Bug ID: 96608
Summary: Build failure due to cast to type long on MinGW
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: markus.boeck02 at gmail dot com
Target Milestone: ---
Current trunk (revision 808f4dfeb3a95f50f15e71148e5c1067f90a126d) fails when
using the MinGW target due to a few casts to the type long which is 32 bit on
Windows. Following compiler errors appear:
In file included from ../../gcc/analyzer/checker-path.cc:51:
../../gcc/analyzer/store.h: In member function 'hashval_t
ana::symbolic_binding::hash() const':
../../gcc/analyzer/store.h:271:41: error: cast from 'const ana::region*' to
'long int' loses precision [-fpermissive]
271 | return (binding_key::impl_hash () ^ (long)m_region);
| ^~~~~~~~~~~~~~
With the same error appearing roughly 10 times through the code base.
Compiler used was GCC 10.2.1.
