Re: [PATCH 05/52] rust: Replace uses of {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE

[Arthur Cohen]

Hi,

Sorry about the delay in my answer! The patch looks good to me :) Will 
you push it as part of your patchset?

Kindly,

Arthur

Joseph pointed out "floating types should have their mode,
not a poorly defined precision value" in the discussion[1],
as he and Richi suggested, the existing macros
{FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE will be replaced with a
hook mode_for_floating_type.  To be prepared for that, this
patch is to replace use of {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE
in rust with TYPE_PRECISION of {float,{,long_}double}_type_node.

gcc/rust/ChangeLog:

        * rust-gcc.cc (float_type): Use TYPE_PRECISION of
        {float,double,long_double}_type_node to replace
        {FLOAT,DOUBLE,LONG_DOUBLE}_TYPE_SIZE.
