jcf-write.c (push_long_const): lo, hi: New variables.
2002-04-19 Andrew Haley <aph@redhat.com>
* jcf-write.c (push_long_const): lo, hi: New variables.
Use rshift_double to extract the high part of a 64-bit long.
Use WORD_TO_INT to extract the low part.
* jcf-parse.c (get_constant): CONSTANT_Integer: Use an unsigned
HOST_WIDE_INT for num. Use JPOOL_UINT to get it.
CONSTANT_Double: Use JPOOL_UINT to get both halve of a double.
