Hi,
I have encountered issues that arise from the setting of the C and V flags when trying to use conditional branches (B.HI and B.LE)

The sequence
movz x1, #36
movz x2, #54
subs x5, x1, x2
b.LE lse
does not work properly. The V flag is set but 36-54 = -18 is not a signed overflow.

The sequence
movz x1, #54
movz x2, #36
subx x5, x1, x2
b.GT gtr
does not work properly as 54-36=18 does not set the carry bit as it should.

In the setVflag(long result, long op1, long op2) {
replacing

with
Vflag = (((long) op1 & 0x80000000L) == ((long) op2 & 0x80000000L)) && ((long) result != (long)op1;
may work but I don't have the experience with GWT projects to rebuild.

I haven't had a chance to figure the issue with setting the C flag in the other scenario.

Thanks,
Dave
