Cast Dwarf_Addr to uintmax_t for printf-formats.\n\nChanges in v2:\n - Cast Dwarf_Addr to unsigned long long for printf-formats.\n\nSigned-off-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nCc: systemtap \u003csystemtap@sources.redhat.com\u003e\nCc: DLE \u003cdle-develop@lists.sourceforge.net\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: K.Prasad \u003cprasad@linux.vnet.ibm.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nLKML-Reference: \u003c20100225133611.6725.45078.stgit@localhost6.localdomain6\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "5c8d1cbbbed39dcab2ecf429d6e56ea548c0fda4", "tree": "8ce3346a689e6f4744b2a48e1178f40560137ca6", "parents": [ "161a26b0c231b5d2e60e9c132fa360cd9dac4720" ], "author": { "name": "Masami Hiramatsu", "email": "mhiramat@redhat.com", "time": "Thu Feb 25 08:36:04 2010 -0500" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 25 17:49:30 2010 +0100" }, "message": "perf probe: Show more lines after last line\n\nShow 2 more lines after the last probe-able line.\nThis will clearly show the last closed-brace of\ninline functions.\n\nSigned-off-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nCc: systemtap \u003csystemtap@sources.redhat.com\u003e\nCc: DLE \u003cdle-develop@lists.sourceforge.net\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: K.Prasad \u003cprasad@linux.vnet.ibm.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nLKML-Reference: \u003c20100225133604.6725.76820.stgit@localhost6.localdomain6\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "161a26b0c231b5d2e60e9c132fa360cd9dac4720", "tree": "65890fa84d614d04ded92b4214f0e76a46b90461", "parents": [ "e92b85e1ffaa0bd8e5d92e7c378a3909e7f23122" ], "author": { "name": "Masami Hiramatsu", "email": "mhiramat@redhat.com", "time": "Thu Feb 25 08:35:57 2010 -0500" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 25 17:49:29 2010 +0100" }, "message": "perf probe: Check function address range strictly in line finder\n\nCheck (inlined) function address range strictly for\nimproving output of probe-able lines of inline functions.\n\nWithout this change, perf probe --line \u003cfunction\u003e sometimes\nshowed other inline function bodies too, because it didn\u0027t\nfilter out inlined functions.\n\nSigned-off-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nCc: systemtap \u003csystemtap@sources.redhat.com\u003e\nCc: DLE \u003cdle-develop@lists.sourceforge.net\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: K.Prasad \u003cprasad@linux.vnet.ibm.com\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nLKML-Reference: \u003c20100225133557.6725.20697.stgit@localhost6.localdomain6\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "e92b85e1ffaa0bd8e5d92e7c378a3909e7f23122", "tree": "6bd934ca363a3529ad4ecb1112c1d2c70c13089b", "parents": [ "804b36068eccd8163ccea420c662fb5d1a21b141" ], "author": { "name": "Masami Hiramatsu", "email": "mhiramat@redhat.com", "time": "Thu Feb 25 08:35:50 2010 -0500" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 25 17:49:29 2010 +0100" }, "message": "perf probe: Use libdw callback routines\n\nUse libdw callback functions aggressively, and remove\nlocal tree-search API.

In such case there were no\nconversion needed, but in\n\n src-\u003eeip \u003d strtoull(src-\u003eline, NULL, 16);\n src-\u003eeip \u003d map-\u003eunmap_ip(map, src-\u003eeip); // \u003d eip + map-\u003estart - map-\u003epgoff\n\nwe were reading absolute address from objdump (e.g. 8048604) and\nthen almost doubling it, because eip \u0026 map-\u003estart are\napproximately close for small programs.\n\nNeedless to say, that later, in record_precise_ip() there was no\nmatching with real runtime IPs.\n\nAnd second, like with `perf annotate` the problem with\nnon-prelinked *.so was that we were doing rip -\u003e objdump address\nconversion wrong.\n\nAlso, because unlike `perf annotate`, `perf top` code does\nannotation based on absolute IPs for performance reasons(*), new\nhelper for mapping objdump addresse to IP is introduced.\n\n(*) we get samples info in absolute IPs, and since we do lots of\n hit-testing on absolute IPs at runtime in record_precise_ip(), it\u0027s\n better to convert objdump addresses to IPs once and do no conversion\n at runtime.\n\nI also had to fix how objdump output is parsed (with hardcoded\n8/16 characters format, which was inappropriate for ET_DYN dsos\nwith small addresses like \u00274ac\u0027)\n\nAlso note, that not all objdump output lines has associtated\nIPs, e.g. look at source lines here:\n\n 000004ac \u003cmy_strlen\u003e:\n extern \"C\"\n int my_strlen(const char *s)\n 4ac: 55 push %ebp\n 4ad: 89 e5 mov %esp,%ebp\n 4af: 83 ec 10 sub $0x10,%esp\n {\n int len \u003d 0;\n 4b2: c7 45 fc 00 00 00 00 movl $0x0,-0x4(%ebp)\n 4b9: eb 08 jmp 4c3 \u003cmy_strlen+0x17\u003e\n\n while (*s) {\n ++len;\n 4bb: 83 45 fc 01 addl $0x1,-0x4(%ebp)\n ++s;\n 4bf: 83 45 08 01 addl $0x1,0x8(%ebp)\n\nSo we mark them with eip\u003d0, and ignore such lines in annotate\nlookup code.\n\nSigned-off-by: Kirill Smelkov \u003ckirr@landau.phys.spbu.ru\u003e\n[ Note: one hunk of this patch was applied by Mike in 57d8188 ]\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nLKML-Reference: \u003c1265550376-12665-1-git-send-email-acme@infradead.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "2161db969313cb94ffd9377a525fb75c3fee9eeb", "tree": "2e658bea3d7d2a082dd50e7984cf8c2bc95fbc9a", "parents": [ "f887f3019e56389a73617f4e70f512e82cc89adb" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 04 10:22:01 2010 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 04 10:22:01 2010 +0100" }, "message": "perf tools: Fix session init on non-modular kernels\n\nperf top and perf record refuses to initialize on non-modular kernels:\nrefuse to initialize:\n\n $ perf top -v\n map_groups__set_modules_path_dir: cannot open /lib/modules/2.6.33-rc6-tip-00586-g398dde3-dirty/\n\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frédéric Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nLKML-Reference: \u003c1265223128-11786-1-git-send-email-acme@infradead.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "f887f3019e56389a73617f4e70f512e82cc89adb", "tree": "176b13e6d9713715d1b4eef75e702b47e6923606", "parents": [ "447a194b393f32699607fd99617a40abd6a95114" ], "author": { "name": "Xiao Guangrong", "email": "xiaoguangrong@cn.fujitsu.com", "time": "Thu Feb 04 16:46:42 2010 +0800" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Feb 04 10:03:03 2010 +0100" }, "message": "perf tools: Clean up O_LARGEFILE et al usage\n\nSetting _FILE_OFFSET_BITS and using O_LARGEFILE, lseek64, etc,\nis redundant.
