[PATCH v2 13/45] target/arm: Make VFP_CONV_FIX macros take separate floa


From: Peter Maydell
Subject: [PATCH v2 13/45] target/arm: Make VFP_CONV_FIX macros take separate float type and float size
Date: Fri, 28 Aug 2020 19:33:22 +0100

Currently the VFP_CONV_FIX macros take a single fsz argument for the
size of the float type, which is used both to select the name of
the functions to call (eg float32_is_any_nan()) and also for the
type to use for the float inputs and outputs (eg float32).

Separate these into fsz and ftype arguments, so that we can use them
for fp16, which uses 'float16' in the function names but is still
passing inputs and outputs in a 32-bit sized type.
