Subject: [commit] Add BE/LE floating-point type & format tables
Date: Sun, 08 Aug 2004 17:23:00 -0000 [thread overview]
Message-ID: <4116617A.8010601@gnu.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 547 bytes --]
Hello,
This adds tables, indexed by the byte-order, for various be/le
floatformat's and floating-point types. With this, instead of:
if (info.byte_order != BFD_ENDIAN_BIG)
set_gdbarch_float_format
(gdbarch, floatformat_ieee_single_big);
else
set_gdbarch_float_format
(gdbarch, floatformat_ieee_single_little);
[sic], the shorter:
set_gdbarch_float_format
(gdbarch, floatformat_ieee_single[info.byte_order]);
can be used. Similarly for the corresponding types.
I'll follow up with a couple uses.
committed,
Andrew
