[Fwd: [RFA] Dependency of gdb on tcl/tk]

[Andrew Cagney <ac131313@cygnus.com>]

John,

I'm forwarding this (as you can tell :-) to the insight list.  Given 
this really affects insight I think they are the ones to comment.

For GDB, the only thing I can think of is that the dependency be 
conditional on insight sources being present.

Hello,

This patch moves the ``libgdb'' library declarations to a separate file 
- gdb.h.  This brings the source code into line with the documentation! 
  In the process I delete a two year old FIXME :-)

I intend committing this tweek befor the 5.1 branch.

	thoughts,

Subject: [rfa] Attempt #3: Eliminate HOST_*_FORMAT from arm-*tdep.c

Hello,

Attatched is another attemt at eliminating the HOST_*_FORMAT references 
in arm-tdep.c and arm-linux-tdep.c.  I'm definitly getting closer!

This time, I also ``fixed'' the functions convert_to_extended() and 
convert_from_extended() to use portable floatformat_*() functions.

With the patch applied testing on a big-endian host using the arm-sim 
target suggests things do indeed imrove.  The tests:

gdb.base/callfuncs.exp: p t_float_values
gdb.base/callfuncs.exp: p t_float_values2
gdb.base/callfwmall.exp: p t_float_values
gdb.base/callfwmall.exp: p t_float_values2

all started passing.  At the same time I didn't see any regressions.
Interestingly, testing on a little endian host showed no change in the 
test results.

There is one FIXME.  The code always uses floatformat_arm_ext.  I'm 
windering if there needs to be both floatformat_arm_ext_big and 
floatformat_arm_ext_little.  Anyone know the exact format used when 
storing BE/LE extended floats on the arm architecture?

Anyway, I'm hopeing this is sufficient improvement over the previous 
mess to go in.

I discovered a little foobar.  sh_gdbarch_init was using the macro
NUM_REGS, which was being defined for the given arch in the same
call. It would pick up the value of whatever the
current_gdbarch->NUM_REGS would be. current_gdbarch is NOT the arch we
are defining.

	* sh-tdep.c (sh_gdbarch_init): Use SH_DEFAULT_NUM_REGS instead of
	NUM_REGS.
	(SH_DEFAULT_NUM_REGS): Define.
