From 7ed51401f1fbb8470170c588bf69cc1f690312e5 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 11 Feb 2021 12:27:46 +0000 Subject: [PATCH] target/m68k: Drop use of gdb_get_float64() and ldfq_p() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We used to make a distinction between 'float64'/'float32' types and the 'uint64_t'/'uint32_t' types, requiring special conversion operations to go between them. We've now dropped this distinction as unnecessary, and the 'float*' types remain primarily for documentation purposes when used in places like the function prototypes of TCG helper functions. This means that there's no need for a special gdb_get_float64() function to write a float64 value to the GDB protocol buffer; we can just use gdb_get_reg64(). Similarly, for reading a value out of the GDB buffer into a float64 we can use ldq_p() and need not use ldfq_p().
