Hi,
For 64-bit Android, long double is 128-bit IEEE-754 floating point type.
This patch adds -mlong-double-128 to i386 and makes it default for 64-bit
Bionic. I only added MASK_LONG_DOUBLE_128. I made -mlong-double-128,
-mlong-double-64 and -mlong-double-80 negate each other so that the
last one on command line wins. It os OK since we don't support
-mlong-double-xxx in target attribute. I added some testcases to verify
it works correctly. OK for trunk?
Thanks.
H.J.
