I am getting "can't link single-float modules with double-float modules"
linking error, while compiling below code with lp64f.
as per risc-v spec only difference is, for lp64f ABI_FLEN=32 and for lp64d
ABI_FLEN=64.
user@starfive:/tmp$ cat float.c
int main() {
float x = 1.0;
return 1;
}
user@starfive:/tmp$ gcc -g -O -c float.c -mabi=lp64d
user@starfive:/tmp$ gcc -g -O -c float.c -mabi=lp64f
user@starfive:/tmp$ gcc float.c -mabi=lp64d
user@starfive:/tmp$ gcc float.c -mabi=lp64f
