any recent changes to gcc test builds

[Joel Sherrill]

Hi,

I am confused at the gcc test results for RTEMS
over the weekend.  I have 1000s of failures
across all the targets which look like this:

Executing on host: /home/joel/test-gcc/b-gcc1-sparc/gcc/xgcc 
-B/home/joel/test-gcc/b-gcc1-sparc/gcc/ 
/home/joel/test-gcc/gcc-svn/gcc/testsuite/gcc.c-torture/execute/930930-1.c  
-w  -O3 -fomit-frame-pointer -funroll-loops  -DSTACK_SIZE=2048 
-B/home/joel/test-gcc/bsp-install/sparc-rtems4.10/sis/lib/ -specs 
bsp_specs -qrtems -mcpu=cypress 
/home/joel/test-gcc/b-gcc1-sparc/rtems_gcc_main.o  -lm   -o 
/home/joel/test-gcc/b-gcc1-sparc/gcc/testsuite/gcc/930930-1.x4    
(timeout = 300)
/home/joel/test-gcc/install/sparc-rtems4.10/bin/ld: cannot find -lm
collect2: ld returned 1 exit status

I haven't changed the configure command in the test script
and there are lots of libm.a's in the tree.  The command
just doesn't seem to be picking up the directory with libm.a.

Any ideas?

I fixed a bug in Janis' GCC_EXEC_PREFIX testsuite cleanup:
<http://gcc.gnu.org/ml/gcc-patches/2009-03/msg00970.html>.

Not that I see why this'd have any bearing on your failures;
-B's should be translated to -L's and the (presumably present)
 set_board_info ldflags   "[libgloss_link_flags] [newlib_link_flags]"
in your <board>.exp should help finding the newlib libraries.
(Hm, maybe I presumed too much and you don't have that!)

brgds, H-P

No.  I don't have those in my board.exp:

set_board_info cflags  "-B${RTEMS_MAKEFILE_PATH}/lib/ -specs bsp_specs 
-qrtems -mcpu=603e"
set_board_info ldflags "${RTEMS_CONFIG_OBJ}"

Where do I need to add those?  Can you point me
to examples?

I have attached the complete rtems-powerpc-psim.exp
in case that helps.  It isn't very large.

Thanks.

Those should find ${RTEMS_MAKEFILE_PATH}/lib/libm.a which might
or might not be what you want.

I'd grep among the other baseboards for numerous examples, in
the dejagnu installation, subdir baseboards.  In case you have
no clue where it is on the system where you test, you'll see it
as:
...
Using <dejagnu_installation_root>/config/sim.exp as generic interface file for target.
...

when running the test-suite.

brgds, H-P

Not. :)  That only points to RTEMS libraries for a particular
board.

Fixed and closed the single PR I was testing when I
ran into this.

Thanks.
