sys/sdt.h fp constraints cont'd, x86-64 edition
|
||
|
|
||
|
It appears that various versions of gcc continue to show signs of
|
||
|
confusion at our newly offered asm-operand alternatives for floating
|
||
|
point sdt.h marker parameters.
|
||
|
|
||
|
e.g., https://bugzilla.redhat.com/show_bug.cgi?id=2028798
|
||
|
|
||
|
We may need to restore previous constraints broadly, forcing the
|
||
|
compiler to plop floating point parameters into integer storage.
