[perl5.git] / asan_ignore

# This file intended to be used with clang as
#
#  clang -fsanitize=foo -fsanitize-blacklist=`pwd`/asan_ignore

# It lists those files / functions that clang's Address Sanitizer should
# ignore.

# See http://clang.llvm.org/docs/SanitizerSpecialCaseList.html.


# The pp functions used under 'use integer' shouldn't warn about
# integer overflow etc.
#
# Unfortunately there doesn't seem to be any way to disable just specific
# errors (i.e. the integer overflow ones). The manual implies that you can
# suffix with =foo for a "tool-specific category", but neither =undefined
# nor =signed-integer-overflow worked.

fun:Perl_pp_i_*

# Perl's << is defined as using the underlying C's << operator, with the
# same undefined behaviour for shifts greater than the word size.
# (UVs normally, IVs with 'use integer')

fun:Perl_pp_left_shift

# this function numifies the field width in eg printf "%10f".
# It has its own overflow detection, so don't warn about it
