From e6cf44ee5617b7afb4aa3f6a010b8718004bd1a9 Mon Sep 17 00:00:00 2001 From: Andreas Schwab Date: Mon, 10 Jan 2005 09:54:50 +0000 Subject: [PATCH] binutils/: * configure.in: Don't define SKIP_ZEROES. * configure: Regenerate. * objdump.c (disassemble_data): Set skip_zeroes and skip_zeroes_at_end in disasm_info to defaults. (DEFAULT_SKIP_ZEROES): Rename from SKIP_ZEROES and always define. (DEFAULT_SKIP_ZEROES_AT_END): Rename from SKIP_ZEROES_AT_END and always define. (disassemble_bytes): Use skip_zeroes and skip_zeroes_at_end from objdump_disasm_info. include/: * dis-asm.h (struct disassemble_info): Add skip_zeroes and skip_zeroes_at_end. opcodes/: * disassemble.c (disassemble_init_for_target) : Set skip_zeroes to 16. : Set skip_zeroes to 32. --- include/ChangeLog | 5 +++++ include/dis-asm.h | 12 ++++++++++++ 2 files changed, 17 insertions(+) diff --git a/include/ChangeLog b/include/ChangeLog index 198570979..c4fab4bbf 100644 --- a/include/ChangeLog +++ b/include/ChangeLog @@ -1,3 +1,8 @@ +2005-01-10 Andreas Schwab + + * dis-asm.h (struct disassemble_info): Add skip_zeroes and + skip_zeroes_at_end. + 2004-12-11 Ben Elliston * fibheap.h (struct fibnode): Only use unsigned long bitfields diff --git a/include/dis-asm.h b/include/dis-asm.h index aa8e2b508..be54263a7 100644 --- a/include/dis-asm.h +++ b/include/dis-asm.h @@ -159,6 +159,18 @@ typedef struct disassemble_info { Normally one, but some DSPs have byte sizes of 16 or 32 bits. */ unsigned int octets_per_byte; + /* The number of zeroes we want to see at the end of a section before we + start skipping them. */ + unsigned int skip_zeroes; + + /* The number of zeroes to skip at the end of a section.
