Hi,
This patch wants to fix PR66552 on gimple and optimizes (x shift (n mod C))
to (x shift (n bit_and (C - 1))) when C is a constant and power of two as
discussed in PR66552.
The regression testing for the patch was done on GCC mainline on
powerpc64le-unknown-linux-gnu (Power 9 LE)
with no
There have been various ICEs with -fanalyzer involving unhandled tree
codes in region_model::get_lvalue_1; PR analyzer/93388 reports various
others e.g. for IMAGPART_EXPR, REALPART_EXPR, and VIEW_CONVERT_EXPR seen
when running the testsuite with -fanalyzer forcibly enabled.
Whilst we could impleme
This patch improves the wording of the state-transition event (1) in
the -Wanalyzer-null-dereference diagnostic for:
void test (void)
{
int *p = NULL;
*p = 1;
}
taking the path description from:
‘test’: events 1-2
|
|5 | int *p = NULL;

Hi Honza and all,
I updated the patch a little as below. Bootstrap and regtest are ok
on powerpc64le.
Is OK for trunk?
Thanks for comments.

This patch to libgo arranges to install internal/reflectlite.gox.
This makes it possible to use gccgo to bootstrap Go 1.14. If we don't
install this, gccgo can't compile the sort package, which expects to
be able to import this internal package. This fixes GCC PR go/93679.
