1;; Test callsite context graph generation for call graph with two memprof 2;; contexts and partial inlining, requiring generation of a new fused node to 3;; represent the inlined sequence while matching callsite nodes onto the graph. 4;; Also tests graph and IR cloning. 5;; 6;; Original code looks like: 7;; 8;; char *bar() { 9;; return new char[10]; 10;; } 11;; 12;; char *baz() { 13;; return bar(); 14;; } 15;; 16;; char *foo() { 17;; return baz(); 18;; } 19;; 20;; int main(int argc, char **argv) { 21;; char *x = foo(); 22;; char *y = foo(); 23;; memset(x, 0, 10); 24;; memset(y, 0, 10); 25;; delete[] x; 26;; sleep(10); 27;; delete[] y; 28;; return 0; 29;; } 30;; 31;; Code compiled with -mllvm -memprof-ave-lifetime-cold-threshold=5 so that the 32;; memory freed after sleep(10) results in cold lifetimes. 33;; 34;; The code below was created by forcing inlining of baz into foo, and 35;; bar into baz. Due to the inlining of bar we will initially have two 36;; allocation nodes in the graph. This tests that we correctly match 37;; foo (with baz inlined) onto the graph nodes first, and generate a new 38;; fused node for it. We should then not match baz (with bar inlined) as that 39;; is not reached by the MIB contexts (since all calls from main will look 40;; like main -> foo(+baz) -> bar after the inlining reflected in this IR). 41;; 42;; The IR was then reduced using llvm-reduce with the expected FileCheck input. 43 44;; -stats requires asserts 45; REQUIRES: asserts 46 47; RUN: opt -thinlto-bc %s >%t.o 48; RUN: llvm-lto2 run %t.o -enable-memprof-context-disambiguation \ 49; RUN: -supports-hot-cold-new \ 50; RUN: -r=%t.o,main,plx \ 51; RUN: -r=%t.o,_ZdaPv, \ 52; RUN: -r=%t.o,sleep, \ 53; RUN: -r=%t.o,_Znam, \ 54; RUN: -memprof-verify-ccg -memprof-verify-nodes -memprof-dump-ccg \ 55; RUN: -memprof-export-to-dot -memprof-dot-file-path-prefix=%t. \ 56; RUN: -stats -pass-remarks=memprof-context-disambiguation -save-temps \ 57; RUN: -o %t.out 2>&1 | FileCheck %s --check-prefix=DUMP \ 58; RUN: --check-prefix=STATS --check-prefix=STATS-BE \ 59; RUN: --check-prefix=STATS-INPROCESS-BE --check-prefix=REMARKS 60 61; RUN: cat %t.ccg.postbuild.dot | FileCheck %s --check-prefix=DOT 62;; We should create clones for foo and bar for the call from main to allocate 63;; cold memory. 64; RUN: cat %t.ccg.cloned.dot | FileCheck %s --check-prefix=DOTCLONED 65 66; RUN: llvm-dis %t.out.1.4.opt.bc -o - | FileCheck %s --check-prefix=IR 67 68 69;; Try again but with distributed ThinLTO 70; RUN: llvm-lto2 run %t.o -enable-memprof-context-disambiguation \ 71; RUN: -supports-hot-cold-new \ 72; RUN: -thinlto-distributed-indexes \ 73; RUN: -r=%t.o,main,plx \ 74; RUN: -r=%t.o,_ZdaPv, \ 75; RUN: -r=%t.o,sleep, \ 76; RUN: -r=%t.o,_Znam, \ 77; RUN: -memprof-verify-ccg -memprof-verify-nodes -memprof-dump-ccg \ 78; RUN: -memprof-export-to-dot -memprof-dot-file-path-prefix=%t2. \ 79; RUN: -stats -pass-remarks=memprof-context-disambiguation \ 80; RUN: -o %t2.out 2>&1 | FileCheck %s --check-prefix=DUMP \ 81; RUN: --check-prefix=STATS 82 83; RUN: cat %t.ccg.postbuild.dot | FileCheck %s --check-prefix=DOT 84;; We should create clones for foo and bar for the call from main to allocate 85;; cold memory. 86; RUN: cat %t.ccg.cloned.dot | FileCheck %s --check-prefix=DOTCLONED 87 88;; Run ThinLTO backend 89; RUN: opt -passes=memprof-context-disambiguation \ 90; RUN: -memprof-import-summary=%t.o.thinlto.bc \ 91; RUN: -stats -pass-remarks=memprof-context-disambiguation \ 92; RUN: %t.o -S 2>&1 | FileCheck %s --check-prefix=IR \ 93; RUN: --check-prefix=STATS-BE --check-prefix=STATS-DISTRIB-BE \ 94; RUN: --check-prefix=REMARKS 95 96source_filename = "inlined.ll" 97target datalayout = "e-m:e-p270:32:32-p271:32:32-p272:64:64-i64:64-f80:128-n8:16:32:64-S128" 98target triple = "x86_64-unknown-linux-gnu" 99 100define internal ptr @_Z3barv() #0 { 101entry: 102 %call = call ptr @_Znam(i64 0), !memprof !0, !callsite !5 103 ret ptr null 104} 105 106declare ptr @_Znam(i64) 107 108define internal ptr @_Z3bazv() #0 { 109entry: 110 %call.i = call ptr @_Znam(i64 0), !memprof !0, !callsite !6 111 ret ptr null 112} 113 114define internal ptr @_Z3foov() #0 { 115entry: 116 %call.i = call ptr @_Z3barv(), !callsite !7 117 ret ptr null 118} 119 120define i32 @main() #0 { 121entry: 122 %call = call ptr @_Z3foov(), !callsite !8 123 %call1 = call ptr @_Z3foov(), !callsite !9 124 ret i32 0 125} 126 127declare void @_ZdaPv() 128 129declare i32 @sleep() 130 131attributes #0 = { noinline optnone } 132 133!0 = !{!1, !3} 134!1 = !{!2, !"notcold"} 135!2 = !{i64 9086428284934609951, i64 -5964873800580613432, i64 2732490490862098848, i64 8632435727821051414} 136!3 = !{!4, !"cold"} 137!4 = !{i64 9086428284934609951, i64 -5964873800580613432, i64 2732490490862098848, i64 -3421689549917153178} 138!5 = !{i64 9086428284934609951} 139!6 = !{i64 9086428284934609951, i64 -5964873800580613432} 140!7 = !{i64 -5964873800580613432, i64 2732490490862098848} 141!8 = !{i64 8632435727821051414} 142!9 = !{i64 -3421689549917153178} 143 144 145; DUMP: CCG before cloning: 146; DUMP: Callsite Context Graph: 147 148; DUMP: Node [[BAZ:0x[a-z0-9]+]] 149; DUMP: Versions: 1 MIB: 150; DUMP: AllocType 1 StackIds: 1, 2 151; DUMP: AllocType 2 StackIds: 1, 3 152; DUMP: (clone 0) 153; DUMP: AllocTypes: NotColdCold 154; DUMP: ContextIds: 1 2 155; DUMP: CalleeEdges: 156; DUMP: CallerEdges: 157; DUMP: Edge from Callee [[BAZ]] to Caller: [[FOO2:0x[a-z0-9]+]] AllocTypes: NotColdCold ContextIds: 1 2 158 159;; This is leftover from the MIB on the alloc inlined into baz.
