[SystemZ] Add test missing from r186148 Sigh, twice in two days sorry. One day I'll remember... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186150 91177308-0d34-0410-b5e6-96231b3b80d8

; Test explicit register names.
;
Use the integrated assembler as default on SystemZ This was already done in clang, this commit now uses the integrated assembler as default when using LLVM tools directly. A number of test cases deliberately using an invalid instruction in inline asm now have to use -no-integrated-as. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225820 91177308-0d34-0410-b5e6-96231b3b80d8

Fix overly pessimistic shortcut in post-RA MachineLICM Post-RA LICM keeps three sets of registers: PhysRegDefs, PhysRegClobbers and TermRegs. When it sees a definition of R it adds all aliases of R to the corresponding set, so that when it needs to test for membership it only needs to test a single register, rather than worrying about aliases there too. E.g. the final candidate loop just has: unsigned Def = Candidates[i].Def; if (!PhysRegClobbers.test(Def) && ...) { to test whether register Def is multiply defined. However, there was also a shortcut in ProcessMI to make sure we didn't add candidates if we already knew that they would fail the final test. This shortcut was more pessimistic than the final one because it checked whether _any alias_ of the defined register was multiply defined. This is too conservative for targets that define register pairs. E.g. on z, R0 and R1 are sometimes used as a pair, so there is a 128-bit register that aliases both R0 and R1. If a loop used R0 and R1 independently, and the definition of R0 came first, we would be able to hoist the R0 assignment (because that used the final test quoted above) but not the R1 assignment (because that meant we had two definitions of the paired R0/R1 register and would fail the shortcut in ProcessMI). This patch just uses the same check for the ProcessMI shortcut as we use in the final candidate loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188774 91177308-0d34-0410-b5e6-96231b3b80d8
