Subject: [PATCH] target-s390x: split FPU ops
|
|
|
|
|
|
|
|
Move floating point instructions to fpu_helper.c.
|
|
|
|
|
|
|
|
While exporting some condition code helpers,
|
|
|
|
avoid duplicate identifier conflict with translate.c.
|
|
|
|
|
|
|
|
Remove unused set_cc_nz_f64() in translate.c.
|
|
