrinsic function name recognizer could ↵Justin Holewinski2013-07-252-0/+53
| | | | | | | | | | | | | | | | | mis-identify names if one was a prefix substring of the other For two intrinsics 'llvm.nvvm.texsurf.handle' and 'llvm.nvvm.texsurf.handle.internal', TableGen was emitting matching code like: if (Name.startswith("llvm.nvvm.texsurf.handle")) ... if (Name.startswith("llvm.nvvm.texsurf.handle.internal")) ... We can never match "llvm.nvvm.texsurf.handle.internal" here because it will always be erroneously matched by the first condition. The fix is to sort the intrinsic names and emit them in reverse order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187119 91177308-0d34-0410-b5e6-96231b3b80d8

* [SystemZ] Rework compare and branch supportRichard Sandiford2013-07-256-62/+151
| | | | | | | | | | | | | | | Before the patch we took advantage of the fact that the compare and branch are glued together in the selection DAG and fused them together (where possible) while emitting them. This seemed to work well in practice. However, fusing the compare so early makes it harder to remove redundant compares in cases where CC already has a suitable value. This patch therefore uses the peephole analyzeCompare/optimizeCompareInstr pair of functions instead. No behavioral change intended, but it paves the way for a later patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187116 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | As with the stores, these instructions can trap when the condition is false, so they are only used for things like (cond ? x : *ptr). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187112 91177308-0d34-0410-b5e6-96231b3b80d8
* [SystemZ] Add STOC and STOCGRichard Sandiford2013-07-2514-53/+664
| | | | | | | | | These instructions are allowed to trap even if the condition is false, so for now they are only used for "*ptr = (cond ? x : *ptr)"-style constructs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187111 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info: improve the verifier to check field types.Manman Ren2013-07-2535-167/+217
| | | | | | | | | Make sure the context and type fields are MDNodes. We will generate verification errors if those fields are non-empty strings. Fix testing cases to make them pass the verifier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187106 91177308-0d34-0410-b5e6-96231b3b80d8
* Respect llvm.used in Internalize.Rafael Espindola2013-07-255-21/+69
| | | | | | | | | | | | | | | The language reference says that: "If a symbol appears in the @llvm.used list, then the compiler, assembler, and linker are required to treat the symbol as if there is a reference to the symbol that it cannot see" Since even the linker cannot see the reference, we must assume that the reference can be using the symbol table. For example, a user can add __attribute__((used)) to a debug helper function like dump and use it from a debugger. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187103 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | There's no need to specify a flag to omit frame pointer elimination on non-leaf nodes...(Honestly, I can't parse that option out.) Use the function attribute stuff instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187093 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a bug in IfConverter with nested predicates.Quentin Colombet2013-07-242-3/+62
| | | | | | | | | | | | | | | | | | | | Prior to this patch, IfConverter may widen the cases where a sequence of instructions were executed because of the way it uses nested predicates. This result in incorrect execution. For instance, Let A be a basic block that flows conditionally into B and B be a predicated block. B can be predicated with A.BrToBPredicate into A iff B.Predicate is less "permissive" than A.BrToBPredicate, i.e., iff A.BrToBPredicate subsumes B.Predicate. The IfConverter was checking the opposite: B.Predicate subsumes A.BrToBPredicate. <rdar://problem/14379453> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187071 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't leak when expanding response files.Rafael Espindola2013-07-241-17/+15
| | | | | | | | | | | | | | Before this patch we would strdup each argument. If one was a response file, we would replace it with the response file contents, leaking the original strdup result. We now don't strdup the originals and let StringSaver free any memory it allocated. This also saves a bit of malloc traffic when response files are not used. Leak found by the valgrind build bot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187042 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PR16687 where we were incorrectly promoting an alloca that hadChandler Carruth2013-07-242-12/+66
| | | | | | | | | | | | | | | | | | | | | | pending speculation for a phi node. The problem here is that we were using growth of the specluation set as an indicator of whether speculation would occur, and if the phi node is already in the set we don't see it grow. This is a symptom of the fact that this signal is a total hack. Unfortunately, I couldn't really come up with a non-hacky way of signaling that promotion remains valid *after* speculation occurs, such that we only speculate when all else looks good for promotion. In the end, I went with at least a much more explicit approach of doing the work of queuing inside the phi and select processing and setting a preposterously named flag to convey that we're in the special state of requiring speculating before promotion.

| | | | | | | | | | | | | | | | | | | | | Similar to ARM change r182800, dynamic linker will read bits/addends from the original object rather than from the object that might have been patched previously. For the purpose of relocations for MCJIT stubs on MIPS, we internally use otherwise unused MIPS relocations.
