At present, the building of ExtensionSubtables.cpp produces a warning:
../../../src/share/native/sun/font/layout/ExtensionSubtables.cpp:57:31:
warning: dereferencing type-punned pointer will break strict-aliasing rules
[-Wstrict-aliasing]
due to this code:
// read a 32-bit value that might only be 16-bit-aligned in memory
#define READ_LONG(code) (le_uint32)((SWAPW(*(le_uint16*)&code) << 16) +
SWAPW(*(((le_uint16*)&code) + 1)))
where code is a le_uint32.
This can be avoided by setting -fno-strict-aliasing, as done in this webrev:
http://cr.openjdk.java.net/~andrew/no-strict-aliasing/
making the code safer in the process.
Ok for jdk8? If so, can I have a bug ID for this please?
Thanks,
