Subject: Add a fun parameter to three stmt_could_throw... functions
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=36bbc05db8ef71811a7b925bbb862d0b1c3b5b89;p=gcc.git

Add a fun parameter to three stmt_could_throw... functions

This long patch only does one simple thing, adds an explicit function
parameter to predicates stmt_could_throw_p, stmt_can_throw_external
and stmt_can_throw_internal.

My motivation was ability to use stmt_can_throw_external in IPA
analysis phase without the need to push cfun.  As I have discovered,
we were already doing that in cgraph.c, which this patch avoids as
well.  In the process, I had to add a struct function parameter to
stmt_could_throw_p and decided to also change the interface of
stmt_can_throw_internal just for the sake of some minimal consistency.

In the process I have discovered that calling method
cgraph_node::create_version_clone_with_body (used by ipa-split,
ipa-sra, OMP simd and multiple_target) leads to calls of
stmt_can_throw_external with NULL cfun.  I have worked around this by
making stmt_can_throw_external and stmt_could_throw_p gracefully
accept NULL and just be pessimistic in that case.  The problem with
fixing this in a better way is that struct function for the clone is
created after cloning edges where we attempt to push the yet not
existing cfun, and moving it before would require a bit of surgery in
tree-inline.c.  A slightly hackish but simpler fix might be to
explicitely pass the "old" function to symbol_table::create_edge
because it should be just as good at that moment.  In any event, that
is a topic for another patch.

I believe that currently we incorrectly use cfun in
maybe_clean_eh_stmt_fn and maybe_duplicate_eh_stmt_fn, both in
tree-eh.c, and so I have fixed these cases too.  The bulk of other
changes is just mechanical adding of cfun to all users.

Bootstrapped and tested on x86_64-linux (also with extra NULLing and
restoring cfun to double check it is not used in a place I missed), OK
for trunk?

Thanks,

Martin
