Thanks. The head now works again.

Can this patch be applied to the active release branches? 

>From an earlier comment of mine:

works - binutils 2.21.1 with no patches
broken - binutils 2.22 with no patches

If there are to be more 2.22 patches, this should be applied to that branch.

[Bug gas/14017] New: Bug in symbol arithmetic

2012-04-24 Thread makhaloff at gmail dot com 
http://sourceware.org/bugzilla/show_bug.cgi?id=14017

 Bug #: 14017
   Summary: Bug in symbol arithmetic
   Product: binutils
   Version: 2.23 (HEAD)
Status: NEW
  Severity: normal
  Priority: P2
 Component: gas
AssignedTo: unassig...@sourceware.org
ReportedBy: makhal...@gmail.com
Classification: Unclassified


Created attachment 6364
  --> http://sourceware.org/bugzilla/attachment.cgi?id=6364
Patch to fix this bug

I got error on this code:

.text
NULL:
PS_8K = 0x40   
OFFSET = (System1 - NULL)
S = (OFFSET + PS_8K)
movl $2,S
 .org 0x2000
System1:

S will be equal 0x40. But actual value should be 0x2040.

The reason is as follows:
* gas/read.c (pseudo_set): Fixed x=undef+const case (expr_sections is undefined
at this time also)

Example and patch are attached.

[Bug gas/14019] New: Potential bug with on stack allocated variable

2012-04-24 Thread makhaloff at gmail dot com 
http://sourceware.org/bugzilla/show_bug.cgi?id=14019

 Bug #: 14019
   Summary: Potential bug with on stack allocated variable
   Product: binutils
   Version: 2.23 (HEAD)
Status: NEW
  Severity: normal
  Priority: P2
 Component: gas
AssignedTo: unassig...@sourceware.org
ReportedBy: makhal...@gmail.com
Classification: Unclassified


gas/read.c:1771

  if (line_label != NULL)
{
  expressionS exp;
  exp.X_op = O_symbol;
  exp.X_add_symbol = sym;
  exp.X_add_number = 0;
  symbol_set_value_expression (line_label, &exp);
  symbol_set_frag (line_label, &zero_address_frag);
  S_SET_SEGMENT (line_label, expr_section);
}

line_label is global, exp is local on stack allocated.
I might be reason of bug later.

Perhaps I wrong?

This is not a bug, as you can see by looking at the function
symbol_set_value_expression.
