2023-05-01libgcc pru: Define TARGET_HAS_NO_HW_DIVIDEDimitar Dimitrov1-0/+3
This patch aligns the configuration to the actual PRU capabilities. It also reduces the size of the affected libgcc functions. For a real-world project using integer arithmetics the savings are significant: Before: text data bss dec hex filename 3688 865 544 5097 13e9 hc-sr04-range-sensor.elf With TARGET_HAS_NO_HW_DIVIDE defined: text data bss dec hex filename 2824 865 544 4233 1089 hc-sr04-range-sensor.elf Execution speed also appears to have improved. The moddi3 function is now executed in half the CPU cycles. libgcc/ChangeLog: * config/pru/t-pru (HOST_LIBGCC2_CFLAGS): Add -DTARGET_HAS_NO_HW_DIVIDE.
