# Errors to suppress by default with XFree86 4.1.0)

# *** And a bunch of other stuff which is completely unrelated
# to X.  The default suppressions are a bit of a mess and could do
# with a good tidying up.

# Format of this file is:
# {
#     name_of_suppression
#     tool_name:supp_kind
#     (optional extra info for some suppression types)
#     caller0 name, or /name/of/so/file.so
#     caller1 name, or ditto
#     (optionally: caller2 name)
#     (optionally: caller3 name)
#  }
#
# For Memcheck, the supp_kinds are:
#
#     Param Value1 Value2 Value4 Value8 Value16 Jump
#     Free Addr1 Addr2 Addr4 Addr8 Addr16
#     Cond (previously known as Value0)
#
# and the optional extra info is:
#     if Param: name of system call param
