Bug ID: 94116
Summary: GCC regression - unexpected AST of kind lrotate_expr
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: antonio.di.monaco at sap dot com

Since commit aaa26bf496a646778ac861aed124d960b5bf549f, "c++: Use constexpr to
avoid wrong -Wsign-compare (PR90691)", GCC 10 fails to compile the following
code:
main.cpp:
#pragma GCC diagnostic error "-Wfloat-conversion"
int main() {
unsigned long a;
((a >> 50| a << 14) * 0xDEADBEEFDEADBEEFULL;
}
g++ -std=c++17 -Werror -Wall -o main.o -c main.cpp
main.cpp: In function ‘int main()’:
main.cpp:5:25: sorry, unimplemented: unexpected AST of kind lrotate_expr
5 | ((a >> 50| a << 14) * 0xDEADBEEFDEADBEEFULL;
| ^~~~~~~~~~~~~~~~~~~~~
main.cpp:5: confused by earlier errors, bailing out
