From 0e164884423e9f0f22670015a428946ebf178545 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Thu, 4 Apr 2013 03:08:00 +0000 Subject: Add SPARC v9 support for select on 64-bit compares. This requires v9 cmov instructions using the %xcc flags instead of the %icc flags. Still missing: - Select floats on %xcc flags. - Select i64 on %fcc flags. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178737 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/SPARC/64cond.ll | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) (limited to 'test') diff --git a/test/CodeGen/SPARC/64cond.ll b/test/CodeGen/SPARC/64cond.ll index 694909f9e7..6e66a262a4 100644 --- a/test/CodeGen/SPARC/64cond.ll +++ b/test/CodeGen/SPARC/64cond.ll @@ -32,3 +32,25 @@ if.then: if.end: ret void } + +; CHECK: selecti32_xcc +; CHECK: subcc %i0, %i1 +; CHECK: movg %xcc, %i2, %i3 +; CHECK: or %g0, %i3, %i0 +define i32 @selecti32_xcc(i64 %x, i64 %y, i32 %a, i32 %b) { +entry: + %tobool = icmp sgt i64 %x, %y + %rv = select i1 %tobool, i32 %a, i32 %b + ret i32 %rv +} + +; CHECK: selecti64_xcc +; CHECK: subcc %i0, %i1 +; CHECK: movg %xcc, %i2, %i3 +; CHECK: or %g0, %i3, %i0 +define i64 @selecti64_xcc(i64 %x, i64 %y, i64 %a, i64 %b) { +entry: + %tobool = icmp sgt i64 %x, %y + %rv = select i1 %tobool, i64 %a, i64 %b + ret i64 %rv +} -- cgit v1.2.3
