| | | | | | | | | | | | | | { short, short } to short where the second short maps onto the second field of the first struct. In this case, the struct index is not aligned, so we should avoid calling getLink(2), which asserts out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20626 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | numbering values in live ranges for physical registers. The alpha backend currently generates code that looks like this: vreg = preg ... preg = vreg use preg ... preg = vreg use preg etc. Because vreg contains the value of preg coming in, each of the copies back into preg contain that initial value as well. In the case of the Alpha, this allows this testcase: void "foo"(int %blah) { store int 5, int *%MyVar store int 12, int* %MyVar2 ret void } to compile to: foo: ldgp $29, 0($27) ldiq $0,5 stl $0,MyVar ldiq $0,12 stl $0,MyVar2 ret $31,($26),1 instead of: foo: ldgp $29, 0($27) bis $29,$29,$0 ldiq $1,5 bis $0,$0,$29 stl $1,MyVar ldiq $1,12 bis $0,$0,$29 stl $1,MyVar2 ret $31,($26),1 This does not seem to have any noticable effect on X86 code. This fixes PR535. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20536 91177308-0d34-0410-b5e6-96231b3b80d8
