-Subject: [commit 2/2] testsuite: code_elim.exp: Fix false FAIL
-
-Hi,
-
-with Fedora 18 x86_64 (Rawhide) there is a false FAIl since:
-2167931cf70f91206efb8b01e848a55d82a347ce is the first bad commit
-Author: Tom Tromey <tromey at redhat.com>
-Date:   Fri May 18 15:31:39 2012 +0000
-http://sourceware.org/bugzilla/show_bug.cgi?id=13907
-
- print &my_global_symbol
--$1 = (int *) 0x804a004
--(gdb) PASS: gdb.base/code_elim.exp: get address of my_global_symbol
-+$1 = (int *) 0x804a004 <completed.5732>
-+(gdb) FAIL: gdb.base/code_elim.exp: get address of my_global_symbol
-
-Nothing really changed, just GDB now prints <completed.5732> and the testcase
-expects either none or <my_global_symbol> suffix.
-
-This is because the two symbol files (their sections .data/.bss) have
-overlapped so GDB chooses randomly which symbol to display.  And since
-Fedora 18 GCC puts there that "completed.5732" symbol.
-
-This may be because add-symbol-file FILE ADDR relocates to ADDR on the .text
-section and leaves other sections at their original place, which is IMO a bit
-unexpected; it is a FAQ people expect more ADDR to be relocation displacement
-(and not relative to .text and not limited to .text).  But this is really
-outside of the scope of this testcase false FAIL.
-
-Checked in.
-
-
-Thanks,
-Jan
