# DP: Fix --with-long-double-128 for sparc32 when defaulting to 64-bit.
3
On sparc, the --with-long-double-128 option doesn't change anything for
4
a 64-bit compiler, as it always default to 128-bit long doubles. For
5
a 32/64-bit compiler defaulting to 32-bit this correctly control the
6
size of long double of the 32-bit compiler, however for a 32/64-bit
7
compiler defaulting to 64-bit, the built-in specs force the
8
-mlong-double-64 option. This makes the option useless in this case.
10
The patch below fixes that by removing the -mlong-double-64 from the
11
built-in spec, using the default instead.

* config/sparc/linux64.h (CC1_SPEC): When defaulting to 64-bit,
18
don't force -mlong-double-64 when -m32 or -mv8plus is given.
