Summary: LTO ICE on PPC64le
Product: gcc
Version: 9.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto

Target Milestone: ---
Hi,
we are trying to compile a few larger HPC libraries and applications with GCC
and CMake using LTO support on Power9 (ppc64le). With the available GCC
versions we have on Summit (OLCF), 6.4.0 - 9.1.0, we reproducibly tap into an
ICE in the LTO step.
GCC 6.4.0:
lto1: internal compiler error: invalid resolution in the resolution file
0x101d0e93 lto_resolution_read
/sw/summit/gcc/6.4.0/src/gcc-6.4.0/gcc/lto/lto.c:1923
0x101d0e93 lto_file_read
/sw/summit/gcc/6.4.0/src/gcc-6.4.0/gcc/lto/lto.c:2092
0x101d0e93 read_cgraph_and_symbols
/sw/summit/gcc/6.4.0/src/gcc-6.4.0/gcc/lto/lto.c:2806
0x101d0e93 lto_main()
/sw/summit/gcc/6.4.0/src/gcc-6.4.0/gcc/lto/lto.c:3310
GCC 7.4.0:
lto1: internal compiler error: invalid resolution in the resolution file
0x101a589b lto_resolution_read
/sw/summit/gcc/7.4.0/src/gcc-7.4.0/gcc/lto/lto.c:1939
0x101a589b lto_file_read
/sw/summit/gcc/7.4.0/src/gcc-7.4.0/gcc/lto/lto.c:2108
0x101a589b read_cgraph_and_symbols
/sw/summit/gcc/7.4.0/src/gcc-7.4.0/gcc/lto/lto.c:2824
0x101a589b lto_main()
/sw/summit/gcc/7.4.0/src/gcc-7.4.0/gcc/lto/lto.c:3341
GCC 9.1.0:
lto1: internal compiler error: invalid line in the resolution file
0x101915bb lto_resolution_read
/tmp/belhorn/gcc-build-9.1.0-alpha+20190716/gcc-9.1.0/gcc/lto/lto.c:1957
0x101915bb lto_file_read
/tmp/belhorn/gcc-build-9.1.0-alpha+20190716/gcc-9.1.0/gcc/lto/lto.c:2142

The problem occurs with the library https://github.com/ornladios/ADIOS2 or the
application https://github.com/ECP-WarpX/WarpX independently, given one adds
set_property(TARGET WarpX PROPERTY INTERPROCEDURAL_OPTIMIZATION TRUE)
to the latter's CMakeLists.txt, anywhere after add_executable(WarpX) .
We try to derive a smaller example but have not arrived at one yet. Maybe the
ICE line numbers above can hint us where to look?
