[Bug ld/996] Linking requires one open file per object file

It worked for me with the patch in #4 or patch linked from #5.  I tried only
with my test script (increasing the limit to 1000 object files with the same
limit of 25 file descriptors), not with my real application.  strace shows the
right behavior, with the file descriptor high-water mark being around 15.

Thanks guys.

[Bug ld/797] Alignment in empty section changes the output layout

2005-06-09 Thread hjl at lucon dot org 

--- Additional Comments From hjl at lucon dot org  2005-06-09 17:03 ---
The way I looked at

  .text2 :
  {
. = ALIGN(4096);
*(.text2)
  }

it will align .text2 to 4096 byte. If .text2 doesn't exist, the
alignment shouldn't apply. Another one

  .text2 :
  {   
*(.text2)
. = ALIGN(4096);
  }

it pads .text2 to 4096 byte. If .text2 doesn't exist, it shouldn't be padded
to 4096 byte. I would argue that `.' is a special symbol, which shouldn't be
treated as the normal symbol when deciding if a section should be kept.

This bug came back with

http://sourceware.org/ml/binutils/2005-06/msg00197.html

The problem is that now assignment to "dot" will caus the section to be
kept.

I disagree.  An assignment to "dot" inside an output section statement that
moves "dot" has made the section non-empty.  There is no fundamental difference
between an assignment to "dot" with ALIGN on the rhs and other assignments to 
"dot".

If you want to align a section, use

  .text2 ALIGN(4096) :
  {
*(.text2)
  }

This will be removed, and following sections not affected by the alignment, if
all the .text2 input sections are empty.  Aligning both the start and end of a
section also allows the section to be removed:

  .text2 ALIGN (4096) :
  {
*(.text2)
. = ALIGN (4096);
  }

Aligning only the end of a section is a little tricky, but can be accomplished 
with:

  .text3 :
  {
*(.text3)
. = ALIGN (. != 0 ? 4096 : 1);
  }

This also will allow the section to be removed if no non-zero sized .text3 input
sections are linked.
