Though this instruction is not legal for machines with SSSE3 and lower. The fix: In EltsFromConsecutiveLoads, if we have passed legalize stage, we check whether nodes it emits are legal. P.S.: If you get failure in time from 12:00 and till 22:00 (UTC-8), perhaps I'll slow with response, so you better reject this commit.

There're other cases where helper calls will be inserted not limited to epilog. These helper calls do not follow the standard calling convention and won't clobber any YMM registers. (So far, all call conventions will clobber any or part of YMM registers.) This patch enhances the previous fix to cover more cases 'vzerosupper' should not be inserted by checking if that function call won't clobber any YMM registers and skipping it if so. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@196652 91177308-0d34-0410-b5e6-96231b3b80d8

* Error if we see an alias to a declaration.Rafael Espindola2013-11-145-5/+18
| | | | | | | | | | | | | | | In ELF and COFF an alias is just another offset in a section. There is no way to represent an alias to something in another file. In MachO, the spec has the N_INDR type which should allow for exactly that, but is not currently implemented. Given that it is specified but not implemented, we error in codegen to avoid miscompiling but don't reject aliases to declarations in the verifier to leave the option open of implementing it. In the past we have used alias to declarations as a way of implementing weakref, which is why it exists in some old tests which this patch updates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194705 91177308-0d34-0410-b5e6-96231b3b80d8
* AVX-512: Handled extractelement from mask vector;Elena Demikhovsky2013-11-142-0/+33
| | | | | | | Added VMOSHDUP/VMOVSLDUP shuffle instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194691 91177308-0d34-0410-b5e6-96231b3b80d8
* Minor extension to llvm.experimental.patchpoint: don't require a call.Andrew Trick2013-11-141-0/+16
| | | | | | | | If a null call target is provided, don't emit a dummy call. This allows the runtime to reserve as little nop space as it needs without the requirement of emitting a call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194676 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't mangle \n and "Rafael Espindola2013-11-141-0/+6
| | | | | | | | | | There is nothing special about quotes and newlines from the object file point of view, only the assembler has to worry about expanding the \n and \". This patch then removes the special handling from the Mangler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194667 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove AllowQuotesInName and friends from MCAsmInfo.Rafael Espindola2013-11-132-14/+14
| | | | | | | | | | | Accepting quotes is a property of an assembler, not of an object file. For example, ELF can support any names for sections and symbols, but the gnu assembler only accepts quotes in some contexts and llvm-mc in a few more. LLVM should not produce different symbols based on a guess about which assembler will be reading the code it is printing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194575 91177308-0d34-0410-b5e6-96231b3b80d8
