[PATCH] D138887: [SPARC] Mark the %g0 register as constant & use it to materialize zeros

[Jessica Clarke via Phabricator via llvm-commits]

jrtc27 added inline comments.


================
Comment at: llvm/test/CodeGen/SPARC/bigreturn.ll:139
 ; SPARC-NEXT:    mov %g0, %i4
+; SPARC-NEXT:    mov %g1, %i5
 ; SPARC-NEXT:    ldd [%i2], %i0
----------------
This is a bit nonsense, it copies the %g0+%g1 register pair into %i4+%i5 then copies %g0 into %i5... it works but it's a regression and points at something very suspect going on
