From f7f48060a60cc7d4237785975039ca5e8e59d179 Mon Sep 17 00:00:00 2001 From: Mark Wielaard Date: Sat, 2 Jun 2018 00:09:02 +0200 Subject: [PATCH] 0.171-1 - New upstream release. - DWARF5 and split dwarf, including GNU DebugFission, support. - readelf: Handle all new DWARF5 sections. --debug-dump=info+ will show split unit DIEs when found. --dwarf-skeleton can be used when inspecting a .dwo file. Recognizes GNU locviews with --debug-dump=loc. - libdw: New functions dwarf_die_addr_die, dwarf_get_units, dwarf_getabbrevattr_data and dwarf_cu_info. libdw will now try to resolve the alt file on first use when not set yet with dwarf_set_alt. dwarf_aggregate_size() now works with multi-dimensional arrays. - libdwfl: Use process_vm_readv when available instead of ptrace. - backends: Add a RISC-V backend. --- .gitignore | 1 + elfutils-0.170-GNU_variable_value.patch | 46 - elfutils-0.170-core-pid.patch | 120 -- elfutils-0.170-dwarf_aggregate_size.patch | 170 --- elfutils-0.170-elf_sync.patch | 306 ----- elfutils-0.170-locviews.patch | 1270 ------------------ elfutils-0.170-m68k-packed-not-aligned.patch | 67 - elfutils-0.170-new-notes-hack.patch | 25 - elfutils-0.170-sys-ptrace.patch | 113 -- elfutils-0.170-unwind.patch | 128 -- elfutils-0.171-new-notes-hack.patch | 30 + elfutils.spec | 43 +- sources | 2 +- testfile-sizes3.o.bz2 | Bin 1208 -> 0 bytes 14 files changed, 53 insertions(+), 2268 deletions(-) delete mode 100644 elfutils-0.170-GNU_variable_value.patch delete mode 100644 elfutils-0.170-core-pid.patch delete mode 100644 elfutils-0.170-dwarf_aggregate_size.patch delete mode 100644 elfutils-0.170-elf_sync.patch delete mode 100644 elfutils-0.170-locviews.patch delete mode 100644 elfutils-0.170-m68k-packed-not-aligned.patch delete mode 100644 elfutils-0.170-new-notes-hack.patch delete mode 100644 elfutils-0.170-sys-ptrace.patch delete mode 100644 elfutils-0.170-unwind.patch create mode 100644 elfutils-0.171-new-notes-hack.patch delete mode 100644 testfile-sizes3.o.bz2 diff --git a/.gitignore b/.gitignore index a5b5128..55cd66b 100644 --- a/.gitignore +++ b/.gitignore @@ -11,3 +11,4 @@ /elfutils-0.168.tar.bz2 /elfutils-0.169.tar.bz2 /elfutils-0.170.tar.bz2 +/elfutils-0.171.tar.bz2 diff --git a/elfutils-0.170-GNU_variable_value.patch b/elfutils-0.170-GNU_variable_value.patch deleted file mode 100644 index 8ff5f5c..0000000 --- a/elfutils-0.170-GNU_variable_value.patch +++ /dev/null @@ -1,46 +0,0 @@ -commit e23c71330c3b332d19fdf9e48ca8b03680d9ad34 -Author: Mark Wielaard -Date: Thu Nov 2 16:23:24 2017 +0100 - - readelf: Handle DW_OP_GNU_variable_value. - - Also format both DW_OP_call_ref and DW_OP_GNU_variable_value argument - as a normal DIE reference. - - Signed-off-by: Mark Wielaard - -diff --git a/libdw/dwarf.h b/libdw/dwarf.h -index 902d261..8edf719 100644 ---- a/libdw/dwarf.h -+++ b/libdw/dwarf.h -@@ -545,6 +545,7 @@ enum - DW_OP_GNU_convert = 0xf7, - DW_OP_GNU_reinterpret = 0xf9, - DW_OP_GNU_parameter_ref = 0xfa, -+ DW_OP_GNU_variable_value = 0xfd, - - DW_OP_lo_user = 0xe0, /* Implementation-defined range start. */ - DW_OP_hi_user = 0xff /* Implementation-defined range end. */ -diff --git a/src/readelf.c b/src/readelf.c -index 5e2f3fc..833884b 100644 ---- a/src/readelf.c -+++ b/src/readelf.c -@@ -4160,6 +4160,7 @@ print_ops (Dwfl_Module *dwflmod, Dwarf *dbg, int indent, int indentrest, - break; - - case DW_OP_call_ref: -+ case DW_OP_GNU_variable_value: - /* Offset operand. */ - if (ref_size != 4 && ref_size != 8) - goto invalid; /* Cannot be used in CFA. */ -@@ -4170,8 +4171,8 @@ print_ops (Dwfl_Module *dwflmod, Dwarf *dbg, int indent, int indentrest, - addr = read_8ubyte_unaligned (dbg, data); - data += ref_size; - CONSUME (ref_size); -- -- printf ("%*s[%4" PRIuMAX "] %s %#" PRIxMAX "\n", -+ /* addr is a DIE offset, so format it as one. */ -+ printf ("%*s[%4" PRIuMAX "] %s [%6" PRIxMAX "]\n", - indent, "", (uintmax_t) offset, - op_name, (uintmax_t) addr); - offset += 1 + ref_size; diff --git a/elfutils-0.170-core-pid.patch b/elfutils-0.170-core-pid.patch deleted file mode 100644 index 6354f21..0000000 --- a/elfutils-0.170-core-pid.patch +++ /dev/null @@ -1,120 +0,0 @@ -commit 699a741b488010d56cc358a5f7b4d8a8f4886347 -Author: Mark Wielaard -Date: Sat Dec 23 23:16:24 2017 +0100 - - tests: Try to use coredumpctl to extract core files. - - If systemd-coredump is installed we have to use coredumpctl to extract - the core file to test.
