4 days[llvm-objdump] Add inlined function display support (#142246)gulfemsavrun1-3/+4
This patch adds the support for displaying inlined functions into llvm-objdump. 1) It extends the source variable display support for inlined functions both for ascii and unicode formats. 2) It also introduces a new format called limits-only that only prints a line for the start and end of an inlined function without line-drawing characters.

2023-07-27[llvm-objdump] -d: don't display mapping symbols as labelsFangrui Song1-1/+2
Similar to D96617 for llvm-symbolizer. This patch matches the GNU objdump -d behavior to suppress printing labels for mapping symbols. Mapping symbol names don't convey much information. When --show-all-symbols (not in GNU) is specified, we still print mapping symbols. Note: the `for (size_t SI = 0, SE = Symbols.size(); SI != SE;)` loops needs to iterate all mapping symbols, even if they are not displayed. We use the new field `IsMappingSymbol` to recognize mapping symbols. This field also enables simplification after D139131. ELF/ARM/disassemble-all-mapping-symbols.s is enhanced to add `.space 2`. If `End = std::min(End, Symbols[SI].Addr);` is not correctly set, we would print a `.word`. Reviewed By: jhenderson, jobnoorman, peter.smith Differential Revision: https://reviews.llvm.org/D156190

We pay the one-off boilerplate overhead to create `*Dumper` classes that derive from objdump::Dumper a la llvm-readobj. This has two primary advantages. First, a lot object file format specific code can be moved from llvm-objdump.cpp to *Dump.cpp files. Refactor `printPrivateHeaders` as an example. Second, with the introduction of ELFDumper<ELFT>, we can simplify a few dispatch functions in ELFDump.cpp. In addition, the ObjectFile specific dumpers contains a ObjectFile specific reference so that we can remove a lot of `cast<*ObjectFile>(Obj)`.

This updates the `--function-starts` argument to now accept 3 different modes, `addrs` for just printing the addresses of the function starts (previous behavior), `names` for just printing the names of the function starts, and `both` to print them both side by side. In general if you're debugging function starts issues it's useful to see the symbol name alongside the address. This also mirrors Apple's `dyldinfo -function_starts` command which prints both.

2022-07-14[llvm-objdump] Create fake sections for a ELF core fileNamhyung Kim1-1/+1
The linux perf tools use /proc/kcore for disassembly kernel functions. Actually it copies the relevant parts to a temp file and then pass it to objdump. But it doesn't have section headers so llvm-objdump cannot handle it. Let's create fake section headers for the program headers. It'd have a single section for each segment to cover the entire range. And for this purpose we can consider only executable code segments. With this change, I can see the following command shows proper outputs. perf annotate --stdio --objdump=/path/to/llvm-objdump Differential Revision: https://reviews.llvm.org/D128705

2021-04-14[llvm-objdump] Switch command-line parsing from llvm::cl to OptTableNico Weber1-22/+21
This is similar to D83530, but for llvm-objdump. The motivation is the desire to add an `llvm-otool` symlink to llvm-objdump that behaves like macOS's `otool`, using the same technique the at llvm-objcopy uses to behave like `strip` (etc). This change for the most part preserves behavior. In some cases, it increases compatibility with GNU objdump a bit. For example, the long options now require two dashes, and the long options taking arguments for the most part now require a `=` in front of the value. Exceptions are flags where tests passed the value separately, for these the separate form is kept as an alias to the = form. The one-letter short form args are now joined or separate and long longer accept a =, which also matches GNU objdump. cl::opt<>s in libraries now have to be explicitly plumbed through. This patch does that for --x86-asm-syntax=, but there's hope that we can remove that again. Differential Revision: https://reviews.llvm.org/D100433

2020-04-06[llvm-objdump][XCOFF] Use symbol index+symbol name + storage mapping class ↵diggerlin1-4/+0
as label for -D SUMMARY: For the llvm-objdump -D, the symbol name is used as a label in the disassembly for the specific address (when a symbol address is equal to the virtual address in the dump). In XCOFF, multiple symbols may have the same name, being differentiated by their storage mapping class. It is helpful to print the QualName and not just the name when forming the output label for a csect symbol. The symbol index further removes any ambiguity caused by duplicate names. To maintain compatibility with the binutils objdump, the XCOFF-specific --symbol-description option is added to enable the enhanced format.

2020-04-05[llvm-objdump] Teach `llvm-objdump` dump dynamic symbols.vgxbj1-1/+5
Summary: This patch is to teach `llvm-objdump` dump dynamic symbols (`-T` and `--dynamic-syms`). Currently, this patch is not fully compatible with `gnu-objdump`, but I would like to continue working on this in next few patches. It has two issues. 1. Some symbols shouldn't be marked as global(g). (`-t/--syms` has same issue as well) (Fixed by D75659) 2. `gnu-objdump` can dump version information and *dynamically* insert before symbol name field. `objdump -T a.out` gives: ``` DYNAMIC SYMBOL TABLE: 0000000000000000 w D *UND* 0000000000000000 _ITM_deregisterTMCloneTable 0000000000000000 DF *UND* 0000000000000000 GLIBC_2.2.5 printf 0000000000000000 DF *UND* 0000000000000000 GLIBC_2.2.5 __libc_start_main 0000000000000000 w D *UND* 0000000000000000 __gmon_start__ 0000000000000000 w D *UND* 0000000000000000 _ITM_registerTMCloneTable 0000000000000000 w DF *UND* 0000000000000000 GLIBC_2.2.5 __cxa_finalize ``` `llvm-objdump -T a.out` gives: ``` DYNAMIC SYMBOL TABLE: 0000000000000000 w D *UND* 0000000000000000 _ITM_deregisterTMCloneTable 0000000000000000 g DF *UND* 0000000000000000 printf 0000000000000000 g DF *UND* 0000000000000000 __libc_start_main 0000000000000000 w D *UND* 0000000000000000 __gmon_start__ 0000000000000000 w D *UND* 0000000000000000 _ITM_registerTMCloneTable 0000000000000000 w DF *UND* 0000000000000000 __cxa_finalize ``` Reviewers: jhenderson, grimar, MaskRay, espindola Reviewed By: jhenderson, grimar Subscribers: emaste, rupprecht, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D75756
