Hi,
I have a small problem. I am making a new pass for my gcc, and some of my
adds are deleted by optimization passes.
here is the code i add :
t = builtin_decl_explicit (BUILT_IN_ACC_SETUPARGUMENT);
g = gimple_build_call(t,
3,
build1(ADDR_EXPR, integer_ptr_type_node, length),
build_int_cst(integer_type_node,TREE_INT_CST_LOW(TYPE_SIZE_UNIT
(TREE_TYPE (tmp_result)))),
offset
);
gsi_insert_before (&gsi, g, GSI_SAME_STMT);
you see, the variable length wich is actually "length.0" ->
gimple_omp_for_final() is renamed by ssa pass in length_1(D)
But, here is an ADDR_EXPR of length, and the optimization don't rename it,
so it points to the wrong variable because length.0 is not used anymore
after the optimizations.
I want to know if there is a way to prevent the compiler from optimizing
this code with a flag in my code for example ?
Thanks in advance !
