Dear All,
Since a while I see that sdcc rejects code constructs such as:
===
const int constant_expression = (2 ? 3 : 4) + (2 ? 3 : 4);
error 2: Initializer element is not a constant expression (with sdcc 3.8.5
#10914)
===
It used to compile fine with e.g. sdcc 3.6.3 #9791.
In another case an almost identical construct is accepted, but the resulting
code is wrong. Well... it's not there... :)
===
int f2(void)
{
/* Expect 3 + 3 = 6 to be returned. But no code is generated. (3.8.5.
#10914) */
return (2 ? 3 : 4) + (2 ? 3 : 4);
}
141 ; test.c: 57: int f2(void)
142 ;
-----------------------------------------
143 ; function f2
144 ;
-----------------------------------------
010059 145 _f2:
146 ; test.c: 60: return (2 ? 3 :
4) + (2 ? 3 : 4);
147 ; test.c: 62: }
010059 87 [ 5] 148 retf

Both compiled using the STM8 large memory model target. A quick test with
MCS51 large memory model shows the same result for the first issue, but the
second issue does not seem to be present (I see a mov dpl,#0x06 in the
generated code).
In the bugtracker I saw some activity on issues also involving the ternary
operator (e.g. bug 2535), but I'm not sure if these are related.
What do you think? If it looks like a new bug (or bugs), I can file it.
Eric
