--- Comment #1 from Nicholas Krause <xerofoify at gmail dot com> ---
Hi,
This does not seem to be happening in the middle end but in RTL expand. I've
tried on x86_64 trunk and now powerpc. Seems to only happen on PowerPC now as
seen here:
test.cpp: In function ‘int main(int, char**)’:
test.cpp:33:23: sorry, unimplemented: passing too large argument on stack
33 | result = mulm(m1, m2);
| ^
during RTL pass: expand
g++: internal compiler error: Segmentation fault signal terminated program
cc1plus
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.
I'm not aware of stack size limitations on Power so I'm CCed the maintainer to
take a look. Not sure if this occurs on other architectures in expand like ARM
as well. Segher would you please take a look at this for me.
