Summary: ICE in gen_add2_insn, at optabs.cc:5579 in XGCC
16.1.0, host mac os 14.8.7, target RX
Product: gcc
Version: 16.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

Code snippet that causes the ICE
When I attempt to compile the attached main.cc with GCC 16.1.0 rx with the
command arguments as follows:
/opt/gcc-16.1.0-rx-none-elf/libexec/gcc/rx-none-elf/16.1.0/cc1plus main.cpp
-mcpu=rx600 -mint-register=4 -g -Wall -std=gnu++14 -fpu -o main.o
... I'll get an ICE:
/opt/gcc-16.1.0-rx-none-elf/rx-none-elf/include/c++/16.1.0/bits/std_function.h:427:26:
internal compiler error: in gen_add2_insn, at optabs.cc:5579
427 | : _Function_base()
| ^
/opt/gcc-16.1.0-rx-none-elf/libexec/gcc/rx-none-elf/16.1.0/cc1plus main.cpp
-mcpu=rx600 -mint-register=4 -g -Wall -std=gnu++14 -fpu -o main.o
Please submit a full bug report, with preprocessed source (by using
-freport-bug).
See <https://gcc.gnu.org/bugs/> for instructions.
NOTE: I have learned that the compiler switch '-mint-register=4' will have an
impact to this. If I remove it then the ICE does not happen!
This issue is reproducible.
