mpfr-longlong.h: Fix obsolete ARC asm constraints
|
|
|
|
This patch replaces obsolete ARC "J" asm constraint with
|
|
up-to-date "Cal" constraint.
|
|
The patch should be applied to upstream "mpfr" library and
|
|
after that it should be removed from buildroot as soon as
|
|
mpfr version with current fix will come up.
