405-mullhw-1.c is invoked with -mcpu=405 and directly scans the
assembly language output -- does not try to create an object file or run
an executable. If that fails, you should check if the RTEMS configuration
somehow is inhibiting generation of the mullhwX instruction and
TARGET_MULHW flag.
Also, if you use a multilib option in testing, that option goes on the
command line *after* the options specified in dg-options. The tests may
need to use dg-skip-if to skip them if any CPU option other than the one
in the test is explicitly specified (so it would be tested if no explicit
-mcpu option is used, or if -mcpu=405 is the multilib option being
tested).
Are you thinking of something roughly like this?
/* { dg-skip-if "" { { !-mcpu=405 } } { "*" } { "" } } */
Would that work if somehow two -mcpu flags were on the line?
This is the command line in question:
Executing on host: /home/joel/work-gnat/svn/b-gcc1-powerpc/gcc/xgcc
-B/home/joel/work-gnat/svn/b-gcc1-powerpc/gcc/
/home/joel/work-gnat/svn/gcc/gcc/testsuite/gcc.target/powerpc/405-nmaclhw-2.c
-O2 -mcpu=405 -DSTACK_SIZE=2048 -fno-show-column -S
-B/home/joel/work-gnat/svn/bsp-install/powerpc-rtems4.9/psim/lib/ -specs
bsp_specs -qrtems -mcpu=603e -o 405-nmaclhw-2.s (timeout = 300)
FWIW This seems pretty tedious. My grep didn't turn up that
many under gcc.target and I know I have more failures of this
type than I saw uses of dg-skip-if. If the above is what you think
is right, I can take the exact CPU option tested and then make the
test only valid if that CPU option is used. OK?
