* [Dominators] Don't compute DFS InOut numbers eagerly.Jakub Kuderski2017-06-303-3/+3
| | | | | | | | | | | | | | | | | Summary: DFS InOut numbers currently get eagerly computer upon DomTree construction. They are only needed to answer dome dominance queries and they get invalidated by updates and recalculations. Because of that, it is faster in practice to compute them lazily when they are actually needed. Clang built without this patch takes 6m 45s to boostrap on my machine, and with the patch applied 6m 38s.

| | | | | | | | | | | | | Under Windows Itanium, we need to export virtual and non-virtual thunks if the functions being thunked are exported. These thunks would previously inherit their dllexport attribute from the declaration, but r298330 changed declarations to not have dllexport attributes. We therefore need to add the dllexport attribute to the definition ourselves now. Differential Revision: https://reviews.llvm.org/D34850 llvm-svn: 306770

* [clang-format] Switch to case-insensitive header matching and use it toChandler Carruth2017-06-293-6/+31
| | | | | | | | | | | | | | | | | | | | | | | improve support for LLVM-style include sorting. This really is a collection of improvements to the rules for LLVM include sorting: - We have gmock headers now, so it adds support for those to one of the categories. - LLVM does use 'FooTest.cpp' files to test 'Foo.h' so it adds that suffix for finding a main header. - At times the test file's case may not match the header file's case, so switch to case-insensitive regex matching of header names. With this set of changes, I can't spot any misbehaviors when re-sorting all of LLVM's unittest '#include' lines. Thanks to Eric and Daniel for help testing and refining the patch during review!

* Remove redundant copy in recurrencesTaewook Oh2017-06-294-6/+410
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: If there is a chain of instructions formulating a recurrence, commuting operands can help removing a redundant copy. In the following example code, ``` BB#1: ; Loop Header %vreg0<def> = COPY %vreg13<kill>; GR32:%vreg0,%vreg13 ... BB#6: ; Loop Latch %vreg2<def> = COPY %vreg15<kill>; GR32:%vreg2,%vreg15 %vreg10<def,tied1> = ADD32rr %vreg1<kill,tied0>, %vreg0<kill>, %EFLAGS<imp-def,dead>; GR32:%vreg10,%vreg1,%vreg0 %vreg3<def,tied1> = ADD32rr %vreg2<kill,tied0>, %vreg10<kill>, %EFLAGS<imp-def,dead>; GR32:%vreg3,%vreg2,%vreg10 CMP32ri8 %vreg3, 10, %EFLAGS<imp-def>; GR32:%vreg3 %vreg13<def> = COPY %vreg3<kill>; GR32:%vreg13,%vreg3 JL_1 <BB#1>, %EFLAGS<imp-use,kill> ``` Existing two-address generation pass generates following code: ``` BB#1: %vreg0<def> = COPY %vreg13<kill>; GR32:%vreg0,%vreg13 ... BB#6: Predecessors according to CFG: BB#5 BB#4 %vreg2<def> = COPY %vreg15<kill>; GR32:%vreg2,%vreg15 %vreg10<def> = COPY %vreg1<kill>; GR32:%vreg10,%vreg1 %vreg10<def,tied1> = ADD32rr %vreg10<tied0>, %vreg0<kill>, %EFLAGS<imp-def,dead>; GR32:%vreg10,%vreg0 %vreg3<def> = COPY %vreg10<kill>; GR32:%vreg3,%vreg10 %vreg3<def,tied1> = ADD32rr %vreg3<tied0>, %vreg2<kill>, %EFLAGS<imp-def,dead>; GR32:%vreg3,%vreg2 CMP32ri8 %vreg3, 10, %EFLAGS<imp-def>; GR32:%vreg3 %vreg13<def> = COPY %vreg3<kill>; GR32:%vreg13,%vreg3 JL_1 <BB#1>, %EFLAGS<imp-use,kill> JMP_1 <BB#7> ``` This is suboptimal because the assembly code generated has a redundant copy at the end of #BB6 to feed %vreg13 to BB#1: ``` .LBB0_6: addl %esi, %edi addl %ebx, %edi cmpl $10, %edi movl %edi, %esi jl .LBB0_1 ``` This redundant copy can be elimiated by making instructions in the recurrence chain to compute the value "into" the register that actually holds the feedback value. In this example, this can be achieved by commuting %vreg0 and %vreg1 to compute %vreg10. With that change, code after two-address generation becomes ``` BB#1: %vreg0<def> = COPY %vreg13<kill>; GR32:%vreg0,%vreg13 ... BB#6: derived from LLVM BB %bb7 Predecessors according to CFG: BB#5 BB#4 %vreg2<def> = COPY %vreg15<kill>; GR32:%vreg2,%vreg15 %vreg10<def> = COPY %vreg0<kill>; GR32:%vreg10,%vreg0 %vreg10<def,tied1> = ADD32rr %vreg10<tied0>, %vreg1<kill>, %EFLAGS<imp-def,dead>; GR32:%vreg10,%vreg1 %vreg3<def> = COPY %vreg10<kill>; GR32:%vreg3,%vreg10 %vreg3<def,tied1> = ADD32rr %vreg3<tied0>, %vreg2<kill>, %EFLAGS<imp-def,dead>; GR32:%vreg3,%vreg2 CMP32ri8 %vreg3, 10, %EFLAGS<imp-def>; GR32:%vreg3 %vreg13<def> = COPY %vreg3<kill>; GR32:%vreg13,%vreg3 JL_1 <BB#1>, %EFLAGS<imp-use,kill> JMP_1 <BB#7> ``` and the final assembly does not have redundant copy: ``` .LBB0_6: addl %edi, %eax addl %ebx, %eax cmpl $10, %eax jl .LBB0_1 ``` Reviewers: qcolombet, MatzeB, wmi Reviewed By: wmi Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D31821 llvm-svn: 306758

* [AliasSetTracker] Don't drop AA MD so eagerlyKeno Fischer2017-06-293-4/+112
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: When we have patterns like loop: %la = load %ptr, !tbaa %lba = load %ptr, !tbaa !noalias AliasSetTracker would previously think that the two types of annotation for the pointer conflict, dropping both for the purpose of determining alias sets. That is clearly way too conservative, as the tbaa is still valid whether or not one of the memory accesses has additional AA metadata. We could go one step further and attempt to properly merge the AA metadata, but it's not clear that that would be worth it since that may introduce additional MD nodes, which may be undesirable since this is merely an Analysis.
