Still broken for me with current binutils git trunk:

(Switched alternatives back to use /usr/bin/ld.bfd.)  Built
~/binutils/trunk/inst/bin/ld.gold --version "GNU gold (GNU Binutils
2.24.51.20131031) 1.11".

  $ g++ -shared -fPIC -o lib1.so lib1.cc
  $ g++ -shared -fPIC -c lib2.cc
  $ g++ -### -shared -fPIC -o lib2.so -Wl,--version-script,lib2.ver lib2.o -L.
-l1
  # replacing collect2 in the linker command line:
  $ ~/binutils/trunk/inst/bin/ld.gold --build-id --no-add-needed --eh-frame-hdr
"--hash-style=gnu" -m elf_x86_64 -shared -o lib2.so

[Bug gold/16108] New: gold .gdb_index version 7 support is missing

2013-10-31 Thread naesten at gmail dot com
https://sourceware.org/bugzilla/show_bug.cgi?id=16108

Bug ID: 16108
   Summary: gold .gdb_index version 7 support is missing
   Product: binutils
   Version: 2.25 (HEAD)
Status: NEW
  Severity: normal
  Priority: P2
 Component: gold
  Assignee: ian at airs dot com
  Reporter: naesten at gmail dot com
CC: ccoutant at google dot com

Somehow, despite having been mentioned in some GDB bugs and in GDB code, gold
support for .gdb_index version 7 doesn't seem to be in the actual repository.

It would be nice if someone could track down the patch(es) and get them
committed.

[Bug gas/16109] New: Incorrect listing (single line comment after multiline one causes line mis-alignment)

2013-10-31 Thread makhaloff at gmail dot com
https://sourceware.org/bugzilla/show_bug.cgi?id=16109

Bug ID: 16109
   Summary: Incorrect listing (single line comment after multiline
one causes line mis-alignment)
   Product: binutils
   Version: 2.23
Status: NEW
  Severity: normal
  Priority: P2
 Component: gas
  Assignee: unassigned at sourceware dot org
  Reporter: makhaloff at gmail dot com

I have a simple example:

/*
*/#
nop
nop

There are some assembler outputs:

$ arm-linux-gnueabi-as -ahl 1.s
ARM GAS  1.spage 1


   1/*
   2  A0E1  */#
   3nop
   4 0004 A0E1  nop
   5 


$ mips-linux-as -ahl 1.s
GAS LISTING 1.s page 1


   1/*
   2    */#
   3nop
   4 0004   nop
   5 0008  
   5   


After some modification:


/*
*/
nop
nop

listing is corect.

$ arm-linux-gnueabi-as -ahl 1.s
ARM GAS  1.spage 1


   1/*
   2*/
   3  A0E1  nop
   4 0004 A0E1  nop
   5
