* [CommandLine] Don't print empty sentinel values from EnumValN lists in help textJames Henderson2019-02-041-1/+1

Prior to this change, this empty-named value appears in the command-line help text: -some-option - some help text =v1 - description 1 =v2 - description 2 = - This change improves the help text for these sort of options in a number of ways: 1) ValueOptional options with an empty-named value now print their help text twice: both without and then with '=<value>' after the name. The latter version then lists the allowed values after it. 2) Empty-named values with no help text in ValueOptional options are not listed in the permitted values. -some-option - some help text -some-option=<value> - some help text =v1 - description 1 =v2 - description 2 3) Otherwise empty-named options are printed as =<empty> rather than simply '='. 4) Option values without help text do not have the '-' separator printed. -some-option=<value> - some help text =v1 - description 1 =v2 =<empty> - description It also tweaks the llvm-symbolizer -functions help text to not print a trailing ':' as that looks bad combined with 1) above.

* [llvm-symbolizer] Add switch to adjust addresses by fixed offsetJames Henderson2019-01-251-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | If a stack trace or similar has a list of addresses from an executable or DSO loaded at a variable address (e.g. due to ASLR), the addresses will not directly correspond to the addresses stored in the object file. If a user wishes to use llvm-symbolizer, they have to subtract the load address from every address. This is somewhat inconvenient, especially as the output of --print-address will result in the adjusted address being listed, rather than the address coming from the stack trace, making it harder to map results between the two. This change adds a new switch to llvm-symbolizer --adjust-vma which takes an offset, which is then used to automatically do this calculation. The printed address remains the input address (allowing for easy mapping), whilst the specified offset is applied to the addresses when performing the lookup. The switch is conceptually similar to llvm-objdump's new switch of the same name (see D57051), which in turn mirrors a GNU switch. There is no equivalent switch in addr2line.

* [llvm-symbolizer] Add support for -i and -inlines as aliases for -inliningDouglas Yung2019-01-241-0/+7
| | | | | | | | | | | | | | This change adds two options, -i and -inlines as aliases for the -inlining option to llvm-symbolizer to improve compatibility with the GNU addr2line utility which accepts these options. It also modifies existing tests that use -inlining to exercise these new aliases as well. This fixes PR40073.

* [llvm-symbolizer] Improve compatibility of --functions with GNU addr2lineJames Henderson2019-01-231-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | This fixes https://bugs.llvm.org/show_bug.cgi?id=40072. GNU addr2line's --functions switch is off by default, has a short alias of -f, and does not take an argument. This patch changes llvm-symbolizer to allow the second and third point (changing the default behaviour may have negative impacts on users). If the option is missing a value, it now treats it as "linkage". This change does cause one previously valid command-line to behave differently. Before --functions <value> was accepted, but now only --functions=<value> is allowed (as well as --functions). The old behaviour will result in the value being treated as a positional argument. The previous testing for --functions=short has been pulled out into a new test that also tests the other accepted values and option formats.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

* DebugInfo: Provide option for explicitly specifying the name of the DWP fileDavid Blaikie2017-07-301-2/+8
| | | | | | | | | | | | | | | | If you've archived the DWP file somewhere it's probably useful to be able to just tell llvm-symbolizer where it is when you're symbolizing stack traces from the binary. This only provides a mechanism for specifying a single DWP file, good if you're symbolizing a program with a single DWP file, but it's likely if the program is dynamically linked that you might have a DWP for each dynamic library - in which case this feature won't help (at least as it's surfaced in llvm-symbolizer for now) - in theory it could be extended to specify a collection of DWP files that could all be consulted for split CU hash resolution. llvm-svn: 309498

| | | | | | | | | | | | | | | | | | | | | Summary: Previously we would try to load PDBs for every PE executable we tried to symbolize. If that failed, we would fall back to DWARF. If there wasn't any DWARF, we'd print mostly useless symbol information using the export table. With this change, we only try to load PDBs for executables that claim to have them. If that fails, we can now print an error rather than falling back silently. This should make it a lot easier to diagnose and fix common symbolization issues, such as not having DIA or not having a PDB.
