In Tasmota I realized the following floating point function are in precious IRAM:
This PR adds a
#define FP_IN_IROMto move floating point function out of IRAM to IROM.*f2.o,*f3.o:floatanddoublefunctions*fsi.o: fp to int*fdi.o: fp to long*ifs.o: int to fp*ids.o: long to fpIn Tasmota, the only functions from
libgccremaining in IRAM are:__modsi3(integer modulus) and__ashrdi3(bit shifting).The net result is reducing IRAM usage by 1040 bytes.
