* llvm.experimental.stackmap: fix encoding of large constants.Andrew Trick2014-01-09
| | | | | | | | | | In the stackmap format we advertise the constant field as signed. However, we were determining whether to promote to a 64-bit constant pool based on an unsigned comparison.

* Conservatively handle multiple MMOs in MIsNeedChainEdgeHal Finkel2014-01-08
| | | | | | | | | | | | | | | | | | | | | | MIsNeedChainEdge, which is used by -enable-aa-sched-mi (AA in misched), had an llvm_unreachable when -enable-aa-sched-mi is enabled and we reach an instruction with multiple MMOs. Instead, return a conservative answer. This allows testing -enable-aa-sched-mi on x86. Also, this moves the check above the isUnsafeMemoryObject checks. isUnsafeMemoryObject is currently correct only for instructions with one MMO (as noted in the comment in isUnsafeMemoryObject): // We purposefully do no check for hasOneMemOperand() here // in hope to trigger an assert downstream in order to // finish implementation. The problem with this is that, had the candidate edge passed the "!MIa->mayStore() && !MIb->mayStore()" check, the hoped-for assert would never happen (which could, in theory, lead to incorrect behavior if one of these secondary MMOs was volatile, for example). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198795 91177308-0d34-0410-b5e6-96231b3b80d8

* [x86] Make AsmParser validate registers for memory operands a bit betterDavid Woodhouse2014-01-08
| | | | | | | | | | | | We can't do a perfect job here. We *have* to allow (%dx) even in 64-bit mode, for example, because it might be used for an unofficial form of the in/out instructions. We actually want to do a better job of validation *later*. Perhaps *instead* of doing it where we are at the moment. But for now, doing what validation we *can* do in the place that the code already has its validation, is an improvement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198760 91177308-0d34-0410-b5e6-96231b3b80d8
* [x86] Fix MOV8ao8 et al for 16-bit mode, fix up disassembler to understandDavid Woodhouse2014-01-08
| | | | | | | | | | It seems there is no separate instruction class for having AdSize *and* OpSize bits set, which is required in order to disambiguate between all these instructions. So add that to the disassembler. Hm, perhaps we do need an AdSize16 bit after all? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198759 91177308-0d34-0410-b5e6-96231b3b80d8
* [x86] Use 16-bit addressing where possible in 16-bit modeDavid Woodhouse2014-01-08
| | | | | | | | | Where "where possible" means that it's an immediate value and it's below 0x10000. In fact GAS will either truncate or error with larger values, and will insist on using the addr32 prefix to get 32-bit addressing. So perhaps we should do that, in a later patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198758 91177308-0d34-0410-b5e6-96231b3b80d8

* Add ARM fconsts/fconstd aliases for vmov.f32/vmov.f64David Peixotto2014-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds the pre-UAL aliases of fconsts and fconstd for vmov.f32 and vmov.f64. They use an InstAlias rather than a MnemonicAlias to properly support the predicate operand. We need to support encoded 8-bit constants in order to implement the pre-UAL fconsts/fconstd aliases for vmov.f32/vmov.f64, so this commit also fixes parsing of encoded floating point constants used in vmov.f32/vmov.f64 instructions. Now we can support assembly code like this: fconsts s0, #0x70 which is equivalent to vmov.f32 s0, #1.0. Most of the code was already in place to support this feature. Previously the code was trying to accept encoded 8-bit float constants for the vmov.f32/vmov.f64 instructions. It looks like the support for parsing encoded floats was lost in a refactoring in commit r148556 and we did not have any tests in place to catch it. The change in this commit is to keep the parsed value as a 32-bit float instead of a 64-bit double because that is what the isFPImm() function expects to find. There is no loss of precision by using a 32-bit float here because we are still limited to an 8-bit encoded value in the end. Additionally, we explicitly reject encoded 8-bit floats for vmovf.32/64. This is the same as the current behavior, but we now do it explicitly rather than accidently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198697 91177308-0d34-0410-b5e6-96231b3b80d8
