Summary: [4.6 regression] incorrect scalarization (3)
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: [email protected]
ReportedBy: [email protected]
The fix for PR tree-opt/44972 has introduced regressions in Ada, specifically:
(sra_modify_assign): Removed ref_expr_for_all_replacements_p checks,
checks for return values of build_ref_for_offset.
This is a third example, potentially a duplicate of PR tree-opt/46351, but it
can be reproduced on 32-bit targets:
e...@atlantis:~/build/gcc/native32> gcc/xgcc -Bgcc -S -O opt11.adb
+===========================GNAT BUG DETECTED==============================+

GCC error:|
| in build_ref_for_offset, at tree-sra.c:1345 |

The testcase is suitable for addition to the gnat.dg testsuite.
