Add triple to test/CodeGen/PowerPC/stfiwx-2 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178486 91177308-0d34-0410-b5e6-96231b3b80d8 2013-04-01 18:18:44 +00:00			`; RUN: llc < %s -mtriple=powerpc-unknown-linux-gnu -mcpu=g5 \| FileCheck %s`
Fix a latent bug exposed by my truncstore patch. We compiled stfiwx-2.ll to: _test: fctiwz f0, f1 stfiwx f0, 0, r4 blr instead of: _test: fctiwz f0, f1 stfd f0, -8(r1) nop nop lwz r2, -4(r1) stb r2, 0(r4) blr The former is not correct (stores 4 bytes, not 1). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46161 91177308-0d34-0410-b5e6-96231b3b80d8 2008-01-18 16:54:56 +00:00

Add more PPC floating-point conversion instructions The P7 and A2 have additional floating-point conversion instructions which allow a direct two-instruction sequence (plus load/store) to convert from all combinations (signed/unsigned i32/i64) <--> (float/double) (on previous cores, only some combinations were directly available). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178480 91177308-0d34-0410-b5e6-96231b3b80d8 2013-04-01 17:52:07 +00:00			`; CHECK: fctiwz 0, 1`
