RFA: gdbarch IEEE_FLOAT
- To: Andrew Cagney <cagney at cygnus dot com>, David Taylor <taylor at cygnus dot com>
- Subject: RFA: gdbarch IEEE_FLOAT
- From: Jim Blandy <jimb at zwingli dot cygnus dot com>
- Date: Mon, 10 Apr 2000 22:02:26 -0500 (EST)
- CC: gdb-patches at sourceware dot cygnus dot com
The changes to the tm.h files are trivial, so I don't think this
really needs approval from the various platform maintainers.
2000-04-10 Jim Blandy <jimb@redhat.com>
Bring IEEE_FLOAT under gdbarch's control.
* gdbarch.sh (IEEE_FLOAT): New entry.
* gdbarch.c, gdbarch.h: Regenerated.
* valprint.c (IEEE_FLOAT): Provide a default #definition for this.
(print_floating): Use IEEE_FLOAT as if it were an expression; use
the code specific to IEEE-format numbers whenever the value of
IEEE_FLOAT is non-zero.
* config/a29k/tm-a29k.h, config/alpha/tm-alpha.h,
config/arc/tm-arc.h, config/arm/tm-arm.h, config/fr30/tm-fr30.h,
config/h8300/tm-h8300.h, config/i386/tm-i386.h,
config/i960/tm-i960.h, config/m88k/tm-m88k.h,
config/mips/tm-mips.h, config/pa/tm-hppa.h,
config/sparc/tm-sparc.h, config/delta/tm-delta.h,
config/frv/tm-frv.h (IEEE_FLOAT): For all ports that #define
IEEE_FLOAT, make sure they give it the value (1).
