# reuse-exe

Tells the compiler to speed up Field Programmable Gate Array (FPGA) target compile time by reusing a previously compiled FPGA hardware image. This option is useful only when compiling for hardware. This content is specific to DPC++.

## Syntax

Linux: | -reuse-exe=exe-filename

Windows: | -reuse-exe=exe-filename

## Arguments

exe-filename | Is a previously compiled SYCL* binary.

## Default

OFF | There is no potential compile-time speed up by reusing the executable for the FPGA target.

## Description

This option tells the compiler to speed up FPGA target compile time by reusing a previously compiled FPGA hardware image. This option is useful only when compiling for hardware.

It lets you minimize or avoid long Intel® Quartus® Prime Software compile times for FPGA targets when the device code is unchanged.
