Hi Nick,
Thanks for reviewing my patch and I do appreciate you for pointing
Out my mistakes. Thanks for that.
Here I have separated down individual patches this will be the
first of the series.
This patch will enable the maxq target to
differentiate between machine types( MAXQ10 and MAXQ20 ).
----------- Change Log ---------------------------------
2004-12-28 Inderpreet Singh <inderpreetb@noida.hcltech.com>
bfd/
* archures.c: define bfd_mach_maxq10 and bfd_mach_maxq20.
* bfd-in2.h: Likewise.
* coffcode.h: Likewise.
* cpu-maxq.c: arch_info_type defined for maxq10 and maxq20.
gas/config
* tc-maxq.c (md_pseudo_table): added new pseudo ops for maxq10
and maxq20.
(maxq_target): added function to set the arch. type.
--------------------------------------------------------------
Thanks,
Inder

Thanks - I have applied this patch but I still had to fix up a few problems:
1) You did not supply a ChangeLog entry for the changes to the
include/coff/maxq.h file.
2) You added a function called "compatible" in bfd/cpu-maxq.c that is
not used.
3) The field "the_default" for the maxq10 architecture description in
bfd/cpu-maxq.c was set to true even when in fact it is not the default.
Cheers
Nick

Hi,
I am attaching a patch for the maxq-target with the following changes:
1. Added variants support for the target maxq10 and maxq20.
2. Fixed problem with relative address handling.
3. Testcases fix for the above problem.
I am also including a patch for the config.sub file as I require
This to bring the binutils in sync. With the gcc port for maxq.
This is the third time I am posting this patch.
I have even tried Sending mails with this patch to
config-patches@gnu.org
But have received no reply or even a commit verification
Please commit t <<patch-binutils-27122004>> hese changes.
And can anyone please tell me what needs to be done if I want my name in
the
Maintainers list for the maxq port?

Sorry - but we (binutils) cannot accept or commit the patch to the top
level configure files. You will have to keep trying the
config-patches@gnu.org address.

Essentially you need to demonstrate three things:
a) A willingness to take on the responsibility
b) Knowledge of the particular target
c) The programming skills to produce good code that conforms to the
GNU Coding Standard
Thanks for generating this patch. There are several problems with it
however:
*) The patch fixes a problem and adds a new feature. We really
prefer patches to just do one thing - fix one problem, add one new
feature, etc. It makes hunting down problems with patches much easier
if they just do one thing.
*) You added an inclusion of "coff/external.h" to the file
bfd/coff-maxq.c but you did not update the dependency description in
bfd/Makefile.am. Thus if someone modifies coff/external.h at a later
date coff-maxq.o will not (automatically) be rebuilt which could lead to
problems.
*) There are still places where the GNU Coding Standard is not being
followed. In particular you should always leave a single white space
between a control operator and the opening parenthesis of its argument
list. So for example this:
switch(bfd_get_mach (abfd))
should be:
switch (bfd_get_mach (abfd))
One section was particularly bad. The new function maxq_end() in
gas/config/tc-maxq.c was provided as:
+ void
+ maxq_end()
+ {
+ if(max_version==10)
+ {
+ bfd_set_arch_mach (stdoutput, bfd_arch_maxq,bfd_mach_maxq10);
+ }
+ else
+ {
+ bfd_set_arch_mach (stdoutput, bfd_arch_maxq,bfd_mach_maxq20);
+ }
+
+ }
arelent *
This should have been:
+ void
+ maxq_end (void)
+ {
+ if (max_version == 10)
+ bfd_set_arch_mach (stdoutput, bfd_arch_maxq, bfd_mach_maxq10);
+ else
+ bfd_set_arch_mach (stdoutput, bfd_arch_maxq, bfd_mach_maxq20);
+ }
+
arelent *
Note the extra whitespaces helping to separate out the code into various
regions as well as the removal of the redundant curly braces.
*) It adds a static function "compatible" to the file bfd/cpu-maxq.c,
but this function is never used. In addition the field "the_default" of
the new maxq10 bfd_arch_info structure definition is set to TRUE when it
should be FALSE.
*) The patch to include/coff/maxq.h defines new flags for the MAXQ10
and MAXQ20 processors. It seems strange however that the value for
F_MAXQ10 should be set to 0x0030 rather than just a single bit. Is this
deliberate ? If so, there ought to be a comment explaining why.
*) The change to one of the lines in opcodes/maxq-dis.c looks very
strange:
info->fprintf_func (info->stream, " #%02xh.%d",
! grp.src, grp.bit_no);
--- 684,690 ----
info->fprintf_func (info->stream, " #%02xh.%d",
! (grp.src, SRC), grp.bit_no);
What is the purpose of evaluating grp.src only to ignore its value
and instead use the constant SRC ?
I hope that you will consider these comments and produce a revised patch.
Cheers
Nick
