[Pkg-electronics-devel] Bug#981220: gcc-xtensa-lx106: libgcc doesn't contain soft float functions

[Keith Packard]

Package: gcc-xtensa-lx106
Version: 10.2.1-3+8
Severity: normal
X-Debbugs-Cc: keithp at keithp.com

It seems that libgcc built for this toolchain is missing the soft float
emulation functions?

This program fails to link:

cat > test.c << EOF
#include <string.h>
#include <stdio.h>
#include <math.h>

int main(void)
{
        char foo[50];
        double q;
        strcpy(foo, "3.1415");
        sscanf(foo, "%lf", &q);
        return (int) (sin(q) * 100);
}
EOF
