couple of questions

[Bernhard Reutner-Fischer]

Hi there!

A couple of questions about nits

1) last_stmt
wouldn't it be more efficient if tree-cfg.c:: last_stmt() would
gimple_seq_last_nondebug_stmt (bb_seq (bb)) ? That would set stmt=NULL
only after the loop it seems..

2) msp430 TARGET_PROMOTE_PROTOTYPES hook
AFAICS msp430_promote_prototypes could be deleted, the default does the
same.

3) Fortran EQUIVALENCE
In fortran there is an EQUIVALENCE stmt. I'm wondering if this is (or
should be) used in PTA, the alias oracle and/or somewhere else?
"The EQUIVALENCE statement specifies that two or more variables or
arrays in a program unit share the same memory."

4) c++ frontend redundant store
cp_parser_set_decl_spec_type sets any_specifiers_p = true
unconditionally, so setting it again at least in
cp_parser_decl_specifier_seq is redundant.

stage 1 material i assume iff they hold (?).

thanks,
