Thanks for submitting this patch.  Patch itself looks simple, but
doesn't meet some requirements for patch submission.  In short,
please have a look at https://sourceware.org/gdb/wiki/ContributionChecklist

Each entry should be tab-prefixed.  A space is missing before "(".

Should be tab-prefixed.

The period after "descriptors" should be removed.  It is better to say

"Skip symbols without location descriptors or don't have type", or
whatever "pdi->has_type == 0" stands for.

pdi->has_type is a boolean to me, we can use "!pdi->has_type".

Attaching a new file gets the review a little hard.  Please generate a
diff including your changes above and this new file.  That is easier
for people to review.  Write the changelog in the e-mail together,

gdb:

2014-01-24  Jun Gong  <heixia108@gmail.com>

	* dwarf2read.c(add_partial_symbol): Add symbol whose field
	'has_type' has been set to partial symbol table.

gdb/testsuite:

2014-01-24  Jun Gong  <heixia108@gmail.com>

      * gdb.dwarf2/const-var.exp: New file.

and attach the patch including the changes in dwarf2read.c and new test
cases in the e-mail.
