* addr2line: Add explicit fflush for stdout when reading from stdin.Mark Wielaard2018-05-121-0/+1
| | | | | | | | | To make it possible to use eu-addr2line interactively through a pipe we need to explicitly flush stdout after handling each line from stdin. https://sourceware.org/bugzilla/show_bug.cgi?id=23173 Signed-off-by: Mark Wielaard <[email protected]>
* Use fallthrough attribute.Joshua Watt2018-02-101-1/+1
| | | | | | | | | | | | | | | Use __attribute__ ((fallthrough)) to indicate switch case fall through instead of a comment. This ensures that the fallthrough warning is not triggered even if the file is pre-processed (hence stripping the comments) before it is compiled. The actual fallback implementation is hidden behind a FALLBACK macro in case the compiler doesn't support it. Finally, the -Wimplict-fallthrough warning was upgraded to only allow the attribute to satisfy it; a comment alone is no longer sufficient. Signed-off-by: Joshua Watt <[email protected]>
* Move print_version into printversion.{h|c}Ulf Hermann2017-02-171-0/+1
| | | | | | | | Rename version.c so that the implementation is called after the header and the header doesn't clash with the toplevel version.h. print_version depends on argp and is only used in the tools. Signed-off-by: Ulf Hermann <[email protected]>

| | | | | | | | | | | | | | | | | fedorahosted used to be our home, but we are now hosted at sourceware. Change the elfutils project home to http://elfutils.org/ Point hosted services (email, release, git, bug tracker and web pages) to https://sourceware.org/elfutils/ Move design notes from README to NOTES. Add URLs for home, releases, bugs, git and mailinglist to README. Make the --version output of all tools the same by using a common print_version function and update the publicly shown copyright holder to the elfutils developers.

* Add GCC7 -Wimplicit-fallthrough support/fixes.Mark Wielaard2016-11-101-0/+1
| | | | | | | | | | | GCC7 will have a new -Wimplicit-fallthrough warning. It did catch one small buglet in elflint option procession. So it seems useful to enable to make sure all swatch case fallthroughs are deliberate. Add configure check to detect whether gcc support -Wimplicit-fallthrough and enable it. Add fixes and explicit fallthrough comments where necessary. Signed-off-by: Mark Wielaard <[email protected]>

* addr2line: Set scopes to NULL after free in handle_address.Mark Wielaard2015-05-271-0/+1
| | | | | | | If dwarf_getscopes_die () fails then scopes might not be reset and we could cause a double free. Signed-off-by: Mark Wielaard <[email protected]>
* addr2line: Add --pretty-print option to show all information on one line.Mark Wielaard2015-05-271-11/+36
| | | | | | | | | | | | | | | | | | This adds an option --pretty-print to eu-addr2line to show all information on one line and all inlines on a line of their own. This mimics the same option from binutils addr2line, but without the short option variant -p. Since we already use -p to select the process. Example output: eu-addr2line --pretty-print -s -i -f -C -p$(pidof firefox) 0x00007f368c6f8915 mozilla::ReentrantMonitor::Wait(unsigned int) at ReentrantMonitor.h:92 (inlined by) mozilla::ReentrantMonitorAutoEnter::Wait(unsigned int) at ReentrantMonitor.h:190 A couple of tests were added to check the output matches that of binutils addr2line.

* addr2line: Add demangler support.Mark Wielaard2015-05-271-6/+42
| | | | | | | Makes the -C, --demangle option visible and implements it (ignoring the demangle style argument). Adds a new test with sample output. Signed-off-by: Mark Wielaard <[email protected]>

* addr2line: Always parse addresses as hex numbers.Mark Wielaard2015-05-271-2/+2
| | | | | | | | We would sometimes interpret input addresses as decimal or octal. That could be confusing and isn't what binutils addr2line does. Be consistent and always treat input addresses as hex. Signed-off-by: Mark Wielaard <[email protected]>
* addr2line: Split options in input and output format groups.Mark Wielaard2015-05-271-3/+5
| | | | | | | This makes it clear that -j, --section=NAME is about how input is treated, not how the output is formatted. Signed-off-by: Mark Wielaard <[email protected]>
* Drop mtrace calls.Max Filippov2015-05-041-4/+0

* addr2line: Iterate scopes for inline's parent functionJosh Stone2014-12-111-1/+17
| | | | | | | | The function which contains an inline might not be the immediate next die scope. For instance, there may be a lexical scope in between. Instead, iterate the remaining scopes until an appropriate tag is found. Signed-off-by: Josh Stone <[email protected]>
* addr2line: handle_address initialize scopes to NULL.Mark Wielaard2014-01-241-1/+1
| | | | | | | | | dwarf_getscopes returns the number of scope DIEs containing a PC address. It returns -1 for errors or 0 if no scopes match PC. If dwarf_getscopes returned 0, then scopes will not be allocated and handle_address might free the uninitialized scopes pointer. Make sure it always has a defined value.

* libdwfl: Introduce dwfl_module_getsym_info and dwfl_module_addrinfo.Mark Wielaard2013-12-201-8/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some arches like ppc64 use function descriptor values instead of function addresses causing matching of names and addresses to fail when using dwfl_module_getsym or dwfl_module_addrsym. Add ebl hook to resolve any function descriptor values found in non-ET_REL modules. The new function dwfl_module_getsym_info doesn't adjust the symbol value in any way, but returns the adjusted and/or resolved address associated with the symbol separately. The new function dwfl_module_addrinfo resolves against both the address associated with the symbol (which could be the function entry address) value and the adjusted st_value. So that it is easy to resolve and match either function descriptors and/or function entry addresses. Since these new functions also return more information they replace the dwfl_module_getsym_elf and dwfl_module_addrsym_elf functions that never made it into a released elfutils version. addr2line and readelf now use the new functions when looking up functions names. addr2line will now also display the section the address was found in when given -x. Extra testcases were added for both addr2line and the dwflsyms testscase. Signed-off-by: Mark Wielaard <[email protected]>
* addr2line: Support -i, --inlines output option.Mark Wielaard2013-08-131-20/+120
| | | | | | | | | | | | Show all source locations that caused inline expansion of subroutines at the given address. This can easily be supported by using libdw dwarf_getscopes_die which will give all nested inlined subroutines. When -f, --functions is given also show the function names where the subroutines were inlined. The output matches that of binutils addr2line --inlines.

* addr2line: Remove newline from strings returned by getline.Mark Wielaard2013-08-121-1/+5
| | | | | | | | | | | getline can return strings with a newline as last character when reading from stdin. This could cause confusing symbol lookup failures like: addr2line: cannot find symbol 'foo ' So if the last character of the buf returned by getline is a newline just null-terminate it right there. Also add a new testcase run-addr2line-test.sh. Signed-off-by: Mark Wielaard <[email protected]>
