From: Stu Grossman Date: Fri, 12 Apr 1996 16:53:08 +0000 (+0000) Subject: * defs.h: Define TARGET_{FLOAT DOUBLE LONG_DOUBLE}_FORMAT X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c6fbd98bed167d79e49c0d4a38b5432853f11799;p=binutils-gdb.git * defs.h: Define TARGET_{FLOAT DOUBLE LONG_DOUBLE}_FORMAT defaults for bi-endian targets. Replace function pointers for floatformat routines with macros. No need for these to be runtime selectable. * findvar.c: Get rid of floatformat function pointers. Use macros in extract_floating and store_floating. * remote-nindy.c (nindy_fetch_registers nindy_store_registers): Use floatformat macros. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 52001c05572..94e1ebac110 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,14 @@ +Fri Apr 12 09:45:29 1996 Stu Grossman (grossman@critters.cygnus.com) + + * defs.h: Define TARGET_{FLOAT DOUBLE LONG_DOUBLE}_FORMAT + defaults for bi-endian targets.
