[X86] Regenerated integer divide tests to test on 32 and 64 bit targets llvm-svn: 287104
2016-11-16 22:12:11 +08:00
; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py
; RUN: llc < %s -mtriple=i686-unknown | FileCheck %s --check-prefix=X32
; RUN: llc < %s -mtriple=x86_64-unknown | FileCheck %s --check-prefix=X64
When both x/y and x%y are needed (x and y both scalar integer), compute both results with a single div or idiv instruction. This uses new X86ISD nodes for DIV and IDIV which are introduced during the legalize phase so that the SelectionDAG's CSE can automatically eliminate redundant computations. llvm-svn: 42308
