* linux, dump_syms: Make style consistent in module unittestChristopher Grant2019-10-291-63/+63
| | | | | | | | | | | | | | | Make the following consistent within the file: - 0x...ULL for unsigned literals. - On pointers, put the asterisk with the type. Context: Made a previous change and saw a mix of styles. Make it consistent for the sake of visual consistency.

* linux, dump_syms: Filter module entries outside specified rangesChristopher Grant2019-10-291-0/+50
| | | | | | | | | | | | | | | | | | | | Partitioned libraries generated with lld and llvm-objcopy currently contain a superset of debug information, beyond what applies to the library itself. This is because objcopy cannot split up debug information by partition - instead, it places a copy of all debug information into each partition. In lieu of potential future support for lld or objcopy becoming able to split up debug information, let dump_syms do the next best thing: - Find the address ranges of all PT_LOAD segments in the lib. - Supply these to the Module being generated. - Filter additions to the Module based on these ranges.

* Add support for parsing the DW_AT_ranges attributesGabriele Svelto2018-08-131-13/+22
| | | | | | | | | | | | | | | | This enables the DWARF reader to properly parse DW_AT_ranges attributes in compilation units and functions. Code covered by a function is now represented by a vector of ranges instead of a single contiguous range and DW_AT_ranges entries are used to populate it. All the code and tests that assumed functions to be contiguous entities has been updated to reflect the change. DW_AT_ranges attributes found in compilation units are parsed but no data is generated for them as it is not currently needed.

* Dump INFO CODE_ID containing Build ID in Linux dump_symsTed Mielczarek2016-06-101-0/+11
| | | | | | | | | | | | | I'd like to have the Build ID available for our symbol server uploading, and this will make it easy. Most of this change is me rewriting dump_symbols_unittest to be typed tests so I could add a new test there. R=mark@chromium.org BUG= Review URL: https://codereview.chromium.org/2052263002 .

| | | | | | | | | | | This patch adds synth_elf::{StringTable,SymbolTable,ELF} classes to produce in-memory ELF files to properly test the Linux symbol dumping code. It also uses those classes to add some basic tests for the WriteSymbolFile function.

| | | | | | | | | | | | This patch avoids unnecessary use of the <cfoo> headers in files that don't actually use the identifiers they declare in the std:: namespace.

* Breakpad symbol dumper: Promise that Module::SetLoadAddress can be called at ↵jimblandy2010-05-051-2/+4
| | | | | | | | | | | | | | | | | | any time. It's possible to imagine an implementation of google_breakpad::Module in which calling SetLoadAddress at different times as the Module is populated would produce different output. For the Mac dumper, we'd like to depend on its current behavior --- that the load address is subtracted off only when writing the symbol file, and can be set at any time prior to that. This patch makes that promise part of Module's contract, and adjusts the test suite to verify that that promise is met. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@588 4c0a9323-5329-0410-9bdc-e9ce6186880e
