Hi,
correct me if I am wrong, I am doing a port for a new cup arch and I have
set the short type to 8-bit, however as shown below gcc still treat it as
16-bit (HI) ...
I set short type to 8-bit by:
#define SHORT_TYPE_SIZE 8
below is the expender:
main ()
{
volatile long unsigned intD.5 hhD.1332;
volatile short unsigned intD.9 ddD.1331;
*short unsigned intD.9 dd.0_3*;
long unsigned intD.5 hh.1_4;
;; basic block 2, loop depth 0
;; pred: ENTRY
# .MEM_2 = VDEF <.MEM_1(D)>
ddD.1331 ={v} 12;
# VUSE <.MEM_2>
*dd.0_3 ={v} ddD.1331;*
# RANGE [0, 255] NONZERO 0x0000000ff
hh.1_4 = (long unsigned intD.5) dd.0_3;
# .MEM_5 = VDEF <.MEM_2>
hhD.1332 ={v} hh.1_4;
# VUSE <.MEM_5>
return 0;
;; succ: EXIT
}
Partition 1: size 2 align 1
hhD.1332
Partition 0: size 1 align 1
ddD.1331
;; Generating RTL for gimple basic block 2
;; dd ={v} 12;
(insn 6 5 0 (set (mem/v/c:QI (plus:HI (reg/f:HI 18 virtual-stack-vars)
(const_int -3 [0xfffffffd])) [3 ddD.1331+0 S1 A8])
(const_int 12 [0xc])) Testing2.c:41 -1
(nil))
;; _3 ={v} dd;
(insn 7 6 0 *(set (reg:HI 23 [ D.1342 ])*
(zero_extend:HI (mem/v/c:QI (plus:HI (reg/f:HI 18
virtual-stack-vars)
(const_int -3 [0xfffffffd])) [3 ddD.1331
