- Subject: [rfa:sparc] Remove write_fp() from sparc-tdep.c
Hello,
The attached deletes the write_fp() function from the sparc-tdep.c code.
Ok?
Once this is in, I'll commit the other patch that simply deletes
write_fp() from the architecture vector.

* sparc-tdep.c (sparc64_write_fp): Delete.
(sparc_push_dummy_frame): Replace write_fp call with code to store
the FP directly.
(sparc_gdbarch_init): Do not initialize write_fp.
