In our context, some construct has decided that we don't support
|
|
XF mode (which is not true for the architecture, in general, as
|
|
this patch supports, but is sufficient for our strange environment).
|
|
|
|
Backport of commit 43ccb7e445329dd9557b42e7289a87a8071ab0f7.

|
[PATCH] libgcc: Enable XF mode conversions to/from DFP modes only if
|
|
supported
|
|
|
|
Some targets do not support XF mode (eg AArch64), so don't build the
|
|
corresponding to/from DFP modes convertion routines if
|
|
__LIBGCC_HAS_XF_MODE__ is not defined.
