* Add TargetLowering::prepareVolatileOrAtomicLoadRichard Sandiford2013-12-10
| | | | | | | | | | | | | | | | | | One unusual feature of the z architecture is that the result of a previous load can be reused indefinitely for subsequent loads, even if a cache-coherent store to that location is performed by another CPU. A special serializing instruction must be used if you want to force a load to be reattempted. Since volatile loads are not supposed to be omitted in this way, we should insert a serializing instruction before each such load. The same goes for atomic loads. The patch implements this at the IR->DAG boundary, in a similar way to atomic fences. It is a no-op for targets other than SystemZ. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196906 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert "Fix miscompile of MS inline assembly with stack realignment"Reid Kleckner2013-12-10
| | | | | | | This reverts commit r196876. Its tests failed on the bots, so I'll figure it out tomorrow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196879 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix miscompile of MS inline assembly with stack realignmentReid Kleckner2013-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | For stack frames requiring realignment, three pointers may be needed: - ebp to address incoming arguments - esi (could be any callee-saved register) to address locals - esp to address outgoing arguments We would use esi unconditionally without verifying that it did not conflict with inline assembly. This change doesn't do the verification, it simply emits a fatal error on functions that use stack realignment, dynamic SP adjustments, and inline assembly. Because stack realignment is common on Windows, we also no longer assume that MS inline assembly clobbers esp. Instead, we analyze the inline instructions for implicit definitions and check if esp is there. If so, we require the use of a base pointer and consider it in the condition above. Mostly fixes PR16830, but we could try harder to find a non-conflicting base pointer.

* Fix a crash that occurs when PWD is invalid.Andrew Trick2013-12-10
| | | | | | | | | | | | | | | | | | | | MCJIT needs to be able to run in hostile environments, even when PWD is invalid. There's no need to crash MCJIT in this case. The obvious fix is to simply leave MCContext's CompilationDir empty when PWD can't be determined. This way, MCJIT clients, and other clients that link with LLVM don’t need a valid working directory. If we do want to guarantee valid CompilationDir, that should be done only for clients of getCompilationDir(). This is as simple as checking for an empty string. The only current use of getCompilationDir is EmitGenDwarfInfo, which won’t conceivably run with an invalid working dir. However, in the purely hypothetically and untestable case that this happens, the AT_comp_dir will be omitted from the compilation_unit DIE. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196874 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-cov: Added -a option for block data.Yuchen Wu2013-12-10
| | | | | | | | | | | | | | | Similar to gcov, llvm-cov will now print out the block count at the end of each block. Multiple blocks can end on the same line. One computational difference is by using -a, llvm-cov will no longer simply add the block counts together to form a line count. Instead, it will take the maximum of the block counts on that line. This has a similar effect to what gcov does, but generates more correct counts in certain scenarios. Also updated tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196856 91177308-0d34-0410-b5e6-96231b3b80d8

The offset must therefore be a multiple of the element size to be valid in these instructions. However, an unaligned base address is valid in MSA.

This will cause parser to report errors when parsing integer based register assignments, for example: .set r3, will be reported as error.
