2022-09-19Fix PR target/99184: Wrong cast from double to 16-bit and 32-bit intsGeorg-Johann Lay1-50/+0
this patch fixed PR target/99184 which incorrectly rounded during 64-bit (long) double to 16-bit and 32-bit integers. The patch just removes the respective roundings from libf7-asm.sx::to_integer and ::to_unsigned. Luckily, LibF7 does nowhere use respective functions internally, the only user is in libf7.c::f7_exp which reads f7_round (qq, qq); int16_t q = f7_get_s16 (qq); so that f7_get_s16() operates on an already rounded value, and therefore this code works unaltered with or without rounding in to_integer. PR target/99184 libgcc/config/avr/libf7/ * libf7-asm.sx (to_integer, to_unsigned): Don't round 16-bit and 32-bit integers.
