Hello All,
I have found a BUG with loading long long constant:
Here is the source:
void Test(long long l)
{
}
int main()
{
Test(1);
}
And here is the GDB disassembly:
- 0x1166 <main>: mov #2560, SP ;#0x0a00
- 0x116a <main+4>: mov r1, r4 ;
9 Test(1);
- 0x116c <main+6>: mov #1, r12 ;subst r3 with As==01
- 0x116e <main+8>: clr r13 ;
- 0x1170 <main+10>: mov #1, r14 ;subst r3 with As==01 should be clr r14 !
- 0x1172 <main+12>: mov #1, r15 ;subst r3 with As==01 should be clr r15 !
- 0x1174 <main+14>: call #4416 ;#0x1140
- 0x1178 <main+18>: br #0x117c ;
I use msp430-gcc win32 build from 11 Dec 2002.
Thanks,
Oleg.
P.S. Compiling to assembly gives correct asm listing:
/***********************
