call to the MachineCodeEmitter interface and made copying the start line of a function not conditional on whether we're emitting Dwarf debug information. I'll propagate the processDebugLoc() calls to the non-X86 targets in a followup patch. In the long run, it'll probably be better to gather this information through the DwarfWriter, but the DwarfWriter currently depends on the AsmPrinter and TargetAsmInfo, and fixing that would be out of the way for this patch. There's a bug in OProfile 0.9.4 that makes it ignore line numbers for addresses above 4G, and a patch fixing it at http://thread.gmane.org/gmane.linux.oprofile/7634 Sample output: $ sudo opcontrol --reset; sudo opcontrol --start-daemon; sudo opcontrol --start; `pwd`/Debug/bin/lli fib.bc; sudo opcontrol --stop Signalling daemon... done Profiler running. fib(40) == 165580141 Stopping profiling. $ opreport -g -d -l `pwd`/Debug/bin/lli|head -60 Overflow stats not available CPU: Core 2, speed 1998 MHz (estimated) Counted CPU_CLK_UNHALTED events (Clock cycles when not halted) with a unit mask of 0x00 (Unhalted core cycles) count 100000 vma samples % linenr info image name symbol name 00007f67a30370b0 25489 61.2554 fib.c:24 10946.jo fib_left 00007f67a30370b0 1634 6.4106 fib.c:24 00007f67a30370b1 83 0.3256 fib.c:24 00007f67a30370b9 1997 7.8348 fib.c:24 00007f67a30370c6 2080 8.1604 fib.c:27 00007f67a30370c8 988 3.8762 fib.c:27 00007f67a30370cd 1315 5.1591 fib.c:27 00007f67a30370cf 251 0.9847 fib.c:27 00007f67a30370d3 1191 4.6726 fib.c:27 00007f67a30370d6 975 3.8252 fib.c:27 00007f67a30370db 1010 3.9625 fib.c:27 00007f67a30370dd 242 0.9494 fib.c:27 00007f67a30370e1 2782 10.9145 fib.c:28 00007f67a30370e5 3768 14.7828 fib.c:28 00007f67a30370eb 615 2.4128 (no location information) 00007f67a30370f3 6558 25.7287 (no location information) 00007f67a3037100 15603 37.4973 fib.c:29 10946.jo fib_right 00007f67a3037100 1646 10.5493 fib.c:29 00007f67a3037101 45 0.2884 fib.c:29 00007f67a3037109 2372 15.2022 fib.c:29 00007f67a3037116 2234 14.3178 fib.c:32 00007f67a3037118 612 3.9223 fib.c:32 00007f67a303711d 622 3.9864 fib.c:32 00007f67a303711f 385 2.4675 fib.c:32 00007f67a3037123 404 2.5892 fib.c:32 00007f67a3037126 634 4.0633 fib.c:32 00007f67a303712b 870 5.5759 fib.c:32 00007f67a303712d 62 0.3974 fib.c:32 00007f67a3037131 1848 11.8439 fib.c:33 00007f67a3037135 2840 18.2016 fib.c:33 00007f67a303713a 1 0.0064 fib.c:33 00007f67a303713b 1023 6.5564 (no location information) 00007f67a3037143 5 0.0320 (no location information) 000000000080c1e4 15 0.0360 MachineOperand.h:150 lli llvm::MachineOperand::isReg() const 000000000080c1e4 6 40.0000 MachineOperand.h:150 000000000080c1ec 2 13.3333 MachineOperand.h:150 ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76102 91177308-0d34-0410-b5e6-96231b3b80d8
