[Bug binutils/1198] Segfault when executing objdump on a special file...

--- Comment #3 from Lionel Debroux  ---
I had completely forgotten about this bug report posted several days after I
first installed Linux on my computer :)

In the meantime:
* I switched to Linux near-full-time in 2006, for both home and work usage.
This computer cannot easily run VirtualBox VMs anymore. The simplest way to
perform native Windows builds and tests is now to use another computer from
work, which could take a bit of time, possibly not before the end of next week.

* I co-created the GCC4TI development environment out of the aforementioned
TIGCC. Among the various bugfixes and improvements we made, the following ones
are relevant to this discussion:
1) the custom build scripts do not delete ar, objcopy, objdump, size and strip
any longer (better having incomplete tools for expert usage than none at all
!);
2) GCC4TI's gcc and binutils use a program prefix, so that they don't collide
with system gcc and binutils;
3) the local patch to binutils was expanded one hack-ish hunk, so as to mask
out the offending flag and make the binutils more usable, though not
necessarily in the way upstream would do it. See the first hunk of 
https://github.com/debrouxl/gcc4ti/blob/4a0341f02f9d95a205b8601ca7be39cd876c5b1c/trunk/tigcc/gcc/gas-2.16-tigcc-patch.diff
.

* binutils, like many other programs, went through rounds of fuzzing and
subsequent bugfixing, while GCC's Windows support further improved.

The problem might therefore well be gone from modern binutils versions, only
testing will tell - but I can't do that today :)

https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=9706b5e627dfae1ab0a2788dda8a2aa5a0e09af7

commit 9706b5e627dfae1ab0a2788dda8a2aa5a0e09af7
Author: H.J. Lu 
Date:   Sun Oct 4 06:14:13 2015 -0700

Change ch_type to Elf_Word in struct Chdr_data<64>

The ch_type field in struct Chdr_data<64>  is 4 bytes, followed by a
4-byte padding.  This change doesn't introduce any functional change
since only the lower 32 bits of the ch_type field are used.

PR gold/19060
* elfcpp.h (Chdr::get_ch_type): Change return type to Elf_Word.
* elfcpp_internal.h (Chdr_data<64>): Change ch_type to 4 bytes
and add ch_reserved.

[Bug binutils/19063] New: objcopy does not set Time/Date field for created pei-x86-64 file

2015-10-04 Thread tsoome at me dot com 
https://sourceware.org/bugzilla/show_bug.cgi?id=19063

Bug ID: 19063
   Summary: objcopy does not set Time/Date field for created
pei-x86-64 file
   Product: binutils
   Version: unspecified
Status: NEW
  Severity: minor
  Priority: P2
 Component: binutils
  Assignee: unassigned at sourceware dot org
  Reporter: tsoome at me dot com
  Target Milestone: ---

GNU objdump (GNU Binutils) 2.25.51.20151004
GNU objcopy (GNU Binutils) 2.25.51.20151004

do create and handle pei files:

/home/tsoome/loader.efi: file format pei-x86-64
/home/tsoome/loader.efi
architecture: i386:x86-64, flags 0x0133:
HAS_RELOC, EXEC_P, HAS_SYMS, HAS_LOCALS, D_PAGED
start address 0xcd80

Characteristics 0x206
   executable
   line numbers stripped
   debugging information removed

Time/Date   Thu Jan  1 03:00:00 1970
Magic   020b(PE32+)
MajorLinkerVersion  2
MinorLinkerVersion  25


there is one minor issue tho (it is there in 2.25.1 at least), this pei-x86-64
file is created with objcopy from elf file and as you see the Time/Date is not
set. Not a big issue, but at least
GNU objcopy 2.17.50 [FreeBSD] 2007-07-03
seems to set time/date properly - it may be freebsd own patch of course.

It is unrelated.  I don't think we should it by default.  Otherwise,
the output of objcopy will be different for each run.

The error message isn't ideal.  But technically it isn't incorrect
since it is how assembler works.  Change it will slow down the assembler.
