Hi,
I'm encountering a problem cross-compiling GCC (trunk) for Blackfin, using
uClibc. A semi-recent change in GCC has resulted in sys/ucontext.h and GCC's
generated insn-constants.h being included at the same time when building
libgcc. This results in name clashes with the enum of registers in the
gregset_t array. For more background, see the GCC PR:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47779
The originally suggested fix is very messy and Bernd suggests the fix should be
made in uClibc, which I agree with. However I'm not sure what the best way to
do it is. Will simply disabling this enum when IN_LIBGCC2 be sufficient?
Thanks,
Stu
