Bug ID: 87417
Summary: [9 regression] Internal error: abort in
attr_alt_intersection, at genattrtab.c:2357
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: iii at linux dot ibm.com
Target Milestone: ---
Host: i386-pc-solaris2.11, sparc-sun-solaris2.11
Target: i386-pc-solaris2.11, sparc-sun-solaris2.11
Build: i386-pc-solaris2.11, sparc-sun-solaris2.11
Between 20180922 (r264503) and 20180924 (r264537), both Solaris/SPARC and
Solaris/x86
bootstrap got broken (already in stage1):
genattrtab: Internal error: abort in attr_alt_intersection, at
genattrtab.c:2357
make[3]: *** [Makefile:2364: s-attrtab] Error 1
This is obviously due to
2018-09-24 Ilya Leoshkevich <i...@linux.ibm.com>
* genattrtab.c (mk_attr_alt): Use alternative_mask.
(attr_rtx_1): Adjust caching to match the new EQ_ATTR_ALT field
types.
(check_attr_test): Use alternative_mask.
(get_attr_value): Likewise.
(compute_alternative_mask): Use alternative_mask and XWINT.
(make_alternative_compare): Use alternative_mask.
(attr_alt_subset_p): Use XWINT.
(attr_alt_subset_of_compl_p): Likewise.
(attr_alt_intersection): Use alternative_mask and XWINT.
