2002-03-05 Tom Tromey <tromey@redhat.com>
* config/stormy16/stormy16.h (DWARF_LINE_MIN_INSTR_LENGTH):
Define.
2002-03-05 Nick Clifton <nickc@cambridge.redhat.com>
* config/stormy16/stormy16.md ("*eqbranchsi"): Remove '+' on
operand 2.
("*ineqbranchsi"): Likewise.
2002-03-05 Andrew Haley <aph@cambridge.redhat.com>
* config/stormy16/stormy16.c (xstormy16_expand_prologue): Delete
mem_fake_push_rtx. Instead construct a SEQUENCE to show the
register store followed by a stack increment.
2002-03-05 Chris Moller <cmoller@redhat.com>
* config/stormy16/stormy16.c (REG_NEEDS_SAVE): added a term
to inhibit saving CARRY_REGS.
* config/stormy16/stormy16.c (xs_hi_general_operand):
added predicate to detect and error-out on out-of-range
const_ints for movhi.
* config/stormy16/stormy16.md (movhi): use
xs_hi_general_operand.
* config/stormy16/stormy16.c (xstormy16_expand_prologue):
added a check for local vbl size overflow.
* config/stormy16/stormy16.c (xs_hi_nonmemory_operand):
added predicate to detect and error-out on out-of-range
const_ints for addhi and subhi.
* config/stormy16/stormy16.md (addhi3, addchi4, addchi5,
subhi3, subchi4, subchi5): used xs_hi_nonmemory_operand.
* config/stormy16/stormy16.c (xstormy16_legitimate_address_p):
add a term to accept PRE_MODIFY addresses.
* config/stormy16/stormy16.c (xstormy16_expand_move):
add code to expand PRE_MODIFY addresses to an add followed
by a move.
