testsuite questions.

[Manoj Iyer <manjo@austin.ibm.com>]

I am trying to compare the test results from the GDB I built vs the GDB
installed on the system. I found that if I set GDB "/usr/bin/mygdb" in the
testcases.exp file, the testcase uses my custom GDB instead of searching
for one in src/gdb/.

1. Is there any enviroment variable that I can set to make the testcase
use my custom GDB, for instance the one in /usr/local/bin/gdb?

Also, when the testcase '.c' file is compiled, the compile line ignores
any CFLAGS or CC variables that I set, I found that gdb_compile and
target-compile use CFLAGS_FOR_TARGET and CC_FOR_TARGET varialbles. I would
like to use my custom compiler and compile the testcase as a 64bit binary
(-m64 flag).

2. Is there any enviroment variable I can use to control the value of
these variables?

The intention is to disconnect the testsuite from using the system
utilities and GDB that gets built, but use the testcase to test a
different binary of GDB that I have in a separate local/system directory.
This way I can compare the test results from system gdb (or any gdb binary
forthat matter)  with the one that I downloaded from cvs.

Any input is greatly appreciated.

Thanks
