Hi,
just more removal of conditional compilation.
series run through config-list.mk, and each patch individually bootstrapped on
x86_64-linux-gnu. I think this is still preapproved so committed.
Trev
tbsaunde (4):
always define HAVE_conditional_execution
remove another #if for HAVE_cc0
always define HAVE_peephole2
add default for CONSTANT_ALIGNMENT
