Bug ID: 58826
Summary: Runfail on CPU2006 436.cactusADM with after r203739
for core-avx2 target.
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ysrumyan at gmail dot com
To reproduce it is sufficient to compile only one source file -
StaggeredLeapfrog2.F which must be preprocessed. In rtl-dump after reload we
can see the following erroneous of instruction which try to write to RO
section:
(insn 10377 15507 10379 49 (set (mem/u/c:V4DF (symbol_ref/u:DI ("*.LC10")
[flags 0x2]) [3 S32 A256])
(reg:V4DF 27 xmm6 [10848])) 1158 {*movv4df_internal}
(nil))
The following options were used to compile:
-march=core-avx2 -Ofast -funroll-loops -fno-second-underscore
although the last option looks redundant.
