Hey everyone,
I'm trying to compile a C++ file to SSA (single static assignment) and
this should be possible with g++ as gcc from 4 onwards includes this
facility (developer.apple.com/documentation/Darwin/Reference/ManPages/
man1/i686-apple-darwin9-g++-4.0.1.1.html) but i have not been able to
do it with gcc 4.0.1 or 4.2.1.
Is this a mac issue or a me issue?
i'm compiling with the -fdump-tree-ssa switch.
If i compile with -fdump-tree-all the folowing files appear but
no .ssa file :-(
helloc.c.003t.original\
helloc.c.004t.gimple\
helloc.c.007t.vcg\
helloc.c.017t.useless\
helloc.c.020t.lower\
helloc.c.021t.eh\
helloc.c.022t.cfg\
helloc.c.023t.cplxlower0\
helloc.c.024t.veclower\
helloc.c.026t.fixupcfg\
Any ideas would be great.
Cheers,
Rob.

Turn on the optimizer with -O.
