Hi,
I've been looking at updating some of the targets to use LRA. On some
targets that have a one register & immediate instruction format (i.e. dest
register and source register are the same), I see errors such as:
error: insn does not satisfy its constraints:
(insn 2 7 5 2 (set (reg/f:SI 12 r12

Hello,
I'm considering attempting a 65816 target but decided it would be a good
idea to start with something simple in order to learn how GCC generate
code. So I created a minimal machine description with just two
instructions (plus the mandatory nop/jump/etc):
(define_mode_iterator INT [QI HI SI

Hi folks!
During asan performance tunning we tried to use VRP and found that it is
path-insensitive and thus suboptimal. In example bellow "i" has VRP
range 0..1000 across whole program but in loop body it is just 0..999.
int a[1000];
void foo ()
{
for (int i=0;i<1000;i++)
a[i] = 0;
