Hi,
For this (reduced) test case
extern int x, y, z;
void foo(void);
void bar(void);
void blah(void);
void test (void)
{
int flag = 0;
flag = ((x && y) || z);
if (flag && x && y) {
bar();
}
}
I expected gcc -Os (x86_64, if it matters) to generate code equivalent to
if (x &

Now you can benefit from our network of over 2,400 lenders and fund managers.
If you have a scenario (comm. or residential) that you can't seem to get funded
using your regular channels, why not send it to us and we'll try and match your
deal to a lender who can get it closed. Our lenders don't

Hi All,
I am porting gcc for an internal processor and I am having some issues with
math instructions. Our processor uses two operands for math instructions which
are usually of the form OP0 = OP0 + OP1. The RTL pattern (for addm3) in gcc
uses the form OP0 = OP1 + OP2. I understand that gcc

Hi Nathan,
Thanks for your advice. I retooled the addhi3 sequence to look like this:
(define_expand "addhi3"
[(set (match_operand:HI 0 "snap_mem_or_reg""+a,m")
(plus:HI (match_operand:HI 1 "snap_mem_or_reg" "%0,0")
(match_operand:HI 2 "general_operand" "aim,aim")))]
""
""
)
