Bug ID: 115398
Summary: [15 regression] RTL flag check:
CONSTANT_POOL_ADDRESS_P used with unexpected rtx code
'plus' in get_pool_constant, at varasm.cc:4046
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: manuel.lauss at googlemail dot com
Target Milestone: ---
Created attachment 58384
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=58384&action=edit
compressed unreduced testcase
The attached unreduced testfile (from llvm-18.1.7) ICEs:
# g++ -m32 -O3 -mavx512f -c dep.ii
during RTL pass: split1
llvm/lib/Analysis/DependenceAnalysis.cpp: In constructor
'llvm::FullDependence::FullDependence(llvm::Instruction*, llvm::Instruction*,
bool, unsigned int)':
llvm/lib/Analysis/DependenceAnalysis.cpp:273:1: internal compiler error: RTL
flag check: CONSTANT_POOL_ADDRESS_P used with unexpected rtx code 'plus' in
get_pool_constant, at varasm.cc:4046
273 | }
| ^
"-O3 -mavx512f" are necessary to trigger it.
gcc version 15.0.0 20240608 (experimental)
