2022-03-16binutils/readelf: build against msgpack, dump NT_AMDGPU_METADATA note contentsSimon Marchi
The AMDGPU HSA OS ABI (code object v3 and above) defines the NT_AMDGPU_METADATA ELF note [1]. The content is a msgpack object describing, among other things, the kernels present in the code object and how to call them. I think it would be useful for readelf to be able to display the content of those notes. msgpack is a structured format, a bit like JSON, except not text-based. It is therefore possible to dump the contents in human-readable form without knowledge of the specific layout of the note. Add configury to binutils to optionally check for the msgpack C library [2]. Add There is a new --with{,out}-msgpack configure flag, and the actual library lookup is done using pkg-config. If msgpack support is enabled, dumping a NT_AMDGPU_METADATA note looks like: $ readelf --notes amdgpu-code-object Displaying notes found in: .note Owner Data size Description AMDGPU 0x0000040d NT_AMDGPU_METADATA (code object metadata) { "amdhsa.kernels": [ { ".args": [ { ".address_space": "global", ".name": "out.coerce", ".offset": 0, ".size": 8, ".value_kind": "global_buffer", }, <snip> If msgpack support is disabled, dump the contents as hex, as is done with notes that are not handled in a special way. This allows one to decode the contents manually (maybe using a command-line msgpack decoder) if really needed. [1] https://llvm.org/docs/AMDGPUUsage.html#code-object-metadata [2] https://github.com/msgpack/msgpack-c/tree/c_master binutils/ChangeLog: * Makefile.am (readelf_CFLAGS): New. (readelf_LDADD): Add MSGPACK_LIBS. * Makefile.in: Re-generate. * config.in: Re-generate. * configure: Re-generate. * configure.ac: Add --with-msgpack flag and check for msgpack using pkg-config. * readelf.c: Include msgpack.h if HAVE_MSGPACK. (print_note_contents_hex): New. (print_indents): New. (dump_msgpack_obj): New. (dump_msgpack): New. (print_amdgpu_note): New. (process_note): Handle NT_AMDGPU_METADATA note contents.

Handle the NT_AMDGPU_METADATA note, which is described here: https://llvm.org/docs/AMDGPUUsage.html#code-object-v3-note-records As of this patch, just print out the name, not the contents, which is in the msgpack format. binutils/ChangeLog: * readelf.c (get_amdgpu_elf_note_type): New.

2022-03-16binutils/readelf: decode AMDGPU-specific e_flagsSimon Marchi
Decode and print the AMDGPU-specific fields of e_flags, as documented here: https://llvm.org/docs/AMDGPUUsage.html#header That is: - The specific GPU model - Whether the xnack and sramecc features are enabled The result looks like: - Flags: 0x52f + Flags: 0x52f, gfx906, xnack any, sramecc any The flags for the "HSA" OS ABI are properly versioned and documented on that page. But the NONE, PAL and MESA3D OS ABIs are not well documented nor versioned. Taking a peek at the LLVM source code, we see that they encode their flags the same way as HSA v3. For example, for PAL: https://github.com/llvm/llvm-project/blob/c8b614cd74a92d85936aed5ac7c642af75ffdc29/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp#L601 So for those other OS ABIs, we read them the same as HSA v3. binutils/ChangeLog: * readelf.c: Include elf/amdgcn.h. (decode_AMDGPU_machine_flags): New. (get_machine_flags): Handle flags for EM_AMDGPU machine type. include/ChangeLog: * elf/amdgcn.h: Add EF_AMDGPU_MACH_AMDGCN_* and EF_AMDGPU_FEATURE_* defines.

2022-03-15Fix bug in dwarf-mode.elTom Tromey
I noticed that, occasionally, dwarf-mode would think that the objdump subprocess was still running after it had clearly exited. I managed to reliably reproduce this today and learned that a process sentinel is not guaranteed to be run with the current buffer set to the process buffer. This patch fixes the problem. I've bumped the version number of dwarf-mode.el to make it easier to install for users who already have an earlier one installed. I'm checking this in. 2022-03-15 Tom Tromey <tromey@adacore.com> * dwarf-mode.el: Now 1.7. (dwarf--sentinel): Switch to the process buffer.

2022-03-06MIPS/opcodes: Fix alias annotation for branch instructionsMaciej W. Rozycki
Correct issues with INSN2_ALIAS annotation for branch instructions: - regular MIPS BEQZ/L and BNEZ/L assembly instructions are idioms for BEQ/L and BNE/L respectively with the `rs' operand equal to $0, - microMIPS 32-bit BEQZ and BNEZ assembly instructions are idioms for BEQ and BNE respectively with the `rt' operand equal to $0, - regular MIPS BAL assembly instruction is an idiom for architecture levels of up to the MIPSr5 ISA and a machine instruction on its own from the MIPSr6 ISA up. Add missing annotation to BEQZ/L and BNEZ/L accordingly then and add a new entry for BAL for the MIPSr6 ISA, correcting a disassembly bug: $ mips-linux-gnu-objdump -m mips:isa64r6 -M no-aliases -d bal.o bal.o: file format elf32-tradlittlemips Disassembly of section .text: 00000000 <foo>: 0: 04110000 0x4110000 ... $ Add test cases accordingly.
