Hi,
powerpc-rtems does not compile on the head due
to what appear to be changes in the way CPU
features are represented for the arguments.
The compilation error is:
/users/joel/test-gcc/gcc-svn/gcc/config/rs6000/rs6000.c -o rs6000.o
/users/joel/test-gcc/gcc-svn/gcc/config/rs6000/rs6000.c: In function
‘rs6000_option_override_internal’:
/users/joel/test-gcc/gcc-svn/gcc/config/rs6000/rs6000.c:2826:3: error:
‘rs6000_explicit_options’ undeclared (first use in this function)
/users/joel/test-gcc/gcc-svn/gcc/config/rs6000/rs6000.c:2826:3: note:
each undeclared identifier is reported only once for each function it
appears in
At top level:
The code is in rtems.h is currently:
if (TARGET_E500) \
{ \
if (TARGET_HARD_FLOAT && !rs6000_explicit_options.float_gprs) \
rs6000_float_gprs = 1; \
if (rs6000_float_gprs != 0 && !rs6000_explicit_options.spe) \
rs6000_spe = 1; \
if (rs6000_spe && !rs6000_explicit_options.spe_abi) \
rs6000_spe_abi = 1; \
} \
I think that changes to something like:
if (TARGET_E500) \
{ \
if (!global_options_set.x_rs6000_float_gprs) \
rs6000_float_gprs = 1; \
if (!global_options_set.x_rs6000_spe) \
rs6000_spe = 1; \
if (!global_options_set.x_rs6000_spe_abi) \
rs6000_spe_abi = 1; \
} \
That compiles but I wanted a sanity check that it is the right
transformation.
Thanks.

I am not sure, either, but your code matches what other files being
found in GCC trunk.
I so far have been experimenting with a less intrusive patch:

It looks like this was missed by Joseph during his change.

Yes, this is the right transformation. Here is an untested patch that fixes
it:
2011-11-08 Michael Meissner <meissner@linux.vnet.ibm.com>
* config/rs6000/rtems.h (SUBSUBTARGET_OVERRIDE_OPTIONS): Use
global_options_set instead of rs6000_explicit_options, which was
removed on May 5th.
