[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

[X86] Handle COPYs of physregs better (regalloc hints) Enable enableMultipleCopyHints() on X86. Original Patch by @jonpa: While enabling the mischeduler for SystemZ, it was discovered that for some reason a test needed one extra seemingly needless COPY (test/CodeGen/SystemZ/call-03.ll). The handling for that is resulted in this patch, which improves the register coalescing by providing not just one copy hint, but a sorted list of copy hints. On SystemZ, this gives ~12500 less register moves on SPEC, as well as marginally less spilling. Instead of improving just the SystemZ backend, the improvement has been implemented in common-code (calculateSpillWeightAndHint(). This gives a lot of test failures, but since this should be a general improvement I hope that the involved targets will help and review the test updates.

[X86] Handle COPYs of physregs better (regalloc hints) Enable enableMultipleCopyHints() on X86. Original Patch by @jonpa: While enabling the mischeduler for SystemZ, it was discovered that for some reason a test needed one extra seemingly needless COPY (test/CodeGen/SystemZ/call-03.ll). The handling for that is resulted in this patch, which improves the register coalescing by providing not just one copy hint, but a sorted list of copy hints. On SystemZ, this gives ~12500 less register moves on SPEC, as well as marginally less spilling. Instead of improving just the SystemZ backend, the improvement has been implemented in common-code (calculateSpillWeightAndHint(). This gives a lot of test failures, but since this should be a general improvement I hope that the involved targets will help and review the test updates.

Bias physical register immediate assignments The machine scheduler currently biases register copies to/from physical registers to be closer to their point of use / def to minimize their live ranges. This change extends this to also physical register assignments from immediate values. This causes a reduction in reduction in overall register pressure and minor reduction in spills and indirectly fixes an out-of-registers assertion (PR39391). Most test changes are from minor instruction reorderings and register name selection changes and direct consequences of that.

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
