1.10 +# This perl script checks for correct memory function usage in ICU library code.
1.11 +# It works with Linux builds of ICU using gcc.
1.12 +#
1.13 +# To run it,
1.14 +# 1. Build ICU
1.15 +# 2. cd icu/source
1.16 +# 3. perl ICUMemCheck.pl
1.17 +#
1.18 +# All object files containing direct references to C or C++ runtime library memory
1.19 +# functions will be listed in the output.
1.20 +#
1.21 +# For ICU 3.6, the expected output is
1.22 +# common/uniset.o U operator delete(void*)
1.23 +# common/unifilt.o U operator delete(void*)
1.24 +# common/cmemory.o U malloc
1.25 +# common/cmemory.o U free
1.26 +# i18n/strrepl.o U operator delete(void*)
1.27 +# layout/LEFontInstance.o U operator delete(void*)
1.28 +# layout/LEGlyphStorage.o U operator delete(void*)
1.29 +# layout/LayoutEngine.o U operator delete(void*)
1.30 +#
1.31 +# cmemory.c Expected failures from uprv_malloc, uprv_free implementation.

1.43 +# The problem destructors all are for mix-in style interface classes.
1.44 +# These classes can not derive from UObject or UMemory because of multiple-inheritance
1.45 +# problems, so they don't get the ICU memory functions. The delete code
1.46 +# in the destructors will never be called because stand-alone instances of
1.47 +# the classes cannot exist.
