4 | Subject: [PATCH 44/47] libgcc: Add knob to use ldbl-128 on ppc | ||
5 | |||
6 | musl does not support ldbl 128 so we can not assume | ||
7 | that linux as a whole supports ldbl-128 bits, instead | ||
8 | act upon configure option passed to gcc and assume no | ||
9 | on musl and yes otherwise if no option is passed since | ||
10 | default behaviour is to assume ldbl128 it does not | ||
11 | change the defaults | ||
