Bug #: 51510
Summary: [4.6/4.7 regression] gcc for arm-linux-gnueabi ICEs on
gcc.c-torture/execute/20050713-1.c due to
PR50074+PR51323 fix
Classification: Unclassified
Product: gcc
Version: 4.6.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: regression
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: mikpe@it.uu.se
The PR50074+PR51323 fix, r182112 on 4.6 branch, caused a test suite regression
on arm-linux-gnueabi:
+FAIL: gcc.c-torture/execute/20050713-1.c compilation, -O2 (internal compiler
error)
+UNRESOLVED: gcc.c-torture/execute/20050713-1.c execution, -O2
+FAIL: gcc.c-torture/execute/20050713-1.c compilation, -Os (internal compiler
error)
+UNRESOLVED: gcc.c-torture/execute/20050713-1.c execution, -Os
because the compiler now ICEs:
20050713-1.c: In function 'bar3':
20050713-1.c:38:3: internal compiler error: in calculate_allocation, at
vec.c:183
The same ICE also happens with 4.7-20111210.
