varasm.c (output_constant_pool): Use floor_log2 instead of exact_log2 for ASM_OUTPUT_ALIGN.
Thu Jan 21 14:13:31 1999 Vladimir N. Makarov <vmakarov@cygnus.com>
* varasm.c (output_constant_pool): Use floor_log2 instead of
exact_log2 for ASM_OUTPUT_ALIGN.
* stor-layout.c (layout_type): Do machine-dependent extra alignment.
* emit-rtl.c (operand_subword): Handle case when a subword outside
the operand.
* tm.texi (ROUND_TYPE_{SIZE,ALIGN}): More accurate descriptions of
the macros.
