Hi Kev, I'm glad to hear llvm-objdump is getting attention. I'm unclear on how much output specialization one could (or should) do for ELF vs. Mach-O. If you're game, let's compare an example: $ cat labeltest.s .text foo: nop bar: bum: nop jmp bar jmp bum jmp baz nop baz: nop Assembling for x86 and llvm-objdump'ing, i get $ llvm-mc

At least for now, I don’t expect it to become all that unwieldy. Any behavioral differences should be easily separable into different classes and source files. If as things progress it becomes obvious that there’s really not much of anything in common other than the general nature of the tools, it’s easy to split them apart. -Jim > On Dec 1, 2014, at 5:20 PM, Steve King <steve at

OK. Let's try a specific example: At least for ELF files, GNU objdump prints operand values in hex. AFAIK, hex is not just the default, but the only choice. On the other hand, llvm-objdump prints operand values in decimal and ignores the --print-imm-hex option for ELF. How about a patch to print operands in hex for ELF? Good place to start?

Hey folks, This is great to see more interest on the supporting tools like objdump and such. I very much agree that bringing llvm-objdump up to feature parity (to start with) compared to both otool(1) and objdump(1) is a great goal. The default output formatting is easy enough to get right by having it be controlled by the container format (otool style for macho, objdump style for ELF). Kevin’s

Hello LLVM, Previously, some folks wanted llvm-objdump to behave more like GNU objdump. This could encompass both command line options and output format. Such a change helps developers already familiar with GNU tools and allows re-use of Perl scripts or other automation expecting to see GNU style dumps. Is moving llvm-objdump toward GNU objdump the general preference? And what about otools

Hello Tim, Rafael, Renato and llvmdev, I’m working to get llvm-objdump handle both arm and thumb disassembly from the same object file similarly to how darwin’s otool(1) works. And I’m looking for implementing direction. I spoke to Jim Grosbach about some ideas and he suggested I send out and email about some of the possibilities. Since none of the ones I could think of are pretty he thought

In creating a test case for a bug fix in llvm-objdump, I noticed that it differs in its output of pc-relative immediates from objdump: [secdev:/tmp] s$ cat a.s main: jmp .LBL0 .LBL0: ret [secdev:/tmp] s$ llvm-mc -filetype=obj a.s > a.o [secdev:/tmp] s$ objdump -d a.o |tail -n 2 0: eb 00 jmp 2 <main+0x2> 2: c3 retq

Hence my question. I dont know if there is any way to change this behavior. Looks like a bug to me so far. It isn't. It's just created some assembly which, when assembled, may

I've made a change to llvm-objdump and feel uncomfortable checking it in without a test case. Where do the "make check" tests for tools like llvm-objdump go? Worse comes to worse, I'll stick it in test/MC/Mips since it is there I need the change for other Mips/MC tests.

Hi folks, As part of our build, the Tock project uses remap-path-prefix [1] to create a reproducible build. This means that the paths inside of built artifacts are not full source paths. When we later attempt to produce a listings file, the source mapping fails. The result is many copies of this recently merged warning [2]: llvm-objdump: warning:

Hello, $ objdump -h # displays info about all below sections.... Sections: Idx Name Size VMA LMA File off Algn While, $ llvm-objdump -h # only displays subset of info... Sections: Idx Name Size Address Type Using '--show-lma' could get VMA and LMA details. Can you suggest options to print 'File off' and

Hi, We are trying to use LLVM API to programmatically obtain a list of relocations in an ELF file. The way we are doing this is exactly as llvm-objdump does it: we are iterating through sections and in each section we are iterating over relocations (see PrintRelocations() function at https://llvm.org/svn/llvm-project/llvm/trunk/tools/llvm-objdump/llvm-objdump.cpp). However, it does not give us

# Summary As a consequence of comparing the RISC-V LLVM MC assembler to the RISC-V GNU assembler I've noticed that a number of targets have quite different handling for pc-relative jumps/branches with immediate integer operands in llvm-mc vs GNU as. I'll admit that this isn't likely to occur in hand-written code (as you'd almost always prefer to use a label), but thought it was

Kevin Enderby added those symbol uses in r270491. It has a cmake feature test, and all the uses of those symbols appear bracketed in HAVE_LIBXAR, so I don't know what went wrong for you.

Hi all, I try to compile my package kml and I get the message Warning in read_symbols_from_dll(so,rarch): this requires 'objdump.exe' to be on the PATH I check 'Writing R Extensions' but I did not find any reference to this error. Does someone know how to fix that? Thank you very much for your help. Christophe
