Subject: [PowerPC] Use real pointers instead of undef
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=88f77a47e96ce3593ae97cf697444d0b14f27426;p=llvm

[PowerPC] Use real pointers instead of undef

The reduced test removed the pointer arguments, but to better survive D58017 and D58070 we need them back.
