From c3f72de4f53bc3e5f13762633d78d8a7efb8dd79 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Tue, 6 Apr 2021 19:03:35 +0930 Subject: PowerPC disassembly of pcrel references This adds some annotation to Power10 pcrel instructions, displaying the target address (ie. pc + D34 field) plus a symbol if there is one at exactly that target address. pld from the .got or .plt will also look up the entry and display it, symbolically if there is a dynamic relocation on the entry. include/ * dis-asm.h (struct disassemble_info): Add dynrelbuf and dynrelcount. binutils/ * objdump.c (struct objdump_disasm_info): Delete dynrelbuf and dynrelcount. (find_symbol_for_address): Adjust for dynrelbuf and dynrelcount move. (disassemble_section, disassemble_data): Likewise. opcodes/ * ppc-dis.c (struct dis_private): Add "special". (POWERPC_DIALECT): Delete. Replace uses with.. (private_data): ..this. New inline function. (disassemble_init_powerpc): Init "special" names. (skip_optional_operands): Add is_pcrel arg, set when detecting R field of prefix instructions. (bsearch_reloc, print_got_plt): New functions. (print_insn_powerpc): For pcrel instructions, print target address and symbol if known, and decode plt and got loads too. gas/ * testsuite/gas/ppc/prefix-pcrel.d: Update expected output. * testsuite/gas/ppc/prefix-reloc.d: Likewise. * gas/testsuite/gas/ppc/vsx_32byte.d: Likewise. ld/ * testsuite/ld-powerpc/inlinepcrel-1.d: Update expected output. * testsuite/ld-powerpc/inlinepcrel-2.d: Likewise. * testsuite/ld-powerpc/notoc2.d: Likewise. * testsuite/ld-powerpc/notoc3.d: Likewise. * testsuite/ld-powerpc/pcrelopt.d: Likewise. * testsuite/ld-powerpc/startstop.d: Likewise. * testsuite/ld-powerpc/tlsget.d: Likewise. * testsuite/ld-powerpc/tlsget2.d: Likewise. * testsuite/ld-powerpc/tlsld.d: Likewise. * testsuite/ld-powerpc/weak1.d: Likewise. * testsuite/ld-powerpc/weak1so.d: Likewise. --- include/dis-asm.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include/dis-asm.h') diff --git a/include/dis-asm.h b/include/dis-asm.h index f3562fa..e8b42b0 100644 --- a/include/dis-asm.h +++ b/include/dis-asm.h @@ -114,6 +114,10 @@ typedef struct disassemble_info /* Set if the user has requested wide output. */ #define WIDE_OUTPUT (1u << 28) + /* Dynamic relocations, if they have been loaded. */ + arelent **dynrelbuf; + long dynrelcount; + /* Use internally by the target specific disassembly code. */ void *private_data; -- cgit v1.1
