Re: [PATCH] gdb passes and returns incorrect values when dealing with small array on Sparc

Hi Vladimir,

gdb development happens on a separate list - gdb-patches@.  Please resend
the patch there.  TIA!


A question I'll have is whether this had any observable effect in testsuite
results, other than "no regressions".  I.e., whether there were progressions,
or whether we're missing testsuite coverage.

6 tests ( from gdb/testsuite/gdb.base/gnu_vector.exp) failed on sparc64-Linux and on sparc-Solaris in 32- and 64-bit mode.
Now all these tests passed.

gdb/testsuite/gdb.base/gnu_vector.exp has 117 different cases for small (and not small) arrays and structures.
I think we don't need an additional test in gdb/testsuite.

	gdb has a special type (TYPE_CODE_ARRAY) to support the gcc extension
	TYPE_CODE_ARRAY is handled incorrectly for both (32- and 64-bit) modes on Sparc machines.

	Tested on sparc64-linux-gnu and sparc-solaris (32- and 64-bit mode).
	No regressions.

	* gdb/sparc-tdep.c (sparc_structure_return_p): New function.
Also, please drop "gdb/" here.  Filename entries in ChangeLogs
are relative to the ChangeLog file path.
