[PATCH] Finish int_const_binop partial transition
- From: Richard Guenther <rguenther at suse dot de>
- To: gcc-patches at gcc dot gnu dot org
- Date: Tue, 3 May 2011 16:06:38 +0200 (CEST)
- Subject: [PATCH] Finish int_const_binop partial transition
There are two callers left that call int_const_binop with a 1 notrunc
argument causing non-canonicalized INTEGER_CSTs to be built. One
is group_case_labels_stmt in tree-cfg.c which can simply use
double_ints (which is what all code using 1 notrunc should do,
similar to old code building INTEGER_CSTs with a NULL type). The
other one is quite convoluted in our special friend extract_muldiv_1.
I attacked that by simply expanding the int_const_binop call
inline and massaging it until it didn't look gross anymore. I
left intact most of the structure (which also shows some inconsitency
in sizetype handling). The goal was no functional change here - so
I hope I succeeded in a 1:1 transformation at this place - 2nd
eyes welcome.
A bootstrap and test with an assertion that we call int_const_binop
with zero notrunc and the two cases transformed nearly finished, a
bootstrap and regtest with the full patch changing all callers is
still running on x86_64-unknown-linux-gnu.
In a followup the extract_muldiv_1 case could be made consistent
with respect to TYPE_IS_SIZETYPE which would allow quite some
simplification in the overflow conditionals ...
Thanks,
Richard.
