[Valgrind-developers] valgrind: r11435 - trunk/exp-ptrcheck

[<sv...@va...>]

Author: sewardj
Date: 2010-10-12 23:47:09 +0100 (Tue, 12 Oct 2010)
New Revision: 11435

Log:
Changes to make exp-ptrcheck work reasonable on Fedora 14 x86:

* looks_like_a_pointer: x86-linux: halve lower threshold value
  to take account of evident address space randomisation done
  by Fedora 14 on x86

* handle __NR_lgetxattr

* move __NR_mq_* entries to the correct place (tidyup only)
