Hi Maintainers,
PFA, the patch that enables support for the next generation AMD Zen CPU via
-march=znver2.
As of now, znver2 is using the same costs and scheduler descriptions written
for znver1.
We will update scheduler descriptions and costing for znver2 later as we get
more information.

The attached patch implements an RTL pass which splits generated FMA

The pass is enabled for Zen and done when we find it is profitable to split the
FMA.
On Zen, we found that for a tight loop with FMA (reduction) operation as show

Hi Uros,
While debugging GCC to see if cost of multiplication for DI mode is set
correctly for znver1 target.
I found that the order of cost table insertion is wrong for znver1 and it
worked because btver2 had same cost for multiply .
The patch corrects the mistake I made.

Costs and tunings are copied from bdver4, but we will be adjusting them later

Hi Richard,
For Aarch64 target, I was trying to vectorize the expression
"arr[i]=arr[i]*4;" via vector shifts instructions since they don't have
vector mults.
unsigned long int __attribute__ ((aligned (64)))arr[100];
int i;
#if 1
void test_vector_shifts()
{
for(i=0; i<=99;i++)
your case.
Regards,
Venkat.

I got around ~12% gain with -Ofast -mcpu=cortex-a57.

Changing to "1 step for float" and "2 steps for double" gives better gains now
for gromacs on cortex-a57.

Hi,
If I understand correct, current implementation replaces
fdiv
fsqrt
by
frsqrte
for i=0 to 3
fmul
frsqrts
fmul
So I think gains depends latency of frsqrts insn.
I see patch has patterns for vector versions of frsqrts, but does not enable
them?
Regards,
Venkat.

Hi,
is there a plan to support -mrecip=rsqrt for Aarch64?

Hi Maintainers,
This patch adds support for new MONITORX and MWAITX instructions and also
enables them via builtins.
The ISA is enabled by new -mmwaitx option and is available for AMD bdver4
target (-march=bdver4).
MONITORX and MWAITX implements same functionality as old MONITOR and MWAIT.
